Demineralized Freeze-Dried Bone and Modified Hydroxyapatite Granules in Patients Requiring Immediate Dental Implants: A Comparative Study.

Objectives: The objective is to compare demineralized freeze-dried bone and modified hydroxyapatite granules in patients requiring immediate dental implants.

Materials And Methods: Forty patients for immediate dental implants were divided into Group I (demineralized freeze-dried bone allograft) and Group II (modified hydroxyapatite) based on the type of graft used. Success of graft was evaluated based on modified plaque index, gingival index, and Periotest at 3, 6, and 12 months follow up.

Results: The mean modified plaque index, gingival index, peri-implant sulcular depth, and Periotest were recorded at baseline, 3, 6, and 12 months at implant site and full mouth in both groups found to be nonsignificant ( > 0.05).

Conclusion: Both demineralized freeze-dried bone allograft and modified hydroxyapatite grafts were equally efficient in immediate dental implant placement sites.
