碩士 === 崑山科技大學 === 機械工程研究所 === 91 === The manufacture procedures of traditional dental restorations include many artificial steps. Each step will cause many errors that lead to different sizes of dental restorations from the original design and make patients have abnormal occlusions or insufficient contact. By the dentists’ clinical experience, investing among all of the manufacture procedures of the restorations will make the wax pattern deformed because of thermal expansion. It will cause greatest error of the manufacture procedure of the restorations. In the dental treatment territory, a lot of traditional auxiliary instruments are used, but there is few instruments integrating computer assisting technique and automatic equipments. This research method is using computer aided technique and automatic equipment in clinical treatment to advance diagnosis procedure, shorten treatment duration, and let patients have more comfortable occlusions. In addition, there’s no system that measures the shape and pressure of the consumer’s feet in the past. The consumer chooses insoles and footwear only by trying the shoes. It is hard to be controlled. Besides, discomfort of wearing often results in foot diseases. Furthermore, there is no system which records consumer’s foot information. On the basis of needs above-mentioned, this research developed one system of digital image measuring foot shape and pressure, that gets foot image by high-resolution scan system and measures length and width of foot to pick up idoneous size of shoes and calculates bearing pressure of every part of foot. So we can operate in coordination with adjustable multi-gasbag insoles to get personal insoles, and help factories to fabricate shoes products with better comfort and structure.
