Abstract

The purpose of this study was to evaluate growth changes of dental, skeletal and facial integument measurements in persons with distal malocclusion and mandibular micrognathia and retrognathism.
Materials and methods.
We have performed open retrospective cohort X-ray study and analyzed 98 twin lateral cephalograms recorded before and after active dentomaxillofacial growth. All persons included in thestudy had no previous orthodontic treatment. Results and discussion. Cluster analysis reviled facial skeleton type determined skeletal, dental and soft tissue features in patients with distal malocclusion and mandibular micrognathia and/ or retrognathism. 20 subjects with normo- and hypodivergent facial skeleton type have tendency to moderate lower incisor protrusion, normal lower facial height and occlusal plane inclination before active dentomaxillofacial growth. Growth pattern in this group describes synchronous maxilla and mandible growth with stable sagittal imbalance of jaws position, increased in lower incisors protrusion (by 5.7±1.2°) and decreased in chin retrusion (by 5.3±1.3 mm). 29 subjects with hyperdivergent facial skeleton type before active dentomaxillofacial growth have increased lower facial height and normal incisors inclination. Growth pattern in this group describes increase in sagittal and vertical position disproportion of jaws (by 3.2±0.8° and 5.3±1.2°, respectively), clockwise occlusal plane rotation (by 5.7±2.1°), upper and lower incisors protrusion, lower lip and chin retrusion (by 1.1±0.9 mm and 5.7±2.1 mm, respectively) and increase in lower face height.
Conclusion.
Thuswise growth pattern and dental, skeletal, facial integument features of maxillofacial complex in untreated persons with mandibular micrognathia and retrognathism are caused by initial position disproportion formed in primary dentition.
