Bone resorption around dental implants placed in grafted sinuses: clinical and radiologic follow-up after up to 4 years.

Abstract

Although this study involved a limited number of procedures, it confirmed that alloplastic and xenogenic materials can be reliable for bone regeneration in subantral cavities. The angular defects present both at the distal and mesial sides of the implants were comparable to those observed at implants placed in native bone.
