Abstract
The complicated nature of the TMJ’s functional link with the local anatomy and masticatory muscles, as well as the technical constraints of replacing it, make it unrealistic to anticipate the replaced joint to revert to its premorbid, fully functioning state. Alloplastic materials have been reported for decades to be employed in the management of primary and secondary TMJ pathology. The primary reasons for TMJ reconstruction were the management maxillofacial deformities, ankylosis, osteoarthritis or TMJ replacement after ablative tumor surgery or trauma. Most of these early reports of the use of alloplastic material were single cases with no long-term follow-up; hence, complications were often unreported.
