Comparison of Dental Effects of Forsus Fatigue Resistant Device and Powerscope Treatment – A Cephalometric Study

Abstract

Objectives- To evaluate and compare the dentoalveolar effects of Forsus Fatigue Resistant Device and Powerscope Class II Corrector.

Materials and method- Lateral cephalograms of 48 (pre-treatment and post treatment) class II patients in the post peak age group were taken and divided into three groups according to the treatment administered for correcting class II malocclusion with retrognathic mandible . 12 patients were treated as control group, 12 treated with Forsus Fatigue Resistant Device and 12 treated with Powerscope Class II Corrector. The dental analysis was done using Pancherz cephalometric analysis.

Results- Cephalometric analysis revealed that in both the appliances, maxillary central incisors were extruded, retruded, and distally tipped. Contrarily, intrusion, protrusion, and labial tipping were observed in the mandibular central incisors. Distal movement and intrusion of the maxillary first molars and mesial movement and extrusion of the mandibular first molars were the other dental alterations. Overjet and overbite decreased, and a Class I molar relationship were attained in both treatment groups.

Conclusion- Both the appliances were effective in the treatment of Class II malocclusion and revealed nearly same alterations in the dental parameters.
