Abstract

STATEMENT OF PROBLEM: Research on the quantification of 3-dimensional tooth movements in patients undergoing treatment using the Dahl principle is lacking. PURPOSE: The purpose of this observational clinical study was to measure the magnitude, direction, duration, and rate of tooth movement occurring in patients to reestablish tooth contact and create restorative space. MATERIAL AND METHODS: A total of 104 paired preoperative and postoperative physical and virtual casts from 26 patients were obtained. Commencement and completion dates were recorded to calculate movement duration to reestablish occlusion. Dental casts were digitized, and the 3-dimensional digital casts obtained were superimpo..
