All underwent unilateral total joint replacement using customized prostheses planned with cone-beam computed tomography and magnetic resonance imaging. Interincisal mouth opening (IMO), pain (visual analog scale), jaw function (JF), and dietary intake (DI), assessed through a Likert-type psychometric scale, were recorded preoperatively and during a minimum follow-up of 24 months.  \nResults: All patients showed postoperative improvement. Median JF decreased from 6.5 to 3.5, DI from 8 to 1.5, and pain from 7 to 2. Postoperative IMO averaged 32 to 33 mm. One patient required revision for screw displacement without long-term functional compromise.  \nConclusion: Customized TMJ prostheses proved safe and effective, demonstrating consistent improvements in pain, mandibular function, and dietary capacity in patients with severe joint disease. This approach represents a reliable therapeutic option when combined with individualized surgical planning.  \nKey words: Temporomandibular joint, Joint prosthesis, Replacement arthroplasty, Jaw movements, Pain perception  \n[paper submitted 2025. 7. 29 / revised 1st 2025. 8. 30, 2nd 2025. 9. 23, 3rd 2025. 9. 30 / accepted 2025. 10. 12]  \nI. Introduction  \nThe temporomandibular joint (TMJ) plays a critical role inessential functions such as mastication, swallowing, speech, and airway maintenance. Constantly subjected to mechanical loading, it also serves as a growth center during childhood. In advanced stages of joint pathology, total joint replacement (TJR) with a customized prosthesis may represent the only viable therapeutic approach, particularly when restoring anatomical structure and function, or correcting esthetic deformities such as posterior vertical deficiency, often in conjunction with orthognathic surgery indicated for functional or esthetic  \nGonzalo Martinovic Guzmán  \nDepartment of Maxillofacial Surgery, Hospital Militar de Santiago, Av.
