Comprehensive diagnosis system for cleft palate patients with masticatory dysfunction.
Judgment from a functional aspect should be the method for classifying the level of disorders which appear in cleft palate patients. We gave questionnaires to the patients and attempted to generally classify the level of disorders (-, <plus-minus>, +) based on the information as to masticatory function in daily life. The sample was 75 consisting of cleft palate patients (Pre, Post, and under treatment), normal occlusion (10) and general orthodontic patients (25). There were 26 questions, and each question was given a respective scor
At the functional examination, we checked mandibular movement, EMG and occlusal sound. In the examination of mandibular movement, we measured eccentricify of (the) path of closeur during maximal opening and closing movement. As a result, we observed a significant difference in a frontal trace that the cleft palate patients have more eccentricity than those who have normal o
cclusion. In the fastest opening and closing movement, we found siginficantly abnormal observations in the cleft palate patients compared to those who have normal occlusion. In the examination of EMG,the cleft palate patients showed lower electric potential than those who have a normal occlusion. In the examination of muscle electric discharge (masseteric, temporal, and the difference between the two), many of the cleft palate patients showed an imbalance of the discharge. We could not observe obvious differences between the cleft palate patients and those who have normal occlusion in the examination of occlusal sound, swallowing, respiratory rhythm, etc. We councluded that those examination are not proper for screening tests.
The degree of the disability was classified into 3 groups (-, <plus-minus>, +) based on the results of the jaw movement, the EMG,and the questionnaires.Among 40 cleft palate patients no handicap in 2 cases (5%), slight in 6 cases (15%), medium in 15 cases (37.5%), and a seriously disabled in 17cases (42.5% Less
