本实用新型涉及医疗器械的口腔矫正畸技术领域，具体来说，涉及一种乳牙专用托槽。The utility model relates to the technical field of oral orthodontics of medical instruments, in particular to a bracket specially used for deciduous teeth.
背景技术Background technique
托槽是固定矫治的必要工具，以确保矫治力的实施。然而，乳牙的解剖结构与恒牙不同，乳牙体积比同名恒牙要小，颜色较白，牙颈部突出，冠根分明，牙根明显缩小，尤其是乳前牙呈现宽冠窄根的特点，且乳牙牙根较短，在替牙期乳牙牙根吸收后更为短小。目前市面上并没有针对乳牙的专用托槽，将恒牙托槽直接应用于乳牙，会出现托槽体积相对过大、底板不够贴合、患者不适感较强烈、托槽拆除时应力过大加速乳牙松动等问题。Brackets are necessary tools for fixed orthodontic treatment to ensure the implementation of orthodontic force. However, the anatomical structure of deciduous teeth is different from that of permanent teeth. Deciduous teeth are smaller in size and whiter in color than permanent teeth of the same name. They have prominent necks, distinct crowns and roots, and their roots are significantly smaller. In particular, deciduous anterior teeth have the characteristics of wide crowns and narrow roots. The roots of deciduous teeth are shorter, and they become even shorter after the roots of deciduous teeth are absorbed during the tooth replacement period. There are currently no special brackets for deciduous teeth on the market. If permanent tooth brackets are directly applied to deciduous teeth, there will be problems such as the bracket being too large, the base plate not fitting well, the patient feeling more uncomfortable, and excessive stress when the bracket is removed, which accelerates the loosening of the deciduous teeth.
针对相关技术中的问题，目前尚未提出有效地解决方案，因此现有技术还有待发展。Currently, no effective solution has been proposed for the problems in the related technologies, so the existing technologies still need to be developed.
