Minimally invasive techniques have recently been described for the reduction of the isolated anterior frontal sinus fracture via a closed approach. Fundamental principles in periodontal plastic surgery and mucosal augmentationa narrative review. The following steps outline the undisplaced flap technique: Step 1: The pockets are measured with the periodontal probe. This incision is placed through the gingival sulcus. Contents available in the book . Clin Appl Thromb Hemost. 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. . 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 It is discarded after the crevicular (second) and interdental (third) incisions are performed (Figure 57-5). The periodontal flap is one of the most frequently employed procedures, particularly for moderate and deep pockets in posterior areas (see Chapter 57). Normal interincisal opening is approximately 35-45mm, with mild, Periobasics A Textbook of Periodontics and Implantology, Text Book of Basic Sciences for MDS Students, History of surgical periodontal pocket therapy and osseous resective surgeries. After one week, the sutures are removed and the area is irrigated with normal saline solution. In another technique, vertical incisions and a horizontal incision are placed. This flap procedure is indicated in areas that do not have esthetic concerns and areas where a greater reduction in pocket depth is desired. 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. If extensive osseous recontouring is planned, an exaggerated incision is given. Evian et al. It is also known as a partial-thickness flap. Tooth with marked mobility and severe attachment loss.

The internal bevel incision is basic to most periodontal flap procedures. Contents available in the book .. Unsuitable for treatment of deep periodontal pockets. The esthetic and functional demands of maxillofacial reconstruction have driven the evolution of an array of options. According to management of papilla: Contents available in the book . After removing the wedge of the tissue the margins of the flap are undermined with the help of scalpel blades, In this technique, two incisions are made with the help of no. After administration of local anesthesia, bone sounding is done to assess the thickness of gingiva and underlying osseous topography. The most abundant cells during the initial healing phase are the neutrophils. Papillae are then sutured with interrupted or horizontal mattress sutures. The reasons for placing vertical incisions at line angles of the teeth are. After the area to be operated is irrigated with an anti-microbial solution, local anesthesia is applied and the area is isolated after profound anesthesia has been achieved. Contents available in the book .. The most abundant cells during the initial healing phase are the neutrophils. The Orban knife is usually used for this incision. 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. 2)Wenow employ aK#{252}ntscher-type nailslightly bent forward inits upper part, allowing easier removal when indicated.

Tooth with marked mobility and severe attachment loss. Sutures are placed to secure the flaps in their position. The beak-shaped no. . 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. Connective tissue grafting harvesting techniques as well as free gingival graft. 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 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. This flap procedure utilizes two incisions referred to as primary and secondary incisions which contain tissue which has to be removed. Incisions can be divided into two types: the horizontal and vertical incisions 7. Table 1: showing thickness of gingiva in maxillary tooth region . Periodontal pockets in severe periodontal disease. Contents available in the book . It is the incision from which the flap is reflected to expose the underlying bone and root. Unrealistic patient expectations or desires. Itisnecessary toemphasise thefollowing points: I)Reaming ofthemedullary cavity wasnever employed. Another important objective of periodontal flap surgery is to regenerate the lost periodontal apparatus. After healing, the resultant architecture of the area should enhance the ease and effectiveness of self-performed oral hygiene measures by the patient. 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 initial or internal bevel incision is made (. In the following discussion, we shall study in detail, the surgical techniques that are followed in various flap procedures. This flap procedure causes the greatest probing depth reduction. These . Step 2:The initial or internal bevel incision is made (Figure 59-4) after scalloping the bleeding marks on the gingiva (Figure 59-5). An electronic search without time or language restrictions was . a. Locations of the internal bevel incisions for the different types of flaps. 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. The deposits on the root surfaces are removed and root planing is done. The incision is carried around the entire tooth. This will allow the clinician to retain the maximum amount of gingival tissue, including the papilla, which is essential for graft or membrane coverage. Contents available in the book . Conflicting data surround the advisability of uncovering the bone when this is not actually needed. Contents available in the book .. 19. Internal bevel and is 0.5-1.0mm from gingival margin Modified Widman Flap The periodontal dressing is not required if the flap has been adapted adequately to cover the interdental area. Although some details may be modified during the actual performance of the procedure, detailed planning allows for a better clinical result. According to flap reflection or tissue content: C. According to flap placement after surgery: Diagram showing full-thickness and partial-thickness flap. Square, parallel, or H design. May cause esthetic problems due to root exposure. 15 scalpel blade, parallel to each other beginning at the distal end of the edentulous area, continued to the tooth. DESCRIPTION. This incision causes extensive loss of tissue and is indicated only in cases of gingival overgrowth. A full-thickness flap is then elevated to expose 1-2 mm of the marginal bone. Clinical crown lengthening in multiple teeth. 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. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. Access flap for guided tissue regeneration. Pockets around the teeth in which a complete removal of root irritants is not clinically possible without gaining complete access to the root surfaces. 1. 2011 Sep;25(1):4-15. Contents available in the book .. Following is the description of these flaps. Clinical crown lengthening in multiple teeth. A. 2. These techniques are described in detail in Chapter 59. Contents available in the book . 15 scalpel blade is used to make a triangular incision distal to the molar on retromolar pad area or the maxillary tuberosity. Figure 2:The graph represents the distribution of various The buccal and the lingual/palatal flaps are then elevated to expose the diseased root surfaces and the marginal bone. In addition, the interdental incision is performed after the flap is elevated to remove the interdental tissue. The area is then irrigated with an antimicrobial solution. Enter the email address you signed up with and we'll email you a reset link. 1. Undisplaced flaps are one of the most common periodontal surgeries for correcting anatomical factors that predispose patients to predisposing periodontal disease, and makes it possible to improve aesthetics by eliminating obstacle of wearing a denture. 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. The granulomatous tissue is then removed and the deposits on the root surfaces are removed by scaling. The granulation tissue is removed from the area and scaling and root planing is done. Swelling is another common complication after flap surgery. 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 . 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. 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. As discussed in, Periodontal treatment of medically compromised patients, antibiotic prophylaxis is must in patients with medical conditions such as rheumatic heart disease. 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 distance of the primary incision from the gingival margin depends on the thickness of the gingiva. 2006 Aug;77(8):1452-7. Tooth with extremely unfavorable clinical crown/root ratio. Position of the knife to perform the crevicular (second) incision. Smaller incisions usually cause less postoperative swelling and pain as compared to larger incisions. Incisions used in papilla preservation flap using primary, secondary and tertiary incisions. . Contents available in the book .. Conventional flaps include the modified Widman flap, the undisplaced flap, the apically displaced flap, and the flap for reconstructive procedures. Now, after the completion of the partial-thickness flap, the scalpel blade is directed from the base of this incision towards the bone to give a scoring incision. Contents available in the book .. The beak-shaped no. The full-thickness mucoperiosteal flap procedure is the same as that described for the buccal and lingual aspects. 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. After pushing the papillae buccally, both the flap and the papilla are reflected off the bone with a periosteal elevator. In this technique, two incisions are made with the help of no. 2) by pushing the instrument in the interdental area and twisting it to remove the infected granulomatous tissue. 16: 199-203 . Osseous surgical procedures with very deep osseous defects and irregular bone loss, facially and lingually/ palatally. Hemorrhage occurring after 7-14 days is secondary to trauma or surgery. Contents available in the book .. After debridement, flaps are closely adapted around the teeth in close approximation, allowing healing by primary intention. Following is the description of step by step procedure followed while doing a modified Widman flap surgery. It is most commonly caused due to infection and sloughing of blood vessels. 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. 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. When the flap is returned and sutured in its original position. It is caused by trauma or spasm to the muscles of mastication. Henry H. Takei, Fermin A. Carranza and Jonathan H. Do. 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 mainly because of the reason that all the lateral blood supply to . 74. The patient is then recalled for suture removal after one week. To facilitate the close approximation of the flap, judicious osteoplasty, if required, is performed. One incision is now placed perpendicular to these parallel incisions at their distal end. Contents available in the book .. Different Flap techniques for treatment of gingival recession (Lateral-coronal-double papilla-semilunar-tunnel-apical). Sulcular incision is now made around the tooth to facilitate flap elevation. Periodontal flap surgery with conventional incision commonly results in gingival recession and loss of interdental papillae after treatment. These incisions are made in a horizontal direction and may be coronally or apically directed. Contents available in the book .. The no. Laparoscopic technique for secondary vaginoplasty in male to female transsexuals using a modified . These meniscus tears are displaced into the tibia or femoral recesses and can be often difficult to diagnose intraoperatively. If detected, they are removed. Step 4: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 (Figure 59-3, E and F). 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. Our main aim of doing so is to get complete access to the root surfaces of the teeth and bone defects around the teeth. Platelets rich fibrin (PRF) preparation and application in the . Deep intrabony defects. 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. According to flap reflection or tissue content: Contents available in the book .. Following is the description of marginal and para-marginal internal bevel incisions. Patients at high risk for caries. (1995, 1999) 29, 30 described . During the initial phase of healing, inflammatory cells are attracted by platelet and complement derived mediators and aggregate around the blood clot. The area is anesthetized and bone sounding is done to evaluate the osseous topography, pocket depth, and thickness of the gingiva. Areas where greater probing depth reduction is required. 1. The incision is usually carried to a point apical to the alveolar crest, depending on the thickness of the tissue. A crescent-shaped incision is sometimes used during the crown lengthening procedure.
