Análisis mecánico entre diferentes conexiones y plataformas protésicas mediante el método de elementos finitos

Abstract

Dental implants have been widely used for the rehabilitation of total and partially edentulous patients; In the last decade, the mismatch, loosening and fracture of screws and / or prosthetic components in clinical treatments with supported implanted prosthesis, are referred to as mechanics that compromise function, health and oral aesthetics. For this reason it is important to know the biomechanics that includes aspects such as the distribution of stress on all the components, the behavior of the occlusal forces on the periimplant bone tissue along the axis of the implant. A condition for the stable and biocompatible operation of the screwed prostheses on implants is the balance of all the prosthetic components. The most known and used connections since the beginning of implantation are implants with External Hexagon (HE), the concept used by Branemark since the 60s and the most current connection with conical geometry internally as Cone Morse (CM). The latter has been highlighted by presenting favorable characteristics, the risk of loosening of the screw of the prosthesis and / or prosthetic components has been reduced.
