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. The flaps may be thinned to allow for close adaptation of the gingiva around the entire circumference of the tooth and to each other interproximally. These meniscus tears are displaced into the tibia or femoral recesses and can be often difficult to diagnose intraoperatively. This flap procedure causes the greatest probing depth reduction. The main disadvantage of this procedure is that healing in the interdental areas takes place by secondary intention. The interdental incision is then given to remove the wedge of tissue that contains the pocket wall. The following statements can be made regarding periodontal regeneration procedures. in 1985 28 introduced a detailed description of the surgical approach reported earlier by Genon and named the technique as Papilla Preservation Flap. Conflicting data surround the advisability of uncovering the bone when this is not actually needed. The beak-shaped no. This will allow better coverage of the bone at both the radicular and interdental areas. 6. Journal of periodontology. Conventional flaps include: The modified Widman flap, The undisplaced flap, The apically displaced flap, The flap for regenerative procedures. The flap is then elevated with the help of a small periosteal elevator. The first step . Flap design for a sulcular incision flap. Diagram showing the location of two different areas where the internal bevel incision is made in an undisplaced flap. Minimally invasive techniques have recently been described for the reduction of the isolated anterior frontal sinus fracture via a closed approach. Contents available in the book . The Orban knife is usually used for this incision. Sutures are removed after one week and the area is irrigated with normal saline. May cause hypersensitivity. As described in History of surgical periodontal pocket therapy and osseous resective surgeries the palatal approach for . In areas with a narrow width of attached gingiva. (adsbygoogle = window.adsbygoogle || []).push({}); The external bevel incision is typically used in gingivectomy procedures. 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. However, there are important variations in the way these incisions are performed for the different types of flaps (Figures 59-1 and 59-2). This incision, together will the para-marginal internal bevel incision, forms a V-shaped wedge ending at or near the crest of bone, containing most of the inflamed and . The periodontal flap is one of the most frequently employed procedures, particularly for moderate and deep pockets in posterior areas (see, Increase accessibility to root deposits for scaling and root planing, Eliminate or reduce pocket depth via resection of the pocket wall, Gain access for osseous resective surgery, if necessary, Expose the area for the performance of regenerative methods, Technique for Access and Pocket Depth Reduction or Elimination, All three flap techniques that were just discussed involve the use of the basic incisions described in. The incision is made at the level of the pocket to discard the tissue coronal to the pocket if there is sufficient remaining attached gingiva. Apically displaced flaps have the important advantage of preserving the outer portion of the pocket wall and transforming it into attached gingiva. This is especially important in maxillary and mandibular anterior areas which have a prime esthetic concern.

The partial-thickness flap may be necessary when the crestal bone margin is thin and exposed with an apically placed flap or when dehiscences or fenestrations are present. A. A detailed description of the historical aspect of various flap surgeries has been given in the previous chapter. Periodontal pockets in severe periodontal disease. Contents available in the book . Within the first few days, monocytes and macrophages start populating the area, Post-operative complications after periodontal flap surgery, Hemorrhage occurring after 7-14 days is secondary to trauma or surgery. A Technique to Obtain Primary Intention Healing in Pocket Elimination Adjacent to an Edentulous Area Article Jan 1964 G. Kramer M. Schwarz View Mucogingival Surgery: The Apically Repositioned. After the flap is reflected, a third incision is made in the interdental spaces coronal to the bone with a curette or an interproximal knife, and the gingival collar is removed (, Tissue tags and granulation tissue are removed with a curette. 19. 2. Once the interdental papilla is mobile, a blunt instrument is used to carefully push the interdental papilla through the embrasure. Periodontal flaps can be classified on the basis of the following: For bone exposure after reflection, the flaps are classified as either full-thickness (mucoperiosteal) or partial-thickness (mucosal) flaps (Figure 57-1). The incision is usually scalloped to maintain gingival morphology and to retain as much papilla as possible. Step 1:The initial incision is an internal bevel incision to the alveolar crest starting 0.5mm to 1mm away from the gingival margin (Figure 59-3, C). Long-term outcome of undisplaced fatigue fractures of the femoral neck in young male adults; Several techniques such as gingivectomy, undisplaced flap with or without osseous surgery, apically repositioned flap . The square, 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. Deep intrabony defects. Genon and Bender in 1984 27 also reported a similar technique indicated for esthetic purpose. Contents available in the book .. After the administration of local anesthesia, bone sounding is performed to identify the exact thickness of the gingiva. Therefore, the two anatomic landmarksthe pocket depth and the location of the mucogingival junctionmust be considered to evaluate the amount of attached gingiva that will remain after the surgery has been completed. Step 2:The gingiva is reflected with a periosteal elevator (Figure 59-3, D). Sixth day: (10 am-6pm); "Perio-restorative surgery" Periodontal pockets in areas where esthetics is critical. News & Perspective Drugs & Diseases CME & Education The coronally directed incision is designated as external bevel incision whereas the apically directed incisions are the internal bevel and sulcular incision. Two types of horizontal incisions have been recommended: the internal bevel incision,6 which starts at a distance from the gingival margin and which is aimed at the bone crest, and the crevicular incision, which starts at the bottom of the pocket and which is directed to the bone margin. What is a periodontal flap? The challenging nature of scaphoid fracture and nonunion surgery make it an obvious target. 2014 Apr;41:S98-107. Before we go into the details of the periodontal flap surgeries, let us discuss the incisions used in surgical periodontal therapy. By doing this, the periosteum is cut and it becomes easy to remove the secondary flap from the bone. With this access, the surgeon is able to make the. The incisions given are the same as in case of modified Widman flap procedure. This is mainly because of the reason that all the lateral blood supply to . Contents available in the book .. After administration of local anesthesia, bone sounding is done to assess the thickness of gingiva and underlying osseous topography. Periodontal pockets in severe periodontal disease. The incision is carried around the entire tooth. 6. in adults. Tooth with marked mobility and severe attachment loss. With the conventional flap, the interdental papilla is split beneath the contact point of the two approximating teeth to allow for the reflection of the buccal and lingual flaps. 5. Several techniques such as gingivectomy, undisplaced flap with or without osseous surgery, apically repositioned flap with or without resective osseous surgery, and orthodontic forced eruption with or without fibrotomy have been proposed for clinical crown lengthening. Henry H. Takei, Fermin A. Carranza and Kitetsu Shin. The bleeding is frequently associated with pain. The most abundant cells during the initial healing phase are the neutrophils. With some variants, the apically displaced flap technique can be used for (1) pocket eradication and/or (2) widening the zone of attached gingiva. The internal bevel incision should be scalloped into the interdental area to preserve the interdental papilla (see Figure 59-2). Modified Widman flap, The proper placement of the flap margin at the toothbone junction during closure is important to prevent either recurrence of the pocket or the exposure of bone. Areas where greater probing depth reduction is required. This complete exposure of and access to the underlying bone is indicated when resective osseous surgery is contemplated. The area is then debrided for all the granulation tissue present and scaling and root planing of the root surfaces are carried out. 1. The secondary incision is given from the depth of the periodontal pocket till the alveolar crest. Persistent inflammation in areas with moderate to deep pockets. Contents available in the book .. Pronounced gingival overgrowth, which is handled more efficiently by means of gingivectomy / gingivoplasty. An intact papilla should be either excluded or included in the flap. The blade should be kept on the vertical height of the alveolus so that palatal artery is not injured. Unrealistic patient expectations or desires. Contents available in the book .. Areas where greater probing depth reduction is required. Severe hypersensitivity. Currently, the undisplaced flap may be the most frequently performed type of periodontal surgery. 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. Areas which do not have an esthetic concern. After suturing, the flap is adapted around the neck of the teeth with the help of moistened gauze. This suturing causes the apical positioning of the facial papilla, thus creating open gingival embrasures (black holes). The papillae are then carefully pushed back through the interdental embrasures to palatal or lingual aspect. . Frenectomy-frenal relocation-vestibuloplasty. Minor osseous recontouring may be done and the flap is then adapted into the interdental areas. Unsuitable for treatment of deep periodontal pockets. In this technique, two incisions are made with the help of no. 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. This incision is placed through the gingival sulcus. Along with removing the tissue above the alveolar crest, this incision also reveals the thickness of the soft tissue. It is indicated where complete access to the bone is required, for example, in the case of osseous resective surgeries. Furthermore, the access to the bone defects facilitates the execution of various regenerative procedures. 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: When bone is stripped of its periosteum, a loss of marginal bone occurs, and this loss is prevented when the periosteum is left on the bone.4 Although this is usually not clinically significant,7 the differences may be significant in some cases (Figure 57-2). The choice of which procedure to use depends on two important anatomic landmarks: the pocket depth and the location of the mucogingival junction.
