摘要

對於植牙手術而言，病患齒槽骨的品質為手術成敗之重要關鍵，其中最困難之部分為上顎後牙區域之鑽削，易發生鼻竇膜受損之情形。鼻竇增高器可防止植牙手術時鑽破鼻竇膜，並幫助上顎後牙區，牙骨高度不足之病患剝離鼻竇膜以利補入骨粉。本研究開發符合各廠植體尺寸之泛用型旋轉式鼻竇增高器，主要內容包括鼻竇增高器設計與製造，並進行實體之測試。
本研究分為三大部分，第一部分為離合機構功能最佳化參數設計，並使用軟體SolidWorks進行工程圖及3D圖繪製。第二部分則將第一部分之工程圖進行GM碼程式編寫，並藉由Star SR-20走心式車銑複合加工機進行製成。第三部分為使用本研究設計之旋轉式鼻竇增高器進行實體測試，測試共分為二階段，第一階段為雞蛋蛋殼鑽削測試，確認旋轉式鼻竇增高器可鑽穿蛋殼，且不致使蛋膜產生破損。第二階段為人工皮質仿骨鑽削測試，確認旋轉式鼻竇增高器可鑽透仿骨，且不致使人工皮膜產生破損，以模擬實際鑽削齒槽骨時之情況。

The alveolar bone quality in the edentulous maxillary posterior area plays a key factor in dental implant surgery. The difficulty of the surgery involves possibility of sinus membrane damage or sinus perforation. A sinus lifting device can help to prevent the defects and elevate the sinus membrane to add graft material in place. This research develops a general sinus lifting instrument which is suitable for implant surgery. The development procedure includes design, manufacture and test.
This research consists of three parts. Part I is the parametric design of the instrument, mainly, a clutch mechanism. The engineering drawings and 3D drawings are completed by using a CAD software, SolidWorks. Part II is the GM codes editing of the engineering drawings. A Swiss-type lathe, Star SR-20, is then used to produce the mechanical parts. Part III is the assembly and test of the sinus lifting instrument. The tests are done in two stages. At the first stage, an egg is used for testing. It is found that the sinus lifting instrument can penetrate the eggshell without damaging the egg membrane. At the second stage of the test, artificial bone by SAWBONE is used. It is found that the sinus lifting instrument can penetrate the artificial bone without damaging the skin film.
