Early prevention and intervention of Class II division 1 in growing patients

Abstract

Early screening and diagnosis help in preventing and intercepting the severity of the malocclusion which helps in addressing the esthetic and functional concerns. Growth modulation such as mandibular advancement has been an effective procedure in orthodontics. Mandibular growth advancer (MGA) and PowerScope are gaining popularity recently as these are effective in achieving the mandibular advancement and ease of fabrication, placement, and wear. MGA was fabricated by making the upper and lower splints separately and are placed in the oral cavity by joining the two splints in the new construction bite using cold cure, MGA when worn during growth phase helps in condylar remodeling in the temporomandibular joint thus helps in advancement of the mandible. The proclination of the upper anteriors in Class II division 1 can be moved lingually by activating the labial bow in the splint. Dr. Andy Hayes worked in conjunction with American orthodontics developed PowerScope. PowerScope delivers Class II correction with a combination of patient comfort and ease of use that was unmatched among other appliances. This ready to use chairside solution required no laboratory setup, making for a much quicker, and easier installation process and appointment. PowerScopes high quality, fixed one-piece design requires no patient compliance. These superior qualities of PowerScope help in correction of Class II skeletal growing patient in conjunction with fixed orthodontic therapy. MGA and PowerScope were chosen as a functional appliance for this study, which shows decreased ANB angle and effective mandible length was increased.

Cephalometric Evaluation of Dentoskeletal and Soft-tissue Changes with Powerscope Class II Corrector

“…No study has yet been documented in the literature which describes the effect of this appliance except for a few case reports. [9,10] The aim of this study was to evaluate the effects produced by PowerScope appliance in skeletal Class II malocclusion using lateral cephalograms.…”

Comparative Evaluation of The Efficacy, Displacements and Stress Distribution Patterns in the Mandible With Two Fixed Functional Appliances: A Finite Element Study.

“…et al16 , Paulose J et al 3 , Keerthi VN. et al17 and Antony T. et al18 showed the forward movement of the mandible with AdvanSync or PowerScope. Forward movement of mandible was observed with AdvanSync 2 (0.669 mm) and PowerScope 2 (0.690 mm) in this finite element study.…”
