Peri-implant Marginal Bone and Soft Tissue Conditions Around Single Laser-Lok Implants Placed in Regenerated Extraction Sockets and in Native Bone: A 2-years Results of RCT

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.
