Abstract:Three-dimensional rapid prototyping (3D RP) models based on volumetric image data acquired by various modalities have been used in presurgical planning, implant design, and medical education. To the best of our knowledge, cone-beam computed tomography (CBCT) is the best modality for imaging bone components of the temporomandibular joint (TMJ). 3D RP models of the TMJ are also applied for reconstruction design, simple anatomical evaluation, and education. Although 3D RP models of the TMJ already provide much information during preoperative and anatomical evaluation, we intended to expand the utility of these models. This paper presents two examples of the application of 3D RP models of the TMJ based on CBCT imaging data and briefly reviews the usage of 3D RP models.
