An Evaluation of Dentofacial Changes in Angle's Class II division 1 Patients using Advansync 2

Abstract

Background: The purpose of the study was to evaluate the dental, skeletal, and soft tissue changes of Advansync 2 appliance using photometric analysis.

Methods: The sample size consisted of 15 patients who reported to the department of orthodontics, seeking fixed orthodontic treatment. The effects of the Advansync 2 appliance were measured at two intervals. Results: After the nine months, p-values were observed to be less than 0.5, therefore statistically significant for parameters such as SNA, CO-A, WITZ, C0-Gn, ANB, UI-A (degree), LI-B (mm), LL-E plane, Nasolabial angle, Mentolabial angle, Facial angle, and L lip to chin. P-values were however observed to be greater than 0.5, therefore statistically insignificant for parameters such as SNB, C0-Go, UI A(mm), LI B(mm), UL-EPL, H LINE, FMA, Nose Tip angle, Nasofrontal angle, Nasomental angle, Upper-lip angle and U lip to chin.

Conclusion: AdvanSync 2 appliance brought about a change in Class II malocclusions through Co-Gn, Co-Go, ANB, FMA, UI-A(degree), UI A(linear) LI B (linear), UL-E plane, LL-E plane, H LINE, Nose tip angle, Nasolabial angle, Mentolabial angle, Nasofrontal angle, Nasomental angle, Facial angle, Upper lip angle, U lip to chin, and Llip to chin after nine months of appliance delivery.
