Ridge Preservation in Molar Sites Comparing Xenograft Versus Mineralized Freeze-dried Bone Allograft: a Randomized Clinical Trial

• Status: Completed
• Phase: N/A
• Study type: Interventional

Summary

The objectives of the present investigation are; to compare the dimensional changes and the histological composition after the use of an allograft or xenograft and a resorbable membrane in ridge preservation in molar sites, to evaluate the influence of bone plates thickness on dimensional changes and the effectiveness of ridge preservation in limiting the need of sinus elevation.

Detailed description

Twenty-four patients in need of maxillary or mandibular molar extraction and subsequent implant placement were included and randomly assigned to a group; allograft or xenograft, plus a collagen membrane. Cone Beam Computed Tomographies were obtained after molar extraction and after five months. A bone sample was harvested at the time of implant placement and analysed by histomorphometry.
