CARDONA CARDONA, Eliana Cecilia; ESCOBAR RESTREPO, Julio Cesar; LATORRE CORREA, Federico  y  VILLARRAGA OSSA, Junes Abdul. Evaluation of the Behavior of Two Attachments Systems in the Tooth-Implant Connection Associated With a Distal Extension Removable Partial Denture: Finite Element Analyses. Int. J. Odontostomat. [online]. 2017, vol.11, n.3, pp.353-362. ISSN 0718-381X.  http://dx.doi.org/10.4067/S0718-381X2017000300353.

The aim of this study was to evaluate the behavior and stress distribution in the tooth-implant connection using two attachments systems associated with distal extension removable partial denture by finite element method (FEM). A rigid structure of mandible distal extension RPD was modeled and support by two different attachments, ERA-RV Sterngold® system in the first premolar and Locator, attachments Zest Anchors® on the implant 3.7 x 10 mm Tapered Screw-Vent® Zimmer located at the second molar. Two models were designed, one with a tooth-implant connection using a rigid attachment system in the tooth and resilient attachment on the implant and the other with a resilient system for both structures. The behavior was evaluated with loads of 200 N to 800 N in the vertical direction. No differences were observed in both models in all structures with respect to the values of von Mises and there were not permanents deformations on them. Furthemore, structures as bone and periodontal ligament were not affected in any models. The behavior of the tooth-implant connection in both models showed a favorable stress distribution using two attachments systems associated with RPD, subjecting it to different loads in the vertical direction.
