Guided Bone Regeneration and Simultaneous Implant Placement

This study included 954 implants placed simultaneously with guided bone regeneration. The method was performed in cases with horizontal and vertical deficit (up to 3 mm) of the alveolar bone, measured by cone-beam computed tomography. We used pericardial collagen barrier membrane and the following bone grafting materials - BoneCeramic ( Institut Straumann - Basel, Switzerland), Cerabone ( Botiss, Berlin, Germany) and Maxresorb Inject (Botiss, Berlin, Germany). The patients were monitored for 2 to 5 years. The survival rate was 99, 5 %, as 5 of 954 implants failed. The mean marginal bone loss is 0, 094mm.
