Detailed Description

Records of 20 consecutive patients treated with dental implants placed in post-extraction sockets augmented with porcine derived bone and 20 consecutive patients with implants placed in native bone were reviewed. For each implant, the radio- graphs from the surgical appointment were compared to those from the last follow-up visit and evaluated regarding changes of marginal bone level over time.
