A full-thickness flap is elevated with the help of a periosteal elevator whereas partial-thickness flap is elevated using sharp dissection with a Bard-Parker knife. 3. 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. It can be used in combination with other procedures such as osseous resection, regenerative procedures, hemisection procedure and procedures involving wedge excision. Undisplaced (replaced) flap This type of periodontal flap Apically positions pocket wall and preserves keratinized gingiva by apically positioning Apically displaced (positioned) flap This type of incision is used for what type of flap? Swelling is another common complication after flap surgery. May cause hypersensitivity. Incisions used in papilla preservation flap using primary and secondary incisions. Contents available in the book .. 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. Several techniques can be used for the treatment of periodontal pockets. 2. In non-esthetic areas with moderate to deep pockets and for crown lengthening, this incision is indicated. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. Scalloping follows the gingival margin. It is an access flap for the debridement of the root surfaces. To facilitate the close approximation of the flap, judicious osteoplasty, if required, is performed. According to flap reflection or tissue content: The thicker the tissue is, the more apical the ending point of the incision (see Figure 59-4). 1972 Mar;43(3):141-4. It is contraindicated in the areas where treatment for an osseous defect with the mucogingival problem is not required, in areas with thin periodontal tissue with probable osseous dehiscence or osseous fenestration and in areas where the alveolar bone is thin.

Cadherins B. Adhesins C. Cohesins D. Fimbriae Answer: B 2. 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). 12D blade is usually used for this incision. Most commonly done suturing is the interrupted suturing. The modified Widman flap facilitates instrumentation for root therapy. Fractures of the frontal sinus are a common maxillofacial trauma and constitute 5-15% of all maxillofacial fractures. Contents available in the book .. The periodontal flap surgeries have been practiced for more than one hundred years now, since their introduction in the early 1900s. The triangular wedge of the tissue, hence formed is removed. This flap procedure may be regarded as internal bevel gingivectomy because the first incision or the internal bevel incision given during this procedure is placed at the level of pocket depth (Figure 62.1), thus including all the soft tissue containing and supporting periodontal pocket. 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 base of the flap should be wider than the flap margin so that the blood supply to the flap is not jeopardized. During this whole procedure, the placement of the primary incision is very important because if improperly given it may become short, leaving exposed bone or may become longer requiring further trimming which is difficult. The modified Widman flap facilitates instrumentation for root therapy. Contents available in the book . Within the first few days, monocytes and macrophages start populating the area 37. Mitral facies or malar flush There is a tapping apex beat which is undisplaced. After one week, the sutures are removed and the area is irrigated with normal saline solution. In this flap procedure, all the soft tissue, including the periosteum is reflected to expose the underlying bone. Ahmad Syaify, Sp.Perio (K) Spesialis Konsultan Bedah Perio & Estetik. The book is usually delivered within one week anywhere in India and within three weeks anywhere throughout the world. The thickness of the gingiva. The apically displaced flap technique is selected for cases that present a minimal amount of keratinized, attached gingiva. The following steps outline the undisplaced flap technique: Step 1: The pockets are measured with the periodontal probe. 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. Table 1: showing thickness of gingiva in maxillary tooth region . There have been a lot of modifications and improvisations in various periodontal surgical techniques during this period. It is also known as a partial-thickness flap. The coronally directed incision is designated as external bevel incision whereas the apically directed incisions are the internal bevel and sulcular incision. The necessary degree of access to the underlying bone and root surfaces and the final position of the flap must be considered when designing the flap. Vertical relaxing incisions are usually not needed. b. Papilla preservation flap. Residual periodontal fibers attached to the tooth surface should not be disturbed. In case of periodontitis with active pockets 5-6 mm deep or greater, that do not respond satisfactorily to the initial therapy. 5. Contents available in the book .. What are the steps involved in the Apically Displaced flap technique? Along with removing the tissue above the alveolar crest, this incision also reveals the thickness of the soft tissue. This is essentially an excisional procedure of the gingiva. For the management of the papilla, flaps can be conventional or papilla preservation flaps. Another important objective of periodontal flap surgery is to regenerate the lost periodontal apparatus. Log In or, (Courtesy Dr. Kitetsu Shin, Saitama, Japan. The papillae are then carefully pushed back through the interdental embrasures to palatal or lingual aspect. The modified Widman flap is indicated in cases of perio-dontitis with pocket depths of 5-7 mm. When the flap is placed apically, coronally or laterally to its original position. If the dressing has to be placed, a dry foil is first placed over the flap before covering it with the dressing so that the displacement of the pack under the flap is prevented. Maintaining primary closure after guided bone regeneration procedures: Introduction of a new flap design and preliminary results. - Charter's method - Bass method - Still man method - Both a and b correct . The distance of the incision from the gingival margin (thickness of the incision) varies according to the pocket depth, the thickness of the gingiva, width of the attached gingiva, shape and contour of gingival margins and whether or not the operative area is in the esthetic zone. After the removal of the secondary flap, scaling and root planing is done and the flap is adapted to its position. 2. Trombelli L, Farina R. Flap designs for periodontal healing. 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. For the treatment of periodontal pockets with minimal osseous defects, a procedure without or minimal osseous resection is done, whereas, in case of moderate osseous defects and crown lengthening procedures, osseous resection is done with the flap procedure. When the flap is returned and sutured in its original position. Step 2:The gingiva is reflected with a periosteal elevator (Figure 59-3, D).

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). 1. 6. Expose the area for the performance of regenerative methods. 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. In another technique, vertical incisions and a horizontal incision are placed. Step 2: The initial, or internal bevel, incision is made. As the flap is to be placed in an apical position, vertical incisions are made extending beyond the mucogingival junction. Modified flap operation, This incision is made 1mm to 2mm from the teeth. In this technique no. Some clinicians prefer curettes (Molt 2 curette) or chisels (Ochsenbein No. The challenging nature of scaphoid fracture and nonunion surgery make it an obvious target. 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. One of the most common complication after periodontal flap surgery is post-operative bleeding. The distance of the primary incision from the gingival margin depends on the thickness of the gingiva. 15 or 15C surgical blade is used most often to make this incision. 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 interdental incision is then made to severe the inter-dental fiber attachment. Periodontal pockets in severe periodontal disease. May cause esthetic problems due to root exposure. The incision is then carried out till the line angle of the tooth blending it into the gingival crevice. If the incisions have been made correctly, the flap will be at the crest of the bone with the scalloped papillae positioned interproximally, thus permitting its primary closure. In a full-thickness flap, all of the soft tissue, including the periosteum, is reflected to expose the underlying bone. 3. Contents available in the book .

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. The starting point on the gingiva is determined by whether the flap is apically displaced or not displaced (Figure 57-7). Journal of periodontology. Conventional flaps include the. This flap procedure utilizes two incisions referred to as primary and secondary incisions which contain tissue which has to be removed. Contents available in the book . 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 flaps are then replaced to their original position and sutured using interrupted or continuous sling sutures. Frenectomy-frenal relocation-vestibuloplasty. Flap design for a sulcular incision flap. 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. It protects the interdental papilla adjacent to the surgical site. The area is then irrigated with an antimicrobial solution. 2) by pushing the instrument in the interdental area and twisting it to remove the infected granulomatous tissue. The original intent of the surgery was to access the root surface for scaling and root planing. Areas where greater probing depth reduction is required. However, there are important variations in the way these incisions are performed for the different types of flaps (Figures 59-1 and 59-2). Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. One technique includes semilunar incisions which are . The area is then debrided for all the granulation tissue present and scaling and root planing of the root surfaces are carried out. Conventional flaps include the modified Widman flap, the undisplaced flap, the apically displaced flap, and the flap for reconstructive procedures. To overcome the problem of recession, papilla preservation flap design is used in these areas. Following shapes of the distal wedge have been proposed which are, 1. The incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. A periosteal elevator is inserted into the initial internal bevel incision, and the flap is separated from the bone. Contents available in the book .. 4. After removing the wedge of the tissue the margins of the flap are undermined with the help of scalpel blades . 2011 Sep;25(1):4-15. 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. The initial or the first incision is the internal bevel incision given not more than 1 mm from the crest of the gingiva and directed to the crest of the bone. Undisplaced flap and apically repositioned flap. Contents available in the book .. A vertical incision may be given unilaterally (at one end of the flap) or bilaterally (on both ends of the flap). This is mainly because of the reason that all the lateral blood supply to . The design of the flap is dictated by the surgical judgment of the operator, and it may depend on the objectives of the procedure. Tooth with marked mobility and severe attachment loss.

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. To perform this technique without creating a mucogingival problem, the clinician should determine that enough attached gingiva will remain after removal of the pocket wall. Otherwise, the periodontal dressing may be placed. Periodontal pockets in areas where esthetics is critical. 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. 1. Palatal flaps cannot be displaced because of the absence of unattached gingiva. Flaps are used for pocket therapy to accomplish the following: 1. 6. 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 secondary. Crown lengthening procedures to expose restoration margins. The process of healing progresses through various phases of . Tooth with extremely unfavorable clinical crown/root ratio. Conventional flaps include: The modified Widman flap, The undisplaced flap, The apically displaced flap, The flap for regenerative procedures. The beak-shaped no. Papilla Preservation Flaps :it incorporates the entire papilla in one of the flap by means of crevicular interdental incison to sever the connective tissue attachment & a horizontal incision at the base . The partial-thickness flap includes only the epithelium and a layer of the underlying connective tissue. The buccal and palatal/lingual flaps are reflected with the help of a periosteal elevator. Step 5:Tissue tags and granulation tissue are removed with a curette.

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. 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. 15 scalpel blade is used to make a triangular incision distal to the molar on retromolar pad area or the maxillary tuberosity. This incision is placed through the gingival sulcus. 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%). The incision is usually started at the disto-palatal line angle of the last molar and continued forward using a scalloped, inverse-beveled, partial-thickness incision to create a thin partial-thickness flap. Flap adaptation is then done with the help of moistened gauze and any excess blood is expressed. Posterior spinal fusion for adolescent idiopathic scoliosis using a convex pedicle screw technique; . Sulcular incision is now made around the tooth to facilitate flap elevation. Following are the steps followed during this procedure. It is indicated when the flap has to be positioned apically and when the exposure of the bone is not required. Minimally invasive techniques have recently been described for the reduction of the isolated anterior frontal sinus fracture via a closed approach. 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. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. In other words, we can say that. This will allow the clinician to retain the maximum amount of gingival tissue, including the papilla, which is essential for graft or membrane coverage. 19. 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). FLAP PERIODONTAL. It is indicated where complete access to the bone is required, for example, in the case of osseous resective surgeries. It is also known as the mucoperiosteal (mucosal tissue + periosteum) flap. The incision is usually scalloped to maintain gingival morphology and to retain as much papilla as possible. Flap design for a conventional or traditional flap technique. As already discussed in, History of surgical periodontal pocket therapy and osseous resective surgeries the original Widman flap was presented to the Scandinavian Dental Association in 1916 by Leonard Widman which was later published in 1918. Following is the description of step by step procedure followed while doing a modified Widman flap surgery. 5. 4. A detailed description of the historical aspect of various flap surgeries has been given in the previous chapter. Chlorhexidine rinse 0.2% bid . (adsbygoogle = window.adsbygoogle || []).push({}); The external bevel incision is typically used in gingivectomy procedures. See video of the surgery at: Modified flap operation. Before we go into the details of the periodontal flap surgeries, let us discuss the incisions used in surgical periodontal therapy. These, Historically, gingivectomy was the treatment of choice for these areas until 1966, when Robinson 32 addressed this problem and gave a separate surgical procedure for these areas which he termed, The triangular wedge technique is used in cases where the adequate zone of attached gingiva is present and in cases of short or small tuberosity. Bone architecture is not corrected unless it prevents good tissue adaptation to the necks of the teeth. In this technique no. Root planing is done followed by osseous surgery if needed. The blood clot provides a framework for the proliferation and migration of cells from surrounding tissues including gingiva, periodontal ligament (PDL), cementum, and alveolar bone 38. The internal beveled incision for the modified Widman flap closely follows the scalloped outline of the dentition to minimize the loss of the attached keratinized gingiva. 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. A new technique for arthroscopic meniscectomy using a traction suture, , 2015-02, ()KCI . 6. Contents available in the book .. The undisplaced flap and gingivectomy are the two techniques that surgically removed the pocket wall. May cause attachment loss due to surgery. 2)Wenow employ aK#{252}ntscher-type nailslightly bent forward inits upper part, allowing easier removal when indicated. Coronally displaced flap.

One incision is now placed perpendicular to these parallel incisions at their distal end. This preview shows page 166 - 168 out of 197 pages.. View full document. 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. After these three incisions are made correctly, a triangular wedge of the tissue is obtained containing the inflamed connective. Coronally displaced flap Connective tissue autograft Free gingival graft Laterally positioned flap Apically displaced flap 5. During the initial phase of healing, inflammatory cells are attracted by platelet and complement derived mediators and aggregate around the blood clot. The granulomatous tissue is then removed and the deposits on the root surfaces are removed by scaling. Increase accessibility to root deposits for scaling and root planing, 2. A periodontal flap is a section of gingiva and/or mucosa surgically separated from the underlying tissue to provide visibility and access to the bone and root surfaces 1. Periodontal maintenance (Supportive periodontal therapy), Orthodontic-periodontal interrelationship, Piezosurgery in periodontics and oral implantology. Step 6:Bone architecture is not corrected unless it prevents good tissue adaptation to the necks of the teeth. The palatal flap offers a technically simple and predictable option for intraoral reconstruction. The area to be operated is then isolated with the help of gauge. 6. Genon and Bender in 1984 27 also reported a similar technique indicated for esthetic purpose.
