中文摘要 | 補綴物製作時,門齒乳突經常作為上顎前牙位置之重要參考。本研究之目的在探討國人青年群正常齒顎者其門齒乳突和上顎前牙之關係位置。以 100 位正常齒顎關係者 (男 50 位,女 50 位,平均年齡 22.4 歲) 齒列模型為樣本,本實驗利用三次元精密測量儀器測量門齒乳突與上顎前牙相對位置。所得之數據以 SAS 程式作統計與相關性分析,以探討性別間的差異及彼此間的相關程度。分析結果顯示:上顎中門齒近心唇側切端位於門齒乳突中點前方約 7.30 +/- 0.64 mm 處,男女間無顯著差異 (p > 0.05)。上顎犬齒咬頭尖端連線位於門齒乳突中點後方約 0.27 +/- 1.30 mm,男女間無顯著差異 (p > 0.05)。相關性分析方面,門齒乳突中點至上顎中門齒近心唇側切端與門齒乳突中點至上顎犬齒咬頭尖端連線之水平距離無顯著相關 (r < 0.5)。本研究顯示門齒乳突可作為上顎前牙位置的指標。 |
英文摘要 | The use of the incisive papilla as an important guide for setting maxillary teeth has been applied in prosthetic dentistry. The purpose of this study was to estimate the relationship between maxillary anterior teeth and the incisive papilla of young adults with approximately optimal occlusion in Taiwan. Study casts of 100 young adults (50 males, 50 females; mean age, 22.4 years) were selected in this study. All of the marked points on maxillary casts were measured using a three-dimensional precise measuring device. The relative positions of maxillary teeth landmarks to incisive papilla were measured and analyzed using SAS software (JMP 4.02). Student's t test and Pearson's correlation test were used to test the statistical significance of any differences (p < 0.05).The results showed that the mesiolabial incisal edge of the upper central incisor was 7.30 +/- 0.64 mm anterior to the center of the incisive papilla. There was no significant difference in gender (p > 0.05). The intercanine line was 0.27 +/- 1.30 mm posterior to the center of incisive papilla. There was no significant difference in gender (p > 0.05). The horizontal distances of the mesiolabial incisal edge of the upper central incisor and the intercanine line to the center of the incisive papilla showed only weak correlation (r < 0.5). In addition, the three-dimensional relationship of maxillary anterior teeth to the center of the incisive papilla was measured and analyzed. We suggest using the incisive papilla as a reference landmark for the setting of maxillary anterior teeth. |
