Uncertainty exists about the forces applied by dentists during dental crown cementation. A measuring system was developed based around a commercially available miniature (3.8 mm high and 12.7 mm diameter) load cell. The load cell was mounted in a finger stall and the applied force measured. Experimental results suggest that dentists typically apply a force to metal crowns of about 60 N for a few seconds, followed by the application of a steady force of about 20 to 30 N. Lower forces are applied to porcelain crowns.
在牙冠粘结过程中，牙医施加的力量存在不确定性。基于一种市售的微型（高3.8毫米、直径12.7毫米）称重传感器开发了一种测量系统。该称重传感器安装在指套中以测量施加的力。实验结果表明，牙医通常会在几秒内向金属牙冠施加约60牛的力，随后施加约20至30牛的稳定力。对瓷牙冠施加的力较小。
