Guided bone regeneration (GBR) in implant therapy is especially useful for implant placement with dehiscence defects or fenestration defects. In alveolar ridges with marked facial/buccal depressions or in knifeedge alveolar crests, the position and direction of fixture placement is restricted. Improvement of alveolar ridge morphology becomes possible with GBR. This article describes a case in which the fenestration defect around an implant was treated by the application of platelet rich fibrin, a second generation platelet concentrate along with bone graft, and guided tissue regeneration membrane.

The mucogingival problems encountered, are addressed by various periodontal plastic surgical procedures one of which is the free gingival autograft. Grafting procedures can be performed traditionally by use of a scalpel or by the use of lasers.A case of gingival recession with a shallow vestibule, treated with a free gingival graft using an Er, Cr: YSGG laser with a wavelength of 2780 nm is presented here.The objective was to achieve complete root coverage with increased width of attached gingiva in relation to 31 and 41.The recipient bed preparation and harvesting of graft from donor site were done with the Er, Cr: YSGG laser using the appropriate laser parameters so as to ensure proper healing of the free gingival graft.The results showed uneventful healing of donor site with complete root coverage and increased width of attached gingival in the recipient site.The results of the therapy were assessed after 3 months.
