Millions of individuals worldwide suffer from temporomandibular joint (TMJ) disorders and are characterized by pain and joint dysfunction. TMJ internal derangement (ID) is the most frequent type of temporomandibular disorders (TMDs). The ID of TMJ is defined as a joint dysfunction associated with an abnormal disc position. Identification and elimination of the causes of tissue breakdown of the TMJ that lead to ID are the key factors for successful treatment. The common causes for TMJ ID are trauma and parafunctional habits which lead to joint overload and degenerative changes in the articular structures, increased friction, and gradual disc displacement. Local and systemic inflammatory/degenerative arthropathies may also affect TMJ and cause ID. The aim of this chapter is to give comprehensive knowledge about the contemporary perspective of TMJ ID including diagnostic and therapeutic developments and innovations. Clinicians should establish the correct diagnosis and cause of the disease for appropriate management so that patients do not suffer from ineffective treatments. As an innovative development, TMJ replacements with alloplastic joint prosthesis and tissue-engineered structures hold promise for the future of management of TMJ ID.

Orthognathic surgery with reconstruction of the temporomandibular joint (TMJ) addresses conditions where dentofacial deformity (DFD) is present along with damage to the temporomandibular joint. A stable TMJ without signs of pathology is a basic prerequisite for successful orthognathic surgery. If pathology is present, it is necessary to first address the condition of the TMJ (through conservative, mini-invasive and surgical methods). Only after the condition of the TMJ is stabilized is it possible to surgically address DFD. Orthognathic surgery in conjunction with TJR is performed in a single operation, where precise planning of these surgical procedures is vital for their successful execution.
