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. Two different plans follow to two different results. Discussion around all differences of two approaches is the main interest of this overview.

[A method of osteoplasty of the mental region of the mandible]. / Metodika kostnoi plastiki podborodochnogo otdela nizhnei chelyusti.

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. In 2013, A. Triaca published a paper «chin wing technique¼ in detail, which we used as a prototype. In this article, we will present the technique and experience of using osteoplastic three-dimensional mandible plasty, which has a number of special features: the increase in the bigonial width is due to the median vertical osteotomy of the free lower edge of the lower jaw, followed by lateralization of the distal parts of the lower fragments, osteosynthesis is performed using the original trapezoidal titanium mini-plate. Since 2018 30 patients have been operated on with different variants of the anatomy of the lower jaw with requirements for increasing the projection of the chin, increasing the width of the lower third of the face and changing the contour of the mandible. The mandible plasty proposed by us allows us to achieve good aesthetic results and can replace the use of synthetic implants.

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. The medial and parasagittal osteotomy of the maxilla for the purpose of its expansion by a distraction device has a number of important nuances which can significantly affect the result. These include: localization of sagittal osteotomy of the palate and alveolar process; the direction of cutting the walls of the maxillary sinus; type of fixation of the device (dental-borne or bone-borne). The article summarizes the experience of 74 surgical-associated expansions of the jaws with asymmetric deformations performed over 2 years. A retrospective analysis according to cone beam computed tomography is given. of complex treatment with the inclusion of sparing osteotomy of the maxilla in the rehabilitation plan and a differentiated approach to performing surgical manipulation allow to achieve optimal aesthetic and functional results and to correct the asymmetry to the greatest extent.
