What is a bone graft?

When a tooth is removed before an implant, the jawbone naturally goes through bone loss. To regrow the bone, and when it is not possible to place blocks of bone in the jaw, a soft bone substitute is added and a membrane is placed on top. This technique of bone grafting regrows bone, which enables the jaw to take the implant.

What is a two stage implant?

Implants are titanium screws that are placed within the jawbone to support a number of dental prostheses such as crowns, bridges and dentures. A two stage implant is when an implant is placed in the jawbone after the bone graft. The implant is completely covered by the jawbone. After a few months for healing of the jaw, the gum tissue covers the bone, and a second surgery is performed to attach an abutment for securing the prosthesis. Two stage implants are generally used when there is poor bone quality, and safety is of high significance.
