Clinical Trial Summary

The present study is a human, prospective, randomised controlled clinical trial will be conducted to explore and compare the clinical, radiographic and histomorphometric outcome of autogenous demineralised dentin(DDM) versus bovine derived xenograft(DBM) for socket preservation procedure.


Description:

- After local anesthesia a full thickness flap will be minimally reflected buccally and lingually around the tooth not exceeding 3mm apical to the alveolar crest.

- Tooth extraction will be performed using atraumatic extraction methods using Periotome.

- After extraction, the socket will be thoroughly curetted, inspected and irrigated with sterile saline solution.

- The socket satisfying the inclusion and exclusion criteria will be randomly allocated to either test or control group.

- Intra surgical measurements will be recorded.

- Socket preservation will be performed with either Demineralized dentin matrix DDM(TEST) or bovine derived xenograft DBM (CONTROL). Bone graft will be extended to the height of intra proximal bone.

- Collagen membrane will be placed over the grafted site extending approximately 3mm apical to buccal and lingual crest.

- Flaps will be approximated with sutures.
