相关申请的交叉引用
本申请要求享有于2021年3月26日递交的中国专利申请2021206144863和2021103234909的优先权，它们的全部内容在此通过援引全部并入本文。
技术领域
本申请属于牙齿矫治技术领域，更确切地说涉及无托槽隐形矫治技术领域，尤其指一种牙科矫治辅助装置、壳状牙科矫治器及牙科器械。
背景技术
在牙齿正畸领域，拔牙后产生的牙齿间隙、保持期间出现的拔牙间隙复发、或者其他先天性的牙列间隙是临床医生经常会遇到的问题，在固定牙齿矫治领域，临床上一般会使用直丝弓矫治器矫治法或方丝弓矫治器矫治法来关闭牙齿间隙。方丝弓矫治器是传统的正畸矫治器，其各个牙齿上的托槽都相同，弓丝上必须弯制三种序列弯曲来代偿不同的牙齿形态位置的差异，在临床操作上相对较复杂，弓丝的弯制有时也会因为医生的临床经验的不足产生误差，进而导致治疗效果不佳。直丝弓矫治器是通过托槽底板的结构改进来消除了弓丝的三种序列弯曲，由于每个人的牙齿大小形状扭转情况都存在很大的差异，针对不同的牙齿情况托槽的底板结构也要进行不同的更改，但是针对个体定制托槽会加大矫治成本，不具有普适性。
近些年隐形矫治技术逐渐被大家熟知，由于其隐形美观的特点而受到众多患者喜爱。在现有的隐形矫治中，针对拔牙关闭间隙的病例，隐形矫治器对牙冠进行施力，然后通过牙冠的移动来带动牙根的移动，因此牙根的移动是滞后于牙冠的移动。在牙冠向缺牙处倾斜时，由于隐形矫治器与牙齿之间的摩擦力不够，矫治器还可能会从牙齿上脱落，导致矫治中断。并且隐形矫治器的施力不具备连续性，当隐形矫治器的作用力消减时，可能会出现牙根并没有移动到位的问题，导致矫治失败，还给二次矫正带来了更大的难度。
本申请针对上述问题提供了一种技术改进方案。
发明内容
本申请解决的技术问题是克服现有技术存在的缺陷，提供了一种与壳状牙齿矫治器配合使用用来关闭拔牙间隙的牙科矫治辅助装置，避免或降低了缺失牙毗邻牙向缺失处倾斜的同时增大在矫治过程中壳状牙齿矫治器与牙齿的固位力。本申请还提供了一种与所述牙科矫治辅助装置配合的壳状牙科矫治器及二者配合使用组成的牙科器械。为了实现上述目的，本申请采用的技术方案如下。

在一个实施例中，所述滑动通道与所述导轨间隙配合，且所述间隙配合具有使所述滑动通道沿所述导轨按照预定轨迹滑动的约束，所述约束能够确保装有牙科矫治辅助装置的牙齿不发生不期望的倾斜和转矩。

具体实施方式
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对照附图说明本申请的具体实施方式。显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图，并获得其他的实施方式。
请参阅图1及图2所示，本申请一实施例提供一种包括牙科矫治辅助装置100、壳状牙齿矫治器200以及二者配合使用形成的牙科器械(未标号)，其中，所述牙科矫治辅助装置100，包括基部110、固位部120及滑动通道130，所述基部110包括近牙侧和远牙 侧，所述基部110的近牙侧表面粘接固定在牙齿表面上。在一个示例中，所述牙科矫治辅助装置100按照临床冠长轴对称设置粘贴在牙齿表面；所述固位部120设置在所述基部110的远牙侧的远龈端，所述固位部120由所述基部110向远牙侧凸起形成，所述固位部120和所述基部110为一体成型或两者为分体结构固定为一体，在本实施例中，优选地采用一体成型的结构，所述固位部120至少部分被所述壳状牙科矫治器200包裹以使所述壳状牙科矫治器与牙齿固位；所述滑动通道130设置在所述基部110的近龈端，并且沿近远中方向贯穿所述基部110，所述滑动通道130具有在矫治力的作用下使装有所述牙科矫治辅助装置100的牙齿沿穿过所述滑动通道130的导轨300按照预定轨迹滑动的结构。
在一些实施例中，在牙科矫治辅助装置100不与牙龈接触的前提下，滑动通道130尽量靠近龈缘设置。
在一些实施例中，所述滑动通道130与所述导轨300间隙配合，且所述间隙配合具有使所述滑动通道130沿所述导轨300按照预定轨迹滑动的约束。间隙配合是指滑动通道130的公差带在导轨300的公差带之上，即滑动通道130的实际尺寸永远大于或等于导轨300的实际尺寸，在一个示例中，滑动通道130的实际尺寸略大于导轨300的实际尺寸。换言之，所述滑动通道130沿牙齿长轴方向的截面面积略大于所述导轨300沿牙齿长轴方向的截面面积。在一个示例中，所述滑动通道130与所述导轨300之间的间隙400在0.01mm～0.3mm之间。所述约束是指装有牙科矫治辅助装置100的牙齿在移动过程中，尽量不发生近远中方向上的倾斜或者颊/唇舌方向上的倾斜，所述滑动通道130在导轨300上滑动时，使牙齿按照矫治方案尽可能不发生倾斜或转动的前提下移动至预设位置。
在一些实施例中，所述滑动通道130沿牙齿长轴方向的截面呈圆形或多边形，所述导轨300牙齿长轴方向的截面呈圆形或多边形。所述滑动通道130沿牙齿长轴方向的截面和所述导轨300沿牙齿长轴方向的截面基本一致或不一致。
参考图3a所示，滑动通道130和导轨300沿牙齿长轴方向上的截面基本一致均为圆形，所述滑动通道130与所述导轨300除了在近远中方向上的移动自由度，还有在近远中方向上的转动自由度，其转动自由度可能会造成矫治过程中牙齿发生不期望的转动。
参考图3b所示，滑动通道130和导轨300沿牙齿长轴方向上的截面基本一致均为多边形，所述滑动通道130与所述导轨300具有在近远中方向上的移动自由度，由于多边形具有多个边角，所述滑动通道130和所述导轨300在发生相对运动中，所述导轨300的多个边角结构能够对所述滑动通道130提供转动约束。
参考图3c所示，所述滑动通道130与所述导轨300沿牙齿长轴方向上的截面不一致，所述滑动通道130沿牙齿长轴方向上的截面为圆形，所述导轨300沿牙齿长轴方向上 的截面为矩形，所述滑动通道130与所述导轨300具有在近远中方向上的移动自由度，但是所述滑动通道130与所述导轨300在相对运动中，接触面积过小，导致所述滑动通道130在所述导轨300上滑动时不具有稳定性。在一个示例中，所述滑动通道130和所述导轨300应设置为如图3b中所示，所述滑动通道130与所述导轨300沿牙齿长轴方向上的截面为相同形状不同大小的多边形，使所述滑动通道130在所述导轨300下能够稳定滑动且不易发生不预期的转动，让装有牙科矫治辅助装置100的牙齿能够按照导轨300的预设轨迹移动至预设位置。所述导轨300的材料可为不锈钢、镍钛合金、钴铬合金、玻璃纤维或其他刚性较强的材料，避免导轨300在使用过程发生形变对牙齿的矫治造成影响。
需要阐明的是，本申请中描述的“正畸力”和“矫治力”均表示壳状牙齿矫治器200施加在其包裹的牙齿上的作用力。滑动通道130与导轨300之间的配合产生力不是“正畸力”或“矫治力”，其不对牙齿施加临床上的显著力。导轨300两端固定在不发生移动的牙齿上或牙龈上，导轨300的形态按照矫治方案中牙齿需要移动的路径进行设置。壳状牙齿矫治器200包裹多颗并且将其形变产生的弹性力施加在多颗牙齿上，使装有牙科矫治辅助装置100的牙齿按照导轨300设定的轨迹运动至预设位置，这也就是说牙科矫治辅助装置100的滑动通道130具有在矫治力的作用下使装有所述牙科矫治辅助装置100的牙齿沿穿过所述滑动通道130的导轨300按照预定轨迹滑动的结构。
在一些实施例中，所述滑动通道130与所述固位部120在牙齿长轴方向上呈距离设置，这样的结构可使壳状牙齿矫治器200尽可能的包裹更多的牙齿外表面，提高了临床上壳状牙齿矫治器200对牙齿的控制力，使壳状牙齿矫治器200更好的固定在牙齿上，让壳状牙齿矫治器200和牙齿之间更加贴合和稳固，避免了牙齿与壳状牙齿矫治器200之间摩擦而导致的壳状牙齿矫治器200移动或脱落。所述固位部120的外轮廓形状为圆形、半圆形、多边形中的一种或上述形状的组合中的一种。所述固位部120的外轮廓形状按照临床冠长轴对称设置，使牙科矫治辅助装置100在与壳状牙齿矫治器200配合使用时，不改变壳状牙齿矫治器200对牙齿施加的力的大小和方向。
在另一些实施例中，参考图4和图5，所述基部110在近龈端向远牙侧凸起形成所述滑动通道130的承载体150，所述滑动通道130沿近远中方向贯穿所述承载体150。所述承载体150与所述基部110一体成型或两者为分体结构固定为一体，在一个示例中，所述承载体150与所述基部110是一体成型的结构。所述固位部120与所述承载体150沿牙齿长轴方向呈距离设置。所述固位部120和所述承载体150在牙齿长轴方向之间设有槽沟160。参考图6所示，所述牙科矫治辅助装置100在牙齿长轴上的长度L1设置为3mm～5mm，在一个示例中，长度L1为3.5mm～4mm。所述固位部120在牙齿长轴方向上的长度L2占 所述牙科矫治辅助装置100在牙齿长轴方向上长度L1的20％～50％。具体地，所述固位部120在牙齿长轴上的长度L2设置为0.7mm～2mm，在一个示例中，L2可设置为1mm～1.5mm。所述槽沟160在牙齿长轴方向上的长度L3占所述牙科矫治辅助装置100在牙齿长轴方向上长度L1的20％～40％。具体地，所述槽沟160在牙齿长轴上的长度L3设置为0.7mm～1.6mm，在一个示例中，L3可设置为1mm～1.2mm。所述承载体150在牙齿长轴方向上的长度L4占所述牙科矫治辅助装置100在牙齿长轴方向上长度的20％～50％。具体地，所述承载体150在牙齿长轴上的长度L4设置为0.7mm～2mm，在一个示例中，L4可设置为1mm～1.5mm。
在一些实施例中，所述基部110近龈端设有牵引部140，所述牵引部140由所述基部110在近远中方向上和/或牙齿长轴方向上向外延伸形成，参考图4或图5中的实施例所示，所述牵引部由所述承载体150在近远中方向上和/或牙齿长轴方向上向外延伸形成。参考图6和图7，所述牵引部140在牙齿长轴方向上超过所述牙科矫治辅助装置100近龈端的边缘设置，所述牵引部140在近远中方向上的长度L6大于牙科矫治辅助装置100在近远中方向上的长度L5。所述牵引部140用来与结扎圈或橡皮链配合使用进行颌间/颌内牵引，还可以用来固定牙齿在唇/颊舌侧向的相对位置关系，或使得相邻几颗牙齿紧固为一个整体，当需要多颗牙齿紧固在一起作为整体支抗时也可以使用。
请参见图8和图9，在一实施例中，本申请还提供了一种壳状牙齿矫治器200，与上述任意一个实施例中的牙科矫治辅助装置100配合使用，所述壳状牙齿矫治器200包括容纳多颗牙齿的收纳腔，所述多颗牙齿中有至少两颗牙齿装有所述牙科矫治辅助装置100，所述收纳腔包括收纳所述多颗未安装所述牙科矫治辅助装置100的牙齿的第一收纳腔，和收纳所述多颗安装所述牙科矫治辅助装置100的牙齿的第二收纳腔，所述第二收纳腔至少部分包裹所述固位部120，所述收纳腔具有将所述多颗牙齿从第一位置定位到第二位置的几何结构。当所述牙科矫治辅助装置100如图2中的所示时，所述第二收纳腔包裹至少部分所述固位部120。在一个示例中，所述第二收纳腔包裹所述固位部120的五个外表面。本申请中的所有壳状牙科矫治器的第一收纳腔和/或第二收纳腔能够根据矫治方案被设计成型为：帮助正畸力施加在需要移动的牙齿或牙列上，以便保证在关闭牙齿间隙时，单颗或多颗牙齿能按照期望进行移动。当所述牙科矫治辅助装置100如图4或图5中的所示时，所述第二收纳腔包裹所述固位部120和至少部分槽沟160。在上述的一些实施例中，所述壳状牙科矫治器200与牙科矫治辅助装置上100的固位部120的至少一个表面接触以形成固位力，在一个示例中，所述壳状牙科矫治器200与固位部120近远中的两侧表面接触产生力的作用。此外当所述牙科矫治辅助装置100不与导轨300配合使用，单独作为附件使 用时，可根据矫治需求，将壳状牙科矫治器200与固位部120不同的表面接触以产生所需要的矫治力。
本申请还提供了一种牙科器械，包括壳状牙齿矫治器200及上述任意一个实施例中的牙科矫治辅助装置100，所述壳状牙齿矫治器200包括容纳多颗牙齿的收纳腔，所述多颗牙齿中有至少两颗牙齿装有所述牙科矫治辅助装置100，所述收纳腔包括收纳所述多颗未安装所述牙科矫治辅助装置100的牙齿的第一收纳腔，和收纳所述多颗安装所述牙科矫治辅助装置100的牙齿的第二收纳腔，所述第二收纳腔至少部分包裹所述固位部120，所述收纳腔具有将所述多颗牙齿从第一位置定位到第二位置的几何结构；其中，所述装有所述牙科矫治辅助装置100的牙齿在矫治力的作用下沿所述导轨300按照预定轨迹运动至目标位置。具体地，壳状牙齿矫治器200上的第二收纳腔包裹所述固位部120或所述固位部120和所述槽沟160，使得所述牙科矫治辅助装置100与所述壳状牙齿矫治器200配合使用，其中所述牙科矫治辅助装置100与所述壳状牙齿矫治器200的配合为固位作用，不产生临床上的矫治力，使得矫治过程中的力学系统更加简单，牙齿的移动更符合矫治期望。缺失牙毗邻牙在壳状牙科矫治器200的矫治力下，沿着导轨300的预定轨迹向预定方向运动。
应当说明的是，上述实施例均可根据需要自由组合。以上所述仅是本申请的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
