牙槽骨的解剖形态限制着正畸牙齿的移动,了解牙槽骨的形态特点及其影响因素有利于正畸医生制定个性化的矫治方案。不同的骨面型,如矢状骨面型、垂直骨面型等可能影响牙槽骨的形态结构,既往研究从牙槽骨的厚度、高度、面积、颊舌向倾斜度等多方面对牙槽骨的形态做了测量研究,本文就不同骨面型患者的牙槽骨形态研究进展做一综述。The anatomical morphology of alveolar bone restricts the orthodontic tooth movement. Understanding the morphological characteristics of alveolar bone and its influencing factors is helpful for orthodontists to formulate a personalized treatment plan. Different facial skeletal patterns, such as sagittal and vertical skeletal types, may affect the morphological structure of alveolar bone. Previous studies have measured the morphology of alveolar bone in various aspects, including thickness, height, area and buccolingual inclination of alveolar bone. This paper reviews the research progress of alveolar bone morphology in patients with different bone surface types.
本文综述了三维分区量化在正畸治疗中牙根吸收问题的研究现状,包括相关的评估方法、影响因素、研究进展以及未来发展方向,旨在为正畸临床实践和研究提供全面的参考。This article reviews the current research on three-dimensional partition quantification of orthodontic root resorption, including related assessment methods, influencing factors, research progress, and future development directions. The aim is to provide a comprehensive reference for orthodontic clinical practice and research.
推磨牙远移是一种有效的正畸技术,用于解决上颌或下颌牙齿的拥挤问题。通过将磨牙向后移动,可以为前牙创造更多的空间,从而减少拥挤,改善咬合关系。对于有双颌前突的患者,推磨牙远移也可以帮助矫正前突,减少面部突度,改善患者的侧貌。在推磨牙远移的过程中,支抗的作用至关重要。支抗是指在牙齿移动过程中,用来抵抗或控制其他牙齿移动的力量来源。在正畸治疗中,尤其是推磨牙远移时,有效的支抗能够确保目标牙齿按照预期的方向和程度移动,而不会引起不必要的副作用,如其他牙齿的不期望移动、咬合关系的变化等。本文对推磨牙向远中的支抗进行综述,提出各种支抗的不足和临床应用中的限制,为临床应用和技术改进提供参考依据。Molar distalization is an effective orthodontic technique used to solve the crowding problem of maxillary or mandibular teeth. By moving the molars backward, more space can be created for the anterior teeth, thereby reducing crowding and improving the occlusal relationship. For patients with bimaxillary protrusion, molar distalization can also help correct the protrusion, reduce facial protrusion, and improve the patient’s profile. In the process of molar distalization, the role of anchorage is crucial. Anchorage refers to the source of force used to resist or control the movement of other teeth during tooth movement. In orthodontic treatment, especially when molar distalization, effective anchorage can ensure that the target teeth move in the expected direction and degree without causing unnecessary side effects, such as the unexpected movement of other teeth and changes in the occlusal relationship. This article reviews the anchorage for molar distalization, puts forward the shortcomings of various anchorage and the limitations in clinical application, and provides a reference for clinical application and technical improvement.
