具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明,本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
结合图1及图2,为本发明一实施方式的带有凸嵴10的牙科正畸矫治器100。
牙科正畸矫治器100包括形成容纳牙齿的空腔S的矫治器本体101,以及连接矫治器本体101的凸嵴10。
凸嵴10朝远离空腔S的方向凸伸出矫治器本体101。
在本实施方式中,通过在矫治器本体101上设置朝远离空腔S的方向凸伸的凸嵴10,可提高整个牙科正畸矫治器100相对于转动轴的惯性矩,该惯性矩可以提高牙科正畸矫治器100在朝远离空腔S的方向上抵抗弯曲的能力,而远离空腔S的方向是牙科正畸矫治器摘取时主要的施力方向,即凸嵴10的设置可提高正畸矫治器100的局部刚度,进而避免牙科正畸矫治器100产生变形或断裂。
另外,本实施方式的牙科正畸矫治器100直接包括凸嵴10,患者直接佩戴牙科正畸矫治器100即可达到上述效果,使用方便,用户体验较佳。
需要说明的是,在利用牙科正畸矫治器100进行矫治的例子中,通常需要把矫治分成多个逐次的阶段(比如20~40个逐次的阶段),每一个阶段对应一个牙科正畸矫治器100,可根据不同阶段的具体需求选择添加或不添加凸嵴10,并可根据不同阶段的具体需求自由设计凸嵴10的添加参数,添加参数包括凸嵴10的数量、位置、形态等。
在本实施方式中,凸嵴10呈条状。
这里,“凸嵴10呈条状”是指凸嵴10在某一方向具有一定长度的延伸,当然,在其他实施方式中,凸嵴10也可以是其他形态,例如为点状等。
在本实施方式中,于远离空腔S的方向X上,凸嵴10具有第一高度,第一高度的最大值范围为0.1mm-10mm。
于凸嵴10的延伸方向Y上,凸嵴10具有第一长度,第一长度大于0.5mm。
这里,凸嵴10的延伸方向Y为近远中方向Y,当然,凸嵴10也可朝向其他方向延伸。
需要说明的是,对应不同的区域,近远中方向Y的实际指向会发生变化,近远中方向Y可以看做是对应凸嵴10的一颗牙齿指向相邻的另一颗牙齿的方向。
于同时垂直于远离空腔S的方向X以及凸嵴10的延伸方向Y的方向Z上,凸嵴10具有第一宽度,第一宽度的最大值范围为0.2mm-8mm。
这里,方向Z为矫治器本体101的颊面A1朝向舌面A2的方向,当然,当方向X和方向Y发生变化时,方向Z也会随之发生变化。
在本实施方式中,于远离空腔S的方向上,凸嵴10的截面的外轮廓为矩形、梯形、弧形、三角形、多边形或“M”形,但不以此为限。
这里,外轮廓是指单个凸嵴10的外轮廓,“M”形是指外轮廓存在一个或多个凹陷,至于凹陷的程度不作限定。
在本实施方式中,凸嵴10包括与空腔S连通的容纳腔S1,且容纳腔S1与矫治器本体101一体成型。
结合图3,可预先在数字牙颌模型200上设计合适的添加件201,添加件201的添加参数与实际所需的凸嵴10的添加参数保持一致。
而后,利用光固化材料制作带有添加件201的牙模,并利用热压膜在牙模上进行热压操作而获得相应的阴模,然后把该阴模多余的部分裁剪去除,最终获得带有凸嵴10(即容纳腔S1)的牙科正畸矫治器100。
需要说明的是,也可通过改变数字牙颌模型200上特定区域的曲率来取代添加件201。
在一具体实施方式中,结合图4,凸嵴10还包括固定于容纳腔S1内的填充部11。
这里,填充部11作为牙科正畸矫治器100的一部分可与容纳腔S1的内壁相互固定,填充部11的设置可提高凸嵴10的强度,且填充部11可为预成型的填充部11,或者,填充部11通过填充及固化工艺直接成型于容纳腔S1内。
在另一具体实施方式中,结合图5,凸嵴10固定于矫治器本体101远离空腔S的一侧表面,即此时取消了如上所述的容纳腔S1,直接将凸嵴10固定于矫治器本体101的外侧表面上。
在本实施方式中,凸嵴10对应待矫治牙齿T的前牙区和/或后牙区设置。
凸嵴10位于矫治器本体101的颊面A1、舌面A2或咬合面A3。
另外,凸嵴10对应待矫治牙齿T的牙齿表面、邻牙间隙P或空泡区的至少其中之一设置。
这里,“牙齿表面”是指每颗待矫治牙齿T的靠近颊面的表面、靠近舌面的表面或咬合面,“邻牙间隙P”是指相邻的两颗待矫治牙齿T之间的区域,“空泡区”是指拔牙区域或者是较大缝隙的区域,“至少其中之一”是指一个凸嵴10可同时覆盖待矫治牙齿T的牙齿表面、邻牙间隙P或空泡区中的一个或多个区域。
凸嵴10可有多种延伸方向,例如,凸嵴10的延伸方向平行于近远中方向Y,或者,凸嵴10的延伸方向垂直于近远中方向Y,又或者,凸嵴10的延伸方向与近远中方向Y之间形成的夹 角为锐角,且凸嵴10呈直线型或曲线型。
牙科正畸矫治器100可包括位于矫治器本体101的一个凸嵴10或多个凸嵴10。
当有多个凸嵴10时,多个凸嵴10间隔分布,或者,多个凸嵴10相互连接。
下面,介绍牙科正畸矫治器100的多种具体示例。
结合图6及图7,牙科正畸矫治器100包括位于后牙区的咬合面A3的两个凸嵴10,两个凸嵴10间隔分布,且两个凸嵴10的延伸方向均平行于近远中方向Y,其中一个凸嵴10靠近颊面A1设置,其中另一凸嵴10靠近舌面A2设置。

结合图10,牙科正畸矫治器100包括位于前牙区的咬合面A3的两个凸嵴10,两个凸嵴10间隔分布,且两个凸嵴10的延伸方向均平行于近远中方向Y,其中一个凸嵴10靠近颊面A1设置,其中另一凸嵴10靠近舌面A2设置。
具体的,凸嵴10主要对应邻牙间隙P设置,且邻牙间隙P对应的是前磨牙和尖牙之间的间隙。
结合图11,牙科正畸矫治器100包括位于前牙区的咬合面A3的一个凸嵴10,且凸嵴10的延伸方向均平行于近远中方向Y。
具体的,凸嵴10主要对应邻牙间隙P设置,且邻牙间隙P对应的是尖牙和切牙之间的间隙。
结合图12及图13,牙科正畸矫治器100包括位于前牙区的颊面A1的一个凸嵴10,且凸嵴10的延伸方向平行于近远中方向Y,凸嵴10主要对应颊面A1的邻牙间隙设置。
这里,当凸嵴10位于颊面A1且凸嵴10的延伸方向平行于近远中方向Y时,为了不影响牙科正畸矫治器100与待矫治牙齿T的整体贴合度,凸嵴10的设置位置不能过于靠近龈端A4。
结合图14及图15,牙科正畸矫治器100包括位于后牙区的颊面A1的一个凸嵴10,且凸嵴10的延伸方向平行于近远中方向Y,凸嵴10对应颊面A1的牙齿表面设置。
结合图16及图17,牙科正畸矫治器100包括位于后牙区的舌面A2的一个凸嵴10,且凸嵴10的延伸方向平行于近远中方向Y,凸嵴10对应舌面A2的牙齿表面设置。
结合图18及图19,牙科正畸矫治器100包括位于后牙区的颊面A1的一个凸嵴10,且凸嵴10的延伸方向垂直于近远中方向Y,凸嵴10对应颊面A1的牙齿表面设置。
结合图20至图22,牙科正畸矫治器100包括位于后牙区的颊面A1的一个凸嵴10,且凸嵴10的延伸方向与近远中方向Y之间形成的夹角为锐角,即此时的凸嵴10倾斜设置,凸嵴10同时覆盖颊面A1的牙齿表面和邻牙间隙P。
结合图23,牙科正畸矫治器100包括位于颊面A1的三个凸嵴10,三个凸嵴10相互连接而形成组合凸嵴10’,组合凸嵴10’主要对应颊面A1的邻牙间隙P设置,且邻牙间隙P对应的是后磨牙与前磨牙之间的间隙。
具体的,组合凸嵴10’大致呈“工”字型,上下两个凸嵴10的延伸方向平行于近远中方向Y,中间一个凸嵴10的延伸方向垂直于近远中方向Y,且组合凸嵴10’包括自由端。
这里,“自由端”是指一个或多个凸嵴10本身的端部未被其他凸嵴10连接,“工”字型凸嵴10的四个端部均为自由端。
结合图24,牙科正畸矫治器100包括位于颊面A1的三个凸嵴10,三个凸嵴10相互连接而形成组合凸嵴10’,组合凸嵴10’主要对应颊面A1的邻牙间隙P设置,且邻牙间隙P对应的是后磨牙与前磨牙之间的间隙。
具体的,组合凸嵴10’的首尾相连而围设形成封闭区域,这里大致围设形成三角形,此时的组合凸嵴10’不存在自由端。
可以理解的是,前述仅是对牙科正畸矫治器100的多种具体示例进行了举例说明,在该些具体示例的基础上做出其他改进而得到的牙科正畸矫治器也包含在本发明的保护范围之内。
下面,针对凸嵴10位于矫治器本体101的咬合面A3的具体实施方式作进一步说明。
结合图25至图28,矫治器本体101的咬合面A3包括对应待矫治牙齿T的邻牙间隙P的过渡区A33,过渡区A33包括凸嵴10,且这里以凸嵴10位于后牙区为例。
这里,邻牙间隙P位于第一牙T1及第二牙T2之间,矫治器本体101的咬合面A3包括分别与第一牙T1及第二牙T2匹配的第一咬合面A31及第二咬合面A32,过渡区A33连接第一咬合面A31及第二咬合面A32。
这里,第一咬合面A31及第二咬合面A32定义为与对颌相互作用的面。
本具体实施方式的过渡区A33包括凸嵴10,凸嵴10靠近邻牙间隙P的内壁12与邻牙间隙P之间形成腔体S2,如此,可提高过渡区A33的惯性矩。
这里,于矫治器本体101的颊面A1朝向舌面A2的方向上,腔体S2的第二宽度的最大值范围为0.5mm-5mm。
结合图29及图30,为现有技术中不存在凸嵴的牙科正畸矫治器300,可以看到,于咬合面301朝向龈端302的方向上,该牙科正畸矫治器300对应邻牙间隙的截面大致呈扁平的弧形,此时,若在龈端302施加方向为M的作用力F,由于此时的惯性矩较小,在作用力F较大的情况下,牙科正畸矫治器300易产生形变或断裂,方向N即为远离空腔S的方向,方向N对应的是摘取牙科正畸矫治器300时的主要施力方向。
而在本具体实施方式中,过渡区A33具有凸嵴10,相当于对图30的虚线框处的区域做了提高加强处理,可增强该处的牙科正畸矫治器100的惯性矩,此时,当在龈端A4同样施加方向为M的作用力F时,牙科正畸矫治器100可避免变形和断裂。
也就是说,本具体实施方式通过在过渡区A33增设凸嵴10,可提高过渡区A33的局部刚度,进而避免牙科正畸矫治器100产生变形或断裂。
在本具体实施方式中,继续结合图25至图27,过渡区A33还包括连接凸嵴10的配合区A34,凸嵴10与邻牙间隙P之间的第一间隙大于配合区A34与邻牙间隙P之间的第二间隙,凸嵴10与配合区A34之间平滑过渡。
也就是说,配合区A34相较于凸嵴10更加靠近邻牙间隙P。
需要说明的是,参图27,邻牙间隙P具体是指第一牙T1靠近第二牙T2的侧面,以及第二牙T2靠近第一牙T1的侧面。
具体的,凸嵴10对应的是过渡区A33做了提高加强处理的区域,配合区A34对应的是过渡区A33未做处理的区域,即过渡区A33包括与邻牙间隙P具有间隙的一部分及紧贴邻牙间隙P的一部分,如此,即可提高过渡区A33的惯性矩,又可避免提高过多区域而影响过渡区A33与邻牙间隙P之间的贴合度。
在本具体实施方式中,凸嵴10的任意区域的厚度大于0.2mm。
具体的,凸嵴10还包括远离邻牙间隙P的外壁13,外壁13与内壁12之间的厚度大于0.2mm。
需要说明的是,在一些实施方式中,凸嵴10的至少两个区域具有不同的厚度,即凸嵴10为厚度变化的结构,但不以此为限。
在本具体实施方式中,继续结合图25至图27,于牙科正畸矫治器100上定义第一截面,第一截面穿过凸嵴10且垂直于近远中方向Y,也就是说,第一截面为如图27所示的A-A方向的剖面。
凸嵴10与第一截面的相交区包括靠近颊面A1或舌面A2的最低点D1、D2,于牙科正畸矫治器100的颊面A1朝向舌面A2的方向(即大致水平方向)上,最低点D1、D2与位于第一截面内的龈端A4之间的间距范围为0.5mm-8mm。
这里,最低点D1、D2对应的是凸嵴10的最末端的点,包括凸嵴10上最靠近颊面A1的第一最低点D1及最靠近舌面A2的第二最低点D2,第一最低点D1及第二最低点D2大致紧贴待矫治牙齿T。
具体的,于牙科正畸矫治器100的颊面A1朝向舌面A2的方向上,第一最低点D1与龈端A4之间具有第一间距L1,第二最低点D2与龈端A4之间具有第二间距L2,第一间距L1及第二间距L2的范围均为0.5mm-4mm。
可选的,第一间距L1及第二间距L2的范围均为1mm-3.5mm。
第一间距L1及第二间距L2为颊面A1朝向舌面A2方向上的间距,通过设置合理的第一间距L1及第二间距L2,可提高牙科正畸矫治器100对待矫治牙齿T的包裹性。
在本具体实施方式中,继续结合图28,于牙科正畸矫治器100上定义第二截面,第二截面穿过凸嵴10且垂直于颊面A1朝向舌面A2的方向,也就是说,第二截面为如图28所示的C-C方向的剖面。
第一咬合面A31与第二截面的相交区包括靠近过渡区A33的第一最高点G1,第二咬合面A32与第二截面的相交区包括靠近过渡区A33的第二最高点G2。
这里,以第二截面穿过第一牙T1及第二牙T2的牙尖点为例,第一最高点G1对应的是第一牙T1靠近第二牙T2的牙尖R1,第二最高点G2对应的是第二牙T2靠近第一牙T1的牙尖R2。
凸嵴10的第一端14与第二截面的交界点为第一交界点J1,第二端15与第二截面的交界点为第二交界点J2。
这里,第一交界点J1及第二交界点J2为凸嵴10于第二截面内的两个端点。
第一最高点G1相较于第一交界点J1远离龈端A4,第二最高点G2相较于第二交界点J2远离龈端A4。
此时,当该牙科正畸矫治器100与对颌咬合接触时,对颌不会接触到凸嵴10,可避免凸嵴10影响正常的咬合过程。
具体的,于牙科正畸矫治器100的咬合面A3朝向龈端A4的方向(即大致竖直方向)上,第一最高点G1与龈端A4之间具有第一距离H1,第一交界点J1与龈端A4之间具有第二距离H2,第二最高点G2与龈端A4之间具有第三距离H3,第二交界点J2与龈端A4之间具有第四距离H4,第二距离H2与第一距离H1的比值不小于20%,第四距离H4与第三距离H3的比值不小于20%。
另外,第二距离H2与第一距离H1的比值不大于95%,第四距离H4与第三距离H3的比值不大于95%。
可选的,第二距离H2为第一距离H1的40%-80%,第四距离H4为第三距离H3的40%-80%。
另外,继续结合图28,在第二截面中,于牙科正畸矫治器100的咬合面A3朝向龈端A4的方向上,牙科正畸矫治器100的任意点与龈端A4之间具有垂直距离,垂直距离在第一最高点G1与第一交界点J1之间逐渐变小,且垂直距离在第二最高点G2与第二交界点J2之间逐渐变小,垂直距离在第一交界点J1与第二交界点J2之间保持不变或呈渐变趋势。
也就是说,矫治器本体101在第一最高点G1至第一交界点J1之间高度逐渐降低,且矫治器本体101在第二最高点G2至第二交界点J2之间高度逐渐降低,矫治器本体101在第一交界点J1与第二交界点J2之间的高度保持不变或呈渐变趋势,如此,可使得凸嵴10在第一咬合面 A31及第二咬合面A32之间平滑过渡。
需要说明的是,第一交界点J1与第二交界点J2之间的垂直距离的变化趋势受到第一牙T1及第二牙T2的具体形态影响,可根据实际情况而定。
在本具体实施方式中,继续结合图25至图28,凸嵴10于其延伸方向上包括相对设置的第一端14及第二端15,第一端14靠近第一咬合面A31,第二端15靠近第二咬合面A32。
这里,凸嵴10的延伸方向平行于近远中方向Y,当然,凸嵴10的延伸方向也可与近远中方向Y之间存在一个较小的夹角。
凸嵴10靠近矫治器本体101的颊面A1、舌面A2设置或居中设置。
具体的,牙科正畸矫治器100包括间隔分布的两个凸嵴10,两个凸嵴10分别靠近颊面A1和舌面A2设置,且两个凸嵴10之间通过配合区A34连接。
其中一个凸嵴10的第一端14及第二端15均靠近颊面A1设置,其中另一个凸嵴10的第一端14及第二端15均靠近舌面A2设置。
可以理解的,在同一个过渡区A33设置两个凸嵴10可进一步提高过渡区A33的惯性矩,进而进一步避免牙科正畸矫治器100发生形变或断裂。
此时,于矫治器本体101的颊面A1朝向舌面A2的方向上,过渡区A33的两个凸嵴10及配合区A34组合形成的轮廓呈“M”型。
具体的,于矫治器本体101的颊面A1朝向舌面A2的方向上,单个凸嵴10的截面为矩形、梯形、弧形、三角形、多边形或“M”形。
结合图31,过渡区A33包括两个凸嵴10,且单个凸嵴10的截面为三角形。
结合图32,过渡区A33包括两个凸嵴10,且单个凸嵴10的截面为矩形。
结合图33,过渡区A33包括两个凸嵴10,且单个凸嵴10的截面为弧形。
结合图34至图36,过渡区A33包括一个凸嵴10,且单个凸嵴10的截面为“M”形。
这里,单个凸嵴10包括凹陷部16及位于凹陷部16两侧的两个突出部17,凹陷部16相较于突出部17靠近邻牙间隙P。
具体的,结合图34,凹陷部16凹陷程度较大,凸嵴10的内壁和外壁大致均为“M”型。
结合图35,相较于图34的凸嵴10,图35的凹陷部16的凹陷程度较小,凸嵴10的外壁大致均为“M”型,内壁大致呈单个“门”字型。
结合图36,相较于图34的凸嵴10,图36的凸嵴10进一步包括靠近颊面A1和舌面A2设置的凹口18。
可以理解的是,在其他具体设计中,凹陷部16及突出部17的数量及位置也可为其他设置形式。
需要说明的是,在其他实施方式中,针对一个凸嵴10,可以是第一端14靠近矫治器本体101的颊面A1设置,第二端15靠近矫治器本体101的舌面A2设置,即凸嵴10于过渡区A33处倾斜设置,凸嵴10的延伸方向与近远中方向Y之间形成的夹角为锐角。
结合图37,可以在咬合面A3的多个邻牙间隙P处形成凸嵴10,进而进一步提高整个牙科正畸矫治器100的惯性矩。
另外,结合图38及图39,第一牙T1与第二牙T2之间包括拔牙区域T3,矫治器本体101包括对应拔牙区域T3的空泡区A5,过渡区A33覆盖空泡区A5。
也就是说,当第一牙T1与第二牙T2之间的邻牙间隙P包括拔牙区域T3时,过渡区A33由第一咬合面A31经过空泡区A5而到达第二咬合面A32,且凸嵴10的延伸区域覆盖空泡区A5。
这里,可通过在空泡区A5设置凸嵴10而提高该区域的惯性矩。
综上所述,本发明通过在矫治器本体101上设置朝远离空腔S的方向凸伸的凸嵴10,可提高整个牙科正畸矫治器100的惯性矩,该惯性矩可以提高牙科正畸矫治器100在朝远离空腔S的方向上抵抗弯曲的能力,而远离空腔S的方向对应的是摘取牙科正畸矫治器时主要的施力方 向,即凸嵴10的设置可提高正畸矫治器100的局部刚度,进而避免牙科正畸矫治器100产生变形或断裂。
另外,本实施方式的牙科正畸矫治器100直接包括凸嵴10,患者直接佩戴牙科正畸矫治器100即可达到上述效果,使用方便,用户体验较佳。
