[Immunological aspects of pathogenesis of stomatological constructional materials intolerance].

In blood and the mixed saliva of patients with intolerance of stomatologic constructional materials the maintenance of cytokines, factors of humoral answer were investigated. It was established, that in formation of intolerance the increased sensitivity stomatologic constructional materials which is not connected to allergic reaction of immediate type and is, apparently, pseudoallergic or develops on other type. There is an activation of the local immune answer including local synthesis of proinflammatory cytokines, sIgA and hyperactivation of complement system to formation of C3a component. Toxic and allergic action of stomatologic constructional materials grows in patients having antibodies to Candida albicans in the mixed saliva.

[An experimental study of the tissue compatibility of titanium implants coated with hydroxyapatite and aluminum oxide by plasma spraying].

The reaction of bone tissue to implantation of cylindric titanium implants sprayed with hydroxyapatite and aluminum oxide was studied. The coating was characterized by a high biological histocompatibility. The elements of cellular reactions specific for foreign bodies were absent, this permitting us to refer such coating to bioactive materials. The strength of fixation in the bone was compatible to the strength of osseous tissue adjacent to bone tissue implant. The coating may be used in oral implantology, traumatology, and orthodontics.

[A method for preparing a resin-bonded fixed denture with parapulpar pins].

The authors suggest a method for making an adhesive permanent denture with parapulpar dowels consisting in the use of a whole cast conductor for drilling parapulpar channels in the patient's oral cavity. The conductor is cast simultaneously with the prosthesis of the same metal, hence metal shrinkage in casting is the same, this being a guarantee of the denture accuracy.
