Sinus graft complications & management

The following clinical case shows several minor complications and management during different dental implant surgical stages. 

This is the case of a  28 years old healthy male who came to our clinic for dental implant rehabilitation of the posterior left maxillary area. After clinical and radiographic evaluation, the need for vertical and horizontal ridge bone augmentation was determined. Vertical augmentation was treatment planned to be obtained through lateral window sinus lift surgery accompanied by horizontal ridge augmentation using particulate bone grafting material and membrane. 

Two dental implants were placed 8 months post sinus lift surgery. During the osteotomy for the molar site implant, a small membrane perforation was identified, managed and controlled through the osteotomy site. Dental implants were placed and primary stability was obtained for both. 

Upon dental implant uncovery, 3 months after surgical placement,  bone loss was found on the molar site implant. We reduced the exposed implant threads with Implant-plasty using a fine diamond bur and a layer of HA xenograft bone grafting material was used to graft the facial aspect of the implant. 

The 3 year follow up X-ray shows good bone stability around the implants.
