上颌天然牙列与全口义齿前牙排列位置的测量分析

摘要

Objective :To evaluate the relationship between the incisive papilla and maxillary anterior teeth of dentulous and edentulous jaws ,in order to give some clinical guidance for teeth arrangement of complete denture .Methods :Selec-ting 60 adult maxillary dentulous casts with normal occlusion ,and 57 upper complete denture models of edentulous pa-tients repaired in our stomatological hospital .The relationship between incisive papilla and maxillary anterior teeth were measured ,including the distance between incisor and papilla (IEP) ,intercanine line and papilla (Dip-c ) .All data were input into SPSS14 .0 system and were analyzed with statistic analysis between different groups and sex .Results:In the dentulous group ,the average IEP distance was (8 .96 ± 1 .24)mm and the average Dip-cdistance was (-0 .20 ± 1.12) mm .In the edentulous group ,The average IEP distance was (6 .33 ± 2 .02)mm and the average Dip-c distance was (2.19 ± 1 .31)mm .No difference was found for different sex in each group (P>0 .05) .The distances between the two groups had significant differences (P<0 .05) .Conclusion:The relationship between incisive papilla and maxillary anterior teeth was constant in the dentulous group .But these values are less for artificial teeth than natural dentitions .%目的：调研上颌全口义齿前牙排列位置的现状，以指导临床工作。方法：为60例天然牙列人群及57例上颌总义齿患者制取上颌牙列模型，各组按性别分别测量切牙乳突中点到1｜1唇面距离（IEP）、到3｜3牙尖连线距离（Dip-c ），并将测量结果用SPSS14．0软件统计分析。结果：60例天然牙列测量结果：IEP为（8．96±1．24）mm ，Dip-c为（-0．20±1．12）mm ；57例上颌全口义齿测量结果：IEP为（6．33±2．02）mm ，Dip-c为（2．19±1．31）mm ，两组内所测数据无性别间差异，但两组间存在显著差异。结论：天然牙列中上颌前牙与切牙乳突存在较恒定的位置关系，但全口义齿较天然牙列中切牙距切牙乳突的距离明显减小。
