Although tissue engineering of the temporomandibular joint (TMJ) structures is in its infancy, tissue engineering provides
the revolutionary possibility for treatment of temporomandibular disorders (TMDs). Recently, several reviews have provided
a summary of knowledge of TMJ structure and function at the biochemical, cellular, or mechanical level for tissue engineering
of mandibular cartilage, bone and the TMJ disc. As the TMJ enables large relative movements, joint lubrication can be considered
of great importance for an understanding of the dynamics of the TMJ. The tribological characteristics of the TMJ are essential
for reconstruction and tissue engineering of the joint. The purpose of this review is to provide a summary of advances relevant
to the tribological characteristics of the TMJ and to serve as a reference for future research in this field. This review
consists of four parts. Part 1 is a brief review of the anatomy and function of the TMJ articular components. In Part 2, the
biomechanical and biochemical factors associated with joint lubrication are described: the articular surface topology with
microscopic surface roughness and the biomechanical loading during jaw movements. Part 3 includes lubrication theories and
possible mechanisms for breakdown of joint lubrication. Finally, in Part 4, the requirement and possibility of tissue engineering
for treatment of TMDs with degenerative changes as a future treatment regimen will be discussed in a tribological context.
