3D Evaluation of Impacted Teeth in Maxillomandibular Region Using CBCT

Abstract

The aim of the study was to evaluate the degree and complexity of impacted teeth using 3-dimensional analysis on CBCT. Objectives were to evaluate the position and angulation of impacted teeth in 3 dimensions and any pathology with respect to impacted tooth. The study was conducted on 31 patients who presented with impacted teeth except 3^rd molars. All the conventional records along with CBCT were taken and evaluated Out of 70 teeth evaluated; in maxilla, there were 8 incisors, 34 canines and 1 premolar and in mandible, 14 canines, 3 incisors and 10 premolars. Along the x- axis, 33   canines, 4  incisors and 1 premolar were impacted mesiodistally impacted.In mandible, 8 impacted canines and premolars were mesiodistal and 02 incisors were distomesial. Along the Y- axis, in maxilla, position of impaction was 14 canines at cervical 1/3^rd of adjacent tooth root, 03 incisors at middle 1/3^rd, 03 were at apical 1/3^rd. In mandible, 07 impacted canines were at middle 1/3^rd, 02 incisors at cervical 1/3^rd and 06 premolars at middle 1/3^rd of adjacent tooth root. Along the z axis, in maxilla, 22.9% were buccal, 27.1% palatal and 11.4% midalveolus. In mandible, 2.9% were buccal, 11.4% lingual and 24.3% midalveolus. Prevalence of impacted canine was found to be highest all impactions. Along the x-axis, mesiodistal position was the most common. Along the y-axis, most of the impacted teeth were at middle 1/3^rd of adjacent tooth root. along the z- axis, most common position was the midalveolus.
