“…DDMs show an accurate 3D image of the clinical crown and are reliable for measuring tooth size, arch dimensions and irregularity index [31][32][33][34] and some recent works even suggested the prediction of root position from it. 11,23,24 However, when comparing the changes in mesiodistal and buccolingual angulation using the clinical crown (DDM) and the whole tooth (CBCT), the present study showed that the results were significantly different for most of the variables assessed (Table 1). Figure 6 shows a mandibular canine as an example that the changes in mesiodistal and buccolingual angulation with orthodontic treatment can be different for long axis of the tooth (6A and 6D) and long axis of the crown (6B and 6E).…”

“…Recent studies have proposed a prediction of the 3D root position by merging CBCT scans with DDM. 11,23,24 While similar values for mesiodistal and buccolingual angulation were reported when post-treatment CBCTs were compared to the expected root position setup obtained from intraoral scanner models, it was recommended that practitioners use their best clinical judgement when performing this assessment because outliers were found. 11 The clinical crown can estimate the spatial position (buccolingual, mesiodistal and occlusogingival positions) and the axial rotation of the tooth.…”

Objective-To compare the three-dimensional (3D) linear displacements and the mesiodistal and buccolingual angulation changes after orthodontic treatment in digital dental models (DDMs) and 3D models derived from cone-beam computed tomography (CBCT). Settings and Sample Population-Digital dental model and CBCT scans were selected from 24 adults who had undergone orthodontic treatment for mandibular anterior crowding. Material and Methods-3D linear displacements and changes in angular measurements (mesiodistal and buccolingual angulation) were assessed in pre-and posttreatment DDM and CBCT images using the software ITK-snap and 3D SlicerCMF. Intra-and inter-rater agreement of measurements in DDM and CBCT were tested using the intraclass correlation coefficient (ICC).

“…Therefore, the image of the defective dentition of the CBCT is usually replaced with the 3D image of the scanned dental models using either CT or laser scanner. The fusion of the images can be also achieved between the CBCT and the intra oral scans for orthognathic surgery planning, the accuracy of the method was within 0.5 mm [6].…”

Background: Virtual reality is the science of creating a virtual environment for the assessment of various anatomical regions of the body for the diagnosis, planning and surgical training. Augmented reality is the superimposition of a 3D real environment specific to individual patient onto the surgical filed using semi-transparent glasses to augment the virtual scene.. The aim of this study is to provide an over view of the literature on the application of virtual and augmented reality in oral & maxillofacial surgery. Methods: We reviewed the literature and the existing database using Ovid MEDLINE search, Cochran Library and PubMed. All the studies in the English literature in the last 10 years, from 2009 to 2019 were included. Results: We identified 101 articles related the broad application of virtual reality in oral & maxillofacial surgery. These included the following: Eight systematic reviews, 4 expert reviews, 9 case reports, 5 retrospective surveys, 2 historical perspectives, 13 manuscripts on virtual education and training, 5 on haptic technology, 4 on augmented reality, 10 on image fusion, 41 articles on the prediction planning for orthognathic surgery and maxillofacial reconstruction. Dental implantology and orthognathic surgery are the most frequent applications of virtual reality and augmented reality. Virtual planning improved the accuracy of inserting dental implants using either a statistic guidance or dynamic navigation. In orthognathic surgery, prediction planning and intraoperative navigation are the main applications of virtual reality. Virtual reality has been utilised to improve the delivery of education and the quality of training in oral & maxillofacial surgery by creating a virtual environment of the surgical procedure. Haptic feedback provided an additional immersive reality to improve manual dexterity and improve clinical training. Conclusion: Virtual and augmented reality have contributed to the planning of maxillofacial procedures and surgery training. Few articles highlighted the importance of this technology in improving the quality of patients' care. There are limited prospective randomized studies comparing the impact of virtual reality with the standard methods in delivering oral surgery education.

“…At the end of this analysis, only twelve papers were included in the sample for our systematic review. The other 19 studies were excluded for the following reasons: virtual surgical planning for orthognathic surgery was not the main focus of the paper [19],the paper was not an intervention study [17], or it was not original [5,20,21], the surgical procedure did not involve a computer-assisted virtual surgical splint [22][23][24], the accuracy measurements for the surgical procedure were not provided [25][26][27][28][29] and the sample size was less than 10 [16,22,[30][31][32][33].…”

Background The elaboration of a precise pre-surgical plan is essential during surgical treatment of dentofacial deformities. The aim of this study was to evaluate the accuracy of computer-aided simulation compared with the actual surgical outcome, following orthognathic surgery reported in clinical trials. Methods Our search was performed in PubMed, EMBASE, Cochrane Library and SciELO for articles published in the last decade. A total of 392 articles identified were assessed independently and in a blinded manner using eligibility criteria, out of which only twelve articles were selected for inclusion in our research. Data were presented using intra-class correlation coefficient, and linear and angular differences in three planes. Results The comparison of the accuracy analyses of the examined method has shown an average translation (< 2 mm) in the maxilla and also in the mandible (in three planes). The accuracy values for pitch, yaw, and roll (°) were (< 2.75, < 1.7 and < 1.1) for the maxilla, respectively, and (< 2.75, < 1.8, < 1.1) for the mandible. Cone-beam computed tomography (CBCT) with intra-oral scans of the dental casts is the most used imaging protocols for virtual orthognathic planning. Furthermore, calculation of the linear and angular differences between the virtual plan and postoperative outcomes was the most frequented method used for accuracy assessment (10 out of 12 studies) and a difference less than 2 mm/° was considered acceptable and accurate. When comparing this technique with the classical planning, virtual planning appears to be more accurate, especially in terms of frontal symmetry. Conclusion Virtual planning seems to be an accurate and reproducible method for orthognathic treatment planning. However, more clinical trials are needed to clearly determine the accuracy and validation of the virtual planning in orthognathic surgery.
