Internally hexed and threaded root-form implants provide the clinician with many new treatment options for single tooth restorations. Coupled with an interlocking hex on the abutment, they provide stability for single tooth restorations while maintaining the options of screw or cement retention. Five techniques for fabricating single tooth restorations are presented. Clinical and laboratory evaluations of implant angulation, quantity and quality of the gingival tissues, and limitations in vertical height are discussed in relation to design, abutment selection, and laboratory procedures for each restoration. These techniques permit design of each restoration to meet the unique anatomic, functional and esthetic needs. Both screw-retained and cement-retained abutments and prostheses are discussed.
