[Development of the first Russian CAD/CAM-system--Optik Dent].

Russian dental CAD/CAM-system Optik Dent including intraoral camera for noncontact 3D object (prepared tooth or dental cast) measurement, software for 3D tooth surface reconstruction and digital modeling of restoration, NC machine tool for automated manufacturing of restorations from dental ceramics was presented in this article.

[Microbiological validation of the choice of basic plastic for removable dentures]. / Mikrobiologicheskoe obosnovanie vybora bazisnoi plastmassy s"emnykh zubnykh protezov.

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.

[Clinical and laboratory studies of bacterial adhesion to validate the choice of material for making provisional dentures for patients with periodontal diseases]. / Vybor konsruktsionnogo materiala dlia izgotovleniia vremennykh zubnykh protezov litsam s bolezniami parodonta na osnovanii klinicheskikh i laboratornykh issledovanii bakterial'noi adgezii.

Adhesion of bacteria favoring the development of oral inflammations, including cariesogenic and periodontopathogenic (Actinobacillus actinomycetemcommitans, Streptococcus sanguis, Fusobacterium nucleatum, Staphylococcus warneri) and yeast fungi (Candida albicans), to 13 materials used for making provisional dentures was studied. Adhesion of all the studied bacteria and fungi to Russian material Esterfil Foto was the minimum. Clinical use of this material in patients with chronic generalized periodontitis showed that it was well tolerated and the treatment led to improvement of oral microbiocenosis.

[Disturbance of liver functions and dysbiosis in patients with lipid distress syndrome and its treatment with lactulose preparation "Duphalac" (lactulose)]. / Narushenie funktsii pecheni i disbioz pri lipidnom distress-sindrome i ikh lechenie preparatom "Dufalak" (Laktuloza).

Disturbances of liver's functions and its connection with microflora pathology of large intestine were examined in the patients with lipid dysstress-syndrome. Severe dysbiosis (reduce of light fatty acids level and increase of anaerobe index) was revealed. Efficiency of "Dufalak" (lactulose disaccharide) on liver's functions was estimated.

[Mineralization in the bone of the rabbit mandible after Biositall implantation]. / Mineralizatsiia v kosti nizhnei cheliusti krolika posle vvedeniia implantata iz "Biositalla".

Osteogenic morphological results were assessed at the place of contact of an implant biosital with the lower alveolar jaw-bone in 10 rabbits. Primary mineralization was characterized by the presence of active forming cells and calcified calcospherite structures. Intensive primary mineralization suggests biosital to be a stimulus for ossification (bone formation) promoting favorable interaction tissue implant.
