Research on CT diagnostic analysis of three-dimensional magnetic palatal maxillary dentition direction / 中国医学装备

ABSTRACT

Objective:To discuss the changing position in three dimensions of maxillary dentition magnetic arch expansion after.Methods: Thirty patients who were in-patient cases were selected, and received three-dimensional data measured before and after treatment it its spiral CT, observed the three-dimensional position of maxillary dentition before and after treatment, and the angle of landmarks change data paired sign test for comparison.Results: Patients in the vertical position of maxillary dentition before and after treatment, sagittal and horizontal direction are changed. First premolars, first molars occurred cheek overall movement and dumping; the maxillary first premolar region is the largest widening position; three-dimensional position of the maxillary central incisor forward, the next move.Conclusion: Patients before and after the change of maxillary dentition MPE can be clearly presented in accordance with spiral CT, lay the foundation for further research MPE mechanism.
