制作义齿的一种大变革的方法最近在法国问世,义齿设计和制作的全过程不超过一个小时,不用任何印模和模型材料且不需要手工操作,这在世界上还是首次。义齿的制作分为三个阶段:第一阶段,用一种小型的光学扫描仪在患者口腔的被修复区进行三到五次扫描,显示出连续的图形。这是用一种波纹技术完成的,这种技术可产生一个重叠信号并将此信号译成突出的线的系列,然后进行映象分析。一种特殊的计算机程序产生映象解释显示在电视屏幕上,由Euclid程序联系这些解释可得到修复区三个 One of the most revolutionary ways to make dentures has recently come out in France. The entire denture design and production process took less than an hour, without any impression and model materials and no manual work required, making it the first time in the world. Denture production is divided into three phases: In the first phase, a small optical scanner is used to scan three to five shots in the patient's mouth to show a continuous pattern. This is done with a ripple technique that produces an overlapping signal and translates the signal into a series of prominent lines that are then image-analyzed. A special computer program produces a map interpretation display on a television screen, linked by Euclid programs to these explanations, to obtain three
