Long-Term Evaluation of Conservative Treatment for Craniomandibular Disorders

두개하악장애환자의 보존적 치료에 관한 장기평가

In order to evaluate the prognosis of conservative treatment for Craniomandibular Disorders, 127 patients were subjected at the Dept. of Oral Medicine, Pusan National University Hospital from 1983 through 1991. All the changes of patients' symptoms and related factors were analyzed before treatment, after treatment and at follow-up examination by means of subjective and objective symptom indicies (Ai, AAI, SDS, Di, CDS, MCO). 1. All the indices were reduced and MCO became increased at follow-up examination (p<0.01). 2. As the duration after treatment became longer, all the indices became reduced and MCO became increased. 3. There were no significant differences in index scores according to sex and age. 4. Long-term patients showed higher index scores and lower MCO than short-term patients(p<0.01). 5. Chronic group showed higher index scores and lower MCO than acute group (p<0.05). 6. Macrotrauma group showed higher index scores and lower MCO than microtrauma group (p<0.05) 7. While muscle group showed the lowest MCO, muscle and joint group showed the highest index scores (p<0.01). 8. The long-term success rate of conservative treatment was more than 80% (p<0.01)
