Tratamiento de pacientes parcialmente edéntulos con prótesis dentoimplantosoportadas

Resum

The problem founded when restoring partially edentulous patients with osseointegrated implants is whether the implants should be connected to, or separated from the natural teeth. This dilemma is caused by the difference in mobility of teeth and osseointegrated implants. Brunski reported differences in intrusive stiffness for implants and teeth. However, there are several benefits for implants used in conjunction with natural teeth, which include: reduction of the number of implants needed for restoration, lower cost and maintenance of proprioception. This article presents a review on biomechanical aspects and some considerations of splinting teeth and implants, rigid and no rigid connections between implants and teeth are discussed. There are several areas of interest regarding the connection of implants and natural teeth, wich may provide different amounts of support depending on periodontal status. For a particular clinical situation, the selection of the tipe of the restorative interproximal connection, and quality of implant and teeth support are main issues.
