技术领域 Technical Field

[0001] 本发明属于义齿适合性分析领域,尤其涉及一种可摘局部义齿铸造金属支架适合性的定量评价方法。 [0001] The present invention belongs to the denture fit analysis, and in particular relates to a denture casting metal stents quantitative method for evaluating suitability.

背景技术 Background

[0002] 可摘局部义齿(Removable Partial Denture, RPD)的金属支架传统米用熔模铸造的方法制作,其适合性是评价其制作精度的一个重要指标。 [0002] The removable partial dentures (Removable Partial Denture, RPD) metal stents traditional rice production of investment casting method, which is an important indicator for the evaluation of its production precision. 但由于RPD金属支架的结构复杂,就位后与口腔组织间在三维空间上都存在间隙,因此对其适合性的定量评价是一个难题。 However, due to the complex structure of RPD metal stents, and oral tissue between the three-dimensional space in place after a gap exists, therefore its suitability for quantitative evaluation is a problem.

[0003]目前用于评价可摘局部义齿铸造金属支架适合性的方法有以下几种: [0003] The currently used to evaluate the removable partial denture casting metal stents fit methods are the following:

[0004] 1.就位法:将制作完成的RPD铸造金属支架就位于石膏模型上,然后分别对卡环、牙合支托、连接体等主要部位进行人为观察,进而对其适合性进行主观评价。 [0004] 1. The position of law: the finished cast metal stents RPD is located on the plaster model and are the main parts of the snap ring, occlusal holder, linker, etc. artificial observation, and thus their suitability subjective Evaluation. 一些细微变形不易察觉。 Some slight deformation imperceptible.

[0005] 2.显微镜直接测量法:将制作完成的RPD铸造金属支架就位于石膏模型上,在测量显微镜下对支架与模型间的间隙进行测量,进而评价其适合性。 [0005] 2. microscope direct measurement method: the finished cast metal stents RPD is located on the plaster model at measuring microscope stand and the gap between the models were measured in order to evaluate their suitability.

[0006] 3.切开法:将制作完成的RPD铸造金属支架就位于石膏模型上,然后再将金属支架与模型在同一部位横向切开,在显微镜下对两者间的间隙进行测量,进而评价其适合性。 [0006] 3. incision method: the finished cast metal stents RPD is located on the plaster model, then the model metal stents transverse incision at the same site, under a microscope to measure the gap between the two, and then evaluate their suitability.

[0007] 传统评价方法存在很多弊端。 [0007] There are many disadvantages of the traditional evaluation methods.

[0008] 1.就位法是主观评价法,缺乏有效数据支持,无法定量评价,不客观。 [0008] 1. subjective evaluation method in place, the lack of effective data, no quantitative evaluation, not objective.

[0009] 2.显微镜直接观察法只能对支架局部的适合性进行评价,不够全面。 [0009] 2. The direct microscopic observation can only stand to evaluate the suitability of the local, not comprehensive enough.

[0010] 3.切开法需要破坏模型和支架,在切开的过程中可能会造成模型的破损及支架的变形,影响测量的准确性,并且只能对局部进行测量,不够全面。 [0010] 3. The incision needs failure model and bracket, the cutting process can cause damage and deformation of the stent model, affect measurement accuracy, and can only be measured locally, is not comprehensive enough.
