Description
本发明涉及用于固定一个假体(尤其是一个假牙)的磁铁装置,其中一个磁铁植入或固定于一个植入物,而另一个相对的磁铁安置在一个假体中。
在这种类型的磁铁装置中,当固定在假体中的磁铁相对于植入磁铁移动时为了获得自对中作用(self-centering action),例如在咀嚼运动中,一个磁铁的表面呈凸形,而另一个相对的磁铁的表面相应地呈凹形。在咀嚼运动中,当假体相对于植入磁铁有些移动时,安置在假体中的磁铁产生一个相应的位移,因此一旦作用于假体的力消失,受磁力的作用安置在假体的磁铁就会自动恢复到对准位置。
此外,通过本发明,提出了一种将一个磁铁定位于一个假体中的装置,通过该装置要安装在一个假牙中的磁铁可以与一个已植入的磁铁精确对准地安位。
本发明的有益设计限定在以下的描述和权利要求书中。
通过举例的方式,下面参照附图更详细地说明本发明的实施例,其中:
图1显示了两个相互邻接的圆柱形磁铁的纵剖面,
图2显示了与定位装置连接的两个磁铁的剖面,
图3显示了定位装置的剖面。
图1以纵剖面图形式显示了一个圆柱形磁铁2和一个相对的圆柱形磁铁3,磁铁2植入或固定于一个植入物,而磁铁3固定在一个假体中(未示出)。与圆柱形磁铁2的纵轴垂直的端面10在边缘区域9是圆形的,以使得凸球环形的表面9有一个从圆柱形磁铁的轴开始的半径R。
磁铁3的相对的端面11具有相同的球半径R的连续的凹形,因此两个相互邻接的磁铁2和3只在边缘区域9相互支承,而在平端面10的中间区域在两个相对表面之间有一个间隙。这样,当支撑假体时避免了在磁铁的中心的一个压力点,并且当由于假体的位移运动使设置在假体中的磁铁3相对于植入磁铁2弯曲时,基于相互支承而产生了磁铁2与3的自对中作用。
植入磁铁2也可以具有连续的凸球形表面9、10,但当磁铁3弯曲运动时会导致磁铁3更显著地高于磁铁2,当例如磁铁3横向移向装置的轴时。使表面部分10平坦的结果,致使当磁铁3横向移向轴时磁铁3不会显著地隆起。
图2显示了一个磁铁装置,它具有分别焊接在盒12内的磁铁2和3,凹表面11和球环形表面9成形在相应的盒12的相对的表面上。在1处,示意地显示了一个牙植入物的头部,其中在该处植入物插入具有盒12的圆柱形磁铁2。为了更容易地将磁铁3精确地定位在一个假牙(未示出)中,设置了一个轴套形件4,它可以由一种医疗领域中许可的软硅酮材料制成。轴套形件4有轴套体8,在其下部有一个相应于植入磁铁2,12的外径的内径,从而能够安装轴套体8。在其内表面上,轴套体8有一个具有预定厚度的隔板5,该隔板一方面限制植入磁铁2,12在轴套体8中的插入深度,另一方面用作从上插入轴套体8的磁铁3,12的隔片。因此轴套体8的上部具有一个相应于磁铁3,12的外径的内径。隔板5在两个磁铁之间产生一个限定的空隙,该空隙平衡了由于咀嚼运动的结果受假牙挤压的颌粘膜的不同的弹性。
轴套体8在其上部具有大约1毫米的壁厚,向下方增加到大约2毫米,从而产生轴套体8的截头图锥体形的外表面,从轴套体8的下边沿径向向外延伸的是一个盖凸缘6,它可以具有例如16毫米的外径。这个凸缘6用于覆盖粘膜并且牙科医生可以根据相应的颌的比例将该凸缘切削到应有的尺寸。为了更容易地将件4安装在植入磁铁2,12上,在7处斜切轴套体8的下开口。
当安装磁铁夹持器时,先将下磁铁2,12旋入植入物,随后将软硅酮件4安装在磁铁2,12上。凸缘6覆盖粘膜并且轴套体8的较厚的下部紧密地封闭磁铁2,12。隔板5主要上支承在球形表面9上。为此,如图3所示,隔板5呈某种向上拱起的形状成形的轴套体上。然后上磁铁3压入轴套体直至受到隔板5的阻止。轴套体8的上边缘与隔板5之间的距离设计成使磁铁3,12从轴套体8突出一个预定的量,例如1.5毫米。通过这个露出的保持表面,上磁铁3,12插入假牙(未出示)的预制的凹座中。于是磁铁3,12通过液体自聚合产物靠聚合作用插入假体中。具有盖凸6和隔板5的轴套体8防止了液体自聚合产物浸湿磁铁2,12和植入物。
一旦聚合产物变硬,就可以去除件4。由于轴套体8的锥形形状的结果,在假牙的底部与植入物或磁铁2,12的顶部之间形成一个预定的空腔,该空腔延伸进入口腔,因此,即使发生假牙横向向纵轴的位移运动,假牙的底部也不会支撑在磁铁2,12上。因此防止了假体的任何损坏,并且对植入物具有有害效应的不希望的水平推力不会从假体传递到牢固地固定在骨中的植入物。
在示意表示的实施例中的件4的整个高度例如可以是3.7毫米。其内径是4.4毫米。隔板5可以设计成具有不同的厚度以使两个磁铁之间的空隙能适合于口腔粘膜的不同弹性。也可以有这样一个实施例,其中省去了隔板5,例如在末端牙冠的情况下。在这种情况下,如图1所示,两个磁铁可以直接相互支承,并通过轴套体8对其相互对中。
代替隔板5,在轴套体8上也可以形成径向向内突出的凸片作为隔片。最好设置一个封闭的隔板5以防止液体聚合产物的渗透。
根据图1,件4不仅可以用于对中磁铁装置,也可以用于其它磁铁对,其中两个磁铁相互相对地沿着一个垂直于纵轴的平端面设置。
