局部義齒病患之後縮舌位置
The Retracted Tongue Position among Posterior Partially Edentulous Patients
摘要
老人義齒的使用率已經相當的普遍，如何製作出一副實用性高的義齒則變得很重要。一副成功的假牙必須同時存在固位(retention)、穩定(stability)及支持(support) 三個重要的因素。而舌位置對於義齒的穩定性來說，佔了非常重要的因素，假若舌位置習慣性的呈現在退縮(retraction)的位置，義齒的穩定性則不佳。但這項因素卻顯少為臨床牙醫師所重視，因此引發本研究動機。本研究以45歲以上且製戴局部活動義齒者為對象，採用問卷調查及口腔檢查法，了解局部義齒之裝戴者，其舌位置的分類情況及義齒穩定性之關係。本研究之有效檢查及問卷包括製戴局部活動義齒者65份，自然牙者86份，共151份。製戴局部義齒者，平均年齡60.68±9.92歲，有36位(55.39%)有後縮舌位置；自然牙部份，平均年齡68.78±9.10歲，有9位(10.35%)有後縮舌位置。本研究調查所得結果，後縮舌位置在臨床上佔有一定比例的人口，而後縮舌位置會影響義齒的穩定性；因此，希望本研究可以提供臨床牙醫師在製做義齒時，另一項重要的參考數據。

As elderly edentulous patient has become popular universally, how to make a set of highly practical and usable denture becomes very imperative. A good denture should include three essential factors: retention, stability and support. Regarding to the stability, the tongue position is accounted one important factor. If the tongue remains at retracted position habitually, the stability of the denture will be poor. However, the particular fact has been neglected by many dental practitioners. This research was carrried out by questionnaire and intraoral examination, and the sampling was to focus on the people, at age of over 45, who wear the removable partial denture. This study proceeded with 151 valid survey including 65 removable partial denture wearer and 85 cases with natural dentition . Partial denture wearer was with average age of 60.68±9.92, and 36 cases (55.39%) have the tongue position retracted. On the other hand, the participants with natural dentition was with average age of 68.78±9.10, and only 9 cases (10.35%) have retracted tongue. With this result, we know that the retracted tongue is more popular in RPD wearer than natural dentition and has some effect to the stability of the denture, hence this study will be a useful reference for the dental practitioners during the treatment of the removable partial denture.
