Abstract
The study of fatigue of L-wrought wire clasp in distal extension acrylic removable partial dentures with and without distal wrought wire rest on posterior abutment was done. The cone beam computed tomography data of partially edentulous mandible, with missing tooth 36 37 38 46 47 48, was used to construct the digital model of mandible. The two digital models of distal extension acrylic free-end saddle removable partial dentures, with L-wrought wire clasp on both posterior abutments, with and without distal wrought wire rest on posterior abutment were made and then combined to mandibular digital model. The digital models were imported into ANSYS Workbench software to create finite element analysis by applying unilateral static load at distal extension for 5 point of 40 N each. The von Mises stress and displacement of the prosthesis and abutment teeth were calculated for the number of loading cycles of L-wrought wire clasp. The result revealed the wrought wire rest, L-wrought wire clasp and posterior abutment were displaced mesially and no fatigue from occlusal loads on L-wrought wire clasp with and without wrought wire rest. The L-wrought wire clasp with distal wrought rest resulted in slightly lower stress than without distal wrought wire rest. It implies that L-wrought wire clasp with or without distal wrought wire rest can be designed for posterior abutment of distal extension base.
