WHY ARE SINUS LIFTS AND BONE GRAFTS
UNNECESSARY WITH THESE SYSTEMS?
The sinus is located above the pre-molar and molar teeth. The bone in the area below the sinus is relatively thin in normal circumstances and so people suffering from bone recession in this area are unable to receive implants without a sinus lift and bone graft, which involves raising the sinus membrane and grafting bone onto existing bone, as illustrated (below, left).
Immediate loaded implants, as can be seen in the illustration (below, right), can be fitted at an angle of up to 30 degrees, thereby avoiding the sinus area and the need for a sinus lift and bone graft.
