ABSTRACT
Expericnce of working out of tools of quality management of maxillofacial prosthetics which can be applied in clinical practice of maxillofacial orthopedy is presented. The fragment of the algorithm of maxillofacial prosthetics developed by authors is presented.

327 patients with dentures supported by 318 pulpless teeth reinforced by pin constructions were under observation. Main types of complications after pin use were identified. By math simulation the system "covering construction-artificial stump-root pin-root of the tooth" was studied for teeth 11, 13, 15, 16, 41, 43, 45, 46 in two projections--vestibulo-oral and mesio-distal. Margins of strength properties of teeth armed by special pin constructions (made as individual casting) and artificial stump with standard pins made of different materials were determined. Optimal parameters of height and width of off-root part and intra-root pin sizes in different teeth groups in conformity with their individual anatomic peculiarities were established.

Adhesion of obligate and facultative anaerobic bacteria, favoring the development of oral inflammatory diseases, including the cariesogenic and periodontogenic bacteria and Candida albicans fungi, isolated from patients with periodontitis, to 13 basic materials used in removable denture making, was studied. The adhesion of all bacteria (Streptococcus sanguis, Prevotella melangogenica, Fusobacterium nucleatum, Corynebacterium xerosis) and fungi to hot polymerization basic materials was the maximum. The most perspective basic plastic for clinical use (preserving intact oral microbiocenosis and preventing stomatitis induced by denture wearing) are cold polymerization materials, such as Redont-03, Dentoplast Breden, Leocryl, and UHF polymerization materials Acron GC, AKR-MV, and Etakril-02.

A computer study of 99 types of mathematical models of teeth armed with stump pin insertions widely used in dentistry (group 1--anchor pins and group 2--cast pin insertions suggested by the authors). Tooth models differed by shape, size, and properties of the design material. The shape and parameters of stump pin insertion were proven to be more significant than the properties of design material. The choice of pin design is determined by the clinical situation, topography and anatomy of tooth crown destruction, and maxillodental disease.

The article considers the indications and possibilities of using the device for flowing extracorporeal ultraviolet radiation of blood. The uniformity of the radiation of blood in the proposed device provides an annular gap of the quartz dish with the partition in the shape of a spiral. It makes it possible to expose a larger part of the blood content of an organism simultaneously making use of various perfused methods of its detoxication.
