Effect on dimensional accuracy when reattaching fractured lone standing teeth of a cast.
1. Ninety-five percent of the variation in position of reattached lone standing incisor and premolar stone teeth was within the limits of physiologic tooth movement. 2. No significant differences resulted from the use of Class I or Class II stones, the technical experience of the operator, or the diameter of the neck of the tooth. 3. There were significant differences between Duco cement and Eastman 910 used between the tooth fragments, but none between Duco cement used between the tooth fragments and Eastman 910 used on the fracture line. However, with all three techniques, most of the changes were within the physiologic limits of healthy tooth movement.
