{Abstract}: <B>UNASSIGNED: </B>The computer-guided approach for the patient-specific TMJ replacement is considered an ultimate reliable option in advanced cases. However, dislocation of the condylar head could happen with the concave fossa design. A flat design was described and used in this case.<BR><B>METHODS: </B>A 15 years old male patient with mandibular asymmetry and class IV recurrent ankylosis of the right TMJ received a patient-specific artificial joint with computer-guided gap arthroplasty and orthognathic corrective mandibular surgery for the left side. The fossa component was made entirely flat, and the patient was followed up over the next year.<BR><B>UNASSIGNED: </B>Customized TMJ prosthetic solutions are reliable in advanced cases, especially when facial corrections are indicated; however, the commonly used concave design showed reported dislocations requiring some design modifications as proposed in the presented case.<BR><B>CONCLUSIONS: </B>The flat fossa design of the artificial TMJ secures the same results as the anatomical fossa design without the incidence of dislocation.
