GARCIA SANCHEZ, Aitor et al. Post-traumatic reconstruction with custom prosthesis of the temporomandibular joint: Computerized surgical planning. Rev Esp Cirug Oral y Maxilofac [online]. 2011, vol.33, n.2, pp.53-60. ISSN 2173-9161.

Introduction: New virtual surgery planning techniques like CAD/CAM and advances in biomaterials have made it possible to undertake increasingly complex cases of temporomandibular joint reconstruction. The planning and preparation of custom alloplastic devices makes it possible to accurately accommodate anatomic structures. Dental and facial deformities often coexist with articular pathology. Using computerized planning methods, orthognathic surgery procedures can be combined with temporomandibular joint reconstruction in a single procedure. Material and methods: The authors' experience with computerized planning and surgical execution of three cases of bilateral articular ankylosis (6 joints) is presented with simulation of osteotomies, maxillomandibular movements and custom total alloplastic prosthesis design for the temporomandibular joint. Conclusions: A comprehensive approach to articular biomechanics, intermaxillary relations and dental occlusion is necessary to obtain predictable and satisfactory results. Computer modeling and the use of custom alloplastic devices allows exact, safe total articular reconstruction.
