The Use of Computed Tomography Data in Diagnosis and Treatment of Patients with Malocclusion Accompanied by the Narrowing of the Maxilla

The Purpose. Create an algorithm of using computed tomographydata in patients with malocclusion, accompanied by the narrowing of the maxilla. Create description CT data protocols. Materials and methods. Were examined 20 patients with malocclusion, accompanied by the narrowing of the maxilla. All CT examinations were performed on Toshiba Aquilion ONE, 320 before treatment and 6 months after rapid maxilla expansion. Description CT protocols of these studies were developed. Results. After rapid maxilla expansion it was found that the maximum expansion of the maxilla was at the level of canines, then at the level of premolars, first molars, second molars. 6 months after distraction the density of bone regenerate in the projection of the median palatal suture was estimated. When the distraction was 1-4 mm regenerate bone density ranged 520-890 HU. When distraction was 4-9 mm density varied 320-614 HU. These indicators gave the opportunity to plan further treatment in this group of patients. Conclusion. Computed tomography is an indispensable study in patients with malocclusion, accompanied by the narrowing of the maxilla, and should be performed in all patients before and after rapid maxilla expansion.
