Evolving recent advances in esthetic orthodontic treatment like clear aligners increased a need for esthetic treatment compared to conventional fixed appliances. The clear aligner is a clear, removable and made up of semi-elastic polyurethane material where it uses computer aided modeling technique for the purpose of fabrication and to move the teeth for establishing optimal occlusion. The objective of this case report was to explain an advanced orthodontic treatment method for correction of Angle’s class II subdivision malocclusion with proclined upper and lower incisors, increased overjet, midline spacing in upper & lower anteriors and upper midline deviation towards the left side by 3 mm relating to the facial midline using clear aligners. At the end of aligner treatment, class II malocclusion, spacing and proclination within short period of time was corrected compared to that of fixed appliance. The patient was satisfied about functional and esthetic outcome after 1 year follow up

Malocclusion is a common development disorder which can create a negative impact on children and adults. Angle had classified malocclusion into class I, class II , class III based on upper and lower molars. Prevalence of malocclusion varies among different populations based on their ethnicity. This study aims to find out the prevalence of class II dental relation among permanent dentition patients in our population. The study is done among patients who came to the dental college. Patient data is collected from dental case records of patients with permanent dentition. With the collected data, class II malocclusion prevalence among patients were evaluated. Results were analyzed using SPSS statistical software. Out of 37756 patients, 1017 patients (2.69%) had class II malocclusion among permanent dentition. 52.95% were males and 47.05% were females. Prevalence of Class II div I was higher (88%) than class II div 2 (12%). Chi square test done between type of malocclusion and gender was found to be insignificant with P value of
0.564. Within the limitations of the current study, it was found that prevalence of class II malocclusion was less in our population with no significant difference in distribution among males and females.
