Abstract
This study compared the clinical outcomes of recombinant human platelet-derived growth factor BB and beta-tricalcium phosphate (rhPDGF-BB/βTCP) with guided bone regeneration (GBR) in immediate implant placement in molar extraction sockets with buccal bone defects versus conventional implant placement. Twenty-eight implants were placed in fourteen patients. Clinical and radiographic evaluations assessed peri-implant soft and hard tissue parameters after 12 months. No implants were lost during the 1-year observation period, yielding a survival rate of 100%. Similar clinical and radiographic parameters were observed for both treatment groups. Use of rhPDGF-BB/βTCP and GBR in immediate implants in molars was as successful as conventional implant placement in fully healed extraction sites.
