Abstract
The teeth and mouth carry out masticatory functions, respiratory functions, and speech functions.
The maintenance and improvement of these mouth functions, and managing them efficiently,
are important for general health. Also, it is very important to provide accurate treatment and
maintain longevity after treatment.
It has been reported that periodontitis is associated with arteriosclerosis, diabetes, aspiration
pneumonia and premature delivery. Serious occlusion and mandible deviation may result in TMJ
arthrosis, stiff neck, lumbago, or headache, etc. and asymmetry of the face and posture may be
negatively influenced. As social life has become complex and the number of patients who have
these symptoms has been increasing, orthodontic treatment and appropriate occlusal treatment are
recommended for the health of the whole body and the improvement of mouth function.
To investigate if interdisciplinary occlusal therapy improves systemic health and oral functions,
statistical analysis was done on 54 patients who received interdisciplinary occlusal therapy which
involved orthodontic, periodontal and prosthetic treatments, by comparing parameters before and
after treatment. The series of occlusal treatments resulted in improvements in health scores for
both whole body and oral functions. Statistically significant differences were observed. It was
suggested by these research that appropriate occlusal treatment wil lead to improvements in the
patient's systemic health and m⑳th functions.
During each individuals life stage, we clinicians should contribute to the maintenance and improvement
of the teeth exhibiting dental occlusions, since teeth are important organs that support
chewing, deglutition, and speech functions.
