研究概览
简要总结
the objective of the current study is to compare the dentofacial effects of the mini-plate anchored Herbst appliance Versus the dentally anchored Twin force bite corrector Appliance in Young Adult Class II Orthodontic Patients with retruded mandible.
详细描述
Study design:
Prospective randomized clinical study.
Study setting and population:
This study will be conducted on twenty orthodontic patients. The number of patients was dependent on a power study.
Sample size calculation was based on the observed average effect size derived from previous article addressing "the effect of skeletally anchored Forsus FRD using miniplates for the treatment of Class II malocclusion.

入选标准
- •Participants will be selected based on the following inclusion criteria:
- •Skeletal class 2 malocclusion due to mandibular retrusion with increased overjet (SNA= 82±4, ANB=≥4°).
- •Mandibular arch with minimum (up to 4mm) or no crowding.
- •All permanent teeth are erupted (3rd molar not included).
- •Good oral and general health.
- •No systemic disease or regular medication that could interfere and/or affect orthodontic teeth movement.

排除标准
- •Patients with a blocked-out tooth that will not allow for placement of the bracket at the initial bonding appointment.
- •Patients with untreated decay or any endodontic lesions.
结局指标
主要结局
Amount of changes in dentoskeletal cephalometric measurements between Herbst Group and TFBC group
时间窗: one year and four months
lateral cephalometric radiograph was analysed by dolphin software to assess the following angular (in degree) and linear (in mellimeter) measurements : SNA - SNB - ANB - Y AXIS angle - facial angle - (co - A) - (co - gn) - ( upper 1 - SN) - (lower 1 - MP) - overjet - over bite - soft tissue convexity angle.
次要结局
- Amount of changes in dentoskeletal cephalometric measurements within each group separately(one year and four months)
