Comparison of load transfer by angulated, standard and inclined implant abutments.
In order to avoid improper loading of implants, the type of prosthesis, as well as the number, localisation and position of the abutments, should be analysed. In this study three-unit fixed partial prostheses in the posterior mandibular region, supported by an angulated, standard or inclined Bonefit ITI Hollow-Cylinder two-stage implant connected to a natural tooth, are modelled and the stress distributions investigated using the finite element method. It is suggested that the angulated or inclined implant abutments may be recommended because of lower stress around the crestal region of the implant bone interface.
