Abstract:Krčenje polimernih kompozitov med strjevanjem, kljub stalnemu napredku in razvoju, še vedno povzroča težave v dentalni medicini. Skrček je odvisen predvsem od sestave matice, a delno lahko nanj vpliva tudi način polimerizacije; t.j. jakost svetlobnega toka in čas potreben za polimerizacijo kompozitov. Polimerizacijske lučke v dentalni medicini imajo večinoma dvajset sekundni interval polimerizacije. Lučka Flashmax P3 podjetja CMS potrebuje za polimerizacijo kompozitov le tri sekunde in je novost na trgu. Njen vpliv na skrček med polimerizacijo kompozitov še ni bil raziskan. Podjetje Drevenšek & Drevenšek d.o.o. je zastopnik za lučko FlashMax P3 v Sloveniji in je pokazalo zanimanje za takšno raziskavo. Narejena je primerjalna raziskava vpliva lučke FlashMax P3 in lučke Radii Plus podjetja SDI na polimerne kompozite Ice in Glacier podjetja SDI, Gradia podjetja GC in Charisma podjetja Heraeus Kulzer. Vse naštete produkte je priskrbelo podjetje Drevenšek & Drevenšek d.o.o., saj so želeli s podrobno raziskavo izdelkov in storitev, ki jih ponujajo, potrditi njihovo odličnost in neoporečnost. Namen in cilj diplomske naloge je jasno pokazati vpliv vrste polimerizacijskih lučk in časov zamreženja na skrček polimernih kompozitov. Za dokazovanje so uporabljene tri različne metode; in sicer metoda prostega krčenja polimernih kompozitov v jeklenih cevkah, metoda vezanega krčenja polimernih kompozitov v zobeh in metoda izvleka oziroma »pull-out« metoda.
Keywords:Polimerni kompoziti, dentalna medicina, strjevanje, polimerizacija, skrček.

Title:DILATATION OF COMPOSITES USED IN DENTISTRY
Abstract:Shrinkage of polymer composites during polymerisation, despite ongoing progress and development, continues to cause problems in dental medicine. Shrinkage depends mainly on the resin composition, but partialy it is also affected by the method of polymerization, meaning luminous intensity and time required for curing composites. Polymerization lights in dental medicine mostly have twenty-second curing interval. LED light FlashMax P3 from the compay CMS is new on the market and needs only three seconds for curing of the composites. Its impact on the polymerization shrinkage of composites has not yet been studied. The company Drevenšek & Drevenšek d.o.o. is the Slovenian representative for light FlashMax P3 and has shown interest in such a study. We made a comparative study of impact made by Flashmax P3 light from CMS and Radii Plus light from SDI on polymer composites Ice and Glacier – SDI company, Gradia – GC company and Charisma – Heraeus Kulzer company. All of these products had been provided by Drevenšek & Drevenšek d.o.o. because they required a detailed survey of those products to confirm the excellence and integrity of the products and services they offer. The purpose and aim of this thesis is to clearly show the influence of the type of polymerization lights and curing time on the shrinkage of polymer composites. We used three different methods to demonstrate it: the method of free shrinkage of polymer composites in steel tubes, method of bonded shrinkage of polymer composites in teeth and pull-out method.
Keywords:Polymer composites, dental medicine, curing, polymerisation, shrinkage.
