The purpose of this study is to document and evaluate how protective covering materials (a barrier membrane called OSSIX-Plus) can help preserve bone size after a tooth is removed. As you know by now, dental implants can only be placed when enough bone is found and this protective covering may help the healing of your bone after the tooth is removed. For this study, the investigators are asking that records taken during procedures (pictures of teeth only, notes) can be used for publications.

Ages Eligible for Study:   18 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Systemically healthy subjects with 1 maxillary premolar tooth requiring extraction
  • Residual extraction sockets must have < 80% bone loss in all dimensions (3 or 4-walled bony defects)
  • Nonsmokers (individuals who quit smoking at least 6 months prior to the study will be allowed to participate)
  • Subjects willing and able to comply with all study-related procedures
  • Including maintenance of good oral hygiene
  • Compliance with re-evaluation appointments
  • Subjects who read
  • Understand
  • Willing to sign an informed consent statement

Exclusion Criteria:

  • Inadequate zone of keratinized gingiva (KG) or alveolar mucosa to obtain primary wound closure of the surgical site
  • Presence of acute infections at the time of tooth extraction
  • Clinically significant or unstable (as defined by the investigators) systemic diseases affecting bone or soft tissue growth
  • Other renal
  • Hepatic
  • Cardiac
  • Endocrine
  • Hematological
  • Autoimmune or acute infectious diseases that makes interpretation of the data more difficult
  • History of head & neck radiation therapy

  • Biphosphonates
  • Medications affecting bone turnover
  • Antibiotics for > 7 days or any investigational drug
  • Patients who are or become pregnant during the length of the study
  • Sites in which one or both adjacent teeth are missing
