“…Many studies have concluded that volumetric measurement of teeth using CBCT is a reliable, reproducible, and valid method. [16][17][18] As of today, there has been only one study evaluating root resorption after RME with CBCT in vivo. 5 The volumetric data set comprises isotropic structures, known as voxels, each representing a specific degree of X-ray absorption.…”

“…used for each tooth before expansion, after expansion, and after 6 months of retention. 18 Tooth volume loss and its percentage were measured. The percentage of root volume loss was calculated by subtracting the postexpansion root volume from the preexpansion volume.…”

“…11 After CBCT was introduced, several studies were conducted on tooth segmentation and volumetric measurements. [16][17][18] It is possible to detect and measure root resorption with a lower radiation dose and without the need to extract teeth. Only two studies have evaluated volumetrically with CBCT the amount of root resorption occurring during orthodontic treatment.…”

Objective: To compare volumetric root resorption after rapid maxillary expansion (RME) between tooth-borne and tissue-borne appliances using CBCT. Repair in resorption cavities after 6 months of fixed retention was also compared. Materials and Methods: A sample of 33 subjects were randomly divided into two groups: Hyrax (n 5 16) and Haas (n 5 17). CBCT scans were taken 6 months before expansion, immediately after expansion, and 6 months after fixed retention. Mimics Innovation V 16.0 software was used for segmentation and volumetric measurement of 198 teeth. Bland-Altman plots, independent samples t test, repeated measures analysis of variance, and the Friedman test were used for statistical analysis. Results: Differences in root resorption after RME and repair after retention were not significant between the hyrax and Haas appliances or between male and female. Significant differences were found between preexpansion and postexpansion root volumes in the first premolars and molarseven in unattached second premolars. When the percentage of root volume loss is considered, no significant difference was found between the first premolar, second premolar, and first molar. Volumetric changes after 6 months of retention were not statistically significant.

“…This is the first study that has evaluated volumetric computations of alveolar clefts derived from virtual 3D or 3D printed models using CBCT. Several non-cleft studies have evaluated the dimensional accuracy of CBCT scanning compared to micro-CT imaging finding virtual 3D models derived from CBCT scans are accurate for volumetric calculation of teeth 19 and bovine bone cavities. 20 Our results are in line with these and are comparable to other investigations of the dimensional accuracy of CAD models produced from either CT or CBCT scans.…”

Results: Inter-observer reliability was almost perfect (ICC = 0.987). There were no significant differences between the three methods (p>0.05) although virtual 3D models were the most precise with the smallest standard deviations and confidence intervals.Conclusion: In this preliminary investigation, virtual 3D and 3D printed models were as precise as the validated computer algorithm for calculating alveolar cleft volumes prior to bone grafting but virtual 3D models were the most accurate and subject to further investigation could be a useful adjunct in clinical practice.
