Total Temporomandibular Joint Replacement by Samsid Customized Joint Prosthesis: A Case Report with 16 Years of Follow-Up

Total temporomandibular joint replacement (TMJR) is a surgical intervention employed for the management of advanced temporomandibular joint (TMJ) disorders, particularly when autogenous grafts are not recommended. With stainless steel implant of glenoid fossa attempted for the correction of ankylosis in the 1960s, total TMJR-which minimizes foreign body reaction and consists of highly biocompatible materials such as Cr-Co-Mo alloy, titanium, and ultra-high-molecular-weight polyethylene-began to be applied. These alloplastic prostheses are available in both standardized and customized forms, comprising components for the mandibular condyle and glenoid fossa. The present case report presents India's first TMJR in a 12-year-old female patient with TMJ ankylosis. Total TMJR was done in her with India's first customized TMJ prosthesis (Samsid TMJ prosthesis), which was designed and manufactured by the author for the first time in India. This study presents a 16-year follow-up of customized TMJR, addressing TMJ ankylosis. Our research showcases the long-term success of Samsid TMJ prostheses in improving pain, oral function, diet, and overall quality of life. The case report also highlights the potential of Samsid TMJ prostheses as a valuable solution for TMJ patients, emphasizing the importance of tailored solutions for lasting joint function restoration. The results presented indicate that the Samsid patient-fitted total TMJR system remains a secure, efficient, and dependable long-term treatment option for the particular patient demographic examined in this research.
