Clinical Trial Summary

This study will examine whether adding an amnion-chorion membrane on top of the traditionally used collagen plug will lead to more bone formation compared to the collagen plug only.

Description:

Bone grafts and membranes are commonly placed to increase the amount of bone right after tooth extraction and before placing a dental implant. The primary objective of this study is to study the effect of a human amnion-chorion membrane (ACM) in an exposed-barrier ridge preservation technique to a control group without utilizing a ACM. 30 patients requiring a front tooth extraction will be recruited and randomized to receive bone grafting with or without an ACM.

Eligibility

Inclusion Criteria:

1. Age range: 20 to 80 years.

2. Patients must require tooth extraction (for incisors, canines and premolars) as a result of caries, periodontal disease, tooth fracture or deemed unrestorable.

3. Socket should be free of infection, less than 5mm of dehiscence

4. Patients interested in implant placement following tooth extraction.

Exclusion Criteria:

1. Allergies or hypersensitivities to study related medications such as chlorhexidine.

2. Hematologic disorders/blood dyscrasias.

3. Active infectious diseases of any kind.

4. Liver or kidney dysfunction/failure.

5. Uncontrolled diabetes (HbA1c > 8).

6. Active cancer treatment - such as active chemotherapy or radiation therapy.

7. Taking medications that will affect their bone healing (for example, bisphosphonates).

8. Metabolic bone diseases that affect bone healing such as osteoporosis.

9. Pregnant or lactating women (self-reported).

10. Smoke 10 or more cigarettes per day (self-reported).

11. Poor oral hygiene.
