Contents available in the book .. Apically displaced flaps have the important advantage of preserving the outer portion of the pocket wall and transforming it into attached gingiva. After the administration of local anesthesia, bone sounding is performed to identify the exact thickness of the gingiva. Currently, the undisplaced flap may be the most frequently performed type of periodontal surgery. Contents available in the book . THE UNDISPLACED FLAP TECHNIQUE Step 1: Measure pockets by periodontal probe,and a bleeding point is produced on the outer surface of the gingiva by pocket marker. Also, complicated or prolonged surgical procedures that require full-thickness mucoperiosteal flaps with resultant edema can lead to trismus. Possibility of exposure of furcations and roots, which complicates postoperative supragingival plaque control. 12 or no. Click this link to watch video of the surgery: Areas where greater probing depth reduction is required. What are the steps involved in the Apically Displaced flap technique? Periodontal pockets in severe periodontal disease. Different Flap techniques for treatment of gingival recession (Lateral-coronal-double papilla-semilunar-tunnel-apical). Areas where post-operative maintenance can be most effectively done by doing this procedure. Conventional flaps include the. The modified Widman flap. The internal bevel incisions are typically used in periodontal flap surgeries. Conventional flaps include: The modified Widman flap, The undisplaced flap, The apically displaced flap, The flap for regenerative procedures. Hemorrhage occurring after 7-14 days is secondary to trauma or surgery. The primary incision or the internal bevel incision is then made with the help of No. 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%). 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 type of flap is also called the split-thickness flap. The incision is started from the greatest scallop of the gingiva around the tooth, which is usually present little distal to the mid-axis of the tooth in case of maxillary incisors and canines. Contents available in the book .. Deep intrabony defects. It can be used in combination with other procedures such as osseous resection, regenerative procedures, hemisection procedure and procedures involving wedge excision. Step 2: The mucogingival junction is assessed to determine the amount of keratinized tissue. The area is anesthetized and bone sounding is done to evaluate the osseous topography, pocket depth, and thickness of the gingiva. Following is the description of step by step procedure followed while doing a modified Widman flap surgery. Short anatomic crowns in the anterior region. The triangular wedge of the tissue made by the above three incisions is then removed with the help of curettes. 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. This drawback of conventional flap techniques led to the development of this flap technique which intended to spare the papilla instead of splitting it. Flap reflection till alveolar mucosa to mobilize the flap causes more post-operative pain and discomfort. Expose the area for the performance of regenerative methods. The objectives for the other two flap proceduresthe undisplaced flap and the apically displaced flapinclude root surface access and the reduction or elimination of the pocket depth. A vertical incision may be given unilaterally (at one end of the flap) or bilaterally (on both ends of the flap). Both full-thickness and partial-thickness flaps can also be displaced. 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. This incision is indicated in the following situations. The partial-thickness flap includes only the epithelium and a layer of the underlying connective tissue. It is better to graft an infrabony defect than not grafting. 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. . The term gingival ablation indicates? APICALLY REPOSITIONED FLAP/ PERIODONTAL FLAP SURGICAL TECHNIQUE/ DR. ANKITA KOTECHA 17,228 views Jul 30, 2020 This video is about APICALLY REPOSITIONED FLAP .more Dislike Share dental studies. The granulation tissue is highly vascularized, so it bleeds profusely. The buccal and palatal/lingual flaps are reflected with the help of a periosteal elevator. The most likely etiologic factor is local anesthetic, secondary to an inferior alveolar nerve block that penetrates the medial pterygoid muscle. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. 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. If the tissue is too thick, the flap margin should be thinned with the initial incision. It is also known as the mucoperiosteal (mucosal tissue + periosteum) flap. The bleeding is frequently associated with pain. After removing the wedge of the tissue the margins of the flap are undermined with the help of scalpel blades . Full-thickness or partial thickness flap may be elevated depending on the objectives of the surgery. . According to management of papilla: The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement.

The secondary incision is given from the depth of the periodontal pocket till the alveolar crest. 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. 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). 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). A. The para-marginal internal bevel incision accomplishes three important objectives. Laterally displaced flap. This is termed. 4. In 1965, Morris4 revived a technique described early during the twentieth century in the periodontal literature; he called it the unrepositioned mucoperiosteal flap. Essentially, the same procedure was presented in 1974 by Ramfjord and Nissle,6 who called it the modified Widman flap (Figure 59-3). The internal bevel incision is basic to most periodontal flap procedures. C. According to flap placement after surgery: The root surfaces are checked and then scaled and planed, if needed (. Rough handling of the tissue and long duration of the surgery commonly result in post-operative swelling. The horizontal incisions are used to separate the gingiva from the root surfaces of teeth. Contents available in the book . The modified Widman flap is indicated in cases of perio-dontitis with pocket depths of 5-7 mm. All the pocket epithelium and granulation tissue from the inner surfaces of the flaps is then eliminated using sharp curved scissors or Castroviejo scissors. Step 5:Tissue tags and granulation tissue are removed with a curette. Clubbing Tar Staining Signs of other disease Hands warm and well perfused Salbutamol and CO2 retention flap Radial rate and rhythm respiratory rate Pattern of breathing ASK FOR BP FACE Eye . It does not attempt to reduce the pocket depth, but it does eliminate the pocket lining. The flap is then elevated with the help of a small periosteal elevator. An intact papilla should be either excluded or included in the flap. The incision is made . Contents available in the book .. 5. Modified Widman flap, The most apical end of the internal bevel incision is exposed and visible. 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. Horizontal incisions are directed along the margin of the gingiva in a mesial or distal direction. This is a commonly used incision during periodontal flap surgeries. Suturing is then done using a continuous sling suture. Tooth with extremely unfavorable clinical crown/root ratio. Following are the steps followed during this procedure. When the flap is returned and sutured in its original position. Contents available in the book .. 6. As described in History of surgical periodontal pocket therapy and osseous resective surgeries the palatal approach for . A crevicular incision is made from the bottom of the pocket to the bone in such a way that it circumscribes the triangular wedge of tissue that contains the pocket lining. This incision is indicated in the following situations. ), Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), on 59: The Flap Technique for Pocket Therapy, Several techniques can be used for the treatment of periodontal pockets. A crescent-shaped incision is sometimes used during the crown lengthening procedure. 74. Contents available in the book .. Two basic flap designs are used. The incision is made around the entire circumference of the tooth using blade No. This flap procedure is indicated in areas that do not have esthetic concerns and areas where a greater reduction in pocket depth is desired. The key point to be remembered here is, more the thickness of the gingiva more scalloped is the incision. After pushing the papillae buccally, both the flap and the papilla are reflected off the bone with a periosteal elevator. Chlorhexidine rinse 0.2% bid was prescribed for 2 weeks, along with analgesics and the patient was given appropriate . Within the first few days, monocytes and macrophages start populating the area 37. 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 antibiotics should be started before the surg-ical procedure so that appropriate antibiotic levels are there in blood at the time of surgery to prevent spread of infection. Later on Cortellini et al. Modified Widman flap and apically repositioned flap. During the initial phase of healing, inflammatory cells are attracted by platelet and complement derived mediators and aggregate around the blood clot. It is caused by trauma or spasm to the muscles of mastication. Contents available in the book .. Sutures are removed after one week and the area is irrigated with normal saline. This is also known as Ledge-and-wedge technique. Fugazzotto PA. A full-thickness flap is then elevated to expose 1-2 mm of the marginal bone. 2)Wenow employ aK#{252}ntscher-type nailslightly bent forward inits upper part, allowing easier removal when indicated. 61: Periodontal Regeneration and Reconstructive Surgery, 63: Periodontal Plastic and Esthetic Surgery, 55: General Principles of Periodontal Surgery, 30: Significance of Clinical and Biologic Information. 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. 15 scalpel blade, parallel to each other beginning at the distal end of the edentulous area, continued to the tooth. Contents available in the book .. Placing periodontal depressing is optional. 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. Although some details may be modified during the actual performance of the procedure, detailed planning allows for a better clinical result. Unsuitable for treatment of deep periodontal pockets. Conflicting data surround the advisability of uncovering the bone when this is not actually needed. May cause esthetic problems due to root exposure. Triangular ( intently, the undisplaced flap is perhaps the most commonly performed type ol periodontal surgery. Contents available in the book . Enter the email address you signed up with and we'll email you a reset link. As soon the granulation tissue is removed, the clear bone margins and root surfaces are visible. Genon and Bender in 1984 27 also reported a similar technique indicated for esthetic purpose. 3. After the primary incision, tissue can now be retracted with the help of rat-tail pliers. The following statements can be made regarding periodontal regeneration procedures. An electronic search without time or language restrictions was . 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). In non-esthetic areas with moderate to deep pockets and for crown lengthening, this incision is indicated. The meniscus comma sign has been described for displaced flap tears of the meniscus. The first step . Displaced flap: Scaling, root planing and osseous recontouring (if required) are carried out. 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 . 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). The process of healing progresses through various phases of . 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. Square, parallel, or H design. 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. 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. 12 or no. 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. In this flap, only epithelium and the underlying connective tissue are reflected, leaving the periosteum intact. If a full-thickness flap has been elevated, the sutures are placed along the mesial and the distal vertical incision lines to. This incision, together with the initial reverse bevel incision, forms a V-shaped wedge that ends at or near the crest of bone. Residual periodontal fibers attached to the tooth surface should not be disturbed. Incisions can be divided into two types: the horizontal and vertical incisions 7. The incision is usually carried to a point apical to the alveolar crest, depending on the thickness of the tissue. Contents available in the book . Contents available in the book .. Pockets around the teeth in which a complete removal of root irritants is not clinically possible without gaining complete access to the root surfaces. Contents available in the book .. One technique includes semilunar incisions which are . If extensive osseous recontouring is planned, an exaggerated incision is given. This incision can be accomplished only if sufficient attached gingiva remains apical to the incision. The operated area will be cleaner without dressing and will heal faster. Contents available in the book . a. The first documented report of papilla preservation procedure was by. With the help of Ochsenbein chisels (no. 2. May cause esthetic problems due to root exposure. Areas which do not have an esthetic concern. The first incision or the internal bevel incision is then made from the bleeding points directed at an apical level to the alveolar crest. 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. The area to be operated is then isolated with the help of gauge. The periodontal flap surgeries have been practiced for more than one hundred years now, since their introduction in the early 1900s. This will allow the clinician to retain the maximum amount of gingival tissue, including the papilla, which is essential for graft or membrane coverage. The distance of the primary incision from the gingival margin depends on the thickness of the gingiva. This wedge of tissue contains most of the inflamed and granulomatous areas that constitute the lateral wall of the pocket as well as the junctional epithelium and the connective tissue fibers that still persist between the bottom of the pocket and the crest of the bone. Vertical incisions increase flap mobility, thus facilitating better access to the operative area. Contents available in the book . Undisplaced femoral neck fractures in children have a high risk of secondary displacement. Journal of clinical periodontology. After the removal of the secondary flap, scaling and root planing is done and the flap is adapted to its position. Interrupted or continuous sling sutures are then placed to secure the flaps in their place. As discussed in, Periodontal treatment of medically compromised patients, antibiotic prophylaxis is must in patients with medical conditions such as rheumatic heart disease. Contents available in the book .. 6. Different suture techniques Course Duration : 8,9,10,15,16,17 Mar Early registration fees before15/2: 5500 L.E . The margins of the flap are then placed at the root bone junction. 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. 1. 12D blade is usually used for this incision. It conserves the relatively uninvolved outer surface of the gingiva. Increase accessibility to root deposits for scaling and root planing, 2. 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. The incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. Our main aim of doing so is to get complete access to the root surfaces of the teeth and bone defects around the teeth. The area is re-inspected for any remaining granulation tissue, tissue tags or deposits on the root surfaces. It produces a sharp, thin flap margin for adaptation to the bone-tooth junction. 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.

To preserve the present attached gingiva or even to establish an adequate strip of it, where it is narrow or absent. Contents available in the book . As the flap is to be placed in an apical position, vertical incisions are made extending beyond the mucogingival junction. 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. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. This procedure was aimed to provide maximum protection to osseous and transplant recipient sites. Before we go into the details of the periodontal flap surgeries, let us discuss the incisions used in surgical periodontal therapy. In Figure 2, the frequency of the types of flap surgical techniques followed were analyzed. The granulation tissue is removed from the area and scaling and root planing is done. 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. 1.
