Contents available in the book .. The pockets are then measured and bleeding points are produced with the help of a periodontal probe on the outer surface of the gingiva, indicating the bottom of the pocket. - Undisplaced flap - Apicaliy displaced flap - All of the above - Modified Widman flap. The apically displaced flap technique is selected for cases that present a minimal amount of keratinized, attached gingiva. The area is then debrided for all the granulation tissue present and scaling and root planing of the root surfaces are carried out. It conserves the relatively uninvolved outer surface of the gingiva. 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. 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%). Areas with sufficient band of attached gingiva. Contents available in the book . a. Bone architecture is not corrected unless it prevents good tissue adaptation to the necks of the teeth. Some clinicians prefer curettes (Molt 2 curette) or chisels (Ochsenbein No. In this technique no. More is the thickness of the gingiva, farther is the incision placed to include more tissue which needs to be removed. Periodontal flaps involve the use of horizontal (mesialdistal) and vertical (occlusalapical) incisions. Trochleoplasty with a flexible osteochondral flap; The role of the width of the forefoot in the development of Morton's neuroma; February. Inferior alveolar nerve block C. PSA 14- A patient comes with . 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. b.

Also, complicated or prolonged surgical procedures that require full-thickness mucoperiosteal flaps with resultant edema can lead to trismus. Takei et al. Tooth with marked mobility and severe attachment loss. 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 buccal and palatal/lingual flaps are reflected with the help of a periosteal elevator. Contents available in the book .. Contents available in the book .. Contents available in the book .. The blade is pushed into the sulcus till resistance is felt from the crestal bone crest. 3. Sutures are placed to secure the flaps in their position. 5. The modified Widman flap. 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. 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. 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). Periodontal pockets in areas where esthetics is critical. In case of periodontitis with active pockets 5-6 mm deep or greater, that do not respond satisfactorily to the initial therapy. 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. To improve esthetics as well as treat periodontal disease the method of choice remains is undisplaced flap surgery [12, 13]. 30 Q . 2)Wenow employ aK#{252}ntscher-type nailslightly bent forward inits upper part, allowing easier removal when indicated. Several techniques such as gingivectomy, undisplaced flap with or without osseous surgery, apically repositioned flap . If a full-thickness flap has been elevated, the sutures are placed along the mesial and the distal vertical incision lines to. In a full-thickness flap, all of the soft tissue, including the periosteum, is reflected to expose the underlying bone. 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: Contents available in the book .. 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. Contents available in the book .. In areas with shallow periodontal pocket depth. 2014 Apr;41:S98-107. Step 3: Crevicular incision is made from the bottom of the . The incision is carried around the entire tooth. Contents available in the book .. The most apical end of the internal bevel incision is exposed and visible. The flaps are then apically positioned to just cover the alveolar crest. Short anatomic crowns in the anterior region. The beak-shaped no. Which of the following mucogingival surgical techniques is indicated in areas of narrow gingival recession adjacent to a wide band of attached gingiva that can be used as a donor site? free gingival autograft double papilla flap modified Widman flap laterally displaced (positioned . Contents available in the book .. This is mainly because of the reason that all the lateral blood supply to . The thickness of the gingiva. Contents available in the book .. If the surgeon contemplates osseous surgery, the first incision should be placed in such a way to compensate for the removal of the bone tissue so that the flap can be placed at the toothbone junction. The reduction of bacterial load and inflammation minimizes further loss of tooth-supporting structures and thus aid in the better prognosis of teeth, provided, the patient stays on a strict maintenance schedule. 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. Signs and symptoms may include continuous flow, oozing or expectoration of blood or copious pink saliva. 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. It is most commonly caused due to infection and sloughing of blood vessels. 12 blade on both the buccal and the lingual/palatal aspects continuing it interdentally extending it in the mesial and distal direction. 15 or 15C surgical blade is used most often to make this incision. 6. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. Which is the best method of brushing technique preferred for the patient with orthodontic appliance: ? The entire surgical procedure should be planned in every detail before the procedure is initiated. To overcome the problem of recession, papilla preservation flap design is used in these areas. In this flap, only epithelium and the underlying connective tissue are reflected, leaving the periosteum intact. Undisplaced femoral neck fractures in children have a high risk of secondary displacement. Itisnecessary toemphasise thefollowing points: I)Reaming ofthemedullary cavity wasnever employed. The undisplaced flap and gingivectomy are the two techniques that surgically removed the pocket wall. The following outline of this technique: Position of the knife to perform the crevicular (second) incision. Contents available in the book . Signs and symptoms may include continuous flow, oozing or expectoration of blood or copious pink saliva. UNDISPLACEDFLAP |Also known as internal bevel gingivectomy |Differs from the modified widman flap inthat pocket wall is removed with the initial incision TECHNIQUE |Pockets are measured with a pocket marker & a bleeding point is created THE INITIAL INTERNAL BEVEL INCISION IS CARRIED APICAL TO THE CREST OF BONE CONTD. Connective tissue grafting harvesting techniques as well as free gingival graft. The crevicular incision, which is also called the second incision, is made from the base of the pocket to the crest of the bone (Figure 57-8). Vertical incisions increase flap mobility, thus facilitating better access to the operative area. The partial-thickness flap includes only the epithelium and a layer of the underlying connective tissue. Contents available in the book . After the administration of local anesthesia, bone sounding is performed to identify the exact thickness of the gingiva. Periodontal flaps can be classified as follows. Under no circumstances, the incision should be made in the middle of the papilla. Contents available in the book .. It is better to graft an infrabony defect than not grafting. 7. With this incision, the gingiva containing pocket lining is separated from the tooth surface. 6. 1- initial internal bevel incision 2- crevicular incisions 3- initial elevation of the flap 4- vertical incisions extending beyond the mucogingival junction 5- SRP performed 6- flap is apically positioned 7- place periodontal dressing to ensure the flap remains apically displaced These landmarks establish the presence and width of the attached gingiva, which is the basis for the decision. After administration of local anesthesia, bone sounding is done to assess the thickness of gingiva and underlying osseous topography. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. May cause attachment loss due to surgery. 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 most abundant cells during the initial healing phase are the neutrophils. This is especially important in maxillary and mandibular anterior areas which have a prime esthetic concern. The first documented report of papilla preservation procedure was by Kromer 24 in 1956, which was designed to retain osseous implants. 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. A crescent-shaped incision is sometimes used during the crown lengthening procedure. Journal of clinical periodontology. The bleeding is frequently associated with pain. A periosteal elevator is inserted into the initial internal bevel incision, and the flap is separated from the bone. 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. Clinical crown lengthening in multiple teeth. Tooth with extremely unfavorable clinical crown/root ratio. After this, the second or the sulcular incision is made from the bottom of the pocket till the crest of the alveolar bone. Undisplaced flap and apically repositioned flap. News & Perspective Drugs & Diseases CME & Education As already stated, depending on the thickness of the gingiva, any of the following approaches can be used. Laterally displaced flap. A detailed description of the historical aspect of various flap surgeries has been given in the previous chapter. The flap is then elevated with the help of a small periosteal elevator. Horizontal incisions are directed along the margin of the gingiva in a mesial or distal direction. 15c, 11 or 12d. This is also known as. This is especially important because, on the palatal aspect, osseous deformities such as heavy bone ledges and exostoses are commonly seen. 6. 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. Minor osseous recontouring may be done and the flap is then adapted into the interdental areas. Flap reflection till alveolar mucosa to mobilize the flap causes more post-operative pain and discomfort. Contents available in the book .. Contents available in the book .. Figure 2:The graph represents the distribution of various The challenging nature of scaphoid fracture and nonunion surgery make it an obvious target. This is a commonly used incision during periodontal flap surgeries. A progressive brous enlargement of the gingiva is a facet of idiopathic brous hyperplasia of the gingiva (Carranza and Hogan,; Gorlinetal., ).Itisdescribedvariouslyas bromatosisgingivae,gingivostomatitis,hereditarygingival bromatosis, idiopathic bromatosis, familial elephantiasis, and di use broma . Periodontal flap surgeries are also done for the establishment of . It is most commonly caused due to infection and sloughing of blood vessels. Displaced flap: Most commonly done suturing is the interrupted suturing. This incision causes extensive loss of tissue and is indicated only in cases of gingival overgrowth. Moreover, the palatal island flap is the only available flap that can provide keratinized mucosa for defect reconstruction. After thorough debridement, the area is then inspected for any remaining deposits on the root surfaces, granulation tissue or tissue tags. 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. DESCRIPTION. This is essentially an excisional procedure of the gingiva. These vertical incisions are now joined with a horizontal incision as shown in the following figure. The no. The base of the flap should be wider than the flap margin so that the blood supply to the flap is not jeopardized. 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. The modified Widman flap is indicated in cases of perio-dontitis with pocket depths of 5-7 mm. The undisplaced flap is therefore considered an internal bevel gingivectomy. 3. Because the alveolar bone is partially exposed, there is minimum post-operative pain and swelling. Contents available in the book . Hence, this suturing is mainly indicated in posterior areas where esthetics. 7. 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. Contents available in the book .. 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 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. Apically displaced flaps have the important advantage of preserving the outer portion of the pocket wall and transforming it into attached gingiva. The apically displaced flap is . Fundamental principles in periodontal plastic surgery and mucosal augmentationa narrative review. Step 5:Tissue tags and granulation tissue are removed with a curette. In areas with thin gingiva and alveolar process. Preservation of good blood supply to the flap is another important consideration. References are available in the hard-copy of the website. The area to be operated is then isolated with the help of gauge. The techniques that are used to achieve reconstructive and regenerative objectives are the papilla preservation flap8 and the conventional flap, which involve only crevicular or pocket incisions. Tooth with extremely unfavorable clinical crown/root ratio. The internal bevel incision should be scalloped into the interdental area to preserve the interdental papilla (see Figure 59-2). If extensive osseous recontouring is planned, an exaggerated incision is given. In areas with deep periodontal pockets and bone defects. 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. Access flap for guided tissue regeneration. Vertical relaxing incisions are usually not needed. After healing, the resultant architecture of the area should enhance the ease and effectiveness of self-performed oral hygiene measures by the patient. Contents available in the book .. Conventional flaps include: The modified Widman flap, The undisplaced flap, The apically displaced flap, The flap for regenerative procedures. The soft tissue is then retracted with tissue forceps and the scoring incision is given to separate the periosteum from the bone. As described in History of surgical periodontal pocket therapy and osseous resective surgeries the palatal approach for . The clinical outcomes of early internal fixation for undisplaced . In case, where osseous recontouring is done the flap margins may be re-scalloped and trimmed to adapt to the root bone junction. This incision is made from the crest of the gingival margin till the crest of alveolar bone. The incision is then carried out till the line angle of the tooth blending it into the gingival crevice. Click this link to watch video of the surgery: Modified Widman Flap surgery. It is discarded after the crevicular (second) and interdental (third) incisions are performed (Figure 57-5). . 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. Deep intrabony defects. 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. Contents available in the book .. . By doing this, the periosteum is cut and it becomes easy to remove the secondary flap from the bone. Locations of the internal bevel incisions for the different types of flaps. Flap adaptation is then done with the help of moistened gauze and any excess blood is expressed. Hereditary gingival fibromatosis (HGF), also known as idiopathic gingival hyperplasia, is a rare condition of gingival overgrowth. The bleeding is frequently associated with pain. While doing laterally displaced flap for root coverage, the vertical incision is made at an acute angle to the horizontal incision, in the direction toward which the flap will move, placing the base of the pedicle at the recipient site. 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. This flap procedure allows complete access to the root surfaces allowing their mechanical debridement and decontamination under direct vision. The horizontal incisions are used to separate the gingiva from the root surfaces of teeth. 12 or no. It is caused by trauma or spasm to the muscles of mastication. Contents available in the book .. The root surfaces are checked and then scaled and planed, if needed (Figure 59-3, G and H). 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. 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. After this, the second incision or the sulcular incision is made from the bottom of the pocket to the crest of the alveolar bone. 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. Contents available in the book .. In this technique no. Need to visually examine the area, to make a definite diagnosis. The internal bevel incision starts from a designated area on the gingiva, and it is then directed to an area at or near the crest of the bone (Figure 57-6). The cell surface components or adhesive molecules of bacteria that interact with a variety of host componentsand responsible for recognizing and binding to specific host cell receptors A. Cadherins B. Adhesins C. Cohesins D. Fimbriae Answer: B 2. The granulation tissue is removed from the area and scaling and root planing is done. Apically-displaced Flap Different suture techniques Course Duration : 8,9,10,15,16,17 Mar Early registration fees before15/2: 5500 L.E . However, there are important variations in the way these incisions are performed for the different types of flaps (Figures 59-1 and 59-2). (The use of this technique in palatal areas is considered in the discussion that follows this list. 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 distal wedge operation. The main advantages of this procedure are the preservation of maximum healthy tissue and minimum post-operative discomfort to the patient. . The secondary. Areas where post-operative maintenance can be most effectively done by doing this procedure. Frenectomy-frenal relocation-vestibuloplasty. A full-thickness flap is then elevated to expose 1-2 mm of the marginal bone. Following is the description of step by step procedure followed while doing a modified Widman flap surgery. Depending on the purpose, it can be a full . Step 2: The initial, internal bevel incision is made after the scalloping of the bleeding marks on the gingiva. Apically displaced flap. Platelets rich fibrin (PRF) preparation and application in the . 1. 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. Contents available in the book .. In this flap procedure, all the soft tissue, including the periosteum is reflected to expose the underlying bone. 35. A vertical incision may be given unilaterally (at one end of the flap) or bilaterally (on both ends of the 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. Our courses are designed to. The incision is made . Minimally invasive techniques have recently been described for the reduction of the isolated anterior frontal sinus fracture via a closed approach. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. 4. This incision is indicated in the following situations. Areas where greater probing depth reduction is required. Position of the knife to perform the internal bevel incision. 19. After the area to be operated has been irrigated with an antimicrobial solution and isolated, the local anesthetic agent is delivered to achieve profound anesthesia. 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. International library review - 2022-2023| , , & - Academic Accelerator 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 flap design may also be dictated by the aesthetic concerns of the area of surgery. 2. The incisions given are the same as in case of modified Widman flap procedure. Flap design for a conventional or traditional flap technique. After the removal of the secondary flap, scaling and root planing is done and the flap is adapted to its position. They are also useful for treating moderate to deep periodontal pockets in the posterior regions. Clin Appl Thromb Hemost. The incision is made not only around the facial and lingual radicular area but also interdentally, where it connects the facial and lingual segments to free the gingiva completely around the tooth (Figure 57-9; see Figure 57-5). Placement of the vertical incisions is absolutely essential in cases where the flap has to be re-positioned coronally (coronally displaced flap) or apically (apically displaced flap) from its original position. The internal bevel incisions are typically used in periodontal flap surgeries. 74. Residual periodontal fibers attached to the tooth surface should not be disturbed. Fugazzotto PA. Contents available in the book .. Apically displaced flap can be done with or without osseous resection. The initial or internal bevel incision is made (. Undisplaced flap, Clinical crown lengthening in multiple teeth. These . Patients at high risk for caries. It is the incision from which the flap is reflected to expose the underlying bone and root. Our main aim of doing so is to get complete access to the root surfaces of the teeth and bone defects around the teeth. An interdental (third) incision along the horizontal lines seen in the interdental spaces will sever these connections. Contents available in the book . The information presented in this website has been collected from various leading journals, books and websites. The intrasulcular incision is given using No. 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 57-4). Contents available in the book .. As discussed in, Periodontal treatment of medically compromised patients, antibiotic prophylaxis is must in patients with medical conditions such as rheumatic heart disease. Conflicting data surround the advisability of uncovering the bone when this is not actually needed. Flaps are used for pocket therapy to accomplish the following: 1. In other words, we can say that. Alveolar crest reduction following full and partial thickness flaps. Crown lengthening procedures to expose restoration margins. The patients were assigned randomly to one of the techniques, and results were analyzed yearly for up to 7 years after therapy. In the following discussion, we shall study in detail, the surgical techniques that are followed in various flap procedures. The use of continuous suturing in suture materials tearing through the flap edges and both plastic surgery (1) and periodontal surgery subsequent retraction of the flaps to less desirable has many advantages. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. When the flap is returned and sutured in its original position. Root planing is done followed by osseous surgery if needed. The presence of thin gingiva which does not allow placement of adequate initial internal bevel incision. One technique includes semilunar incisions which are . This flap procedure is indicated in areas that do not have esthetic concerns and areas where a greater reduction in pocket depth is desired.
