Tempromandibular Joint Reconstruction Via Computer-Assisted Surgery Simulation

Tempromandibular Joint Reconstruction Via Computer-Assisted Surgery Simulation

This study was planned to evaluate the accuracy of virtual surgical planning and three-dimensional (3D) printed templates in reconstruction of temporomandibular joint (TMJ) with costochondral graft.

Eight patients (15-45) years diagnosed with TMJ deformities were included. A composite skull model was obtained with data from computed tomography. A virtual surgical simulation was performed using Dolphin Imaging 11.7 Premium. Then, the virtual plan was transferred to the operative field using 3D (CAD-CAM) printed surgical template. These templates were designed by 3D printing using data from the virtual surgical simulation for optimum selection of the rib graft, accurate tailoring of chondral and costal graft and as an osteotomy guide.

The preoperative measurement including mouth opening, facial asymmetry and differences between the actual mandibular position and the virtual plan were analyzed

Inclusion Criteria:

• TMJ deformity due to osteoarthrosis, ankylosis, injury, and pathology
• medicaly free patients

Exclusion Criteria:

• bilateral TMJ deformity
• patients medically compromised
