Abstract

Od 1934. godine na tržištu postoje novi materijali koji su napravljeni na bazi estera akrilne kiseline, a zbog kojih su morali biti razvijeni različiti modeli za polimerizaciju. Akrilati danas imaju široku primjenu u stomatološkoj protetici, a osobito često se koriste za izradu protezne baze. Pod utjecajem topline aktivira se inicijator iz polimera nakon čega započinje proces polimerizacije. Najčešće primjenjivana polimerizacija je ona toplinska koja može biti klasična, ubrzana i injekciona, a prema vremenu trajanja kratkotrajna, srednjetrajna i dugotrajna. Proces polimerizacije ima i svoje nedostatke i komplikacije koje se javljaju uslijed raznih čimbenika. Te komplikacije su: poroznost, granularnost, rezidualni monomer, dimenzionalne promjene, apsorpcija vode i unutarnja napetost.

Abstract (english)

Since 1934 there had been new materials on the market witch are made on base of acrylic acid, therefore had been developed different models of polymerization. Today we can use them for a wide application in dental prosthetics and they are very often used. Heat polymerization is the oldest way of polymerization in dentistry. It is known that under the influence of heat benzyl peroxide becomes active and starts the polymerization process. The heat polymerization can be classic, accelerated and with the use of injections. We can also divide them based on time duration as there are raid cure, medium cure and long cure. The process of polymerization is not flawless as it has its week points such as: porosity, granulation, residual monomer, dimensional changes, and absorption of water and inside tension.
