“…This diagnostic tool facilitates data storage and retrieval and could enhance the treatment planning through sharing the electronic data more easily among professionals. 17 Bukhari et al 18 concluded that the virtual models (3shape Ortho system) could be considered an accurate alternative to conventional plaster models in performing space analysis irrespective of crowding severity.…”

The orthodontists grant a considerable importance to dental arch dimensions to attain more stability of the dentition and better esthetics. The aim of this study was to measure tooth size disharmony and dental arch dimensions in both divisions of class II malocclusion and compare them to Normal occlusion as a control group using three dimensional digital models obtained from 3Shape E1 laser scanner (3Shape, Copenhagen, Denmark). This work was performed on 120 dental casts randomly selected from the records of patients (age range 16-22 years) attending the Department of Orthodontics, Faculty of Dentistry, Mansoura University. Various parameters were measured including anterior and overall Bolton ratios, maxillary and mandibular intercanine, interfirst premolar and intermolar widths, maxillary and mandibular arch depth, palatal depth, depth of curve of Spee, overjet and overbite. Mean and standard deviation were calculated. Oneway ANOVA was used to detect possible differences between groups. The findings indicate that Class II division 1 malocclusion showed significantly greater maxillary arch depth, palatal depth, mandibular intercanine, interpremolar and intermolar widths and larger overjet amount in comparison with Class II division 2, while revealed significantly higher values of maxillary arch depth, mandibular intermolar width, curve of Spee, overjet and overbite than Normal Class I. On the other hand Class II division 2 malocclusion had significantly greater overall Bolton ratio, maxillary intermolar width, curve of spee depth and overbite than Class II division 1, while it showed deeper curve of Spee and larger amount of overjet and overbite compared to Normal Class I. The results of the current study can help the clinicians in treatment planning and provide guidance for proper selection of arch wires to obtain post-treatment stability.

Aim: To evaluate the accuracy and the validity of orthodontic diagnostic measurements, as well as virtual tooth transformations using a generic open access 3D software compared to OrthoAnalyzer (3Shape) software; which was previously tested and proven for accuracy. Methods: 40 maxillary and mandibular single arch study models were duplicated and scanned using 3Shape laser scanner. The files were imported into the generic and OrthoAnalyzer software programs; where linear measurements were taken twice to investigate the accuracy of the program. To test the accuracy of the program format, they were printed, rescanned and imported into OrthAnalyzer. Finally, to investigate the accuracy of editing capabilities, linear and angular transformation procedures were performed, superimposed and printed to be rescanned and imported to OrthoAnalyzer for comparison. Results: There was no statistically significant difference between the two groups using the two software programs regarding the accuracy of the linear measurements (p>0.05). There was no statistically significant difference between the different formats among all the measurements, (p>0.05). The editing capabilities also showed no statistically significant difference (p>0.05). Conclusion: The generic 3D software (Meshmixer) was valid and accurate in cast measurements and linear and angular editing procedures. It can be used for orthodontic diagnosis and treatment planning without added costs.

“…The initial stage of digitization and the introduction of computational methods in stomatology include the replacement of physical plaster casts models by digital models [16,17] that are recorded by digital cameras, as presented in Figure 1. This approach overcomes several of the limitations of traditional plaster models; for example, they can be easily damaged, require time for model fabrication, and require space to be set aside for their storage [18].…”

Augmented reality has a wide range of applications in many areas that can extend the study of real objects into the digital world, including stomatology. Real dental objects that were previously examined using their plaster casts are often replaced by their digital models or three-dimensional (3D) prints in the cyber-physical world. This paper reviews a selection of digital methods that have been applied in dentistry, including the use of intra-oral scanning technology for data acquisition and evaluation of fundamental features of dental arches. The methodology includes the use of digital filters and morphological operations for spatial objects analysis, their registration, and evaluation of changes during the treatment of specific disorders. The results include 3D models of selected dental arch objects, which allow a comparison of their shape and position during repeated observations. The proposed methods present digital alternatives to the use of plaster casts for semiautomatic evaluation of dental arch measures. This paper describes some of the advantages of 3D digital technology replacing real world elements and plaster cast dental models in many areas of classical stomatology.
