在经过根管治疗的牙根上,做带桩的圆顶形盖,垂直地支持义齿基托,这种装置叫做根支持。由于有根的支持,减少了义齿的扭动力量。有的根支持可能加重根周组织的负担,为了避免出现这种现象,可将根桩的高度减低,甚至低到和龈缘平齐,只用它支持基托,而由其他固位体和基托来固位和抑制水平动度。方法:作者对5名患者进行了这种治疗。在局部义齿上,除了直接固位体外,都采用了牙根来支持义齿的基托,而这些根部都有明显的骨吸收。研究目的:(1)确定有明显骨吸收的根支持对义齿是否能支持得住;(2)这种做法是否有意义;(3)这种根和其他基牙能否互
After root canal treatment of the root, do with the domed dome cover, vertical support denture base, this device is called root support. With rooted support, the force of twisting the denture is reduced. Some root support may exacerbate the burden of root-week organization, in order to avoid this phenomenon, the height of the root pile can be reduced, or even down to the gingival margin, only with it to support the base, and by other retainers and The base restores and restrain horizontal movement. Methods: The authors conducted this treatment in five patients. In the partial denture, in addition to the direct retention of the body, are used to support the root denture base, and these roots have significant bone resorption. The purpose of the study: (1) to determine if there is significant bone resorption of the root support on the denture can support; (2) whether this approach makes sense; (3) whether this kind of root and other abutments
