Maxillary sinus augmentation using different grafting materials and dental implants in monkeys

摘要: The aim of this study was to evaluate clinically, histologically and histometrically the use anorganic bovine bone matrix (i.e. Bio-oss) as a grafting material for maxillary sinus augmentation procedures. In 4 adult male rhesus monkeys Macaca mulatta) 1st, 2nd 3rd molars on one side jaws were extracted. remaining between alveolar crest bottom then reduced 3-4 mm. After 3 months, procedures performed in each monkey sinuses grafted with matrix. At that time, 2 IMZ pure titanium plasma coated implants immediately placed into augmented simultaneous implants-loaded group). additional similar these previously delayed Four months later, abutment connection all loaded gold-alloy bridge 6 until sacrifice animals). contralateral received same treatment exception extractions 7 after those opposite not loaded. Thus, groups implants-unloaded group group) obtained. Clinically, stable at day sacrifice. Histologically, exhibited significant formation integration particles new bone. Direct mineralized bone-to-implant contact greater implant placement than installed simultaneously augmentation. Furthermore, percentage direct residual area. It concluded facilitated osseointegration combination procedure seemed be preferable.
