METHOD OF CHEWING SYSTEM FUNCTIONING EVALUATION

摘要

FIELD: medicine.;SUBSTANCE: method of chewing system functioning evaluation refers to medicine, particularly to orthopaedic dentistry. A chewing test involves face bow recording in patients. A face bow index (FBI) is calculated by formula: where vtµ is a wave rate with the most frequent chewing wave length in a chewing phase, vhµ is a wave rate of the same amplitude in a chewing phase, t is a duration of a chewing phase actually (s), v is a number of masticatory movements in a chewing phase, Δt is a mean difference of the length of the most frequent wave and the other chewing waves (s). If the index is 2 and more, chewing system functioning is considered to be good. If the index is less than 2, lowered system effectiveness is observed.;EFFECT: application of the method aims at the objectification of human chewing system functioning evaluation when refining a diagnosis, allows evaluating chewing system functioning, its efficiency, proving the necessity and nature of remedial rehabilitation actions.;2 ex, 4 dwg, 1 tbl
