Background:
It has been previously published that the frontal branch of the middle meningeal artery (MMA) is usually embedded in a bony canal (BC). Although the incidence of the BC was over 70%, this structure is currently omitted both in anatomical nomenclature and in most of the literature. We found the same gap pertaining to the grooves for the...

... In order to understand why it does matter, it is necessary to recall the cranial concept and its implications for orthodontics. [1][2][3][4][5][6][7][8][9] The presence of cranial, facial and dental arch asymmetry is a major result of the various cranial strains. By identifying these strains, effective steps can be taken to correct any dental or facial imbalance. ...
Current techniques for palatal expansion are reviewed. Pre-treatment asymmetry of the palate and maxillary arch is shown to be almost universal and is not randomly distributed. The use of a symmetrical expansion appliance does not necessarily result in a symmetrical arch. ALF appliances provide a means of achieving orthopedic, symmetrical expansion of the palate by using very light force. This is demonstrated in seven subjects. It is argued that rapid palatal expansion is an inappropriate, potentially iatrogenic procedure which no longer has a place in the orthodontic armamentarium.
Relevance . The narrowing of the maxilla is one of the most common pathologies in orthodontics. Recent studies show that the narrowing is always asymmetric which is connected to the rotation of the maxilla. To choose the treatment correctly one need a calculation that reveals the asymmetry, which is impossible with using standard indexes.
Purpose – to compare efficiency of indexes of Pont and Korkhause with the Kernott's method in patients with narrowing of the maxilla.
Materials and methods. The study involved 35 children aged from 8 to 12 years old undergoing dental treatment in the University Children's Clinical Hospital of the First Moscow State Medical University with no comorbidities. For every patient a gypsum model was prepared and after that to carry out the biometrical calculation. In this study two indexes were used: Pont's index and Korkhause's; using this standard analysis the narrowing of the maxilla was revealed. After using Pont's Index and Korkhaus analysis all the models were calculated by the method of Kernott with Kernott's dynamic pentagon.
Results. As a result of the analysis of the control diagnostic models a narrowing of the maxilla in 69% of cases (n = 24) was revealed in all cases, the deviation of the size of the dentition was asymmetric. Thus, 65% of the surveyed models showed a narrowing on the right. This narrowing was of a different severity and averaged 15 control models.
Conclusions . This shows that for the biometrics of diagnostic models it is necessary to use methods that allow to estimate the width of the dentition rows on the left and on the right separately. To correct the asymmetric narrowing of the dentition, it is preferable to use non-classical expanding devices that act equally on the left and right sides separetly.
Adult orthopedic and orthodontic treatment requires a more circumspect sensibility in diagnosis, technology selection, reasons for treatment, and patient goals. Many adults present with asymmetries of the dental arches, the cranium, and the entire body. The use of the Advanced Lightwire Functional (ALF) appliance for adult orthopedic treatment will be shown. The appliance construction, application, rational, indications for use, and the results of adding this appliance to an adult treatment regimen will be explored.
This article describes the Inferior Vertical Cranial Strain, one of the seven possible cranial strains that are discussed in this series of articles. Clinicians have to understand cranial strains to better treat their patients. There is a major link between the malocclusion we see and the underlying physiology of the patients. With airway restriction, it is necessary to understand the cranial, postural and facial factors as well as the soft tissue contribution for a more effective overall treatment of the patient.
