Importance. The choice of management and orthodontic appliance construction is fundamental in planning and treatment of patients with mandibular micrognathia and/ or retrognathism.
The aim ― is evaluation of treatment effectiveness of patients with mandibular micrognathia and/ or retrognathism in incompleted facial skeleton growth period.
Methodoloty. Base of the research was Children dentistry and orthodontics department of E.A. Vagner Perm State Medical University. The object of the research is 98 patients aged from 5,5 to 16 (42 girls and 56 boys) with distal occlusion and mandibular micrognathia and/ or retrognathism. Data for study were lateral cephalograms, profile images, clinical study results before and after orthodontic treatment.
Results. It was determined that the largest increase in mandible size and its position normalization is observed in the treatment of patients with CS2, CS3 cervical vertebral maturation stages. In patients with CS5 cervical vertebral maturation stage and overjet more than 6 mm we use a symptomatic treatment principle for distal occlusion correction.
Results application area ― orthodontists practice.
Conclusions. This data may be used in prognosis of orthodontic treatment outcome and retentional period in patients with distal occlusion.
