Direct Sinus Lift Surgery with Allograft for Dental implant placement in Upper jaw

Dr. S.M. Balaji explains the Sinus Lift Procedure to the Patient

The patient presented to Balaji Dental and Craniofacial Hospital, Teynampet, Chennai for treatment. He was seeking replacement of missing right upper molars with implants. Dr.  S.M. Balaji, Cranio-Maxillofacial Surgeon, examined the patient and ordered radiographic studies. There was inadequate bony height in the posterior maxillary region. This would lead to unsuccessful placement of dental implants by the conventional method. The patient then enquired if there were alternative treatments for implant placement.

Dr. Balaji then explained the sinus lift procedure to the patient. It would done by placement of an allograft, Bio-Oss through a window in the bone. This would become consolidated into new normal bone over a period of time. The new bone would serve as foundation for loading of normal biting forces on the implants. He was in total agreement with this treatment plan and agreed to surgery.

Successful Sinus Lift Procedure through Bony Window with Placement of Bio-Oss Allograft Material

After infiltration of local anesthesia, a window was then made in the bone with a round bur. The window was in the lateral wall of the maxillary antrum. This wall forms the boundary of the right maxillary sinus. The sinus floor was then lifted taking care not to damage the Schneiderian membrane. This membrane is the lining of the sinus. Implants were then placed in the bone. These implants will mimic the roots of natural teeth. Allograft mixture was then prepared using approximately 1.5 mL of the patient’s blood and Bio-Oss.

This was then packed into the sinus pocket tucked below the sinus lining. The height and width of the implant bearing bony area would thus increase. With time, there would be consolidation of the allograft into new bone. This new bone will provide a good bony foundation for the implants. Success of the implant treatment depends on this. The flaps were then closed with sutures.

Future Placement of Ceramic Prosthesis on Implants:

His next visit would be after three months. After confirmation of proper osseointegration, ceramic prostheses would then be attached to the implants. This would complete the patient’s rehabilitation process.
