A sinus lift, also known as sinus augmentation, is a surgical procedure that adds bone to the upper jaw in the area of the molars and premolars, just below the sinus cavity. It’s often necessary when there's not enough natural bone height to support a dental implant in the back upper jaw—especially after bone loss or long-term tooth absence. At 100 Dental in Southlake, we carefully perform sinus lifts using safe, advanced techniques to gently raise the sinus membrane and place bone graft material. This allows for stable, long-term implant placement and helps restore full function to your smile.
