Mechanical Evaluation of Implant-Assisted Removable Partial Dentures in Kennedy Class I Patients: Finite Element Design Considerations

The main purpose of this work was to construct a clinically valid numerical model mandibular Kennedy class I patient rehabilitated with conventional removable partial denture and another two implant-assisted dentures at different implant locations. selected classified as ASA its mandible geometry reconstruction performed by the conversion Cone-Beam computed Tomography (CBCT) scan raw medical data into 3D subsequent CAD file reverse engineering methods. soft tissue geometries were also included in well implants, ball attachments matrix. Moreover, periodontal ligament modelled offsetting mesh root surface each tooth. finite element results showed that installation dental bilateral edentulous regions helps providing support retention extension bases Removable Partial Denture (RPD) significantly reduces vertical anterior-posterior displacements, regardless position.
