The Restoration of Improperly Inclined Osseointegrated Implants

Improper implant angulation is one of the most difficult problems to overcome in the fabrication of implant-supported and implant-retained restorations. Several techniques using the UCLA abutment have been developed to solve these problems. The creation of large screw-access holes for moderate angulation and the fabrication of telescopic copings and overlay castings for severe angulation problems are discussed.
