The spline implant: design, engineering, and evaluation.

The design and engineering characteristics of the Spline dental implant were investigated. Compressive strength, rotational movement, resistance to cyclic loading and torsional strength were evaluated. The results of the mechanical test indicated that this implant/abutment complex is mechanically stable, has minimal rotational movement, improved resistance to screw loosening, and good interface fidelity. The data for the new design are compared with published data for other implant/abutment connections.
