GIDDY, B.I.  and  VAN DER MERWE, J.. Parametric mandible reconstruction plate. S. Afr. J. Ind. Eng. [online]. 2020, vol.31, n.3, pp.253-261. ISSN 2224-7890.  http://dx.doi.org/10.7166/31-3-2444.

This study investigated the feasibility of a parametric mandible reconstruction plate in order to reduce surgical lead time, improve fit, and reduce residual stresses. The parametric plates were generated on the basis of simulated cephalometric measurements. A finite element analysis and a reconstruction plate/mandible fit test were performed on several combinations to determine whether the parametric plate provided a suitable alternative to conventional reconstruction plates in terms of fit and structural performance. The results indicated that the parametric plate is structurally superior to a conventional plate. The comparison test indicated that the parametric plate provides a reasonable approximation of mandible geometry.
