Description

一种个性化舌侧自锁矫治器
技术领域
本发明涉及牙齿矫治器领域，特别是涉及一种舌侧自锁矫治器。
背景技术
随着正畸技术的发展，舌侧正畸被越来越来多的正畸医生认为是正畸技术的发展方向。目前正畸治疗中，普通托槽需要使用结扎丝或橡皮圈来维持弓丝和托槽之间的接触，因而会对弓丝产生较大的压力，使弓丝与槽沟之间的摩擦力增大，妨碍了弓丝的正常移动，影响正畸治疗的效果。同时，结扎丝结扎或橡皮圈结扎，特别在舌侧狭小的空间中，操作难度较大，医师需要花费较多的时间。
目前市面上已有的舌侧自锁托槽主要有三种，一种是二维的自锁功能的简易自锁托槽，其优点是体积小、厚度薄，但是因为无法对牙齿实现三维的控制，因此只能治疗简单的错颌病例；另外一种是与唇侧托槽类似的舌侧托槽，虽然在底板上做了部分改进，使其更贴合舌侧牙面，但是因为是批量制作，所以托槽的整体厚度以及体积仍然很大，严重影响患者的舒适度；另外最近还出现一种个性化底板的舌侧自锁托槽，但是其自锁的托槽体仍然是批量制作，然后焊接在个性化底板之上，因此，并没有完全解决托槽厚度的问题。
并且以上的托槽并没有充分考虑弓丝在舌侧受力与唇侧受力以及唇舌侧矫治过程中的矫治手段的差别，自锁的结构普遍采用与唇侧一致的方式。
发明内容
为解决上述问题，本发明提供一种可有效提高患者舒适度且方便医生临床操作的个性化舌侧自锁矫治器。
本发明解决其技术问题所采用的技术方案是：
一种个性化舌侧自锁矫治器，包括若干舌侧自锁托槽及将各舌侧自锁托槽串接起来的弓丝，各舌侧自锁托槽均包括一与对应牙位舌面吻合的底板及与底板固定连接的托槽本体，托槽本体上铰接有一锁盖，锁盖通过弹性轴铰接在托槽本体上，托槽本体上设有用于卡固锁盖尾端的锁止槽。
进一步作为本发明技术方案的改进，托槽本体上设有联接孔，弹性轴安装于联接孔内，锁盖铰接在弹性轴上，弹性轴为弹性合金轴。
进一步作为本发明技术方案的改进，托槽本体上还设有一弓丝槽沟，弓丝槽沟在闭合后的锁盖下侧。
进一步作为本发明技术方案的改进，锁止槽的上方设有一平行于槽底的水平挡块，水平挡块的顶部还有上翼，托槽本体的底部还设有下翼，下翼的尾端设有一牵引钩。
进一步作为本发明技术方案的改进，托槽本体包括安装于口腔内前牙上的前牙托槽以及安装于后牙上的后牙托槽，各前牙托槽上设有一个上翼及一个下翼，后牙托槽为双翼结构，各后牙托槽上均设有两个上翼和两个下翼。
进一步作为本发明技术方案的改进，锁盖上设有开锁孔。
进一步作为本发明技术方案的改进，锁止槽最底端距离底板的距离小于1mm，上翼的末端以及牵引钩的末端距离底板的距离小于1mm。
进一步作为本发明技术方案的改进，锁盖为弹性金属盖。
进一步作为本发明技术方案的改进，底板的底部设有防滑结构，防滑结构为设置于底板底部的网格。
进一步作为本发明技术方案的改进，底板与托槽本体为一体化制作。
本发明的有益效果：此个性化舌侧自锁矫治器通过弓丝将若干托槽本体串接起来，且托槽本体底部的底板采用柔性金属制作，并在串接过程中通过将锁盖卡入锁止槽内实现各托槽本体位置弓丝的自锁，此自锁矫治器的每个托槽本体位置具有更好的自由性，能有效提高患者的舒适度，同时也方便医生的临床操作。

具体实施方式
参照图1～图4，本发明为一种个性化舌侧自锁矫治器，包括若干舌侧自锁托槽及将各舌侧自锁托槽串接起来的弓丝，各舌侧自锁托槽均包括一与对应牙位舌面吻合的底板1及与底板1固定连接的托槽本体2，托槽本体2上铰接有一锁盖3，锁盖3通过弹性轴221铰接在托槽本体2上，托槽本体2上设有用于卡固锁盖3尾端的锁止槽21。
此个性化舌侧自锁矫治器通过弓丝将若干托槽本体2串接起来，且托槽本体2底部的底板1采用柔性金属制作，并在串接过程中通过将锁盖3卡入锁止槽内实现各托槽本体2位置弓丝的自锁，此自锁矫治器的每个托槽本体2位置具有更好的自由性，能有效提高患者的舒适度，同时也方便医生的临床操作。
作为本发明优选的实施方式，托槽本体2上设有联接孔22，弹性轴221安装于联接孔22内，锁盖3铰接在弹性轴221上，弹性轴221为弹性合金轴。
作为本发明优选的实施方式，托槽本体2上还设有一弓丝槽沟23，弓丝槽沟23在闭合后的锁盖3下侧。
作为本发明优选的实施方式，锁盖3上设有开锁孔31。
作为本发明优选的实施方式，锁止槽21的上方设有一平行于槽底的水平挡块211，水平挡块211的顶部还有上翼24，托槽本体2的底部还设有下翼25，下翼25的尾端设有一牵引钩251。
组成该个性化舌侧自锁矫治器的自锁结构由一个锁盖3、一根能够让锁盖3绕其旋转的弹性轴221以及一个锁止槽21组成，锁盖3上设置了开锁孔31以及联接孔22，弹性轴221为弹性合金轴，由具有高弹性的柔软合金制作而成。
作为本发明优选的实施方式，托槽本体2包括安装于口腔内前牙上的前牙托槽以及安装于后牙上的后牙托槽，各前牙托槽上设有一个上翼24及一个下翼25，后牙托槽为双翼结构，各后牙托槽上均设有两个上翼24和两个下翼25。
当锁盖3末端卡在锁止槽21中时，自锁结构处于闭锁状态时，锁止槽21的上壁处在锁盖3的旋转半径内，于是锁盖3便被限制于锁止槽21中。需要开锁时，给锁盖3施加一个向后的力，此力可以分解为一个水平方向向后的分力和一个垂直于锁止槽21向上的分力，因为弹性轴221具有高弹性，水平分力使得弹性轴221产生弹性形变，锁盖3瞬间水平后移，当锁盖3后移到锁止槽21上壁处在锁盖3旋转半径之外时，垂直分力使得锁盖3旋转出锁止槽21，从而实现开锁动作。开锁动作完成后，弹性轴221在自身弹力作用下恢复到原来的状态，需要闭锁时，将锁盖3绕弹性轴221向锁止槽21方向旋转，当锁盖3被上翼24阻挡住无法再旋动时，此时给锁盖3施加一个垂直于锁止槽21向下的力，上翼24会对锁盖4产生一个水平压力，水平压力使得弹性轴221产生弹性形变，锁盖3水平后移，锁盖3得以继续往锁止槽21方向旋动，当锁盖3完全旋过上翼24时，锁盖3在弹性轴221回弹力的作用下进入锁止槽21，闭锁动作完成。
上翼24和牵引钩251方便个性化舌侧自锁矫治器安装过程中用于牵引。
作为本发明优选的实施方式，锁止槽21最底端距离底板1的距离小于1mm，上翼24的末端以及牵引钩251的末端距离底板1的距离小于1mm。
作为本发明优选的实施方式，锁盖3为弹性金属盖。
锁盖3和底板1均为弹性材料制作而成，有利于增强其柔韧效果，其良好的柔韧性方便在个性化舌侧自锁矫治器安装过程中用于调整。
作为本发明优选的实施方式，底板1的底部设有防滑结构，防滑结构为设置于底板1底部的网格，可防止托槽本体安装完成后滑动。
作为本发明优选的实施方式，底板1与托槽本体2为一体化制作。
此个性化舌侧自锁矫治器可方便医生的操作，个性化的底板1和自锁的结构，节省了医生定位托槽本体2和绑扎弓丝的时间。需要闭锁时，徒手便可完成操作，只要用手指给锁盖3施加一个垂直于锁止槽21槽沟底向下的力便可，需要开锁时，把探针尖端透过开锁孔31伸进开锁槽，往后用力便可将锁盖3打开。
同时，此矫治器的结构简易牢固，不易损坏。其自锁结构的设计适应了最适合舌侧矫治的前牙垂直槽沟，后牙水平槽沟的槽沟系统，并且设置了包括上翼24和下翼25在内的结扎翼，配合了大部分舌侧矫治所必须的各种牵引。同时即使在锁盖3失效的时候，医师也能利用上翼24和下翼25进行结扎丝结扎或橡皮圈结扎。
本发明做到了托槽的完全个性化制作，即托槽本体2以及底板1全部为个性化设计制作，使托槽本体2的厚度降低到最小，使患者的舒适度达到最大。
当然，本发明创造并不局限于上述实施方式，熟悉本领域的技术人员在不违背本发明精神的前提下还可作出等同变形或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
