Direct Sinus Augmentation

A key to implant success is the quantity and quality of the bone where the implant is to be placed. The upper back jaw has traditionally been one of the most difficult areas to successfully place dental implants due to insufficient bone quantity and quality and the close proximity to the sinus. Sinus augmentation can help correct this problem by raising the sinus floor and developing bone for the ideal placement of dental implants.

The direct sinus lift is a surgical procedure completed in office. After sufficient anesthesia is achieved, a gum flap is raised. A small window is prepared in the side of the sinus wall. This exposes the sinus membrane, which is gently elevated, and bone-grafting material is added underneath. The material commonly used is a bovine product called Bio Oss. The window is then sealed with a resorbable collagen membrane and the gum is sutured closed. Antibiotics and nasal spray are normally prescribed after this procedure and you will not be able to blow your nose for one week. There can be significant swelling after this procedure and it is advised that you rest for 3-4 days.

Indirect Sinus Lift

In some instances, where only a few millimeters of space is required, it is not necessary to do a direct sinus lift and an indirect sinus lift can be performed. An indirect sinus lift is completed at the time of implant placement.

After sufficient anesthesia is achieved, the site is prepared for the implant to be placed. An instrument is then placed into the prepared implant site and the sinus floor is gently tapped upward and bone-grafting material is added underneath. The implant is then placed and the surgical site is closed with sutures. What is left is a dome of bone grafting material between the implant and the sinus floor that has lifted the floor of the sinus to allow implant placement.
