The design and engineering characteristics of the Spline dental implan
t were investigated. Compressive strength, rotational movement, resist
ance to cyclic loading and torsional strength were evaluated. The resu
lts of the mechanical test indicated that this implant/abutment comple
x is mechanically stable, has minimal rotational movement, improved re
sistance to screw loosening, and good interface fidelity. The data for
the new design are compared with published data for other implant/abu
tment connections.
