本研究以五位无牙颌患者为研究对象，采用两种不同的印模方法来复制其上颌骨组织形态。一种手术使用建模塑料来模制间隔托盘的边界，而组织轮廓用常规体多硫化物记录。第二个程序使用组织处理材料来模制选择性间隔托盘的边缘，同时在轻质多硫化物中完成印模。对同一患者重复三次。比较前磨牙和磨牙冠状面的铸型轮廓表明：（1）两种手术的结果没有显著差异;（2）周围组织易于移位，操作量最少;（3）推荐第二种手术，因为对患者方便，对临床医生省时。
Two different impression procedures were used to reproduce the maxillary tissue form of five edentulous patients. One procedure used modeling plastic to mold the borders of spaced trays while the tissue contour was recorded with regular-body polysulfide. The second procedure used tissue treatment material to mold the borders of selectively spaced trays while the impression was completed in light-body polysulfide. Each procedure was repeated three times for the same patient. Comparison of the profiles of the casts at premolar and molar coronal sections showed that (1) there was no significant difference in results between the procedures, (2) peripheral tissues were readily displaceable with the least manipulation, and (3) the second procedure is recommended because of convenience to the patient and time efficiency for the clinician.
