Volumetric and histological outcomes of platelet derived growth factor use in alveolar ridge preservation after dental extractions

This study will involve patients who require a dental extraction and subsequent dental implant placement. Their tooth will be removed as per standard protocols and the extraction site will be thoroughly cleaned, removing any infected tissue. The treating clinician will then mix a bovine and porcine derived bone grafting material with either platelet derived growth factor (0.5ml, half patient group, test) or saline (0.5ml, half of patient group, control) and placed into the extraction socket. The clinician will then place a porcine derived collagen membrane on top of the extraction socket and stitches will be placed. The procedure will add 5 minutes to the dental appointment. The treating clinician will be responsible for ensuring the application and the provision checked at regular study meetings. There is no adherence required by the subject.
