超音波骨刀在牙科治療上應用探討－臨床報告
Clinical Application of the Piezoelectric Surgery
摘要
近年來因爲人工植牙技術不斷進步，患者對植牙的需求也不斷提升，但是缺乏足夠的骨脊高度及寬度是進行人玉植牙所常面臨的問題。超音波器械在臨床醫學上使用已有一段時間，而在牙周病治療上，超音波結石刮更是佔有不可或缺的重要地位。超音波骨刀因爲具有準確及保護軟組織的臨床特性，經常使用在引導骨再生術及上顎竇增高術治療中，主要因爲傳統器械如骨鋸(bone saw)等，在使用時經常會傷害到周圍的軟組織。但是相對於傳統器械，超音波骨刀仍有所需的手術時間較長的缺點。本文主要介紹超音波骨刀的工具原理、臨床特性及文獻回顧，並提出本院臨床上應用的病例等，爲臨床治療提供工具參考以求提升治療的成功率及安全性。

Ultrasonic instrument has been used in dentistry for a period of time, especially in the treatment of periodontal disease. There are two types of ultrasonic instrument include magnetostrictive units and piezoelectric units. The piezoelectric units produce ultrasonic energy with a crystal system which expands and contracts when an electric current is applied. The characteristics of the piezoelectric units has better effect on the bone surgery than conventional techniques, particularly in surgical contexts in which there is a risk of compromise of adjacent soft tissue. Although the advantages of piezoelectric units have been supported by many studies, the longer surgical time still need to be improved.
