Clinical aspect of modern biological restorations: galvano-forming of permanent prosthetic restorations--case report.

Galvano-forming is modern technique used to make esthetic permanent prosthetic restorations displacing lost-wax method. The replacement of wax by metal produces marginal tightness of 70 microm. The technology satisfies esthetic demands, ensures beneficial and long-tern effects. Galvanic products are characterized by high biocompatibility, excellent marginal tightness (tightness of ca 18 microm), pulp protection, chance to apply traditional neutral zinc-phosphate cement and high esthetic quality.

Removable dentures and relations between their construction, adaptation and functionality role and influence on dysgeusia.

A large foreign body inserted into oral cavity, e.g. complete denture, both lower and upper, might cause a temporary or constant dysarthia and dysgeusia. These might be reduced and even completely eliminated by proper dentures construction. Problems with normal articulation might result from construction faults, e.g. too thick denture base, incorrect denture base modelling, wrong teeth placement, lowering or excessive height occlusion. The hypogeusia has been repeatedly observed as the symptom in the course of the complete denture adaptation stage, as well as might keep further. The main role in the mechanism of occurrence of hypogeusia has the limitation of the lingual flexibility, especially of its tip, throughout the use of the complete denture. It provokes difficulties with the accurate course of its physiological activity as well as makes impossible the balancing with the tongue of the cryaesthesia, heath sensibility and tactile sense, which are blocked on the palate.
