Clinical Study on the Diagnosis and Treatment Design of Adolescent Impacted Teeth with CBCT.

Abstract

Abstract: Objective: To provide accurate guidline for clinical diagnosis and treatment design by analyzing 54 maxillary impacted teeth with CBCT three-dimensional technique. Methods: 54 maxillary impacted teeth were three-dimensional reconstructed by the use of CBCT technique. Their direction, position, root conditions and relationship with adjacent teeth were evaluated by CS 3D Imaging analysis software. Results: Maxillary impacted teeth were mostly vertical impacted and crowns were approximately near 1/2 or apex of adjacent teeth root in proportion of 66.7%. The position of the root apex varied in 10 millimeters ranges. The frequency of osseous adhesion was 1.9%. Of 54 maxillary impacted teeth, 45 were erupted by orthodontic traction and 9 were extracted. Conclusion: CBCT can locate impacted teeth precisely and provide an important basis for clinical orthodontic treatment.
