Automated generation of implant-supported bar attachment system for patient-specific edentulous mandible: parametric modelling and finite element analysis.

The aim of this study was to develop an algorithm to automatically generate a bar attachment system for a given mandible 3D model. The algorithm was implemented in Grasshopper to generate geometries for analyzing the effects of different bone loss and implant positioning scenarios on stress distribution under unilateral and trilateral loading conditions. The results indicate that stresses in the peri-implant bone are primarily influenced by bone loss, while stresses in the implant bar are affected by both bone loss and implant position. The algorithm offers the potential to create patient-specific bar attachment systems, aiming at individualised decision support.
