Method of Diagnosis and Treatment of Impacted Teeth on the Upper Jaw

Aim: The aim is to increase the effectiveness of diagnosis and comprehensive treatment of patients with impacted incisors and canines on the maxilla.

Objectives: To develop and propose a new technique for determining the topography of impacted teeth (incisors and canines) on the maxilla, using the highly informative data of cone-beam computed tomography; to apply a new method of diagnosis in the planning of comprehensive orthodontic treatment of patients with impacted teeth; to introduce this method into the clinical practice of orthodontist.

Materials and methods: To obtain a three-dimensional image, the X-ray device “Planmeca Pro Max 3D Mid” with «Planmeca Romexis»-the software for saving, viewing and changing images was used. To build and conduct measurements on the image the program “Dolphin Imaging” (3D Surgery and Ceph Tracing) (USA) was used. A computed tomogram of patient was used to determine the levels of location of impacted teeth and angles of their longitudinal axes inclination in three mutually perpendicular planes according to the proposed technique.

Results and summary: A technique of determining the spatial location of the frontal impacted teeth on the maxilla was developed and introduced into practice of the orthodontist, using data from cone-beam computed tomography. The proposed method allows to determine the level of location and degree of its inclination, that is very important for planning comprehensive orthodontic and surgical treatment of patients with impacted teeth.
