Objectives: The aim of this study was to radiographically and clinically compare dimensional alterations during ridge preservation between using two types of membrane （physically and chemically cross-linked）.
Materials and methods: A newly developed physically cross linked membrane （Ovis BCP/Collagen membrane®） and A chemically cross linked membrane （Cross-linked collagen membrane®） were applied during the ridge preservation procedure in test and control groups （total 6 subjects）, respectively. Cone-beam computed tomography scans were obtained at the day and 3 months after the ridge preservation procedure. For measuring volumetric change of alveolar ridge with optical scanner, alginate impressions were taken three times （before, 7 days and 3 months after the ridge preservation procedure. Results were analyzed using the independent t-test and the nonparametric Whitney U test.
Results: Change of extraction socket dimension, width, height and quantity of bone tissue showed no significant difference between two membranes.
Conclusions: Newly developed physically cross linked membrane in ridge preservation procedure showed comparable clinical/ radiographical result to chemically cross linked membrane.
