Forty autopolymerizing resin record bases were made; 10 bases were adapted by finger pressure on tray resin material dough, 10 bases by sprinkling orthodontic resin, and 10 of repair material by either of the two previous techniques. Stone casts and acrylic resin bases were sectioned at canine, premolar, and molar coronal planes. Width of the gap between base and cast and the thickness of the base were measured at the buccal sulcus, ridge crest, lateral palatal slope, and palatal midpoint. Measurements were made through the eyepiece of a microhardness tester. Statistical analysis of 760 pairs of measurements revealed that (1) sprinkled bases fit better than finger-adapted dough bases; (2) specifically formulated materials fit better than repair material with either technique; (3) gap widths differed at different areas of the same base; and (4) gap width was not related to base thickness at any point.
制作了40个自凝树脂记录基托；10个基托通过手指按压托盘树脂材料面团进行适配，10个基托通过撒布正畸树脂制作，另外10个基托采用上述两种技术中的任何一种使用修复材料制作。将石膏模型和丙烯酸树脂基托在尖牙、前磨牙和磨牙的冠部平面进行切片。在颊沟、牙槽嵴顶、腭侧斜面和腭中点处测量基托与模型之间的间隙宽度以及基托的厚度。通过显微硬度测试仪的目镜进行测量。对760组测量数据的统计分析表明：（1）撒布法制作的基托比手指按压面团法适配的基托贴合度更好；（2）专门配制的材料比采用任何一种技术使用的修复材料贴合度更好；（3）同一基托不同区域的间隙宽度不同；（4）在任何点处间隙宽度与基托厚度均无关。
