Abstract

The term internal derangement of the temporomandibular joint widely used to describe the displacement of the articular disc anterior to the condyle, and the eminence. The concept of system failure extends the term of internal derangement beyond this definition to include any interference with smooth joint movement, and functional rehabilitation is the primary goal of treatment regardless of the disk position. TMJ internal derangement is not a disease by itself, but it is a biomechanical dysfunction leading to system failure. Understanding the normal biomechanical function of the TMJ is important for successful management and expecting the treatment outcome understanding the consequences of internal derangement is important for understanding the disease progression. The aim of the current review is to discuss the biomechanical pathogenesis of the internal derangement and non-surgical treatment modalities based on the rationale of system failure.
