Loss of maxillary molar teeth leads to rapid resorption of bone in the alveolar process below the maxillary sinus floor. The sinus floor augmentation procedure is one of the most predictable grafting procedures available for placing dental implants in the severely atrophic posterior maxilla. Sinus augmentation is classified according to residual alveolar bone height. When the residual bone height is 3~4 mm, 1-step lateral approach is recommended.
This clinical case report presents patient subjected to a maxillary sinus lift (Lateral approach) and immediate implant placement (TSIII ) with synthetic bone grafting.
Materials & Methods
Right maxillary molar and premolar teeth (Teeth number 17, 16, 15, 14) were missing state. In pre-surgical computed tomographic scan images, residual bone height was about 3.3 mm. First stage implant surgery was performed using TSIII with sinus lift. Lateral approach for the open-window method using round bur and for sinus lifting with placement of alloplast (Osteon II ) was carried out. Second stage surgery was performed after 4 months of healing.
