In the case of muscular adaptation to occlusal interference, the phase of muscle relaxation is cut short, to the detriment of this metabolic regeneration. There is as a consequence, an accumulation of lactic acid within the muscle, the lactic acid induces the symptoms of muscle cramp. All muscle cramp is painful. Consequently, orthodontic treatment must also respect this relaxation phase of muscle physiology. Aesthetic dentistry and Masticatory Function .
Aesthetics are a major preoccupation for our patients.
Orthodontists define aesthetic criteria through which they choose between diverse appliances, both fixed and removable. According to the complexity of the treatment demands, the intervention of other medical specialities and maxillo-facial surgeons is sometimes required. At the precise moment that the tongue rises to crush itself against the hard palate, the maxillary and mandibular teeth are in occlusion, thus permitting the muscles of the floor of the mouth to provide, by their contraction, a solid base for the tongue. This phase is essentially totally dependent upon reflex action, which is never under conscious control. This adaptation is detrimental to the regenerative metabolic phase of the muscles.
