OBJECTIVE: Research is effective sequencing of measures for orthodontic treatment active period and unfavorable course of retention period predictors in patients with distal malocclusion, complicated by temporomandibular joint pain-dysfunction syndrome.
MATERIAL AND METHODS: The retrospective study consists of 102 case reports of patients from 18 to 37 (average age is 26.75±3.25 years) with distal malocclusion (Angle Class II division 2 subdivision) associated with temporomandibular joint pain-dysfunction syndrome.
RESULTS: Cases of successful treatment were 30.4% (n=31), semi-successful - 42.2% (n=43), semi-unsuccessful - 18.6% (n=19), unsuccessful - 8.8% (n=9). ANOVA analysis of orthodontic treatment stages reveals main risk factors for pain syndrome recurrence in retention period. The ineffective morphofunctional compensation and unsuccessful orthodontic treatment predictors are: incomplete pain syndrome elimination, persistent masticatory muscles dysfunction, distal malocclusion recurrence, condylar process distal position recurrence, deep overbite, upper incisors retroinclination for more than 15°, single posterior tooth interference.
CONCLUSION: Thus, pain syndrome recurrence prevention in retention orthodontic treatment period includes pain and masticatory muscles dysfunction elimination in pre-treatment period, physiological dental occlusion and condylar process central position in active period.
