[INDEX OF THE EVALUATION OF MALOCCLUSION EXTENT IN PATIENTS WITH SAGITTAL MALOCCLUSION FORMS].

An integrated approach to diagnosis and preparation of a treatment plan gives us the opportunity to carry out a fully correct treatment. Working with skeletal forms of occlusion anomalies, it is necessary to take into account the severity of maxillofacial changes in order to choose a treatment algorithm. For this purpose, an index has been developed to assess the severity of dental anomalies. To create the index, 120 patients with varying degrees of severity of mesial and distal occlusion were examined. The analysis of dental casts, telerentgenograms of the head in lateral projection and photometric examination were carried out. After analyzing the data, an index was created that reliably proves the severity of maxillofacial anomalies, which is the justification for choosing a method of treatment for patients. The proposed technique is a convenient express method for the diagnosis and planning of treatment of dental anomalies.

SURGICALLY ASSISTED RAPID MAXILLARY EXPANSION: RETROSPECTIVE ANALYSIS OF COMPLICATIONS 2012-2017.

Surgically assisted rapid maxillary expansion (SARME) is a common technique developed to treat skeletally mature patients with transverse maxillary deficiency. Although SARME is supposed to be a relatively safe procedure, it is not completely free of complications. The purpose of this study was to reveal the most typical postoperative SARME complications. Retrospective evaluation of the clinical cases of 665 patients (247 males and 418 females, mean age 25,3 years) with the diagnosis of maxillary transverse deficiency, who underwent SARME in period between 2012 and 2017 at the Clinical Center of Maxillofacial, Plastic Surgery and Dentistry, Moscow. According to the results of the research, the most typical complications of SARME are paresthesia of the infraorbital nerve branches and nasopalatine nerve (198/665), distraction device dislocation (61/665), inflammation in the distraction device area (57/665), insufficient expansion of the maxilla (42/665), asymmetric expansion (27/665). The number of complications revealed indicates that SARME is an operation associated with the risks of postoperative complications. Careful treatment planning, following the operation protocol and performing the minimally invasive access can help to avoid the majority of complications.
