Evaluation of three slip fit hexagonal implants.
Three external hexagonal implant systems were evaluated for machining tolerances and component fit. Mean implant hexagonal flat to flat size dimension varied from 2.685 to 2.700 mm, and a close correlation among corresponding analog hexagonal flat to flat dimensions for each system was noted. Rotational misfit for implant abutment matings varied from 1.6 to 5.3 degrees. Torsional strength for four different matings ranged from 122.7 to 175.8 N-cm. The data presented suggest a trend by some implant manufacturers toward improved tolerances, accuracy, fidelity, and consistency of implant components.
