Abstract
Purpose : The purpose of this study was to assess the possibility of implant-supported fixed prostheses as RPD abutments using 3D-finite element analysis.



Materials and methods : Finite element models of the mandible and teeth were generated based on a patients computed tomography (CT) data. The teeth, surveyed crowns, RPDs and IARPDs were created in the model using 3D software. With the generated components, three types of 3-dimensional finite element models of bilateral mandible were constructed: tooth-tissue-supported RPD with four abutment teeth (4TT), implant-tissue-supported RPD with four implants (4IT), implant-tissue-supported RPD with two implants (2IT).

Oblique force was directed at 11.54 degrees to the long axis of the crown from the buccal to the lingual direction and distributed to the central fossa and the lingual slopes of the buccal cusps of all maxillary premolars and molars in the models. Finite element analysis was performed with software (ANSYS 14.5
