Abstract
This report illustrates the successful nonsurgical and nonprosthetic camouflage treatment of a skeletal Class II open bite malocclusion combined with missing mandibular first molars bilaterally. In the mandible, the second and third molars were uprighted and protracted, substituting for the missing first molars. In the maxilla, anterior bodily retraction and full-arch intrusion were achieved following premolar and second molar extraction, which also induced autorotation of the mandible. The treatment outcome and prognosis were confirmed with three-dimensional superimposition techniques, along with long-term stability.
摘要
本报告说明了一例成功的非手术、非修复性伪装治疗，用于矫正双侧下颌双侧第一磨牙缺失的骨性 II 类开𬌗畸形。在下颌，通过直立和远中牵引第二和第三磨牙，替代缺失的第一磨牙。在上颌，通过拔除前磨牙和第二磨牙实现了前牙整体后移和全牙弓内陷，这也诱导了下颌的自动旋转。通过三维重叠技术以及长期稳定性来确认治疗效果和预后。
