Prevalence of Class III Malocclusion in Known Population and Its Treatment with Myofunctional and Orthopaedic Appliances.

Abstract

Background: This study was conducted to assess the prevalence of class III malocclusion in a known population and its treatment using myofunctional and orthopaedic appliances.

Material and methods: This study comprised of 100 participants who underwent oral clinical examination. The prevalence of malocclusion was assessed. The subjects were explained about the procedure and were asked for written consent. The subjects who were willing to participate in the study had been included in the study. Different myofunctional and orthopaedic appliances had been fabricated for the subjects with class III malocclusion. Statistical analysis was conducted using SPSS software.

Results: In this study, there were 100 subjects, of which, malocclusion was observed in 46 (46%) subjects. Among 46 subjects with class III malocclusion, 25 (54.3%) were male and 21 (45.6%) were females. For skeletal class III malocclusion, reverse pull headgear was given in 12 subjects and chin cup was given in 10 subjects. For dental class III malocclusion, reverse twin block appliance was given in 11 subjects, Frankel III appliance was given in 9 subjects and removable mandibular retractor was given in 4 subjects.

Conclusion: The prevalence of malocclusion in this study was 46%. Majority of the subjects were male. The skeletal malocclusion had been corrected with orthopaedic appliances like reverse pull headgear and chin cup while the dental class III malocclusion had been corrected with myofunctional appliances like removable mandibular retractor, Frankel III appliance and reverse twin block appliance.
