“…Orofacial anatomy, namely dental anatomy, is recording along individual life by health professionals into the clinical record. The goal of orofacial practice requires the understanding of the two-dimensional (2D) and three-dimensional (3D) morpho-anatomy of the stomatognathic system [1][2][3][4][5]. Normal anatomy allows for the comparative assumption to define the abnormal condition [1,3].…”

The objectives of this study were to identify and correlate orofacial anatomy discrepancies as biometric data and the impact of its rehabilitation as an educational, forensic approach to human identification. An observational and retrospective cohort study was performed on cephalography and photographic exams of a clinical database. The clinical reports were randomly selected according to inclusion and exclusion criteria, reviewed, and interpreted according to the anatomical features. The anatomic features analyzed for human identification compare pre- and post-medical intervention data. The challenging anatomical area was the lower one-third of the face. In an extreme forensic condition, identification should consider the medical history for a positive and accurate conclusion.

“…Many participants expressed seeing bone digitalization on social media (n = 43) and museum websites (n = 45). Although social media offers the opportunity for scientists to engage in virtual communities worldwide, the unselective sharing of imagery of human bodies and human remains on social media can be problematic since, most times, it does not offer context information or donors' consent-we may either assume it exists or not [37]. Also, the specific circumstances behind posting 3D models are unknown, as they are often non-disclosed.…”

Advancements in digital technology have conquered a place in cultural heritage. The widespread use of three-dimensional scanners in bioanthropology have increased the production of 3D digital replicas of human bones that are freely distributed online. However, ethical considerations about such 3D models have not reached Portuguese society, making it impossible to assess their societal impact and people’s perception of how these models are created and used. Therefore, Portuguese residents were asked to take part in an online survey. The ratio of male to female participants was 0.5:1 in 312 contributors. The age ranged between 18 and 69 years. The majority had a higher education degree. Only 43% had seen a 3D model, and 43% considered the 3D replicas the same as real bone. Also, 87% would be willing to allow their skeleton and family members to be digitalized after death, and 64% advocated the controlled dissemination of replicas through registration and login and context description association (84%). Overall, the results suggest agreement in disseminating 3D digital replicas of human bones. On a final note, the limited number of participants may be interpreted as a lack of interest in the topic or, more importantly, a low self-assessment of their opinion on the subject.

“…Before any orthognathic surgical procedure, regardless of whether it is a class II or III malocclusion, it is essential to evaluate the correlation between cephalometric variables and the temporomandibular joint and to define the skeletal pattern [ 29 ]. CBCT obtained 3D representations can be used to describe the intrinsic variability of the mandible in healthy individuals [ 30 ]. In this study, we explored the relationships between the TMJ components, along with the mandibular condyle and the temporal bone, based on the anterior and posterior joint spaces, the medial joint space, and the condyle angle concerning the transverse line using CBCT.…”

This study aimed at evaluating the mandibular condyle position changes before and after bimaxillary orthognathic surgery in class II and III malocclusion patients. CBCT scans from patients who underwent bimaxillary orthognathic surgery were analyzed: Le Fort I osteotomy and bilateral sagittal split osteotomy (BSSO). Both condyles were independently assessed for their largest anterior and posterior joint spaces, smallest medial joint spaces, and condyle angles concerning the transverse line. In the sagittal plane, the minimum size of the anterior and posterior joint spaces was measured. In the coronal plane, the smallest medial joint space was measured. The position of the condyle within the glenoid fossa was determined before and after surgery. A total of 56 TMJs from 28 patients were studied. Following orthognathic surgery, the anterior and posterior space in class II increased. Postoperatively, the anterior joint space in class III decreased. In 42.85% of malocclusion class II patients and 57.14% of malocclusion class III patients, the pre-and post-surgical position of the condyle changed, the condyle was anteriorly positioned (42.85%) in class II patients and centrically positioned (71.4%) in class III patients. Significant changes in the joint space, condylar position, and condyle angle were found in the class II and class III subjects.
