简要总结
A non-resorbable PTFE (teflon) membrane will be compared to a resorbable collagen membrane when used for a post-extraction ridge preservation procedure to prevent the bone loss that typically occurs. The hypothesis is that there will be no difference in the clinical and histologic results between the two membranes.

Exclusion Criteria
- Patients with debilitating systemic diseases, or diseases that have a clinically significant effect on the periodontium.
- Presence or history of osteonecrosis of jaws.
- Patients who are currently taking IV bisphosphonates or who had IV treatment with bisphosphonates irrespective of duration.
- Patients who have been treated with oral bisphosphonates for more than three years.
- Patients with an allergy to any material or medication used in the study.
