Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The study is a two-arm, parallel-design, randomized, prospective clinical trial designed to examine histologic wound healing following ridge preservation using bovine xenograft and porcine xenograft materials.This protocol involves procedures that are standard care. All materials are FDA-approved materials being used in an FDA-approved manner. The test group subjects will have extraction sockets grafted with porcine xenograft (Zcore). This test group will be compared to an active control group using bovine xenograft (Bio-Oss). The null hypothesis is that there will be no significant difference in formation of new vital bone between treatment groups (primary outcome). Each subjects will have a non-molar tooth extracted and the socket grafted with either test or control graft material. At the time of dental implant placement 18-20 weeks after tooth extraction a small core biopsy specimen will be removed from the implant site. The core biopsy will then be evaluated for the primary histologic outcome of % vital bone formation and secondary histologic outcome of % residual graft material.
