[Evaluation of the dynamics of prosthetic dental care provided to patients with the complete absence of teeth in the Perm district]. / Otsenka dinamiki ob"ema ortopedicheskoi pomoshchi patsientam s polnym otsutstviem zubov v Permskom krae.

BACKGROUND: Currently, one third of the world's population aged 65-74 years has partially or completely missing teeth. In our country, the data of epidemiological studies are scattered. OBJECTIVE: The aim of the study is assessment of the dynamics of the volume of orthopedic care provided to patients with complete absence of teeth in the Perm Region. MATERIAL AND METHODS: The study of the volume of orthopedic care provided to patients with complete absence of teeth was carried out on the basis of a detailed retrospective analysis of their referral to dental clinics in the Perm Region for the period from 2014 to 2020. To assess the long-term dynamics of indicators of the volume of orthopedic care provided to patients with complete absence of teeth, the least squares method was used-gradation of growth rates. RESULTS: This investigation shows the trend of increasing the volume of orthopedic care provided to patients with complete absence of teeth for the period from 2014 to 2020. The average annual growth rate was 5.2%, this situation may be partly due to the accumulation of chronic inflammatory diseases of the oral cavity in the population. Among the patients who applied for dental orthopedic care with complete absence of teeth, women prevailed - 61.8%. The average age of patients with complete absence of teeth was 63.2±1.6 years. CONCLUSION: The trend of increasing the volume of orthopedic care provided to patients with complete absence of teeth in the Perm Region indicates unfavorable changes in the overall dental morbidity over the period 2014-2020 and increased availability of removable dentures with complete loss of teeth. Forecasting the volume of care for patients in this category is important for planning preventive measures.

[Prospects for the use of nanomaterials and high technology in dentistry. Part 1].

The paper presents the possibility of using biologically inert nanomaterials and high technology in prosthetic dentistry. Protective coating of nanostructured titanium VT1-00 magnetic elements of the locking system of removable dentures provides durability and biological inertness and high quality aesthetic design. In assessing the microstructure of titanium protective coating of ferromagnetic elements and samarium-cobalt magnets found that the nanocrystalline coating is formed, resistant to external influences, can significantly improve strength, technical and biological characteristics of samarium-cobalt magnets and ferromagnetic alloys. Fifteen patients were manufactured dentures with magnetic locks. The analysis of performance evaluation prosthetic treatment of patients with the use of the proposed prosthetic shows that the majority of patients (86.6%) obtained a good result. Patients registered restoration of aesthetic standards and the basic functions of dentition.

[Mandibular bone tissue regeneration after the introduction of the implantation system performed on the basis of carbon composite material].

The purpose of this study was to investigate the processes of regeneration of bone tissue after the introduction of new implant systems. In the experiment, performed on 10 male pigs of Landras breed aged 50-55 days and weighing 17-18.5 kg, the time course of histological changes was studied in the area of mandibular regeneration after the formation of tissue defect and the introduction of the implant of a proposed construction. Morphological analysis of the experimental results 90, 180 and 270 days after the operation demonstrated the process of reparative regeneration of damaged bone along implant-bone block boundaries. Bone repair proceeded through the stage of formation of the woven bone with its progressive substitution by the lamellar bone, with the maintenance of the shape, size and symmetry of the damaged organ.

[The effectiveness of the application of mineral water from the Klyuchi health resort in the programs of combined spa-based rehabilitation of the patients presenting with acquired jaw defects].

The results of the present study give evidence of the well-apparent sanation effect of balneotherapy with the use of therapeutic mineral water (MW) extracted at the Klyuchi health resort. Irrigation of the oral cavity with this mineral water was shown to reduce the number of the strains of opportunistic microorganisms and their virulence potential. It is concluded that the proposed method may be recommended for the treatment and prevention of dysbiosis in the oral cavity of the patients presenting with acquired jaw defects.

[Complex treatment approach in patients with lower jaw defects].

The aim of the study was to evaluate the clinical efficiency of modern materials in complex treatment of patients with lower jaw defects. The study demonstrates the advantages of biologically inert materials (carbon composite material "Uglekon-M" and titanium alloys) for lower jaw defect restoration.
