Abstract

Objectives: To evaluate the treatment effects of AdvancSync 2 TM in patients of skeletal Class II malocclusion in selected skeletal, dental, soft tissue and airway parameters. Materials and Methods: Pretreatment and post-functional lateral cephalograms of 12 patients (06 males and 06 females with mean age of 14.25+0.75) with skeletal Class II malocclusion treated using AdvanSync 2 TM were evaluated. Paired t-test and Wilcoxon rank-sum intraclass correlation (ICC) test results were calculated. Results: Statistically significant changes were found in skeletal parameters of SNB, Wits, maxillo-mandibular differential, Björk’s sum, basal plane angle, Sn-GoGn, lower anterior facial height (LAFH), Na-perp-Pog. Changes in dental parameters U1-NA (angular and linear), L1 to NB (angular and linear), U1-SN angle, IMPA, Inter-incisal angle, L1 to A-Pog and U1 to A-Pog were also observed to be statistically significant at T1. Soft tissue skeletal convexity and nasolabial angle improved significantly post treatment, while, statistically significant change was observed only in posterior pharyngeal airway space among the chosen cephalometric airway parameters. Conclusion: Treatment with AdvanSyncTM 2 corrected the Class II malocclusion by producing skeletal and dentoalveolar changes. Soft tissue facial convexity and nasolabial angle improved with treatment. Further, linear dimension of the posterior pharyngeal airway space showed significant improvement with AdvanSync 2TM therapy.
