[Technologies for early diagnosis of oral mucosal diseases].

Objective: Expert evaluation of minimally invasive techniques in the diagnostic algorithm of pathological processes of the oral mucosa.

Material And Methods: Fluorescence stomatoscopy of the oral mucosa of 1520 patients aged 18-65 years with analysis of color code of optical images was carried out. The nature of the disease was established by liquid cytology.

[Comparative analysis of different types of implant-abutment interface on the basis of three-dimensional finite element analysis data].

The purpose of the study was to perform a comparative static and dynamic finite element analysis of various taper and cylindrical implant-abutment connections in three-dimensional (3D) models including: abutment, fixing screw, implant, cortical bone, cancellous bone. 3D implant model was IRIS LIKO-M system (Russia) 4 mm diameter and 10 mm length. All the models (M1-M6) were built in the same way.

[Mathematical rationale and results of clinical use of IRIS short implants].

The aim of the study was to provide a mathematical justification of the possibility of using 6.5 mm IRIS implants and to evaluate the results of orthopedic treatment in patients with partial loss of teeth. For the calculations was constructed of a composite three-dimensional computer models: the abutment screw-implant-bone.

[Development and preclinical studies of insulating membranes based on poly-3-hydroxybutyrate-co-3-hydroxyvalerate for guided bone regeneration].

Bone tissue damages are one of the dominant causes of temporary disability and developmental disability. Currently, there are some methods of guided bone regeneration employing different osteoplastic materials and insulation membranes used in surgery. In this study, we have developed a method of preparation of porous membranes from the biopolymer poly-3-hydroxybutyrate-co-3-hydroxyvalerate (PHBV), produced by a strain of Azotobacter chroococcum 7B.
