Picture A shows bone thickness at the back of the upper jaw is only 5 mm. This is slightly inadequate for dental implants placement


A: Bone graft materials placed into the sinus cavity


By using an osteotome , the sinus floor is carefully lifted without tearing the sinus membrane. Bone graft materials, usually xenograft, is placed through the channel created to form bone.


A: Grafted Bone


With internal sinus bone grafting , longer dental implants can be placed in the back of the upper jaw. It is also a minimally invasive technique but a minimum of 5 mm existing bone thickness is required


A: Grafted Bone


Successful internal sinus lift bone grafting for the upper left second premolar. This enables a dental implant of adequate length to be placed.
