A Conception versus Contention of Mandibular Axis

The mandibular axis is considered to be the axis along which the temporomandibular joint(mandibular condyle) in its terminal, and the retruded position has a purely rotational movement without any translation. Its significance in prosthodontics has been associated with the centric relation position and the fabrication of prosthesis with regards to this position. Its role during functional mandibular movements has therefore been questioned. This has led to various schools of thought on the presence/ absence, location, and the number of the hinge axis with proponents for and against this. This review article aims to discuss the concepts and controversies surrounding the hinge axis and the current clinical significance of this concept.
