“…The spatial resolution of CBCT is about 0.6 mm. In areas where there is no bone on the image, the bone may indeed be missing or its thickness may be <0.6 mm; spatial representation of thin bone areas, such as the anterior alveolar bone, may not be accurate 9,24,25 . The voxel size of CBCT data used in the study was 0.3 mm; high‐quality CBCT data may allow more accurate assessment of alveolar bone morphology.…”

“…DISCUSS IONIt may be difficult to accurately assess the lateral incisor position and alveolar bone using traditional cephalometric images because of structural overlap and the curvature of the radiograph 8. CBCT allows visualization of the three-dimensional structure of the alveolar bone and accurate evaluation of alveolar height and thickness, which makes clinical diagnosis and treatment easier 9. …”

IntroductionPalatal displacement of maxillary anterior teeth is common in clinical practice. Previous studies have reported that the labial bone around palatally‐displaced incisors is thinner than that around normally‐placed teeth. Therefore, it is necessary to elucidate alveolar bone changes after alignment to guide orthodontic treatment. In this study, we investigated the alveolar bone changes around palatally‐displaced maxillary lateral incisors before and after treatment, and the effects of extraction and age using cone‐beam computed tomography.MethodsIn this retrospective study, 55 patients with unilateral palatally‐displaced maxillary lateral incisors were included. Three‐dimensional alveolar bone changes were measured at three levels (25%, 50% and 75% of the root length) using cone‐beam computed tomography. Group comparisons were made between displaced and control teeth, extraction and non‐extraction groups, and adult and minor groups.ResultsAfter orthodontic treatment, labiopalatal and palatal alveolar bone widths decreased at all measured levels. Labial alveolar bone width increased significantly at P25, but decreased at P75. Concavity decreased, while tooth‐axis angle, tooth length, B‐CEJ and P‐CEJ increased. Changes in LB and LP at P75, B‐CEJ and P‐CEJ were statistically significant. After treatment, the tooth‐axis angle on the PD side increased by 9.46°. The change in tooth‐axis angle on the PD side was significantly smaller, and LB and LP decreased more at P75, in the extraction group.ConclusionsCompared to the control teeth, alveolar bone thickness and height for the displaced teeth decreased more significantly after treatment. Tooth extraction and age also influenced alveolar bone changes.

“…Ericson and Kurol found [23] that 8% of impacted maxillary canine could not be accurately located in the lip and palate by periapical X-ray. Kau et al [24] stated that in complex orthodontic cases, such as impacted canines and cleft lip and palate, three-dimensional imaging must be performed, and CBCT is the rst choice. CBCT is of great value in evaluating key parameters such as bone thickness, tooth position and tooth morphology of multiple impacted teeth, which can make it possible to visualize, diagnose and predict the treatment outcome of impacted teeth.…”

Purpose We report a rare case of multiple retained primary teeth combine with impacted permanent teeth in healthy adult female. The diagnosis was confirmed by general oral examination and a cone-beam computed tomography (CBCT). The clinical significance of CBCT in the diagnosis and treatment of impacted teeth was also discussed. Methods Multiple retention of deciduous teeth and impacted permanent teeth were diagnosed by oral general examination combine with CBCT. In conjunction with the literature on impacted teeth, we discussed the diagnosis and the concept of treatment of this rare case. Results A rare case of primary teeth 53, 55, 63, 65, 74, 85 were retained; permanent teeth 13, 15, 17, 23, 25, 27, 34, 35, 45, 47 were impacted; permanent teeth 42 was congenital deletion; permanent teeth 24 and 44 were severely rotated, which were diagnosed by oral general examination combine with CBCT. Conclusion Multiple permanent teeth were impacted is a rare dental anomaly and often found in association with syndromes such as cleidocranial dysplasia or Gardner’s syndrome. However, we report an adult female with multiple impacted teeth who didn’t possess any systemic conditions or syndromes involving both jaws. Based on the oral general examination, auxiliary CBCT examination and literature on impacted teeth, this paper discusses the differential diagnosis and management of this case.
