Exploring the Distance between Upper Central Incisor Edge and Incisive Papilla in Taiwanese Population
台灣地區上顎正中門齒與門齒乳突距離之探討
摘要
在全口義齒的製作上，門齒乳突是決定上顎前齒位置的一個重要指標。本實驗的目的在找出台灣年輕族群上顎正中門齒、犬齒、門齒乳突三者之間的關係。 本實驗共蒐集81個診斷模型，分別量取門齒乳突正中點到上顎正中門齒唇側面的距離，其結果介於7.18與11.51公釐之間，平均爲9.21公釐；上顎犬齒連線有72.84%會通過門齒乳突的中間三分之一，4.94%會通過門齒乳突的後三分之一，22.22%會通過門齒乳突的中間三分之一與後三分之一交界。本實驗的結果可作爲台灣的牙醫師製作全口義齒、局部活動義齒、覆蓋式義齒及植牙義齒上顎蠟堤時的參考。

Incisive papilla is a significant anatomical landmark in locating upper anterior teeth position in partial or complete and implant prosthetic denture fabrication procedure. The objective of this study is to find the relationship of central incisor and canine to incisive papilla of Taiwanese population. Eighty-one study casts are selected. All selected study casts are analyzed. The distance from the center of incisive papilla to the labial incisal one-third of central incisor is between 7.18 to 11.51 mm, with the mean of 9.21 mm: the line drawn between canines pass middle of the incisive papilla is 72.84%, and pass posterior of the incisive papilla is 4.94%, and 22.22% between middle and posterior of incisive papilla. The result of this study can be used as a guide line in fabrication of the maxillary occlusion rim in Taiwanese population.
