The operated area will be cleaner without dressing and will heal faster. The modified Widman flap facilitates instrumentation for root therapy. After administrating local anesthesia, profound anesthesia is achieved in the area to be operated. After this, the second or the sulcular incision is made from the bottom of the pocket till the crest of the alveolar bone. Position of the knife to perform the internal bevel incision. Vertical relaxing incisions are usually not needed. Periodontal flaps involve the use of horizontal (mesialdistal) and vertical (occlusalapical) incisions. There are two types of incisions that can be used to include interdental papillae in the facial flap: One technique includes semilunar incisions which are. An electronic search without time or language restrictions was . 1. In areas with thin gingiva and alveolar process. If extensive osseous recontouring is planned, an exaggerated incision is given. Sulcular incision is now made around the tooth to facilitate flap elevation. After the primary incision, tissue can now be retracted with the help of rat-tail pliers. The undisplaced flap is therefore considered an internal bevel gingivectomy. 11 or 15c blade. 1. The bleeding is frequently associated with pain. The incision is made. Contents available in the book .. Modified Widman flap and apically repositioned flap. They are also useful for treating moderate to deep periodontal pockets in the posterior regions. Sutures are placed to secure the flaps in their position. ), For the conventional flap procedure, the incisions for the facial and the lingual or palatal flap reach the tip of the interdental papilla or its vicinity, thereby splitting the papilla into a facial half and a lingual or palatal half (Figures 57-3 and. Contents available in the book .. Conventional flaps include the. The internal bevel incision may be a marginal incision (from the top of gingival margin) or para-marginal incision (at a distance from the gingival margin). Severe hypersensitivity. The incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. The pockets are measured with the periodontal probe, and a bleeding point is produced on the outer surface of the gingiva to mark the pocket bottom. Once bone sounding has been done, a gingivectomy incision without bevel is given using a periodontal knife to remove the tissue above the alveolar crest. Increase accessibility to root deposits for scaling and root planing, 2. Before we go into the details of the periodontal flap surgeries, let us discuss the incisions used in surgical periodontal therapy. The triangular wedge of the tissue, hence formed is removed. After suturing, the flap is adapted around the neck of the teeth with the help of moistened gauze. Horizontal incisions are directed along the margin of the gingiva in a mesial or distal direction. Conventional surgical approaches include the coronal flap, direct cutaneous incision, and endoscopic techniques. Access flap for guided tissue regeneration. The flap procedures on the palatal aspect require a different approach as compared to other areas because the palatal tissue is composed of a dense collagenous fiber network and there is no movable mucosa on the palatal aspect. Signs and symptoms may include continuous flow, oozing or expectoration of blood or copious pink saliva. Flap reflection till alveolar mucosa to mobilize the flap causes more post-operative pain and discomfort. The flap procedures on the palatal aspect require a different approach as compared to other areas because the palatal tissue is composed of a dense collagenous fiber network and there is no movable mucosa on the palatal aspect. The para-marginal internal bevel incision accomplishes three important objectives. These techniques are described in detail in. In this flap procedure, all the soft tissue, including the periosteum is reflected to expose the underlying bone. The periodontal pockets on the distal aspects of last molars, both in maxillary and the mandibular arches present a unique situation for which specific surgical designs have been advocated. Laterally displaced flap. The blade is pushed into the sulcus till resistance is felt from the crestal bone crest. 2. In areas with deep periodontal pockets and bone defects. 4. 74. The incisions given are the same as in case of modified Widman flap procedure. For the undisplaced flap, the internal bevel incision is initiated at or near a point just coronal to where the bottom of the pocket is projected on the outer surface of the gingiva (see Figure 59-1). After removing the wedge of the tissue the margins of the flap are undermined with the help of scalpel blades . Log In or, (Courtesy Dr. Kitetsu Shin, Saitama, Japan. The three different categories of flap techniques used in periodontal flap surgery are as follows: (1) the modified Widman flap; (2) the undisplaced flap; and (3) the apically displaced flap. Areas which do not have an esthetic concern. techniques revealed that 67.52% undergone kirkland flap, 20.51% undergone modified widman flap, 5.21% had papilla preservation flap, 2.25% had undisplaced flap, 1.55% had apically displaced flap and very less undergone distal wedge procedure which depicts that most commonly used flap technique was kirkland flap among other techniques. This technique offers the possibility ol establishing an intimate postoperative adaptation ol healthy collagenous connective tissue to tooth surlaces " and provides access for adequate instrumentation ol the root surtaces and immediate closure ol the area the following is an outline of this technique: The influence of tooth location on the outcomes of multiple adjacent gingival recessions treated with coronally advanced flap: A multicenter ReAnalysis study Article Jun 2019 Giovanni Zucchelli. 15 or 15C surgical blade is used most often to make this incision. 2014 Apr;41:S98-107. In 1965, Morris4 revived a technique described early during the twentieth century in the periodontal literature; he called it the unrepositioned mucoperiosteal flap. Essentially, the same procedure was presented in 1974 by Ramfjord and Nissle,6 who called it the modified Widman flap (Figure 59-3). Contents available in the book .. Refer to oral surgeon for biopsy ***** B. It differs from the modified Widman flap in that the soft-tissue pocket wall is removed with the initial incision; thus, it may be considered an internal bevel gingivectomy. The undisplaced flap and the gingivectomy are the two techniques that surgically remove the pocket wall. This incision is made 1mm to 2mm from the teeth. The periodontal flap surgeries have been practiced for more than one hundred years now, since their introduction in the early 1900s. Contents available in the book .. The area is then debrided for all the granulation tissue present and scaling and root planing of the root surfaces are carried out. 2011 Sep;25(1):4-15. The first step .

Suturing techniques. These meniscus tears are displaced into the tibia or femoral recesses and can be often difficult to diagnose intraoperatively. Clinical crown lengthening in multiple teeth. Modified Widman flap, The triangular wedge of the tissue, hence formed is removed. Step 3: The second, or crevicular, incision is made from the bottom of the pocket to the bone to detach the connective tissue from the bone. Click this link to watch video of the surgery: Areas where greater probing depth reduction is required. 6. Flaps are used for pocket therapy to accomplish the following: 1. Contents available in the book .. In addition, thinning of the flap should be performed with the initial incision, because it is easier to accomplish at this time than it is later with a loose, reflected flap that is difficult to manage. In a full-thickness flap, all of the soft tissue, including the periosteum, is reflected to expose the underlying bone. A periosteal elevator is inserted into the initial internal bevel incision, and the flap is separated from the bone. ( intently, the undisplaced flap is perhaps the most commonly performed type ol periodontal surgery. It is discarded after the crevicular (second) and interdental (third) incisions are performed (Figure 57-5). The margins of the flap are then placed at the root bone junction. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. Contents available in the book . The flap is sutured with interrupted or continuous sling sutures. The modified Widman flap procedure involves placement of three incisions: the initial internal bevel/ reverse bevel incision (first incision), the sulcular/crevicular incision (second incision) and the horizontal/interdental incision (third incision). The blade should be kept on the vertical height of the alveolus so that palatal artery is not injured. Contents available in the book .. To facilitate the close approximation of the flap, judicious osteoplasty, if required, is performed. Step 1:The pockets are measured with the periodontal probe, and a bleeding point is produced on the outer surface of the gingiva to mark the pocket bottom. What is a periodontal flap? Contents available in the book .. The incision is started from the greatest scallop of the gingiva around the tooth, which is usually present little distal to the mid-axis of the tooth in case of maxillary incisors and canines. Within the first few days, monocytes and macrophages start populating the area 37. Hereditary gingival fibromatosis (HGF), also known as idiopathic gingival hyperplasia, is a rare condition of gingival overgrowth. This is mainly because of the reason that all the lateral blood supply to . The Orban knife is usually used for this incision. Areas which do not have an esthetic concern. With this incision, the gingiva containing pocket lining is separated from the tooth surface. Kirkland flap method was the most commonly followed (60.47%), then it was modified widman flap (29.65%), undisplaced flap (6.39%) and distal wedge which was the lowest (3.48%). In this flap procedure, no ostectomy is performed; however, minor osetoplasty may be done to modify the undesired bony architecture. The objectives for the other two flap proceduresthe undisplaced flap and the apically displaced flapinclude root surface access and the reduction or elimination of the pocket depth. A new technique for arthroscopic meniscectomy using a traction suture, , 2015-02, ()KCI . In the present discussion, we discussed various flap procedures that are used to achieve these goals. The interdental incision is then given to remove the wedge of tissue that contains the pocket wall. Contents available in the book .. 5. Minimally invasive techniques have recently been described for the reduction of the isolated anterior frontal sinus fracture via a closed approach. This is a commonly used incision during periodontal flap surgeries. The undisplaced flap and gingivectomy are the two techniques that surgically removed the pocket wall. The esthetic and functional demands of maxillofacial reconstruction have driven the evolution of an array of options. The incision is carried around the entire tooth. A. This incision is indicated in the following situations. In this technique no. To preserve the present attached gingiva or even to establish an adequate strip of it, where it is narrow or absent. Continuous suturing allows positions. Along with removing the tissue above the alveolar crest, this incision also reveals the thickness of the soft tissue. There is a loud S1 The murmur is a mid-diastolic rumbling heard best at . The buccal and palatal/lingual flaps are reflected with the help of a periosteal elevator. This preview shows page 166 - 168 out of 197 pages.. View full document. As already stated, this technique is utilized when thicker gingiva is present. Contents available in the book . Areas which do not have an esthetic concern. Continuous, independent sling sutures are placed in both the facial and palatal areas (. A. The gingival margin is removed, and the flap is reflected to gain access for root therapy. 35. These incisions are made in a horizontal direction and may be coronally or apically directed. Itisnecessary toemphasise thefollowing points: I)Reaming ofthemedullary cavity wasnever employed. Trismus is the inability to open the mouth. - Charter's method - Bass method - Still man method - Both a and b correct . After the patient has been thoroughly evaluated and pre-pared with non-surgical periodontal therapy, quadrant or area to be operated is selected. The flap technique best suited for grafting purposes is the papilla preservation flap because it provides complete coverage of the interdental area after suturing. Incisions can be divided into two types: the horizontal and vertical incisions, Basic incisions used in periodontal surgeries, This internal bevel incision is placed at a distance from the gingival margin, directed towards the alveolar crest. The vertical incision should be made in such a way that interdental papilla is completely preserved. The flap is placed at the toothbone junction by apically displacing the flap. Contents available in the book .. Following is the description of marginal and para-marginal internal bevel incisions.

It allows the vertical incision to be sutured without stretching the flap over the cervical convexity of the tooth. To improve esthetics as well as treat periodontal disease the method of choice remains is undisplaced flap surgery [12, 13]. Hemorrhage occurring after 7-14 days is secondary to trauma or surgery. 2)Wenow employ aK#{252}ntscher-type nailslightly bent forward inits upper part, allowing easier removal when indicated. Contents available in the book .. Journal of periodontology. The area is then irrigated with normal saline and flaps are adapted back in position. After the gingivectomy incision, primary and the secondary incisions are placed in the same way as described in the partial-thickness flap procedure. The internal bevel incision in an undisplaced flap procedure is started at the same point where an external bevel incision is started in agingivectomyprocedure. Irrespective of performing any of the above stated surgical procedures, periodontal wound healing always begins with a blood clot in the space maintained by the closed flap after suturing 36. With some variants, the apically displaced flap technique can be used for (1) pocket eradication and/or (2) widening the zone of attached gingiva. A crescent-shaped incision is sometimes used during the crown lengthening procedure. 19. An intact papilla should be either excluded or included in the flap. It is indicated when the flap has to be positioned apically and when the exposure of the bone is not required. In case, where osseous recontouring is done the flap margins may be re-scalloped and trimmed to adapt to the root bone junction. In non-esthetic areas with moderate to deep pockets and for crown lengthening, this incision is indicated. Conflicting data surround the advisability of uncovering the bone when this is not actually needed. Contents available in the book . Square, parallel, or H design. This is a modification of the partial thickness palatal flap procedure in which gingivectomy is done prior to the placement of primary and the secondary incision. Interrupted or continuous sling sutures are then placed to secure the flaps in their place. Care should be taken to insert the blade in such a way that the papilla is left with a thickness similar to that of the remaining facial flap. The full-thickness mucoperiosteal flap procedure is the same as that described for the buccal and lingual aspects. For the correction of bone morphology (osteoplasty, osseous resection).

Also, complicated or prolonged surgical procedures that require full-thickness mucoperiosteal flaps with resultant edema can lead to trismus. Contents available in the book .. The most abundant cells during the initial healing phase are the neutrophils. Tooth with marked mobility and severe attachment loss. See video of the surgery at: Modified flap operation. Contraindications of periodontal flap surgery. Frenectomy-frenal relocation-vestibuloplasty. In the following discussion, we shall study in detail, the surgical techniques that are followed in various flap procedures. Periodontal flap surgery with conventional incision commonly results in gingival recession and loss of interdental papillae after treatment. The beak-shaped no. In the upcoming chapters, we shall read about various regenerative procedures which are aimed at achieving regeneration of lost periodontal structures. 2. A full-thickness flap is then elevated to expose 1-2 mm of the marginal bone. May cause attachment loss due to surgery. Short anatomic crowns in the anterior region. Fractures of the frontal sinus are a common maxillofacial trauma and constitute 5-15% of all maxillofacial fractures. The area to be operated is then isolated with the help of gauge. This flap procedure is indicated in areas that do not have esthetic concerns and areas where a greater reduction in pocket depth is desired. This is also known as Ledge-and-wedge technique. It is indicated where complete access to the bone is required, for example, in the case of osseous resective surgeries. For regenerative procedures, such as bone grafting and guided tissue regeneration.

The choice of which procedure to use depends on two important anatomic landmarks: the pocket depth and the location of the mucogingival junction. Incisions used in papilla preservation flap using primary and secondary incisions. Periodontal pockets in severe periodontal disease. drg. After the administration of local anesthesia, bone sounding is performed to identify the exact thickness of the gingiva. The incision is usually carried to a point apical to the alveolar crest, depending on the thickness of the tissue. This flap procedure utilizes two incisions referred to as primary and secondary incisions which contain tissue which has to be removed. The main causes for the bleeding include intrinsic trauma to the operated site, even after repeated instructions patients tend to play with the area of surgery with their tongue and dislodge the blood clot, tongue may also cause suction of blood by creating small negative pressures that cause secondary bleeding, presence of foreign bodies, infection, salivary enzymes may lyse the blood clot before it gets organized and slippage of suture. This flap procedure allows complete access to the root surfaces allowing their mechanical debridement and decontamination under direct vision. So, this procedure cannot be employed when modified Widman flap, excisional new attachment procedure and regenerative procedures such as osseous grafting are done because these procedures require primary closure. Possibility of exposure of furcations and roots, which complicates postoperative supragingival plaque control. Apically displaced flaps have the important advantage of preserving the outer portion of the pocket wall and transforming it into attached gingiva. This is also known as. Step 2:The initial or internal bevel incision is made (Figure 59-4) after scalloping the bleeding marks on the gingiva (Figure 59-5). The thicker the tissue is, the more apical the ending point of the incision (see Figure 59-4). Scalloping follows the gingival margin. The most apical end of the internal bevel incision is exposed and visible. in 1985 28 introduced a detailed description of the surgical approach reported earlier by Genon and named the technique as Papilla Preservation Flap. 12 or no. a. Non-displaced flap. 2. 2. Genon and Bender in 1984 27 also reported a similar technique indicated for esthetic purpose. This wedge of tissue contains most of the inflamed and granulomatous areas that constitute the lateral wall of the pocket as well as the junctional epithelium and the connective tissue fibers that still persist between the bottom of the pocket and the crest of the bone. Wood DL, Hoag PM, Donnenfeld OW, Rosenfeld LD. The incision is usually scalloped to maintain gingival morphology and to retain as much papilla as possible. The narrow width of attached gingiva which may further reduce post-operatively. These . The most likely etiologic factor is local anesthetic, secondary to an inferior alveolar nerve block that penetrates the medial pterygoid muscle. After pushing the papillae buccally, both the flap and the papilla are reflected off the bone with a periosteal elevator. With our innovative curriculum and cutting-edge training methods, we are committed to delivering the highest quality of dental education and expertise to our students. Tooth with extremely unfavorable clinical crown/root ratio. Clubbing Tar Staining Signs of other disease Hands warm and well perfused Salbutamol and CO2 retention flap Radial rate and rhythm respiratory rate Pattern of breathing ASK FOR BP FACE Eye . The flaps are then replaced to their original position and sutured using interrupted or continuous sling sutures. 5. Periodontal therapy, flap, periodontal flap, full thickness flap, partial thickness flap, nondisplaced flap, displaced flap, conventional flaps, papilla preservation . Contents available in the book .. It is also known as the mucoperiosteal (mucosal tissue + periosteum) flap. As described in History of surgical periodontal pocket therapy and osseous resective surgeries the palatal approach for . If a full-thickness flap has been elevated, the sutures are placed along the mesial and the distal vertical incision lines to. Step 2: The initial, or internal bevel, incision is made. The following steps outline the undisplaced flap technique: Step 1: The pockets are measured with the periodontal probe. Contents available in the book .. This is a commonly used incision during periodontal flap surgeries. It is the incision from which the flap is reflected to expose the underlying bone and root. Apically displaced flaps have the important advantage of preserving the outer portion of the pocket wall and transforming it into attached gingiva. This drawback of conventional flap techniques led to the development of this flap technique which intended to spare the papilla instead of splitting it. Contents available in the book .. The base of the flap should be wider than the flap margin so that the blood supply to the flap is not jeopardized. In areas with a narrow width of attached gingiva. The main advantages of this procedure are maximum conservation of the keratinized tissue, maximum closure of the flaps and greater access to the underlying bony topography and the distal furcation. Internal bevel and is 0.5-1.0mm from gingival margin Modified Widman Flap 6. This flap procedure causes the greatest probing depth reduction. The present systematic review analysed the clinical outcomes of resective surgery versus access flap procedures in subjects with periodontitis stages II-III (previously termed moderate to advanced periodontitis), in order to support the development of evidence-based guidelines for periodontal therapy. Contents available in the book .. The modified Widman flap has been described for exposing the root surfaces for meticulous instrumentation and for the removal of the pocket lining.6 Again, it is not intended to eliminate or reduce pocket depth, except for the reduction that occurs during healing as a result of tissue shrinkage. It differs from the modified Widman llap in that the soft tissue pocket wall is removed with the initial incision; thus it may be considered an internal bevel glngivectomy. The internal bevel incision should be scalloped into the interdental area to preserve the interdental papilla (see Figure 59-2). Eliminate or reduce pocket depth via resection of the pocket wall, 3. Contents available in the book . HGF is characterized as a benign, slowly progressive, nonhemorrhagic, fibrous enlargement of keratinized gingiva.It can cover teeth in various degrees, and can lead to aesthetic disfigurement. The most apical end of the internal bevel incision is exposed and visible. Contents available in the book .. After this, the second incision or the sulcular incision is made from the bottom of the pocket to the crest of the alveolar bone. Give local anaesthetic for 2 weeks and recall C. Recall for follow up after 6 weeks D. 13- Which is the technique that will anesthetize both hard and soft tissues of the lower posterior teeth region in one injection A. Gow gates***** B. Journal of periodontology. It is contraindicated in areas where the width of attached gingiva would be reduced to < 3 mm. The apically displaced flap is . Conventional flaps include the modified Widman flap, the undisplaced flap, the apically displaced flap, and the flap for reconstructive procedures. Undisplaced flap and apically repositioned flap. Scalloping required for the different types of flaps (see, The apically displaced flap technique is selected for cases that present a minimal amount of keratinized, attached gingiva. During the initial phase of healing, inflammatory cells are attracted by platelet and complement derived mediators and aggregate around the blood clot. Currently, the undisplaced flap may be the most frequently performed type of periodontal surgery. These are indicated in cases where interdental spaces are too narrow and when the flap needs to be displaced. Re-inspection of the operated area is done to check for any deposits on the root surfaces, remaining granulation tissue or tissue tags which are removed, if detected. The continuous sling suture has an advantage that it uses tooth as an anchor and thus, facilitates to hold the flap edges at the root-bone junction. It is caused by trauma or spasm to the muscles of mastication. Thus, an incision should not be made too close to the tooth, because it will not eliminate the pocket wall, and it may result in the re-creation of the soft-tissue pocket. Several techniques can be used for the treatment of periodontal pockets. Full-thickness or partial thickness flap may be elevated depending on the objectives of the surgery. All three flap techniques that were just discussed involve the use of the basic incisions described in Chapter 57: the internal bevel incision, the crevicular incision, and the interdental incision. In case where the soft tissue is quite thick, this incision. 6. Following shapes of the distal wedge have been proposed which are, 1. If detected, they are removed. After the flap has been elevated, a wedge of tissue remains on the teeth and is attached by the base of the papillae. The triangular wedge of the tissue made by the above three incisions is then removed with the help of curettes. Deep intrabony defects. It produces a sharp, thin flap margin for adaptation to the bone-tooth junction. The periosteum left on the bone may also be used for suturing the flap when it is displaced apically. Otherwise, the periodontal dressing may be placed. Contents available in the book .. The buccal and the lingual/palatal flaps are then elevated to expose the diseased root surfaces and the marginal bone. With this access, the surgeon is able to make the third incision, which is also known as the interdental incision, to separate the collar of gingiva that is left around the tooth. This incision is indicated in the following situations. When the flap is returned and sutured in its original position. The periodontal flap is one of the most frequently employed procedures, particularly for moderate and deep pockets in posterior areas (see Chapter 57). It can be used in combination with other procedures such as osseous resection, regenerative procedures, hemisection procedure and procedures involving wedge excision. Flap design for a conventional or traditional flap technique. 2. Tooth with extremely unfavorable clinical crown/root ratio. 12 or no. Flap design for a sulcular incision flap. Expose the area for the performance of regenerative methods. Two basic flap designs are used. 30 Q . Evian et al. This should include the type of flap, the exact location and type of incisions, the management of the underlying bone, and the final closure of the flap and sutures. 12D blade is usually used for this incision. Swelling is another common complication after flap surgery. Vertical incisions increase flap mobility, thus facilitating better access to the operative area. This website is a small attempt to create an easy approach to understand periodontology for the students who are facing difficulties during the graduation and the post-graduation courses in our field. By doing this, the periosteum is cut and it becomes easy to remove the secondary flap from the bone. 3) The insertion of the guide-wire presents This incision can be accomplished only if sufficient attached gingiva remains apical to the incision. The flap is then elevated with the help of a small periosteal elevator. . Coronally displaced flap Connective tissue autograft Free gingival graft Laterally positioned flap Apically displaced flap 5.
