Early correction of class II division 1 by the modified fixed lingual mandibular growth modificator
Journal Title: IP Indian Journal of Orthodontics and Dentofacial Research - Year 2017, Vol 3, Issue 2
Abstract
Objective: The aim of this study was to assess the skeletal and dental changes of Class II division 1 malocclusion corrected by Modified Fixed Lingual Mandibular Growth Modificator (MFLMGM). Materials and Method: This study was conducted on a sample of 15 patients, which they presented with CL II division 1 malocclusion. Overjet was ≥ 8mm. Age ranges from 9-12 year. The maxilla was protruded and the mandible was retruded. Results: The results showed that the maxillary growth was not significantly affected by MFLMGM treatment while the mandible was advanced. The overjet reduction was 7mm, and overbite reduction was 2.2mm. A reduction of 2.9o in ANB was largely due to an increase of 2.3o in SNB, slight non-significant increase in posterior facial height (S-GO) was 1.4mm. The changes in the other vertical skeletal relationships were negligible. Conclusion: Modified Fixed Lingual Mandibular Growth Modificator (MFLMGM) was successful in treatment cases of severe overjet skeletal Class II division 1 malocclusions. MFLMGM can control degree of severe overjet in treatment of skeletal Class II division 1 malocclusion by Gurin lock. Distal movement of upper molars were an important required in correction of molar relationship.
