Clinical Trial Summary

This study will involve placing donor bone into the back of lower jaw then covering with a newly designed titanium mesh. The mesh will then stay in the mouth for 4 months before it will be removed. Implants will be placed in the newly formed bone.

The goal of this study is to test how well using a newly designed titanium mesh and bone particles can grow bone in the back of the lower jaw. The investigators are also checking if the newly formed bone will stay around implants that will have been in use for 12 months.

• Alveolar Bone Loss

Intervention

Device:
• Bone/Mesh
A titanium mesh (Ti-Mesh) that is more porous than other materials will be placed in order to hold a spot for the bone particles to grow.
