Free Gingival Graft (free + gingival_graft)
Selected AbstractsLabial piercing and localized periodontal destruction , partial periodontal regeneration following periodontal debridement and free gingival graftDENTAL TRAUMATOLOGY, Issue 1 2008Ines Kapferer The purpose of this case report was to illustrate the destructive nature of a lip stud and to describe the successful treatment of this case. The lip stud was removed and supra- and subgingival debridement was performed. Because of a shallow vestibule, the absence of keratinized gingiva, and the strong frenulum insertion at the gingival margins, a free gingival graft was placed. Subsequently the patient demonstrated a significant amount of osseous regeneration and partial coverage of the recession, which has been clinically and radiographically (computed tomography) documented. [source] Hard tissue alterations after socket preservation with additional buccal overbuilding: a study in the beagle dogJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 10 2009Stefan Fickl Abstract Objectives: The aim of this study was to histometrically assess alterations of the ridge following socket preservation alone and socket preservation with additional buccal overbuilding. Material and Methods: In five beagle dogs four extraction sites were randomly subjected to one of the following treatments: Tx 1: The socket was filled with BioOss Collagen® and covered with a free gingival graft from the palate. Tx 2: The buccal bone plate was augmented using the GBR-technique, the socket was filled with BioOss Collagen® and covered with a free gingival graft. Tx 3: The buccal bone plate was forced into a buccal direction using a manual bone spreader. The socket was filled with BioOss Collagen® and covered with a free gingival graft from the palate. Tx 4: The socket was filled with BioOss Collagen® and a combined free gingival/connective tissue graft was used to cover the socket and for buccal tissue augmentation. For each experimental site, two histological sections were subjected to histometric analysis and evaluated for (i) vertical bone dimensions and (ii) horizontal bone dimensions. Results: All treatment groups showed horizontal and vertical bone loss. The mean vertical bone loss of the buccal bone plate was significantly lower in Tx 4 than in the other groups, while no statistical significant differences could be detected among the groups in the horizontal dimension. Conclusion: Overbuilding the buccal aspect in combination with socket preservation does not seem to be a suitable technique to compensate for the alterations after tooth extraction. [source] Tissue alterations after tooth extraction with and without surgical trauma: a volumetric study in the beagle dogJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 4 2008Stefan Fickl Abstract Objectives: The aim of this study is to evaluate whether tooth extraction without the elevation of a muco-periosteal flap has advantageous effects on the resorption rate after tooth extraction. Material and Methods: In five beagle dogs polyether impressions were taken before the surgery. The roots of the first and second pre-molars (P1 and P2) were extracted and the sites were assigned to one of the following treatments: treatment group (Tx) 1, no treatment; Tx 2, surgical trauma (flap elevation and repositioning); Tx 3, the extraction socket was filled with BioOss Collagen® and closed with a free soft-tissue graft; Tx 4, after flap elevation and repositioning, the extraction socket was treated with BioOss Collagen® and a free soft-tissue graft. Impressions were taken 2 and 4 months after surgery. The casts were scanned, matched together with baseline casts and evaluated with digital image analysis. Results: The "flapless groups" demonstrated significant lower resorption rates both when using socket-preservation techniques and without. Furthermore, socket-preservation techniques yielded better results compared with not treating the socket. Conclusion: The results demonstrate that leaving the periosteum in place decreases the resorption rate of the extraction socket. Furthermore, the treatment of the extraction socket with BioOss Collagen® and a free gingival graft seems beneficial in limiting the resorption process after tooth extraction. [source] Acellular dermal allograft for vestibuloplasty,an alternative to autogenous soft tissue grafts in preprosthetic surgical procedures: A clinical reportJOURNAL OF PROSTHODONTICS, Issue 2 2003Monish Bhola DDS Various vestibular extension procedures have been described in the literature over the past 6 decades, including the use of free gingival grafts. An acellular dermal allograft has been used as a substitute for autogenous soft tissue grafts in root coverage procedures. This clinical report describes the use of such an allograft as a substitute for palatal donor tissue in the vestibular extension of an edentulous maxillary arch with multiple frenum attachments before fabrication of a complete denture. In this patient, healing was uneventful, and 6-month clinical observations demonstrated an apical positioning of the mucogingival junction with an increase in vestibular depth, and the absence of multiple frenae. The acellular dermal allograft appears to be a useful substitute for autogenous palatal grafts in preprosthetic surgery. This approach has many advantages over the free gingival graft, including no donor site morbidity, unlimited availability, and better color match. [source] | ||||||||||
