Three-dimensional spiral computed tomographic imaging: a new approach to the diagnosis and treatment planning of impacted teeth

Yuxue Chen et al. Am J Orthod Dentofacial Orthop. 2006 Jul.

Abstract

Introduction: The aim of this investigation was to explore the validity of 3-dimensional (3D) spiral computed tomographic (CT) images to examine impacted teeth before surgical or orthodontic treatment.

Methods: Two patients with impacted teeth were examined with both spiral CT and traditional radiographs.

Results: 3D CT images clearly showed the impacted teeth, including crown, root neck, and root bifurcation; the labial or palatal location; and the eruption orientation and relationship to the dentition.

Conclusion: 3D CT images obtained with 3D surface reconstruction of spiral CT images is accurate and effective for examining impacted teeth before orthodontic treatment.
