Quite often, patients come to see us several years after losing a back tooth, by which time a lot of resorption has occurred.
Adding Artificial Bone
This often means there isn't enough room to place an implant due to anatomical constraints of the jaws. In the top arch this often means the sinus’ prevent normal placement. In order to allow placement we would graft the sinus with an artificial bone substitute prior to implant placement or in some cases at the same time.
There are 2 ways of performing a sinus graft or “lift” . In this case we tented up the sinus at the same time as implant placement using saline to gently lift the sinus membrane before placing the graft material and then implant. For more extensive cases, we may place the graft material first, around 3-4 months before implant placement to allow the graft material to develop into mature bone.
The final crown was made and placed 4 months later with a great result.
