Class II malocclusions are of interest to practising orthodontists since they constitute a significant percentage of the cases they treat. In individuals with Class II malocclusions, there is an anteroposterior discrepancy between the maxillary and mandibular dentitions, which is usually accompanied by a skeletal discrepancy. In such malocclusions, a functional appliance (myofunctional or fixed functional) is chosen as a treatment method depending on the severity and need of the particular case. This systematic review aims to evaluate the dental-alveolar, skeletal and soft tissue changes with the use of Advansync™ (A Class II corrector/ fixed functional appliance) in the treatment of Class II malocclusion. A literature search was done on Pubmed, EbscoHost , Google Scholar, Science Direct. This was conducted by two reviewers independently and any conflicts in results were managed through discussion. A Risk of Bias was done for the final articles included in the study. A total of 3,099 records were identified while searching through the database based on Mesh terms and search strategies. Based on the inclusion and exclusion criteria’s the total articles which were eligible for the systematic review were six. As the study was specific in terms of age and gender there was a high risk of selection bias but low risk of reporting bias.Out of the 6 studies, 5 had a low risk of bias and based on their cumulative findings, the effectiveness of Advansync is similar to those of other Class II correctors. The advantage of Advansync over other correctors is that the appliance saves treatment time and can be incorporated from the second month of treatment thereby shortening the duration of treatment.Fixed Class II correctors are used widely in Orthodontics. The selection of the appropriate appliance for the patient is the need of the hour. Thus, this systematic review gives us an insight on the use of Advansync in Class II correction.
