Abstract

Brušenje zuba u fiksnoj protetici ireverzibilan je postupak, stoga mu je potrebno pristupiti planski, poštujući pritom biološka, mehanička i estetska načela brušenja. Gradivni materijal bitan je čimbenik o kojem ovisi vrsta preparacije uporišnog zuba kao i opseg brušenja. Oblikovanje cervikalnog ruba preparacije iziskuje posebnu pažnju. Obavezna je preparacija sa stepenicom – zaobljenom ili pravokutnom ovisno o gradivnom materijalu. Najčešće se koristi zaobljena stepenica, dok je pravokutna rjeđe indicirana. Opseg brušenja potrebno je prilagoditi gradivnom materijalu. Za neke materijale zub je potrebno izbrusiti više, a za neke manje. Kod potpune kovinske krunice potrebno je najmanje brušenje, nešto veće kod krunica obloženih estetskim materijalima, a najveće kod potpuno keramičkih krunica.

Abstract (english)

Tooth preparation in fixed prosthodontics is an irreversible process therefore it is necessary to make a plan beforehand, while respecting biological, mechanical and aesthetic principles of grinding. Constructive material is an important factor on which the preparation finish line of abutment tooth and the diameter of grinding depend on. Creating cervical preparation requires special attention. Depending on the constructive material, chamfer or shoulder finish line is required. The most commonly used is the chamfer one whilst the shoulder is rarely indicated. The diameter of grinding should be adjusted to the constructive material that is being used. Different materials require different amounts of grinding. The least amount of grinding is used for a complete cast crown, more grinding is required with crowns which are veneered with aesthetic materials and the most amount of grinding is used with all ceramic crowns.
