An RCT Comparing Xenograft and Allograft for Ridge Preservation

Following resolution of any periodontal issues in the region of study and administration of pre-surgical antibiotic, minimally traumatic extraction with periotomes and flap reflection will be performed. Allograft will be placed according to randomization schedule and in quantity to fill the extraction socket and mimic surrounding ridge dimension. X-link collagen membrane will be trimmed to extend at least 2 mm beyond the margins of the defect, and soft tissue flaps will be re-approximated using resorbable Vicryl® 6-0.

Following resolution of any periodontal issues in the region of study and administration of pre-surgical antibiotic, minimally traumatic extraction with periotomes and flap reflection will be performed. Xenograft will be placed according to randomization schedule and in quantity to fill the extraction socket and mimic surrounding ridge dimension. Non-x-link collagen membrane will be trimmed to extend at least 2 mm beyond the margins of the defect, and soft tissue flaps will be re-approximated using resorbable Vicryl® 6-0.
