Case with a concave bone defect

It's a vertical bone defect 

In the case of a concave bone defect even in a vertical bone defect, the prognosis is better and the surgery seems to be more convenient

A concave vertical defect is seen on the right side of the lower jaw.

Bone grafting was performed using an absorbable membrane and implants were placed at the same time.

A secondary surgery was performed about 4 months later.

This is a photo after the final prosthesis.

It's about 7 years later. 

In the case of Concave defect, the prognosis seems to have narrowed in the long run.
