Occlusal disease is a comprehensive term for various
symptoms caused by occlusal discrepancy between the
habitual occlusal position (HOP) and muscular (MP) positions.
These are referred to as temporomandibular disorders (TMDs);
however, we like to use the term “occlusal disease” because
these symptoms are strongly related to the discrepancy
between HOP and MP. In 1959, Brill et al. postulated that the
coincidence of the muscle and tooth (intercuspal) position
constitutes a physiological condition, whereas the lack of
a coincidence of these two positions may be indicative of a
pathological condition. MP is defined as the position when
the jaw is closed by voluntary muscular activity with an
upright posture. HOP is an arbitrary closed position (tooth
position). Generally, MP is coincident with HOP; however, in
some individuals, it is not, which results in the manifestation
of various symptoms in these individuals. To alter a patient’s
occlusal habits and obtain a physiological muscular position,
the bite plate-induced occlusal position (BPOP) is used for
reference during voluntary jaw closing, while in an upright
position, and after wearing an anterior bite plate for a short
period of time. It has been reported that these two positions
do not coincide in patients with the temporomandibular joint
(TMJ) clicking sounds. Symptoms associated with occlusal
disease include oral dyskinesia, glossodynia (painful tongue),
burning mouth syndrome, tension-type headache, tinnitus,
earache, coxalgia and vertigo. Some cases will be reported and
the mechanisms of these symptoms will be discussed.
