To elucidate the relationship between biomechanics and stomatology, a brief review has been made on the studies and applications of biomechanics in the field of oral medical science. If was found that the principles of biomechanics were applied to explain the clinic and scientific phenomena almost in all sub-divisions of stomatology. Biomechanicsboosts the advancement of stomatology such as scientific researches, the inventions of biomaterials and applicationsand the improvement of medical care quality. Biomechanics is a subdiscipline belonging to the philosophy of medicine. Itis also beneficial to the clinicians in fostering and strengthening the thinking of differentiation of symptoms and signs indiagnosis and treatment. The author indicate that with the development of cytobiology and molecular biology, the biomechanical researches should be at the molecular and cellular level and have a better future.
