A statistical survey based on laboratory records was performed on the number of indirect restorations fabricated at the dental hospital of Tokyo Medical and Dental University from April 1 to September 30, 1997. A comparison was also carried out with a previous survey, which had been carried out in 1986, in order to detect any change and possible alterations in the near future. Based on the results of this statistical survey, the conclusions were as follows: 1. A total of 9,126 indirect restorations were fabricated during the six month period in 1997; among them, 8,007 (87.7%) restorations were covered by health insurance and 1,119 (12.3%) restorations were not. 2. The most common restoration was the cast post and core (28.6%), followed by full crowns (18.5%) and removable partial dentures (15.6%). On the other hand, the least number were post crowns (0.03%) and resin jacket crowns (0.2%). 3. When making a comparison with the data in 1986, an increase in the number of removable partial dentures and a decrease in the number of inlays were the most distinctive features. 4. For anterior teeth, resin-veneered crowns were most common, especially for lower teeth. The percentage of restorations, which were not covered by health insurance, decreased from 45.0% (in 1986) to 12.3% (in 1997).
基于实验室记录，对东京医科齿科大学牙科医院在1997年4月1日至9月30日期间制作的间接修复体数量进行了统计调查。还与1986年进行的先前调查进行了比较，以检测近期的任何变化和可能的改变。根据这项统计调查的结果，得出以下结论：1. 1997年的六个月期间共制作了9126个间接修复体；其中，8007个（87.7%）修复体由健康保险覆盖，1119个（12.3%）修复体未被覆盖。2. 最常见的修复体是铸造桩核（28.6%），其次是全冠（18.5%）和可摘局部义齿（15.6%）。另一方面，桩冠（0.03%）和树脂贴面冠（0.2%）的数量最少。3. 与1986年的数据相比，可摘局部义齿数量增加和嵌体数量减少是最显著的特征。4. 对于前牙，树脂贴面冠最常见，尤其是下前牙。未被健康保险覆盖的修复体百分比从1986年的45.0%降至1997年的12.3%。
