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 along with the abutment. After a few months for healing of the jaw, the prosthesis can be added on top of the abutment, as shown in the image on the left. 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.
Why would a bone graft be unnecessary?
A bone graft may not be required if the amount of bone in the toothless gap is enough to hold an implant.
