目的：本研究的目的是调查鹤见大学口腔医院钛义齿的生产情况，并了解我校钛义齿的实际使用情况。方法：对1995年4月至2006年3月11年间鹤见大学口腔医院生产的金属基托义齿进行调查，了解义齿所用金属种类、义齿种类、牙体状况及义齿数量。结果：研究期间共制作金属基托义齿1871枚。其中钴铬合金义齿1290枚（68.9%），钛基义齿350枚（18.7%），加铂金合金义齿231枚（12.3%）。钛义齿组中，全口义齿132例（37.7%），全口覆盖义齿55例（15.7%），可摘局部义齿163例（46.6%）。252口义齿钛基托采用JIS 3型纯钛，占72.0%。平均义齿数为10.9颗，是三种金属基托中最多的，差异有统计学意义（P < 0.01）。结论：我院每年平均移植钛基义齿32枚，与其他金属基托义齿相比，钛基义齿适用于几乎无牙弓的修复。(C) 2008年日本口腔修复学会由爱思唯尔爱尔兰出版。版权所有。
Purpose: The purpose of this study was to survey the production of titanium dentures in Tsurumi University Dental Hospital and to study the actual use of titanium dentures in our university.Methods: The survey was based on the metal base dentures produced at Tsurumi University Dental Hospital during an 11-year period between April 1995 and March 2006, with relation to the types of metals used in the dentures, types of dentures, dental condition, and the number of artificial teeth.Results: 1871 metal base dentures were produced in the study period. The dentures consisted of 1290 cobalt-chromium alloy dentures (68.9%), 350 titanium dentures (18.7%) and 231 platinum-added gold alloy dentures (12.3%). Within the titanium denture groups, 132 were complete dentures (37.7%), 55 were complete overdentures (15.7%) and 163 were removable partial dentures (46.6%). JIS type 3 pure titanium was used in the titanium base of 252 dentures (72.0%). The average number of artificial teeth was 10.9, which was the highest among the three types of metal bases, exhibiting significant differences (P < 0.01).Conclusion: Approximately 32 titanium dentures per year on average were delivered at our university and they were applied to almost edentulous arch compared with the other metal base dentures.
