Abstract
The internal and external-hex connections of the Neoss and 3i implant systems, were compared in a three-dimensional Finite Element Analysis. Chewing forces of 200, 500 and 1000N and abutment screw preloads of 110, 320 and 550Nmm were studied. The connection type strongly influences the stress profile within the crown, with the external-hex connection exhibiting greater stresses than the internal-hex.
