[Orthognathic surgery and contour plasty. Synergism or opposition].

The article presents two cases of sisters with malocclusion: distal deep bite with typical skeletal and soft tissue deformation. In the first case classic three-steps orthognatic treatment plan was realized: orthodontic preparation with subsequent orthognatic bi-maxillar surgery with genioplasty. In second one we made contour-plasty with implants.

[Surgical-associated expansion of the jaws with asymmetric deformations].

One of the most common abnormalities in the development of the jaw is the narrowing of the alveolar process of the maxilla. In childhood, the elimination of such a deformation is quite common. But with age, the only effective option is the inclusion of a surgical procedure in the rehabilitation plan.

[A method of osteoplasty of the mental region of the mandible].

Correction of the lower jaw contours is one of the most popular tasks in aesthetic maxillofacial surgery. There are many reduction operations aimed at changing the shape of the lower jaw. However, augmentation mandible plasty is mainly associated with the use of synthetic implants.

Frontal cephalometric landmarking: humans vs artificial neural networks.

Unlabelled: Frontal cephalometric radiography (frontal ceph) is one of the important diagnostic methods in orthodontics and maxillofacial surgery. It allows one to determine occlusion anomalies in the transverse and vertical planes and to evaluate the symmetry of the facial skeleton relative to the median plane, including analysis of the position of the jawbone.

Aim: The aim of this study was to develop an artificial neural network (ANN) for placing cephalometric points (CPs) on frontal cephs and to compare the accuracy of its performance against humans.
