摘要

傳統牙科補綴物的製作程序中，包含釵h以人工為主的操作步驟，每一項步驟均會產生誤差，導致所製作出來的補綴物與原先的設計尺寸不同，造成病患上下顎咬合狀態不當，或是密合度不足。經由醫師的臨床經驗指出，在補綴物的所有製作程序中，包埋過程會因為熱膨脹的原因造成臘模變形誤差，而此項誤差為製作補綴物產生最大誤差的主要原因之一。然而在牙科的治療領域中，醫師使用到相當多的傳統輔助器械，但卻少有結合電腦輔助技術與自動化的儀器設備，本研究係將電腦輔助工程技術與自動化器械運用於診療過程中，以利於精進診斷過程，縮短治療時程，使得病人牙齒嚙合時感到更舒適。
另外，過去並沒有一套系統是針對一般消費者的腳形、腳壓作量測分析，純粹是以試穿比對來選購鞋墊、鞋類，這除難以控制外，往往會因穿著不舒適而造成足部病變，而且也沒有一套系統可以用來記錄消費者的足部資料。基於以上的需求，本研究另外開發一套數位影像腳形、腳壓量測系統，利用高解析度之掃描系統擷取腳形之影像，經過自行撰寫影像處理程式，快速的將足底長、足底寬及適用鞋號定出並計算出個人腳底各部之承受壓力，配合可調式多氣囊鞋墊得到個人鞋墊，並協助廠商製出舒適性與結構性更好的鞋類製品。

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.
