Abstract

Maintaining torque with sliding mechanics in maxillary anterior teeth especially in presence of large extraction spaces has become a major concern among orthodontist. Loss of torque occurs owing to play between bracket system and arch wires. Thus, for torque control various arch wire twisting and torquing axillaries have been introduced. Not only do these techniques cause certain discomfort to patients but also extends patient chair time because of various chair side wire bending involved. Thus, a bidimensional technique in bracket system will be beneficial in controlling incisor torque simultaneously it will also assist in loss of anchorage in posterior teeth as it facilitates free sliding of arch wire through the bracket slot thus reducing friction. The aim of this article is to equip an overview of bidimensional technique in orthodontics. Keywords: Bimetric system.

Abstract

One of Major challenges in managing mild to moderate malocclusion cases involves management of class II malocclusion with mandibular deficiencies during active growth period and are generally treated via myofunctional appliance. Dissent of myofunctional appliance led to the evolvement of fixed functional appliance. Power scope appliance is used as a latest class II corrector in day to day practice. This case report describes the efficacy of power scope appliance as a skeletal class II corrector in a male patient aged 14 years with mandibular deficiency who reported to the clinic with chief complaint of forwardly placed teeth.  Levelling and alignment were performed with ideal arch wire sequencing followed by instalment of Power Scope appliance also patient was monitored every month for further adjustment and reactivation of appliance. As a result, Significant changes were seen in mandibular advancement, incisor proclination as well as reduction in over bite and over jet. Anterior movement of soft tissue pogonion lead to notable improvement in facial profile. Keywords: Dental relationship, Different orthodontic and Orthopaedic.
