Thirty patients receiving 53 combined crowns with occlusal rest are described. The results are presented in tables. Poor marginal contact was found in about 20% and only 25% of the crowns penetrated into the gingival pouch at a distance over 0.6 mm.

The combined crown used since many years in the Prosthetic Laboratory, Institute of Stomatology, Medical Academy in Gdansk contains an occlusal rest basis of a cast crown (the metal part is of a gold alloy or chromium-nickel steel, with veneer of acrylateor Colorstat) provides, owing to a special preparation of the abutment tooth and laboratory procedure, full stabilization of the crown, protection of parodontium and good maintenance of the veneer which plays a cosmetic role in this type of crown. The combined crowns with occlusal rest are particularly suitable for supporting bridgeworks. They may be applied onto devitalized or live teeth since they require less extensive grinding of teeth.

[Prosthetic treatment by fixed dentures as an aspect of dental caries prophylaxis and periodontal diseases]. / Leczenie protetyczne protezami stalymi w aspekcie profilaktyki próchnicy i chorob przyzebia.

The application of the new, more rational clinical and laboratory management methods of the fixed dentures performance in the Prosthetics Department in Gdansk is the aim of the paper. The methods and materials take dental caries prophylaxis and parodontium protection into consideration and they are based on: grinding limiting and application of partial crowns for installation instead of normal cost crowns; in the partial crowns there were used such composite materials as: Evicrol, Izopast, Izosit and others. Recently ABC preparation (Adhesive-Bridge-Cement) has also been used. The range of the partial crowns described application is various; they are applied not only in the anterior segments but also in the lateral parts of the dental arch. Wearing fixed dentures together with abiding by the hygienic regime is the common element of all modern, accurate and also careful for the dental tissues and noninvasive for the parodontium methods of treatment by fixed dentures.

[Selected cases of prosthetic treatment in patients with lowered height of the occlusion]. / Wybrane przypadki leczenia protetycznego pacjentów z obnizona wysokoscia zwarcia.

In the paper three selected cases that illustrate comprehensive prosthetic treatment in which modern methods and prosthetic materials have been used non-conventional composed bridges with partial crowns on abutment teeth sealed with composites in patients with deep bite are reported. For facing the crowns and bridges such materials as Izosit, porcelain, acryl-derived material--Colorstat which is superior to acrylate considering its physicochemical properties have been used. For the reconstruction of the patients, own teeth Izofil adhesive material has been used for capping the teeth partly or totally establishing a new occlusal situation in anterior and lateral segments.
