Comparison of Dental and Soft Tissue Paramaters after Orthodontic Treatment with Mini Screw Implants and Traditional Anchorage in Patients with class I Bimaxxilary Protrusion -A Retrospective Cephalometric Study..

Abstract

Introduction: Satisfactory orthodontic treatment outcomes and better smile appearance have attracted large number of adolescents and adults to seek orthodontic treatment. The present trend to treat bimaxillary protrusion is extraction of the 4 first premolars, followed by anterior tooth retraction to obtain the desired dental and soft- tissue profile changes. Anchorage design as a fundamental part in orthodontic treatment planning will influence the ultimate therapeutic effect including dental, skeletal and soft tissue changes. In clinical practice, orthodontists’ concern is which anchorage type - traditional anchorage or the implant would be more effective.

Therefore, this study was undertaken: • To evaluate soft tissue parameters after orthodontic treatment with mini screw implants in class I bimaxillary protrusion patients. • To evaluate dental parameters after orthodontic treatment with mini screw implants in class I bimaxillary protrusion patients. • To evaluate soft tissue parameters after orthodontic treatment with traditional anchorage in class I bimaxillary protrusion patients. • To evaluate dental parameters after orthodontic treatment with traditional anchorage in class I bimaxillary protrusion patients. • To compare dental and soft tissue parameters among the patients treated with mini screw implants and with traditional anchorage in class I bimaxillary protrusion patients.
