AIM To compare dimensional changes in extraction socket of single rooted teeth, 6 months post extraction, when grafted with xenograft versus allograft.~PRIMARY OBJECTIVE~Horizontal and vertical dimensional changes of extraction sockets as evaluated in a CBCT scan immediately post extraction and 6 months post extraction when grafted with xenograft versus allograft.~SECONDARY OBJECTIVE~Difference in horizontal dimensional changes in xenograft and allograft groups as measured intra-operatively after extraction and at re- entry 6 months post extraction.~Difference in vertical dimensional changes in xenograft and allograft groups as measured intra-operatively after extraction and at re- entry 6 months post extraction.~Difference in histologic analysis of bone biopsy cores taken in xenograft and allograft groups at 6 months re-entry from osteotomy site.~Difference in newly regenerated supracrestal bone height and volume will be measured directly from the segmented images from MicroCT.~NULL HYPOTHESIS~There is no difference between the two groups for any of the parameters evaluated.
