Bone Expansion through Guide
A 53-year-old woman requests implant at #19 after redo #14 crown. The ridge is narrow (holding a 3.5x11.5 mm implant) and apparently low in density (Fig.1). Bone expansion seems necessary. Following use of 2.2 mm drill to the depth, bone expanders will be introduced (1.7/3.1 and 2.4/3.7 mm). After 4.0 mm cortical tap, a 4.0x11.5 mm implant is placed. If torque is high, use 3.5 mm drill. Postop 5x5 cm CT will be taken. Also take pre- and post-op photos of the buccal plate. Prepare surgical handpiece and a new thin fissure bur for ridge split as well as split saw block. Use a UF implant, in consistent with that at #11.
