Description

美白牙托 技术领域
本发明涉及一种牙科用具，具体来说涉及一种美白牙托。
背景技术
随着生活水平的提高，人们日益重视牙齿的美白和健康。并发展出了多种美白牙齿的手段。最基础的牙齿美白为物理洁牙，需要到口腔医院去定期洗牙。而洗牙无法改变牙齿的原始基色，只能做到单纯祛除牙齿表面的牙垢和牙结石。近年来，牙科业出现一种美白牙托，其工作原理是首先根据用户的牙齿形状制备出形状对应的牙托，随后将美白剂挤入牙托底部，然后用户将牙托套上牙齿，使牙齿表面与美白剂相接触、美白剂的气体在分解过程中通过化学反应去除沉积在牙齿表面和/或内部的着色分子，可以改变外源性染色，有些还能改变内在化过程的染色以及内源性着色，从而达到美白的功效。这种美白牙托的优势在于操作简单、不但可以在口腔医院现场使用，也可以由用户在其他场所自行操作使用。但其存在以下缺陷：现有美白剂的结构导致用户在自行使用时很难掌控挤入牙托内的美白剂用量、经常对牙托过量挤入美白剂造成对美白剂的浪费。而美白剂本身具有一定的流动性。当牙托内存在过量美白剂时、在牙齿进入牙托的过程中会将美白剂推挤到牙龈、因牙本质暴露而产生的牙齿敏感区(以下简称牙齿敏感区)和其它口腔内软组织处，美白剂与软组织的持续挤压接触会产生一定程度的刺激和灼伤，而美白剂与牙齿敏感区的接触则会导致牙齿面的不适反应。此外，传统结构的美白牙托在使用时，美白剂不可避免地同时与牙齿的唇侧面、舌侧面和咬合面相接触。无法针对需要进行美白的区域进行针对性美白。导致即使美白剂没有过量挤入牙托，也会有部分美白剂被浪费在无需进行美白的牙齿面。因此，如何开发出一种新型的美白牙托，能够克服上述问题，实现保护牙龈软组织、牙齿敏感区域和其他口腔软组织。高效利用和节约美白剂的作用，是本领域技术人员需要研究的方向。
发明内容
本发明提供了一种美白牙托，能够根据实际需要对牙齿的指定区域进行针对性美白，在保证美白效果的同时节约美白剂的用量，并有效避免美白剂对牙齿敏感区域、牙龈及其他口腔软组织的刺激和灼伤。
其采用的具体技术方案如下：
一种美白牙托，包括牙托本体，所述牙托本体顶部开口，包括依次连接的唇侧部、咬合部和舌侧部；所述唇侧部和舌侧部表面分别设有与牙齿形状吻合的凹槽。其中，在所述咬合部、唇侧部和舌侧部的至少一面上设有存储腔。
通过采用这种技术方案：在进行美白的过程中，通过将美白剂预先注入存储腔中。当牙齿咬入美白牙托时。存储腔中的美白剂挥发、与其所正对的牙齿面接触，对牙齿各个面实现针对性的美白。更能够避免由于用户在美白牙托中注入过多的美白剂而对牙龈及口腔内其他软组织造成刺激和灼伤。此外，在针对唇侧部或舌侧部需要美白的牙齿，传统的美白方法无法单独针对性地对唇侧部和/或舌侧部进行处理或美白、而采用本产品可以针对性地进行舌侧和或纯侧美白，同时大幅提高了针对唇侧部或舌侧部牙齿美白时美白剂的使用效率。
优选的是，上述美白牙托中：所述存储腔为窄口腔体。
之所以采用这种技术方案：是考虑到美白剂具有一定的流动性。当存储腔设置在美白牙托的唇侧部或舌侧部时，美白剂有可能从存储腔中流到美白牙托的咬合部，而通过将存储腔的口部设为窄口结构。可以减少注入存储腔内的美白剂与外部的接触面，利用美白剂的表面张力使美白剂保持停留在存储腔内。避免美白剂在重力作用下从唇侧部和/或舌侧部上流到咬合部上，避免不必要的接触。
更优选的是，上述美白牙托中：所述存储腔的容积为0.26mm^3至56.54mm^3。
采用这种技术方案：是为了兼顾考虑美白剂的流动性和美白剂用量对牙齿面的美白效果，经过大量实验发现：当存储腔的容积过小时，注入的美白剂不足以很好的完成齿面美白。而当存储腔的容积过大时，一方面会造成美白剂的浪费，且容易造成存储腔中的美白剂过量而增加流动性漏出。
进一步优选的是，上述美白牙托中：还包括密封线，所述密封线设于唇侧部和/或舌侧部上、用于将存储腔与牙齿唇侧面和/或舌侧面的牙龈沿、牙齿敏感区及口腔内其他软组织分隔开。
通过采用这种技术方案：以密封线实现对美白剂的封锁，进一步避免美白剂在美白过程中因其他不当操作到达靠近唇侧部和/或舌侧部的牙龈及软组织以及牙齿敏感区域，造成刺激和灼伤。
更进一步优选的是，上述美白牙托中：还包括牙龈延伸部；所述牙龈延伸部连接在唇侧部和/或舌侧部的牙龈侧边沿上。
通过采用这种技术方案：当牙齿进入时、牙龈延伸部贴合在唇侧牙龈和/或舌侧牙龈上，这种结构有利于防止美白剂在挥发过程中从牙托唇侧部和/或舌侧部的牙龈侧边沿溢 出，避免美白剂的浪费和削弱美白效果，同时增加了佩戴舒适性。
再进一步优选的是，上述美白牙托中：所述牙托本体采用硬质材料制成。
通过采用这种技术方案：使得牙托本体在套接于牙齿上时对牙齿产生一定的应力，在美白的过程中实现对齿面的矫正效果。使得本产品的功能更加多元化。
又进一步优选的是，上述美白牙托中：所述牙托本体采用硬质弹性材料制成。
之所以采用这种技术方案：在于采用纯粹的硬质材料构成牙托虽然可以实现矫正功能，但是普通用户在使用时容易施力不当而造成牙托的折断，采用硬质弹性材料可以有效避免牙托的这种折断的情况。
与现有技术相比，本发明通过设置存储腔的结构避免用量的失控和错误的凝胶挤放位置，同时通过设置密封线结构避免凝胶外漏。能够对牙齿的指定区域进行针对性美白，在保证美白效果的同时节约美白剂的用量，有效避免对牙龈软组织的刺激和灼伤。
附图说明
下面结合附图与具体实施方式对本发明作进一步详细的说明：
图1为本发明实施例1的主视示意图；
图2为本发明实施例1的俯视示意图；
图3为本发明实施例2的主视示意图；
图4为本发明实施例3的主视示意图；
图5为各实施例中存储腔的剖面示意图；
各附图标记与部件名称对应关系如下：
1、牙托本体；11、咬合部；12、唇侧部；13、舌侧部；14、存储腔；15、密封线；16、牙龈延伸部。
具体实施方式
为了更清楚地说明本发明的技术方案，下面将结合各个实施例作进一步描述。
图1、2、5所示为实施例1：
一种美白牙托，包括牙托本体1，所述牙托本体1顶部开口，包括依次连接的唇侧部12、咬合部11和舌侧部13。所述唇侧部12和舌侧部13表面分别设有与牙齿形状吻合的凹槽；还包括存储腔14。在本例中，所述存储腔14设于唇侧部12上。其4整体呈半球形。实践中也可以采用除半球形意外的其他形状、其采用窄口腔体；所述存储腔14的容 积为0.26mm^3至56.54mm^3。所述牙托本体1采用硬质弹性材料制成。
实践中，其工作过程如下：通过将美白剂预先注入存储腔中。当用户以牙齿咬入美白牙托1时。存储腔14中的美白剂分解挥发、与其所正对的牙齿唇侧部接触，对用户的牙齿唇侧部实现针对性的美白。实践中，若舌侧部13或咬合部11需要美白，同样可以把存储腔14设置在舌侧部13或咬合部11上，其美白工作过程同上。
图3，5所示为实施例2。
实施例2与实施例1相比，进一步公开了密封线15的特征。在本例中，所述密封线15设于唇侧部12上、将存储腔14与唇侧部12的牙龈及部分牙齿敏感部位如牙颈部分隔开。
