Sulcular incision is now made around the tooth to facilitate flap elevation. 2011 Sep;25(1):4-15. The flaps are then apically positioned to just cover the alveolar crest. 6. It is also known as a partial-thickness flap. 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. Contents available in the book . Step 7:Continuous, independent sling sutures are placed in both the facial and palatal areas (Figure 59-3, I and J) and covered with a periodontal surgical pack. All three flap techniques that were just discussed involve the use of the basic incisions described in Chapter 57: the internal bevel incision, the crevicular incision, and the interdental incision. Then sharp periodontal curettes are used to remove the granulomatous tissue and tissue tags. This is mainly because of the reason that all the lateral blood supply to . A new technique for arthroscopic meniscectomy using a traction suture, , 2015-02, ()KCI . This is a commonly used incision during periodontal flap surgeries. In areas with a narrow width of attached gingiva. This procedure cannot be done on the palatal aspect as it has attached gingiva which cannot be displaced apically. The flap was repositioned and sutured and . This is a commonly used incision during periodontal flap surgeries. Crown lengthening procedures to expose restoration margins. Methods Twelve patients younger than 18 years with scaphoid nonunion, who underwent a VTMPF procedure without bone grafting , were included for this prospective cohort . These techniques are described in detail in. This preview shows page 166 - 168 out of 197 pages.. View full document. Areas where greater probing depth reduction is required. In other words, we can say that. Suturing is then performed to stabilize the flaps in their position. 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. PDF Case Report Idiopathic Gingival Fibromatosis Rehabilitation: A Case 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. Inferior alveolar nerve block C. PSA 14- A patient comes with . In the present discussion, we shall study in detail, the current concepts and advances in various periodontal flap surgeries. 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 Increase accessibility to root deposits for scaling and root planing, 2. Different suture techniques Course Duration : 8,9,10,15,16,17 Mar Early registration fees before15/2: 5500 L.E . This procedure was aimed to provide maximum protection to osseous and transplant recipient sites. The coronally directed incision is designated as external bevel incision whereas the apically directed incisions are the internal bevel and sulcular incision. Minor osteoplasty may be carried out if osseous irregulari-ties are observed. 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. Conflicting data surround the advisability of uncovering the bone when this is not actually needed. These meniscus tears are displaced into the tibia or femoral recesses and can be often difficult to diagnose intraoperatively. As described in History of surgical periodontal pocket therapy and osseous resective surgeries the palatal approach for . (1985) 26 modified this procedure to preserve anterior esthetics after flap surgery. Flaps are used for pocket therapy to accomplish the following: 1. Expose the area for the performance of regenerative methods. Two basic flap designs are used. ), 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. In this flap, only epithelium and the underlying connective tissue are reflected, leaving the periosteum intact. 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. The area is re-inspected for any remaining granulation tissue, tissue tags or deposits on the root surfaces. 12 or no. 4. Contents available in the book . Following is the description of step by step procedure followed while doing a modified Widman flap surgery. The apically displaced flap provides accessibility and eliminates the pocket, but it does the latter by apically positioning the soft-tissue wall of the pocket.2 Therefore, it preserves or increases the width of the attached gingiva by transforming the previously unattached keratinized pocket wall into attached tissue. Rough handling of the tissue and long duration of the surgery commonly result in post-operative swelling. By doing this, the periosteum is cut and it becomes easy to remove the secondary flap from the bone. The design of the flap is dictated by the surgical judgment of the operator, and it may depend on the objectives of the procedure. Diagram showing the location of two different areas where the internal bevel incision is made in an undisplaced flap. 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. Because the alveolar bone is partially exposed, there is minimum post-operative pain and swelling. 2. Swelling hinders routine working life of patient usually during the first 3 days after surgery 41. After the flap has been elevated, a wedge of tissue remains on the teeth and is attached by the base of the papillae. To overcome the problem of recession, papilla preservation flap design is used in these areas. If detected, they are removed. If the tissue is too thick, the flap margin should be thinned with the initial incision. 1. Placing periodontal depressing is optional. This type of flap is also called the split-thickness flap. Different Flap techniques for treatment of gingival recession (Lateral-coronal-double papilla-semilunar-tunnel-apical). Apically displaced flaps have the important advantage of preserving the outer portion of the pocket wall and transforming it into attached gingiva. A. Chlorhexidine rinse 0.2% bid was prescribed for 2 weeks, along with analgesics and the patient was given appropriate . The following statements can be made regarding periodontal regeneration procedures. 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. It is the incision from which the flap is reflected to expose the underlying bone and root. Minimally invasive techniques have recently been described for the reduction of the isolated anterior frontal sinus fracture via a closed approach. Connective tissue grafting harvesting techniques as well as free gingival graft. The incision is usually scalloped to maintain gingival morphology and to retain as much papilla as possible. After this, partial elevation of the flap is done with the help of a small periosteal elevator. 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 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. After the removal of the secondary flap, scaling and root planing is done and the flap is adapted to its position. This flap procedure utilizes two incisions referred to as primary and secondary incisions which contain tissue which has to be removed. Periodontal pockets in areas where esthetics is critical. It does not attempt to reduce the pocket depth, but it does eliminate the pocket lining. Contents available in the book . This incision is always accompanied by a sulcular incision which results in the formation of a collar of gingival tissue which contains the periodontal pocket lining. In this technique no. This technique offers the possibility of establishing an intimate postoperative adaptation of healthy collagenous connective tissue to tooth surfaces,2,3,5,6 and it provides access for adequate instrumentation of the root surfaces and immediate closure of the area. The incision is made . Suturing techniques. According to management of papilla: - Undisplaced flap - Apicaliy displaced flap - All of the above - Modified Widman flap. The granulation tissue is removed from the area and scaling and root planing is done. PPTX The Flap Technique for Pocket Therapy These are indicated in cases where interdental spaces are too narrow and when the flap needs to be displaced. 1. Loss of marginal bone as a result of uncovering the osseous crest. 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. This incision causes extensive loss of tissue and is indicated only in cases of gingival overgrowth. The crevicular incision is then placed from the bottom of the pocket till the alveolar crest. Flap adaptation is then done with the help of moistened gauze and any excess blood is expressed. Also, complicated or prolonged surgical procedures that require full-thickness mucoperiosteal flaps with resultant edema can lead to trismus. 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 triangular wedge of the tissue, hence formed is removed. Several techniques such as gingivectomy, undisplaced flap with or without osseous surgery, apically repositioned flap . 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. The Undisplaced Flap - Periodontal Disease - Click to Cure Cancer Areas which do not have an esthetic concern. 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. Flap reflection till alveolar mucosa to mobilize the flap causes more post-operative pain and discomfort. 4. In another technique, vertical incisions and a horizontal incision are placed. The triangular wedge of the tissue, hence formed is removed. 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 internal bevel incision may be a marginal incision (from the top of gingival margin) or para-marginal incision (at a distance from the gingival margin). 6. Suturing is then done using a continuous sling suture. Step 2: The initial, or internal bevel, incision is made. ), 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. 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. Conventional flaps include the modified Widman flap, the undisplaced flap, the apically displaced flap, and the flap for reconstructive procedures. Periodontal flap surgeries: current concepts - periobasics.com Apically-displaced Flap This complete exposure of and access to the underlying bone is indicated when resective osseous surgery is contemplated. 15 or 15C surgical blade is used most often to make this incision. All the pocket epithelium and granulation tissue from the inner surfaces of the flaps is then eliminated using sharp curved scissors or Castroviejo scissors. Hemorrhage occurring after 7-14 days is secondary to trauma or surgery. It is most commonly caused due to infection and sloughing of blood vessels. 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. PDF Clinical crown lengthening: A case report - Oral Journal In case of periodontitis with active pockets 5-6 mm deep or greater, that do not respond satisfactorily to the initial therapy. After administration of local anesthesia, bone sounding is done to assess the thickness of gingiva and underlying osseous topography. The thicker the tissue is, the more apical the ending point of the incision (see Figure 59-4). Papillae are then sutured with interrupted or horizontal mattress sutures. For the correction of bone morphology (osteoplasty, osseous resection). The step-by-step technique for the undisplaced flap is as follows: Step 1: The periodontal probe is inserted into the gingival crevice & penetrates the junctional epithelium & connective tissue down to bone. Step 6:Bone architecture is not corrected unless it prevents good tissue adaptation to the necks of the teeth. After pushing the papillae buccally, both the flap and the papilla are reflected off the bone with a periosteal elevator. 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. The interdental papilla is then freed from the underlying bone and is completely mobilized. Y5DDSEM1-Periodontology-2017-2018-MCQs Flashcards | Quizlet 6. Contents available in the book .. ), Only gold members can continue reading. The thickness of the gingiva. FLAP Flap yaitu suatu lembaran jaringan mukosa yang terdiri dari jaringan gingiva, mukosa alveolar, dan atau jaringan periosteum yang dilepaskan/ dissection dari permukaan tulang alveolar. Contents available in the book .. 15c or No. Undisplaced femoral neck fractures in children have a high risk of secondary displacement. Periodontal flaps can be classified as follows. Contents available in the book .. Contents available in the book . Horizontal incisions are directed along the margin of the gingiva in a mesial or distal direction. 5. 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. The buccal and the lingual/palatal flaps are then elevated to expose the diseased root surfaces and the marginal bone. Contents available in the book .. Contents available in the book .. The undisplaced flap and gingivectomy are the two techniques that surgically removed the pocket wall. 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. Fibrous enlargement is most common in areas of maxillary and mandibular . Most commonly done suturing is the interrupted suturing. ( intently, the undisplaced flap is perhaps the most commonly performed type ol periodontal surgery. This is also known as. 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. Ramfjord and Nissle 8 in 1974, modified the original Widman flap procedure . The area is then irrigated with an antimicrobial solution. In case, where osseous recontouring is done the flap margins may be re-scalloped and trimmed to adapt to the root bone junction. A technique using a mixture of bone dust and blood is called as a. bone blend technique b. bone swaging technique The classic treatment till today in developing countries is removal of excess gingival growth by scalpel but one should remember about the periodontal treatment which should be done before commencing the surgical part of . Access flap for guided tissue regeneration. 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. It can be used in combination with other procedures such as osseous resection, regenerative procedures, hemisection procedure and procedures involving wedge excision. 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). (Courtesy Dr. Silvia Oreamuno, San Jose, Costa Rica. that still persist between the bottom of the pocket and the crest of the bone. Once bone sounding has been done, a gingivectomy incision without bevel is given using a periodontal knife to remove the tissue above the alveolar crest. Contents available in the book .. 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 entire surgical procedure should be planned in every detail before the procedure is initiated. 2014 Apr;41:S98-107. One technique includes semilunar incisions which are . Flaps in which the interdental papilla is split beneath the contact of two approximating teeth, allowing the reflection of buccal and lingual flaps, are described as the conventional flaps. It is indicated where complete access to the bone is required, for example, in the case of osseous resective surgeries. The bone remains covered by a layer of connective tissue that includes the periosteum. Contraindications of periodontal flap surgery. As already stated, depending on the thickness of the gingiva, any of the following approaches can be used. The internal bevel incision in an undisplaced flap procedure is started at the same point where an external bevel incision is started in agingivectomyprocedure. Gain access for osseous resective surgery, if necessary, 4. Contents available in the book .. The blade is pushed into the sulcus till resistance is felt from the crestal bone crest. 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 2: The initial, internal bevel incision is made after the scalloping of the bleeding marks on the gingiva. Contents available in the book .. Technique-The technique that weusehas been reported previously (Zucman and Maurer 1965). Moreover, the palatal island flap is the only available flap that can provide keratinized mucosa for defect reconstruction. Ramfjord and Nissle6 performed an extensive longitudinal study that compared the Widman procedure (as modified by them) with the curettage technique and the pocket elimination methods, which include bone contouring when needed. The clinical outcomes of early internal fixation for undisplaced . These techniques are described in detail in Chapter 59. (1995, 1999) 29, 30 described . Although some details may be modified during the actual performance of the procedure, detailed planning allows for a better clinical result. The internal bevel incision accomplishes three important objectives: (1) it removes the pocket lining; (2) it conserves the relatively uninvolved outer surface of the gingiva, which, if apically positioned, becomes attached gingiva; and (3) it produces a sharp, thin flap margin for adaptation to the bonetooth junction. Tooth with extremely unfavorable clinical crown/root ratio. 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. This incision can be accomplished only if sufficient attached gingiva remains apical to the incision. 12D blade is usually used for this incision. Mitral facies or malar flush There is a tapping apex beat which is undisplaced. 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). For regenerative procedures, such as bone grafting and guided tissue regeneration. 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. 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. 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. Something with epoxy resin what type of impression a Journal of periodontology. Residual periodontal fibers attached to the tooth surface should not be disturbed. Vertical relaxing incisions are usually not needed. 11 or 15c blade. A detailed description of the historical aspect of various flap surgeries has been given in the previous chapter. This incision is indicated in the following situations. Before we go into the details of the periodontal flap surgeries, let us discuss the incisions used in surgical periodontal therapy. Contents available in the book .. Contents available in the book . 3. 1. Contents available in the book .. Following is the description of marginal and para-marginal internal bevel incisions. The flap was repositioned and sutured [Figure 6]. 2. The first, second and third incisions are placed in the same way as in case of modified Widman flap and the wedge of the infected tissue is removed. More is the thickness of the gingiva, farther is the incision placed to include more tissue which needs to be removed. 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. 2. PDF Effect of photobiomodulation on pain control after clinical crown
