[The cost of orthodontic treatment in children during the mixed bite period].

In order to analyze the complexity and cost of methods of modern orthodontic treatment for children in the mixed bite period as well as to determine the necessary costs for eliminating dentoalveolar anomalies in primary school children taking into account the prevalence of anomalies we studied the duration and frequency of orthodontist visits during treatment using the 2x4 technique, a removable plate with artificial teeth, a ring with a spacer, a plate with a front bite pad, a plate with a shutter for the tongue, and Twin-block appliance, Dilar mask in combination with an expansion apparatus, plates with a screw, appliance with a hyrax expansion screw. Based on the complexity the salary of the orthodontist and other personnel, the costs of maintaining the doctor’s workplace and the dental technician are calculated. The cost of consumables at the clinical and dental stages was determined considering the purchase prices and the cost of a specific manipulation by weighing or measuring.

Study of the Biocompatibility of Titanium-Niobium Implants by the Parameters of Their Osseointegration under Experimental Conditions.

Superelastic titanium alloys (titanium-niobium-zirconium and titanium-niobium-tantalum) are considered to be the more advantageous choice for dental implants than titanium alloys due to their physico-mechanical properties close to those of the bone tissue. Morphological studies of the biocompatibility of these alloys in comparison with titanium were carried out in vivo. Scanning electron microscopy and microprobe elemental analysis of the tissue along the interface between the bone and titanium/superelastic titanium alloys showed similar morphology and elemental composition both on days 30 (poorly mineralized connective tissue was detected in sites of contact with titanium alloy samples) and 90 after surgery (the surface of the titanium alloy samples was covered with mineralized tissue similar by its composition to the surrounding bone).

[The Analysis of Advantages of Network Structures in Stomatology].

The article analyzes and highlights particular advantages of network structures in health care as exemplified by the network of stomatological clinics «PresiDent». Various approaches to establishment of principles of organization of network structures are proposed.

Experimental Validation of the Efficiency of Gamalant-paste-FORTE Plus, a Russian Osteoinductive Material, in Oral Surgery.

For evaluation of the efficiency of bone substitute, nanostructurized Gamalant-paste-FORTEPlus was placed into a mandibular defect in rats. Bone tissue reparation was evaluated after 30 days by histological methods under a microscope. Use of bone substitute in experimental mandibular defect ensured more complete and rapid restructuring of the bone tissue in comparison with the control (natural healing).

[Experimental base for internal connection dental implants for two-step implantation].

The article contains selected results of comprehensive studies on osseointegration of small diameter internal connection dental implants made of nanostructured titanium. Fatigue tests were carried out by means of new osseointegrated metal etching method.
