AIM: This article describes an experimental protocol designed to optimize surgical orthodontic diagnosis and treatment plan.
MATERIALS AND METHODS: In this study, 15 patients undergoing orthodontic-surgical treatment have been analyzed.The superimposition between models and respective presurgical setup for each group was performed. A best-fit algorithm was used to find the position of the arches in space for which the sum of the discrepancies was the shortest.A punctual variation colorimetric map indicating percentages of areas subjected to different discrepancies was used to evaluate the degree of congruence between the 2 models.Furthermore, for each arch the software provided metric values of maximum positive deviation, maximum negative deviation, mean deviation, and standard deviation that characterize the points compared in the superimposition.
RESULTS: For all the considered patients, the orthodontic preparation for surgery was obtained according to the splint guides and the orthodontic planning.
CONCLUSION: The protocol described here allows high-precision planning of orthodontic-surgical therapy optimization of each treatment phase, with consequent advantages in clinical practice.
