A Clinical Trial to Evaluate the Safety and Effectiveness of MatrixOssTM Bone Graft
Sponsor:

Collagen Matrix

Brief Summary:

The objective of this clinical trial is to evaluate the efficacy and safety of MatrixOssTM Bone Graft in bone defect repair caused by tooth extraction.

Condition or disease

Dental Diseases

Intervention/treatment

MatrixOssTM Bone Graft plus Bio-Gide membrane

Phase

Not Applicable

Detailed Description:

This is a prospective, randomized, multi-center and parallel controlled clinical trial. It is planned to be carried out in more than 3 (including 3) hospitals with qualifications as a national-level clinical trial institution. Subjects included will be randomly assigned into the experimental group and the control group at a ratio of 1:1. Those in the experimental group will receive MatrixOssTM Bone Graft plus Bio-Gide membrane, and those in the control group will receive Bio-Oss Bone Graft plus Bio-Gide membrane. To evaluate whether the changes in alveolar ridge height from baseline to 24 weeks postoperative in the experimental group is non-inferior to that in the control group, so as to verify the efficacy and safety of MatrixOssTM Bone Graft developed and manufactured by Collagen Matrix, Inc. for bone defect repair caused by tooth extraction.}}
