项目摘要

We examined the followings :1, The development of tooth crown form (preparation tooth, neighbor tooth, opposite tooth)2, The pilot study for automatically composite resin manufacturing.It was tried to transplanting laser-focus measurement system and 5 axis control displacement gyration table(Kohzu, SA04-03) to our original modeling machine (Roland, CAMM3 PNC-300).In order that weight limit of a measure table and a gyration structure were high prices, attached liaison probe decided to be used as it is. Moreover, in order that built-in controller did transplanting by H8-3039F one board microcomputers(Hitachi), since necessity (piracy of potential) of built in ROM contrary assemblage fitted, a motor driver board of controller built in was done architecture-experimental manufacture newly and it had it to change a schedule and a motor driver board of controller built in substituted on PIX-4 and within it was made.Liaison probe could secure the accuracy that a response enough by active piezo-sensor. By this, measure of tooth crown form came to be able to be performed by equipment on the market by 1 board permutation chisel. It was examined the Adhesion of alumina ceramics and composite resin as a goal formerly at non-metal crown which used a pure aluminal core frame. Tribochemical silica coating (Rocatec, ESPE) was suggested for good bonding strength of alumina and composite.A research result was announced as investigation more than and it was collected as a research result written report.In the future, we will develop the automatically manufacturing system for non-metal crown and fixed denture which consists of hybrid composite and alumna ceramics.

本研究的主要内容如下：1、牙冠形态（预备牙、邻牙、对牙）的开发2、自动化复合树脂制造的初步研究。将激光聚焦测量系统和5轴控制位移回转台（Kohzu，SA 04 -03）移植到我们原来的造型机（罗兰，CAMM 3 PNC-300）上。另外，为了使内置控制器能够移植到H8- 3039 F单板机（日立）上，由于需要，（潜在的盗版）内置在ROM的相反装配中，新做了一个控制器内置电机驱动板的架构实验制造，并在PIX上更换了一个调度和一个控制器内置电机驱动板，采用主动式压电传感器，保证了响应的准确性。至此，市场上的设备只需1板排列凿即可进行牙冠形状的测量。以往以氧化铝陶瓷与复合树脂的粘接性为目标，对纯铝核支架的非金属冠进行了研究。由于氧化铝与复合材料的结合强度好，建议使用摩擦化学二氧化硅涂层（Rocatec，ESPE）。该研究结果被宣布为调查，并被收集为研究结果书面报告。未来，我们将开发由混合复合材料和氧化铝陶瓷组成的非金属冠和固定义齿的自动制造系统。
