Guided bone regeneration (GBR) has been used for the regeneration of bone in conjunction with the placement of dental implants, for augmentation of resorbed alveolar crests, and to treat localized ridge deformities. It is based on the principle of protecting bone regeneration against overgrowth of tissues formed by rapidly proliferating non-osteogenic cells. In this case, the space created by the Titanium mesh supported platelet rich fibrin membrane was filled by tissues with features of newly formed bone. No residual bone defects were observed and an increase of the alveolar width and height was observed. No untoward effects on bone regeneration were observed except membrane exposure after 4 and 1/2months. This case shows a satisfactory result concerning GBR technique or implant site development.
Alveolar ridge deficiency is considered a major limitation for successful implant placement, as well as for the long-term success rate, especially in the anterior maxillary region. Implants placed without regard for prosthetic position often results in dental restorations that are functionally and esthetically compromised. Adequate peri-implant bone support is essential for immediate and long-term implant stability, as well as for future esthetic outcome. To achieve this goal, augmentation of lost bone is often necessary.
A variety of surgical approaches have been proposed to enhance the alveolar bone volume. Guided bone regeneration (GBR) is the most common technique for localized bone augmentation. GBR, by application of cell occlusive membranes that mechanically exclude non-osteogenic cell populations from the surrounding soft tissues, has become a well-documented and highly successful procedure for localized augmentation of the atrophic jaw before or simultaneously with implant placement. This case report presents simultaneous approach of guided bone regeneration and implant placement in the maxillary anterior region with narrow ridge defect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
