Seventy two cases of selection error of upper anterior artificial teeth due to the esthetic factors were investigated out of the 1,507 cases of removable dentures, which were made at the Prosthodontics department of Nihon University school of dentistry at Matsudo for 17 years from November, 1971 to November, 1988. The following were the results of the investigation. 1. Frequency of the selection errors amounted to 4.8% of the total selected cases as broken down in 1.6% by Shade and 4.0% by Mould, the rate of selection errors of the Mould being significantly high. 2. By Mould, selection errors in Ovoid type occupied a significantly high rate. 3. Regarding frequency of Mould after re-selection ST and TO occupied a high rate of 45.9%. 4. Mould of re-selection were almost uniformly small, showing a trend of intumescence becoming emphatically.
在1971年11月至1988年11月的17年间，日本大学松户齿科大学齿槽外科制作的1507例可摘局部义齿中，调查了72例因美学因素导致上前牙人工牙选择错误的病例。以下是调查结果。1. 选择错误的发生率占所选病例总数的4.8%，按色调分类为1.6%，按形态分类为4.0%，形态选择错误率显著较高。2. 按形态分类，卵形的选择错误率显著较高。3. 重新选择后的形态频率中，ST和TO占45.9%的高比例。4. 重新选择的形态几乎都偏小，呈现出明显的肿胀趋势。
