Sometimes, periodontitis, infection or even trauma can affect the amount of bone that is left for implant placement. Loss of teeth for a significant amount of time, gravely affects bone loss in the jaws. In these cases, the bone can be regenerated through certain procedures to allow the rehabilitation of the site.
Furthermore, anatomical restrictions, such as the sinus cavity in the upper jaw may affect the treatment planning.
For this purpose, biomaterials, such as bone substitutes are used, acting as a scaffold to help new bone formation.
This procedure allows for graft placement in the sinus cavity, to make room for implant placement in the upper jaw. Bone graft is placed in the sinus cavity to maintmain the space and to gradually be replaced by new bone. In these cases, implant placement takes place a few months later, to ensure that the graft was successful.
In some cases, if it is possible, implants are placed in the same surgery.
