Management of Skeletal Class-II Malocclusion Using Advansync 2: A Case Series

Abstract

Angle’s class II division 1 malocclusion, being the most commonly occuring type of malocclusion, is
challenging to treat especially when there is an underlying skeletal discrepancy. Various fixed functional
appliances have been developed over the years by different authors for correction of skeletal class II
malocclusion due to retrognathic mandible. Among the fixed functional appliances available for class II
correction, Advansync2 (Ormco Co, Glendora, Calif) also known as molar to molar appliance has been used
effectively in the recent past. It is a fixed tooth-born functional appliance with an advantage of allowing
concurrent use of fixed orthodontic therapy. This facilitates reduction of the overall treatment duration. Two
case reports of patients treated using the Advansync2 class II corrector has been presented along with the
skeletal and dentoalveolar changes observed during the treatment. The effects observed were similar to most
fixed functional appliances however the treatment duration was considerably reduced in all the cases.
