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. With some variants, the apically displaced flap technique can be used for (1) pocket eradication and/or (2) widening the zone of attached gingiva. After it is removed there is minimum bleeding from the flaps as well as the exposed bone. . 30 Q . The process of healing progresses through various phases of . Areas which do not have an esthetic concern. Contents available in the book .. The interdental papilla is then freed from the underlying bone and is completely mobilized. The internal bevel incision is basic to most periodontal flap procedures. Local anesthesia is administered to achieve profound anes-thesia in the area to be operated. 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: PDF Clinical crown lengthening: A case report - Oral Journal This type of flap is also called the split-thickness flap. After this, the second or the sulcular incision is made from the bottom of the pocket till the crest of the alveolar bone. Minor osseous recontouring may be done and the flap is then adapted into the interdental areas. Undisplaced flap and apically repositioned flap. The local anesthetic agent is delivered to achieve profound anesthesia. ), Only gold members can continue reading. Conventional surgical approaches include the coronal flap, direct cutaneous incision, and endoscopic techniques. 2. Root planing is done followed by osseous surgery if needed. Following shapes of the distal wedge have been proposed which are, 1. The vertical incisions are made from the center of palatal/lingual surfaces of teeth extending palatally/lingually. Contents available in the book .. It is caused by trauma or spasm to the muscles of mastication. An interdental (third) incision along the horizontal lines seen in the interdental spaces will sever these connections. Myocardial infarction / stroke within 6 months. The primary incision is placed at the outer margin of the gingivectomy incision starting at the disto-palatal line angle of the last molar and continued forward. 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 . In the present discussion, we discussed various flap procedures that are used to achieve these goals. 1. Periodontal flap - SlideShare These vertical incisions are now joined with a horizontal incision as shown in the following figure. Contents available in the book .. The secondary flap removed, can be used as an autogenous connective tissue graft. After the flap has been elevated, a wedge of tissue remains on the teeth and is attached by the base of the papillae. 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. This drawback of conventional flap techniques led to the development of this flap technique which intended to spare the papilla instead of splitting it. In areas with shallow periodontal pocket depth. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. There is no need to determine where the bottom of the pocket is in relation to the incision for the apically displaced flap as one would for the undisplaced flap. Contents available in the book .. 6. That portion of the gingiva left around the tooth contains the epithelium of the pocket lining and the adjacent granulomatous tissue. Contents available in the book .

Contents available in the book .. Conventional flaps include the. The undisplaced flap and gingivectomy are the two techniques that surgically removed the pocket wall. 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). The intrasulcular incision is given using No. The area is anesthetized and bone sounding is done to evaluate the osseous topography, pocket depth, and thickness of the gingiva. Click this link to watch video of the surgery: Areas where greater probing depth reduction is required.

Fugazzotto PA. A new technique for arthroscopic meniscectomy using a traction suture, , 2015-02, ()KCI . PDF Rayast D et al. Localized inflammatory gingival enlar gement - IJRHAS Periodontal pockets in areas where esthetics is critical. 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. 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. Ramfjord and Nissle 8 in 1974, modified the original Widman flap procedure . Japanese Abstracts | Bone & Joint ious techniques such as gingivectomy, undisplaced flap with/without bone surgery, apical resected flap with/without bone resection, and forced eruption with/without fiberotomy have been proposed for crown lengthening procedures.2-4 Selecting the technique depends on various factors like esthetics, crown-to-root ratio, root morphology, furcation 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. The crevicular incision is then placed from the bottom of the pocket till the alveolar crest. Contents available in the book . 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. Papillae are then sutured with interrupted or horizontal mattress sutures. Continuous, independent sling sutures are placed in both the facial and palatal areas (. Vertical relaxing incisions are usually not needed. Suturing is then done using a continuous sling suture. Long-term outcome of undisplaced fatigue fractures of the femoral neck in young male adults; Contents available in the book . As already stated, this technique is utilized when thicker gingiva is present. In the present discussion, we shall study in detail, the current concepts and advances in various periodontal flap surgeries. Conventional flap. Sixth day: (10 am-6pm); "Perio-restorative surgery" May cause attachment loss due to surgery. Wood DL, Hoag PM, Donnenfeld OW, Rosenfeld LD. Displaced flap: The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. The incision is made. Sulcular incision is now made around the tooth to facilitate flap elevation. Contents available in the book .. Contents available in the book . (The use of this technique in palatal areas is considered in the discussion that follows this list. Log In or, (Courtesy Dr. Kitetsu Shin, Saitama, Japan. Moreover, the palatal island flap is the only available flap that can provide keratinized mucosa for defect reconstruction. The flap was repositioned and sutured and . 1. A. Dentocrates The partial-thickness flap is indicated when the flap is to be positioned apically or when the operator does not want to expose bone. Every effort is made to adapt the facial and lingual interproximal tissue adjacent to each other in such a way that no interproximal bone remains exposed at the time of suturing. Laparoscopic technique for secondary vaginoplasty in male to female transsexuals using a modified . In areas with thin gingiva and alveolar process. When the flap is returned and sutured in its original position. Contents available in the book .. Once the bone sounding has been done and the thickness of the gingiva has been established, the design of the flap is decided. The surgical approaches that split the papilla cause shrinkage and decrease in the height of the interdental papilla leading to the exposure of interproximal embrasures. Contents available in the book . The granulation tissue, as well as tissue tags, are then removed. Step 5:Tissue tags and granulation tissue are removed with a curette. The thicker the tissue is, the more apical the ending point of the incision (see Figure 59-4). The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. Areas where greater probing depth reduction is required. 2. Conflicting data surround the advisability of uncovering the bone when this is not actually needed. PDF Prevalence of Age and Gender With Different Flap Techniques Used in The blade is introduced into the sulcus or pocket and is inserted as far as possible into the interdental space around the tooth, keeping it close to the crown. The root surfaces are checked and then scaled and planed, if needed (. However, to do so, the attached gingiva must be totally separated from the underlying bone, thereby enabling the unattached portion of the gingiva to be movable. The incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. In the upcoming chapters, we shall read about various regenerative procedures which are aimed at achieving regeneration of lost periodontal structures. 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 flap is placed at the toothbone junction by apically displacing the flap. 1. It is better to graft an infrabony defect than not grafting. The incisions given are the same as in case of modified Widman flap procedure. It protects the interdental papilla adjacent to the surgical site. Apically displaced flap can be done with or without osseous resection. The interdental incision is then given to remove the wedge of tissue that contains the pocket wall. Trombelli L, Farina R. Flap designs for periodontal healing. Alveolar crest reduction following full and partial thickness flaps. The main objective of periodontal flap surgical procedures is to allow access for the cleaning of the roots of teeth and the removal of the periodontal pocket lining, as well as to treat the irregularities of the alveolar bone, so that when gingiva is repositioned around the teeth, it will allow for the reduction of pockets, infections, and inflammation. See Page 1 7. 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.

A. 1 to 2 mm from the free gingival margin modifed Widman flap or just Position of the knife to perform the crevicular (second) incision. 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. Severe hypersensitivity. Contents available in the book ..
