Abstract

The use of temporomandibular joint (TMJ) implants is considered to be a reliable treatment for some TMJ disorders when TMJ anatomical integrity is compromised. Among all of the designs proposed for these devices, intramedullary approaches are relatively new, and they may offer several advantages compared to those of past models with a lateral approach. In this report, we use finite element analysis (FEA) to calculate stress forces of a TMJ implant featuring a ferrule ring, which is frequently used in engineering as a stress distractor to reduce the splinter effect. Our analysis suggests that the addition of a ferrule ring in the TMJ implant helps to reduce von Mises stresses in the device and displacement forces in the volume and surface of the implant. These results suggest that including a ferrule ring in a TMJ implant may contribute to the stability and outcome of a TMJ implant by reducing component stress and displacement forces.
