Analysis of Class III Skeletal Malocclusion that Require Orthognathic Surgery for Correction as Compared to Camouflage Treatment - A Retrospective Study

Abstract

Class III malocclusion is a complex anomaly . Not all adult class III patients will need surgical correction.
In the Indian population the incidence of a class III malocclusion is lesser than a class II. Orthodontic case
records were reviewed and analysed. Class III adult malocclusions were evaluated to estimate the prevalence
and the treatment protocol. From this evaluation of class III patients the span on close to a year report of 44
adult class III patients out of whom 10 patients required orthognathic surgery for correction . Surgery first
done in 2 cases and other cases were single jaw or bi-jaw surgery done using conventional approach.In the
camouflage treatment most of the cases were treated by non- extraction. Correct classification of adult Class
III malocclusion patients succeeded to a high degree. Pearson’s chi-square value is 1.867 and P value is 0.1
and the results of this study are not significant. The severity of the malocclusion should be used to determine
the treatment protocol.Orthognathic surgery was successful in 92% patients . Most of the camouflage studies
use mini-implants and non-extraction protocols. Surgical treatment done according to severity of class III
and patient compliance.Among the assessed population 44 patients had skeletal class III malocclusion and
in the adult patients 8 patients were treated with orthognathic surgery . The two main deciding factors to
conclude as the treatment plan was based on the severity of the malocclusion and the patient compliance.
Orthognathic surgery was successful in 92% patients
