Guided bone regeneration for fenestration defects in dental implants.
Guided bone regeneration has been applied in implant dentistry for increasing the width and height of the alveolar ridge in areas with insufficient bone. Various materials and techniques have been used for this purpose. It refers to a surgical procedure by which utilizing a mechanical barrier to create a secluded space around the defect to permit bone regeneration without the competition of other tissues. This report presents a case with buccal fenestrations on maxillary implant sites observed during a surgical procedure. An allograft and a non-resorbable membrane were concomitantly used to increase the width of the alveolar ridge. Hard tissue regeneration was evident clinically. The implants were restored for functioning and followed for 2 years. Factors affecting outcomes are also discussed. Membrane stability and the space-making effect remain the keys to success.
