“…In more pronounced cases of unilateral malocclusions, adjustment, e.g., by orthodontic treatment, is recommended as they might not only be the reason for facial asymmetries, but also for temporomandibular disorders [78,79]. Recent studies indicate correlations between occlusion and adjacent structures including cervical spine, although the consequences of malocclusion and the success of treatment remain unanswered [80,81]. External and internal forces, e.g., by irregular tongue movements, can cause asymmetries of the dental arches [82].…”

Animal bodies in general and faces in particular show mirror symmetry with respect to the median-sagittal plane, with exceptions rarely occurring. Bilateral symmetry to the median sagittal plane of the body also evolved very early. From an evolutionary point of view, it should therefore have fundamental advantages, e.g., more effective locomotion and chewing abilities. On the other hand, the recognition of bilaterally symmetric patterns is an important module in our visual perception. In particular, the recognition of faces with different spatial orientations and their identification is strongly related to the recognition of bilateral symmetry. Maxillofacial surgery and Dentistry affect effective masticatory function and perceived symmetry of the lower third of the face. Both disciplines have the ability to eliminate or mitigate asymmetries with respect to form and function. In our review, we will demonstrate symmetric structures from single teeth to the whole face. We will further describe different approaches to quantify cranial, facial and dental asymmetries by using either landmarks or 3D surface models. Severe facial asymmetries are usually caused by malformations such as hemifacial hyperplasia, injury or other diseases such as Noma or head and neck cancer. This could be an important sociobiological reason for a correlation between asymmetry and perceived disfigurement. The aim of our review is to show how facial symmetry and attractiveness are related and in what way dental and facial structures and the symmetry of their shape and color influence aesthetic perception. We will further demonstrate how modern technology can be used to improve symmetry in facial prostheses and maxillofacial surgery.

“…A patient may not be aware of this change because the central visual cortex and visual connectomes “re-count” the information such as the head would be in a perfectly horizontal position (for review see Wei, 2018 [ 47 ]). This vertebro-cranio-mandibular relation has been repeatedly verified both in experimental animals [ 48 , 49 ] and human patients [ 50 , 51 , 52 , 53 , 54 ]. Elegant experimental study has been provided by D’Attilio et al [ 48 ], who investigated the impact of occlusal interference on the spine of rats creating composite interferences on the right molar of each rat in the experimental group, observing that all such rats developed scoliotic curvature.…”

“…Moreover, in experimental animals with unilateral occlusal interference, condylar bone resorption of the contralateral side has been observed 1 week later [ 49 ]. This finding has been directly and indirectly verified in human patients [ 50 , 51 , 55 , 56 , 57 , 58 , 59 , 60 ] and the amount of scientific evidence of this phenomenon is rapidly increasing. Of note, when such conditions occur, a change in the occlusal (axilla-mandibular) relationship often leads to misalignment of teeth (malocclusion).…”

(1) Background and Objectives: The aim of this narrative review was to analyze the neuroanatomical and neurophysiological basis of cervicogenic pain in cervico-cranial pain syndromes, focusing particularly on cervico-orofacial syndromes as a background for the proper diagnosis and non-surgical treatment. Relevant literature on the topic from past 120 years has been surveyed. (2) Material and Methods: We surveyed all original papers, reviews, or short communications published in the English, Spanish, Czech or Slovak languages from 1900 to 2020 in major journals. (3) Results: The cervicogenic headache originates from the spinal trigeminal nucleus where axons from the C1–C3 cervical spinal nerves and three branches of the trigeminal nerve converge (trigeminocervical convergence) at the interneurons that mediate cranio-cervical nociceptive interactions. The role of the temporomandibular joint in the broad clinical picture is also important. Despite abundant available experimental and clinical data, cervicogenic orofacial pain may be challenging to diagnose and treat. Crucial non-surgical therapeutic approach is the orthopedic manual therapy focused on correction of body posture, proper alignment of cervical vertebra and restoration of normal function of temporomandibular joint and occlusion. In addition, two novel concepts for the functional synthesis of cervico-cranial interactions are the tricentric concept of mouth sensorimotor control and the concept of a cervicogenic origin of bruxism. (4) Conclusions: Understanding the basis of neuroanatomical and neurophysiological neuromuscular relations enables an effective therapeutic approach based principally on orthopedic manual and dental occlusal treatment.

“…Cardinal et al [1] recently published a very nice paper showing a positive correlation between transverse occlusal changes and positional deviations of the cervical vertebrae. It is a very nice, systematic and well-written study, which will undoubtedly have significant impact on our understanding of the relations of posture and malocclusion.…”
