Abstract

Extraction spaces may be needed to achieve specific orthodontic goals of positioning the dentition in harmony with the craniofacial complex. However, the fundamental reality that determines the occlusion final position is the control exerted by the orthodontist while closing the extraction spaces. A specific treatment objective may require the posterior teeth to remain in a constant position anteroposteriorly as well as vertically, while the anterior teeth occupy the entire extraction site. Another treatment objective may require the opposite, or any number of intentional alternatives of extraction site closure. The present case report describes a simple controlled segmented mechanic system that permitted definable and predictable force systems to be applied and allowed to predict the treatment outcome with confidence. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) in partial fulfillment of the requirements for Diplomate certification.

摘要

为了实现使牙列与颅面复合体协调定位的特定正畸目标，可能需要拔牙间隙。然而，决定咬合最终位置的基本事实是正畸医生在关闭拔牙间隙时所施加的控制。一个特定的治疗目标可能要求后牙在前后向以及垂直方向保持恒定位置，而前牙占据整个拔牙部位。另一个治疗目标可能要求相反的情况，或者有任何数量的关闭拔牙部位的有意替代方案。本病例报告描述了一种简单的可控分段力学系统，该系统允许应用可定义和可预测的力系统，并能够自信地预测治疗结果。本病例提交给巴西正畸与牙颌面正畸委员会（BBO），以部分满足获得专科医师认证的要求。
