Custom-Made Alloplastic Prosthetic Implant to Treat Temporomandibular Joint Ankylosis in Pediatric Patients: A Case Study

Temporomandibular Joint (TMJ) ankylosis represents a fairly common condition which surgeons need to face. According to Rowe, it can be defined as a restricted functional capacity of the jaw with limited movements owing to bony or fibrous adhesions between the condyle and either glenoid fossa, disc or eminence (or both). It can become a disease which impacts patients’ daily life, who suffer from limited mandibular excursion with reduced intercisal opening, anterior open bite, inability to swallow, sleep disorders, and speech problems. In children this may also result in abnormal mandibular and facial growth. In this paper, we deal with the case of a child with an important momolateral ankylosis, previously treated surgically with Costochondral Grafting arthroplasty without success and subsequently treated with a custom-made prosthesis.
