ABSTRACT
Unifas cement was used for fixation of cermet dentures in 104 patients. Clinical follow-up of 3 months to 3 years duration demonstrated sufficiently high adhesive characteristics, resistance to oral fluid and mechanic loading effects of this cement, which is recommended for wide clinical practice.

Holographic interferometry was used to study strained deformed status of bridge dentures. The technique of measurements with a small holographic system is described. Dentures made of Cr-Ni steel with a principally new method of crown to intermediate part adhesion were under study, as were other bridge denture designs. The findings evidence that holographic interferometry may be used as a sparing method for checking up the quality of casting and adhesion of abutment crowns and an intermediate part of fixed dentures, as well as the strength of adhesion of the facing material (porcelain, plastic) to the metal base of the denture.

The authors describe the usage of thermovisual investigation for diagnostic and treatment control purposes in patients with the temporomandibular joint pathology. In chronic arthritis exacerbations, traumatic arthritis and arthroses the joint thermographic images are different. Thermometry was performed at distinct points of parotidmusticulatory, submandibular and cervical regions. Normal and pathological thermal gradients were found between symmetrical facial sites.
