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 as shown in the image on the left. This technique of bone grafting regrows bone, which enables the jaw to take the implant.
What is a single 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 single stage implant is when an implant is placed in the jawbone after the bone graft. After a few months for healing of the jaw, the prosthesis can be added on top of the abutment. Single stage implants are generally used when the quality of bone is good and the implant shows high levels of stability, or when appearance is not an issue.
