I research _ treatment of maxillary radicular cysts The flap was then adapted and repositioned coro- nallywiththemarginalflapedgeadvanced0.2–0.5mm coronallytocement-enameljunction(CEJ).Thesutur- ing technique used in both groups was the same. The wound was sutured using a modified internal mat- tresssuture.1,3,4 Theproximalendsofthesutureswere knotted on to the orthodontic buttons, the suture in the interdental space was attached to two buttons on the adjacent teeth, which provided additional coronalflaprepositioningandcompleteclosureofthe previouslyopenedperiodontium,aswellaslong-term blood clot stability. Interrupted sutures were used in theareaoftheverticalincisionsuntilcompletewound closure.Theelasticligaturewasattachedtotheortho- dontic buttons without tension, providing additional immobilization of the teeth. Thesurgicalsitewasthencoveredwithacellulose dressing (Reso-Pac, Hager & Werken). The pressure bandage was prescribed for patients for a period of three nights. The post-operative medications pre- scribed are shown in Table 3 for each group. In the Figs. 12a & b_Sutured wound according to the proposed method. Figs. 13a & b_Post-op condition after one week. The suture tension is reduced and the gingival surface is covered with a thin fibrinous matrix (a). The interdental papilla has been replaced completely (b). Fig. 14_Post-op condition after one month. There is complete healing of the marginal periodontal tissue. The tissue in the surgical area is a more saturated colour due to revascularization and visible superficial vessels. Signs of soft tissue maturation and volume reconstruction. Figs. 15a & b_Tissue condition after two months. Complete soft-tissue healing and maturation. The contour of the marginal periodontal tissue is undergoing final maturation. Tissue regeneration continues owing to primary fixed position after suturing. The marginal periodontal contour has been restored according to the initial tissue position (a).
