A Systematic Review on the Management of Osseseous Defects During Dental Implant Placement
Keywords:dental implant, dehiscence, fenestration, systematic review
This systematic review focuses on the management of two types of osseous defects, i.e. dehiscence and fenestration that arise during the placement of dental implant in the edentulous area (delayed implant placement). A systematic online search of main database from 1975 to 2009 was made. Five randomised controlled trials have been identified based on the inclusion criteria. Different management procedures were identified, in which guided bone regeneration procedure was most commonly advocated. Resorbable and non-resorbable membranes were compared, in which resorbable membrane was preferred as it caused less complication of membrane exposure or risk of infection. The benefit of using bone substitute along with membrane in repairing bony defects cannot be concluded.
