The major requirement for a successful dental implant is the presence of enough bone in the jaw to support implants. Due to various reasons like gum diseases, developmental defects, injury etc., some people do not have enough healthy natural bone to support the dental implants. In these cases, bone augmentation is required to rebuild bone, restore the natural jaw line and smile, and provide a strong and sturdy foundation for implant-supported teeth.
This can be done by various techniques but the most common techniques to augment bone are:
- Bone Grafting: Grafting is the procedure that involves building up or adding of bone in the jaw. The bone is taken either from some other location of patient’s body or can also be taken from a donor. In fact now a days, processed or synthetic bone materials are also used for bone grafting. It is a safe and highly successful procedure that is performed under local or general anaesthesia. After bone grafting, the area is allowed to heal for 3-4 months so that the grafted bone fuses properly in the gum and gives a strong base to the implant
- Sinus Lift (Sinus Augmentation or Sinus Elevation): Some people lose the back teeth of their upper jaw that are considered very difficult for restoration. The absence of these teeth causes enlargement of sinus cavity due to deterioration of natural bone over time. As dental implant procedure require healthy natural bone, a sinus lift surgery is required in these cases. The surgery involves addition of a bone below the sinus so that one or more implants can be placed on it. After sinus lift surgery, the area is allowed to heal for 1-3 months so that the grafted bone fuses properly in the gum and gives a strong base to the implant.
- To avoid Bone Grafting and Sinus Lift: But in full mouth cases, we are not doing Bone grafting and sinus lift procedure. Instead of that we can go for “ALL ON 4 concept” or we will go for Basal implants we can give teeth in 6-10 days of from implant placement.
