Immediate Bridge Following Sinus Lift and Implantation
A 54-year-old lady has severe toothache in the upper left region. Exam reveals a posterior 4-unit bridge (Fig.1 B); one of the abutments (#15) needs root canal therapy (RCT, Fig.2). The bridge is temporarily recemented after RCT. Two implants are planned (4x14 mm and 5x11 mm at the sites of #13 and 14) with sinus lift/graft (Fig.3).
Make 2 surgical stents before surgery, one for surgery, the other for the 4-unit provisional bridge. Place short abutments following implantation. Occlusion of the bridge should be light.
