技术领域
本申请涉及医疗器械技术领域，尤其涉及一种调整上下颌位关系的牙科器械。
背景技术
错颌畸形是指在儿童生长发育过程中，由先天的遗传因素或后天的环境因素引起的牙颌畸形现象，后天的环境因素例如是疾病、口腔不良习惯、替牙障碍等，也可以是生长发育过程中的外伤、牙周病等因素。错颌畸形的形成因素和机制是错综复杂的，其发生过程可能由单一因素及单一机制在起作用，也可能是多种因素或多种机制共同作用的结果。
依据安氏分类方法，错颌畸形分为Ⅰ类错合(中性错合)、Ⅱ类错合(远中错合)和Ⅲ类错合(近中错合)。其中，Ⅱ类错合是口腔正畸临床上常见的错合畸形之一，Ⅱ类错合典型的表现为上颌前牙前突、前牙深覆盖、深覆合、开唇露齿、内倾型深覆合、面下部过短或颏唇沟较深等。对于轻中度下颌后缩患者，因为下颌发育不足，患者又处于生长发育期，有些患者甚至是生长发育高峰期，采用功能性矫治器如Twin-Block、肌激动器、Herbst矫治器、功能调节器II型(FR-II)等可刺激、促进下颌的向前生长，对许多II类错颌前牙深覆盖和远中磨牙关系的矫治均能起到很好的作用。
Herbst矫治器是一种针对Ⅱ类错合的固定式咬合前移装置，其机械部分由一对金属套管***组成，分别位于上、下前磨牙和磨牙区颊侧，每侧套管***由一个套管、一个活塞杆、两个枢轴和两个螺丝组成。Herbst矫治器通过每侧两个枢轴被分别焊在位于上颌第一恒磨牙和下颌第一前磨牙颊侧支抗固位体上，然后经螺丝穿过套管和活塞杆末端轴孔将咬合前移装置(即套管和***套管内的插杆)固定于上述支抗固位体上的轴座来完成。矫治器就位后整个套管装置类似于在上、下颌间形成一对人工关节，将下颌保持在前伸位置，开闭口自如，少许侧方运动。但是Herbst矫治器的缺点是下颌运动范围受到一定的限制。
近年来，隐形牙齿矫治器由于其佩戴舒适可摘戴，并且美观，被越来越多的人选择，但是如何将Herbst矫治器的功能矫治效果与隐形矫治器结合并能够达到相同或更佳的矫治效果，或者对隐形矫治器进行结构改进以达到Herbst矫治器相同或更佳的矫治效果， 是丞待解决的问题。
因此研究一种兼顾安全性、舒适性与便捷性的调整上下颌位关系的牙科器械具有重要的意义。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。除非另外定义，此处使用的技术术语或者科学术语应当为本申请所属领域内具有一般技能的人士所理解的通常意义。本文中使用的“包括”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。
针对现有技术存在的问题，参照图1至图13，本申请部分实施例提供了一种牙科器械，用于调整上下颌位关系，具体地说，在牙科器械的作用下，带动下颌向前运动，达到下颌前伸的效果，从而调整上下颌位关系趋于正常。
牙科器械包括容纳上颌牙齿的第一壳状本体10和容纳下颌牙齿的第二壳状本体20，第一壳状本体10和第二壳状本体20分别划分有前牙区和后牙区。其中，“后牙区”根据北京大学医学出版社出版的《口腔医学导论》第2版第36-38页中对于牙齿的分类进行定义，包括前磨牙以及磨牙，以FDI标记法显示为4-8的牙齿，前牙区FDI标记法显示为1-3的牙齿。并且，近中面与远中面为牙冠与邻牙相邻接的两个面，总称邻面。离面部中线较近的一面称为近中面，离面部中线较远的一面，称为远中面。
第一壳状本体10的前牙区可用于容纳上颌牙齿的中切牙、侧切牙和尖牙，第一壳状本体10的后牙区可用于容纳上颌牙齿的第一前磨牙、第二前磨牙、第一磨牙、第二磨牙和第三磨牙，第二壳状本体20的前牙区可用于容纳下颌牙齿的中切牙、侧切牙和尖牙，第二壳状本体20的后牙区可用于容纳下颌牙齿的第一前磨牙、第二前磨牙、第一磨牙、第二磨牙和第三磨牙。
参照图1至图4，分别示出了本申请一实施例的牙科器械的第一壳状本体、第二壳状本体，以及它们咬合前后的示意图。其中第一壳状本体10后牙区的颊侧面向对颌方向 凸出设有调整上下颌位关系的凸起部11，凸起部11具有相对的凸起部近中面111和凸起部远中面112，第二壳状本体20的沿颊侧面向颊侧凸起设有限位部21，限位部21具有相对的限位部近中面211和限位部远中面212，第一壳状本体10与第二壳状本体20相互作用时，带动凸起部11与限位部21相互作用，具体相互作用的方式为凸起部11的凸起部近中面111与限位部21的限位部远中面212相互作用以调整上下颌位关系。
在其中一种实施方式中，所述凸起部11的形成方式为沿第一壳状本体10容纳上颌牙齿的颊侧面向对颌方向延伸形成所述凸起部11，凸起部11的舌侧面可沿第一壳状本体10后牙区牙齿的颊尖处位置向对颌方向延伸。凸起部11包括一作用端，作用端至少部分覆盖第一壳状本体10与第二壳状本体20稳定作用时的第二壳状本体20颊侧面。该种实施方式形成的凸起部11，不仅能够与限位部21相互作用，调整上下颌位关系，还使患者颊侧异物感较小，佩戴更加舒适。
在另一实施方式中，所述凸起部11的形成方式为沿第一壳状本体10容纳上颌牙齿的颊侧面向对颌方向延伸形成凸起部11，凸起部11的颊侧面可凸于第一壳状本体10容纳上颌牙齿的颊侧面，凸起部11的舌侧面可沿第一壳状本体10后牙区牙齿的颊尖处位置向对颌方向延伸。凸起部11包括一作用端，作用端至少部分覆盖第一壳状本体10与第二壳状本体20稳定作用时的第二壳状本体20颊侧面。该种实施方式形成的凸起部11，不仅能够与限位部21相互作用，调整上下颌位关系，在颊舌侧方向的作用面积增大，调节上下颌位关系的稳定性更佳。
如图1-4所示，第一壳状本体10双侧的后牙区颊侧面分别设有一个凸起部11，第二壳状本体20双侧的颊侧面上分别设有一个限位部21，位于同一侧的凸起部11的凸起部近中面111与同一侧的限位部21的限位部远中面212相互作用以调整上下颌位关系，两侧的凸起部11与限位部21分别相互作用，使整个下颌牙列在第二壳状本体20的带动下向前移动，受力均匀，不会引起患者的不适感，也不会带来矫治的其它副作用，如作用不均引起的偏颌。
参照图3和图4，第一壳状本体10与第二壳状本体20相互作用时，第一壳状本体10与第二壳状本体20形成一颌平面，作用端的凸起部近中面111与限位部21的限位部远中面212接触，接触形成的接触面靠近颌平面的一端不高于颌平面。颌平面是指，从双侧上颌中切牙近中邻接点至双侧第一磨牙的近中颊尖顶所构成的虚拟平面。
具体地说，第一壳状本体10与第二壳状本体20稳定作用时，凸起部11的作用端延伸至第二壳状本体20颊侧面，作用端的凸起部近中面111与限位部21的限位部远中面212形成面接触，该面接触的作用面积大，作用力强，且两者的作用面在牙列的颊侧面，能够更好地带动下颌牙列向前运动，达到引导下颌向前的作用，从而调整上下颌位关系趋 于正常，尤其对于spee曲线深度小于3mm的安氏二类病例，具有较好的治疗效果。作用端的凸起部近中面111与限位部21的限位部远中面212接触形成的接触面靠近颌平面的一端不高于颌平面，使得作用面在牙列的颊侧面一端，从而带动整个第二壳状本体使下颌牙列整体向前移动，较现有技术中颊侧或舌侧方分别向对颌方向延伸的效果更佳，现有技术中的颊侧或舌侧方向的两个凸起，两者的接触作用面高于下颌颌平面时，且由于两者在颊侧面相互作用，接触面积较小，作用力分解至使下颌向前方向的力较小，引导效果不佳。
如图5和图6所示，分别示出了本申请一实施例的牙科器械的第一壳状本体、第二壳状本体的示意图。其中第一壳状本体10上可设有多个凸起部11，第二壳状本体20上可设有多个与凸起部11相互作用的限位部21，多个凸起部11与多个限位部21相互作用以诱导调整上下颌位关系趋于正常，多个凸起部11与多个限位部21相互作用，作用力更强，使第一壳状本体10和第二壳状本体20更好地起到调整上下颌位关系趋于正常的作用。
具体地说，如第一壳状本体10上左右两颊侧各设有2个凸起部11，第二壳状本体20上左右两颊侧各设有2个限位部21时，以左侧为例阐述，第一壳状本体10左侧设有前凸起部和后凸起部，第二壳状本体20左侧设有前限位部和后限位部，此时前凸起部设于前限位部和后限位部之间，前凸起部与后限位部可以接触，也可以不接触，当不接触时即前凸起部的远中面与后限位部的近中面不接触，两者存在一定距离；当接触时即前凸起部的远中面与后限位部的近中面接触，两者之间不存在距离。
在其他实施例中，第一壳状本体10双侧的后牙区颊侧面分别设有数量不等的凸起部11(未示出)，对应地，第二壳状本体20双侧的颊侧面上也分别设有数量不等的限位部21(未示出)，该数量不等的凸起部11与数量不等的限位部21相互作用以诱导调整上下颌位关系趋于正常，如该实施例中的数量不等的凸起部11为上颌左右两侧各设置2个，数量不等的限位部21为下颌左右两侧设置3个；或者该实施例中的数量不等的凸起部11左侧设置2个且右侧设置3个，数量不等的限位部21为左侧设置2个且右侧设置3个。
参照图7和图8，分别示出了本申请一实施例的牙科器械的第一壳状本体、第二壳状本体的示意图。其中第一壳状本体10后牙区舌侧面向对颌方向凸出设有调整上下颌位关系的凸起部11，凸起部11具有相对的凸起部近中面111和凸起部远中面112，第二壳状本体20沿舌侧面向舌侧凸起设有限位部21，限位部21具有相对的限位部近中面211和限位部远中面212，第一壳状本体10与第二壳状本体20相互作用时，带动凸起部11与限位部21相互作用，具体相互作用的方式为凸起部11的凸起部近中面111与限位部21的限位部远中面212相互作用以调整上下颌位关系。
在其中一种实施方式中，所述凸起部11的形成方式为沿第一壳状本体容纳上颌牙齿的舌侧面向对颌方向延伸形成所述凸起部11，凸起部11的颊侧面可沿第一壳状本体10 后牙区牙齿的舌尖处位置向对颌方向延伸。凸起部11包括一作用端，作用端至少部分覆盖第一壳状本体10与第二壳状本体20稳定作用时的第二壳状本体20舌侧面。该种实施方式形成的凸起部11，不仅能够与限位部21相互作用，调整上下颌位关系，还使患者颊侧异物感较小，佩戴更加舒适。
在另一种实施方式中，所述凸起部11的形成方式为沿第一壳状本体10容纳上颌牙齿的舌侧面向对颌方向延伸形成凸起部11，凸起部11的舌侧面可凸于第一壳状本体10容纳上颌牙齿的舌侧面，凸起部11的颊侧面可沿第一壳状本体10后牙区牙齿的舌尖处位置向对颌方向延伸。凸起部11包括一作用端，作用端至少部分覆盖第一壳状本体10与第二壳状本体20稳定作用时的第二壳状本体20舌侧面。该种实施方式形成的凸起部11，不仅能够与限位部21相互作用，调整上下颌位关系，在颊舌侧方向的作用面积增大，调节上下颌位关系的稳定性更佳。
如图7和图8所示，第一壳状本体10双侧的后牙区舌侧面分别设有一个凸起部11，第二壳状本体20双侧的舌侧面上分别设有一个限位部21，位于同一侧的凸起部11的凸起部近中面111与同一侧的限位部21的限位部远中面212相互作用以调整上下颌位关系，两侧的凸起部11与限位部21分别相互作用，使整个下颌牙列在第二壳状本体20的带动下向前移动，受力均匀，不会引起患者的不适感，也不会带来矫治的其它副作用，如作用不均引起的偏颌。
在一实施方式中，第一壳状本体10与第二壳状本体20相互作用时，第一壳状本体10与第二壳状本体20形成一颌平面，作用端的凸起部近中面111与限位部21的限位部远中面212接触，接触形成的接触面靠近颌平面的一端不高于颌平面。
具体地说，第一壳状本体10与第二壳状本体20稳定作用时，凸起部11的作用端延伸至第二壳状本体20舌侧面，作用端的凸起部近中面111与限位部21的限位部远中面212形成面接触，该面接触的作用面积大，作用力强，且两者的作用面在牙列的舌侧面，能够更好地带动下颌向前运动，有效地达到导下颌向前的作用，从而调整上下颌位关系趋于正常，尤其对于spee曲线深度小于3mm的安氏二类病例，具有较好的治疗效果。作用端的凸起部近中面111与限位部21的限位部远中面212接触形成的接触面靠近颌平面的一端不高于颌平面，使得作用面在牙列的舌侧面一端，从而带动整个第二壳状本体使下颌牙列整体向前移动，较现有技术中颊侧或舌侧方分别向对颌方向延伸的效果更佳，现有技术中的颊侧或舌侧方向的两个凸起，两者的接触作用面高于下颌颌平面时，且由于两者在颊侧面相互作用，接触面积较小，作用力分解至使下颌向前方向的力较小，引导效果不佳。
本申请一些实施例中，第一壳状本体10与第二壳状本体20相互作用时，凸起部11的作用端的端部低于第二壳状本体20的龈缘端，具体地说，凸起部11自后牙区颊侧面 或后牙区舌侧面向对颌方向凸出的最前端没有延伸到第二壳状本体20的龈缘端，第二壳状本体20的龈缘端是指第二壳状本体20佩戴在患者口内时邻近患者牙龈的一端。第一壳状本体10与第二壳状本体20相互作用时，第一壳状本体10的凸起部11不会接触患者下颌的牙龈，因此能够确保不会伤害患者的牙龈，且佩戴更加舒适。
如图9和图10所示，分别示出了本申请一实施例的牙科器械的第一壳状本体、第二壳状本体的示意图。其中，第一壳状本体10上可设有多个凸起部11，第二壳状本体20上可设有多个与凸起部11相互作用的限位部21，多个凸起部11与多个限位部21相互作用以诱导调整上下颌位关系趋于正常，多个凸起部11与多个限位部21相互作用，作用力更强，使第一壳状本体10和第二壳状本体20更好地起到调整上下颌位关系趋于正常的作用。
具体地说，如第一壳状本体10上左右两舌侧各设有2个凸起部11，第二壳状本体20上左右两舌侧各设有2个限位部21时，以左侧为例阐述，第一壳状本体10左侧设有前凸起部和后凸起部，第二壳状本体20左侧设有前限位部和后限位部，此时前凸起部设于前限位部和后限位部之间，前凸起部与后限位部可以接触，也可以不接触，当不接触时即前凸起部的远中面与后限位部的近中面不接触，两者存在一定距离；当接触时即前凸起部的远中面与后限位部的近中面接触，两者之间不存在距离。
在其他实施例中，第一壳状本体10双侧的后牙区舌侧面分别设有数量不等的凸起部11(未示出)，对应地，第二壳状本体20双侧的舌侧面上也分别设有数量不等的限位部21(未示出)，该数量不等的凸起部11与数量不等的限位部21相互作用以诱导调整上下颌位关系趋于正常，如该实施例中的数量不等的凸起部11为上颌左右两侧各设置2个，数量不等的限位部21为下颌左右两侧设置3个；或者该实施例中的数量不等的凸起部11左侧设置2个且右侧设置3个，数量不等的限位部21为左侧设置2个且右侧设置3个。
本申请一些实施例中，凸起部11沿牙列近远中方向的长度至少部分覆盖后牙区近远中方向牙齿的长度，具体地，凸起部11沿牙列近远中方向的长度至少覆盖后牙区其中一颗牙齿近远中方向的长度。该结构的凸起部11与第一壳状本体10在牙列近远中方向上具有足够的连接强度，在凸起部11的凸起部近中面111与限位部21的限位部远中面212相互作用时，能够防止凸起部11产生形变或位置偏移，确保凸起部11不影响所起的调整上下颌位关系的作用。凸起部11与第一壳状本体10优选为一体成型结构以增强两者之间的连接强度，限位部21与第二壳状本体20优选为一体成型结构以增强两者之间的连接强度。
本申请一些实施例中，凸起部11位于第一壳状本体10对应的第二前磨牙和第一磨牙之间，该位置的凸起部11能够使凸起部11和限位部21更好地起到调整上下颌位关 系的作用，且患者佩戴的舒适性较高。
本申请一些实施例中，如图11a至图11d所示，凸起部11的作用端的凸起部近中面111与限位部21的限位部远中面212分别具有相互作用时增加稳定性的结构。增加稳定性的结构例如为相互作用的平面结构(如图11a所示)、相互作用的曲面结构(如图11b所示)、为凹凸匹配的结构(如图11c所示)、为具有磨砂表面的结构(未示出)、为具有凸点的结构(如图11d所示)、为具有镂空表面的结构(未示出)或为具有孔洞表面的结构(未示出)中的一种、两种或多种的组合。具体地说，作用端的凸起部近中面111与限位部21的限位部远中面212分别具有适配的曲面结构、凹凸结构等。由于第一壳状本体10和第二壳状本体20一般采用高分子材料，作用端的凸起部近中面111与限位部21的限位部远中面212相互作用时容易产生相对滑动的现象，通过增加稳定性的结构，能够减少甚至避免上述相对滑动现象，进而使凸起部11和限位部21更好地起到调整上下颌位关系的作用。
本申请一些实施例中，如图12和图13所示，第二壳状本体20上还设有与限位部21共同作用限制凸起部11相对移动的辅助部22，辅助部22具有相对的辅助部近中面221和辅助部远中面222，辅助部22的辅助部近中面221与凸起部11的凸起部远中面112设有相互作用的接触面以稳定调整后的上下颌位关系；第一壳状本体10与第二壳状本体20相互作用时，凸起部11位于限位部21和辅助部22之间。
具体地说，如图12所示，辅助部22可以由第二壳状本体20沿颊侧面向颊侧凸起形成，辅助部22的结构可与图12中限位部21的结构相同或相似，辅助部22与第二壳状本体20可以是一体成型结构。如图13所示，辅助部22可以由第二壳状本体20沿舌侧面向舌侧凸起形成，辅助部22的结构可与图13中限位部21的结构相同或相似，辅助部22与第二壳状本体20可以是一体成型结构。如图12和图13所示，辅助部22位于限位部21的靠近远中的一侧，在第一壳状本体10与第二壳状本体20相互作用时，限位部21和辅助部22能够卡住位于两者之间的凸起部11，使得咬合关系更加稳定，第一壳状本体10和第二壳状本体20能够更好地起到调整上下颌位关系的作用。
本申请一些实施例中，凸起部11和辅助部22内分别设有诱导调整上下颌位关系且极性相同的磁体(未示出)，在第一壳状本体10与第二壳状本体20相互作用时，凸起部11和辅助部22内极性相同的磁体能够推动凸起部11向近中方向移动或使凸起部11具有向近中方向移动的趋势，进而增加第一壳状本体10和第二壳状本体20导下颌向前的作用。其中，磁体可与凸起部粘结固定或卡接固定，磁体可设于凸起部或辅助部上的相互作用的表面，也可填充于凸起部和辅助部中。
本申请一些实施例中，凸起部11和限位部21内分别设有稳定相对颌位关系且极 性相反的磁体(未示出)，且辅助部22内设有与凸起部11内极性相同的磁体(未示出)，在第一壳状本体10与第二壳状本体20相互作用时，凸起部11和限位部21内极性相反的磁体能够将第一壳状本体10与第二壳状本体20引导至适当位置，凸起部11和辅助部22内极性相同的磁体能够推动凸起部11向近中方向移动或使凸起部11具有向近中方向移动的趋势，进而增加第一壳状本体10和第二壳状本体20导下颌向前的作用。
本申请一些实施例中，凸起部11的刚度大于第一壳状本体10容纳上颌牙齿区域的刚度；限位部21的刚度大于第二壳状本体20容纳下颌牙齿区域的刚度。在第一壳状本体10与第二壳状本体20相互作用时，凸起部11和限位部21相接触以调整上下颌位关系，增加凸起部11和限位部21的刚度，能够防止凸起部11和限位部21发生变形或减少凸起部11和限位部21发生变形的程度，防止影响调整上下颌位关系的作用。
凸起部11与第一壳状本体10容纳上颌牙齿区域的厚度、硬度、材料、层数中至少一种不同，通过改变厚度、硬度、材料、层数中至少一种，使凸起部11的刚度大于第一壳状本体10容纳上颌牙齿区域的刚度。限位部21与第二壳状本体20容纳下颌牙齿区域的厚度、硬度、材料、层数中至少一种不同，通过改变厚度、硬度、材料、层数中至少一种，使限位部21的刚度大于第二壳状本体20容纳下颌牙齿区域的刚度。
本申请一些实施例中，凸起部11和/或限位部21设有填充部(未示出)，填充部可以是可在口内使用的高分子材料，填充部可充满凸起部11、限位部21的空心部分，通过设置填充部，能够防止凸起部11和限位部21发生变形或减少凸起部11和限位部21发生变形的程度，防止影响调整上下颌位关系的作用。
本申请一些实施例中，多组调整上下颌位关系的牙科器械形成牙齿矫治***，该牙齿矫治***包括至少一套如上述任意实施例的调整上下颌位关系的牙科器械，该多组调整上下颌位关系的牙科器械具有使牙齿从初始位置逐渐重新定位至目标矫治位置的几何形状。
本申请一些实施例中，不同的多组调整上下颌位关系的牙科器械上设置的凸起部11向对颌方向的凸起高度随着矫治过程逐渐减小。具体地说，以通过三个矫治阶段对牙齿进行矫治为例，每个阶段使用不同的牙科器械对牙齿进行矫治，如第二矫治阶段所使用的牙科器械为第一矫治阶段后使用的牙科器械，如第三矫治阶段所使用的牙科器械为第二矫治阶段后使用的牙科器械，三个阶段使用的牙科器械的不同之处在于：第二矫治阶段所使用的牙科器械上设置的凸起部11向对颌方向的凸起高度小于第一矫治阶段所使用的牙科器械上设置的凸起部11向对颌方向的凸起高度，第三矫治阶段所使用的牙科器械上设置的凸起部11向对颌方向的凸起高度小于第二矫治阶段所使用的牙科器械上设置的凸起部11向对颌方向的凸起高度。当然，在进行牙齿矫治时，需要患者佩戴一系列的壳状牙科器 械进行矫治，其中一系列的壳状牙科器械的几何形状规律，可参照上述举例。以上描述是进行上下颌间关系的调整方式，在调整颌间关系的同时还可对错颌畸形牙齿进行同步矫治，实现矫形矫治同时进行，一副壳状牙科器械佩戴的时间为7-14天，根据患者不同的病例类型及复杂程度，设置一系列的壳状牙科器械，以达到矫治效果。
虽然在上文中详细说明了本申请的实施方式，但是对于本领域的技术人员来说显而易见的是，能够对这些实施方式进行各种修改和变化。但是，应理解，这种修改和变化都属于权利要求书中的本申请的范围和精神之内。而且，在此说明的本申请可有其它的实施方式，并且可通过多种方式实施或实现。
