Clinical Trial Summary

The purpose of this study is to compare the speed of bone healing of the two most commonly used xenografts on the market, Bio-Oss® and Salvin-Oss® using a tooth extraction ridge preservation model in participants scheduled for tooth extraction and subsequent receipt of a dental implant. Researchers hypothesize that there will be additional vital bone at 16-20 weeks with Salvin-Oss®.


Description:

This study focuses on xenografts to preserve alveolar bone after tooth extraction prior to placement of a dental implant. Extraction sites that are not grafted for ridge preservation may lose up to 50 percent of their ridge width the first year after extraction. Xenografts are one of several products on the market used to maintain ridge width after tooth extraction. This study aims to compare the two most commonly used, FDA-approved xenografts on the market, Bio-Oss® and Salvin-Oss, in the preservation of alveolar bone after extraction of non-molar teeth. The primary objective of this study is to histologically evaluate and compare the percentage of new bone formation in healing extraction sockets of non-molar teeth grafted with Bio-Oss® versus Salvin-Oss®. The secondary aim is to observe clinical changes in ridge height and ridge width after grafting with these two materials.

Outcome

Type Measure Description Time frame Safety issue
Primary New Bone Formation at Extraction/Xenograft Site Measured by Histological Evaluation at 16-20 Weeks The amount of new bone formation at the tooth extraction/xenograft site as measured by the percent of vital bone, residual graft, and connective tissue observed in a histological sample (a bone biopsy) obtained at the time of dental implant insertion, 16-20 weeks after extraction. Baseline to 16-20 weeks
Primary New Bone Formation at Extraction/Xenograft Site Measured Clinically With Dental Probe at 16-20 Weeks The boney ridge height on both the buccal/lingual and width in area of the extraction/xenograft site as measured at time of implant placement with an intra-oral dental probe at 16-20 weeks after extraction. Percent change in ridge width from baseline is reported Baseline to 16-20 weeks
