Abstract
Svrha rada: Svrha ovog in vitro istraživanja bila je istražiti utjecaj različitih obojenih tekućina na stabilnost boje materijala za privremene nadomjeske u fiksnoj protetici proizvedene suvremenim tehnologijama CAD/CAM-a i 3D printanja te usporediti ih s konvencionalnim tehnikama. Materijali i postupci: Proizvedeno je 50 uzoraka (15 x 2 mm) od svakog materijala za privremene nadomjeske (Ceramill Temp, Telio CAD, HUGE DENT, Unifast TRAD, Protemp 4, Protemp II, Telio CS C&B, Freeprint Temp, Nextdent C&B). Uzorci su uronjeni u pet različitih otopina (crno vino, kava, kola, aceto balsamico, destilirana voda) 30 dana. Boja uzoraka mjerena je spektrofotometrom (VITA Easyshade Advance 4.0) na početku i nakon sedam, 14 i 30 dana pohranjivanja u otopinama te su izračunate promjene boje (ΔE). Podaci unutar skupina uspoređeni su statistički koristeći analizu varijance (p < 0,05). Rezultati: Najveće promjene boje na svim materijalima uzrokovalo je crno vino i te su promjene za sve materijale i sva razdoblja bile statistički značajne i vidljive, osim za Ceramill Temp nakon sedam dana. Najveća stabilnost boje zabilježena je za CAD/CAM materijal Ceramill Temp. Statistički najnestabilnijim materijalom pokazao se 3D printani materijal Freeprint Temp. Statistički značajne promjene boje za većinu materijala nisu bile vidljive ljudskom oku. Zaključak: CAD/CAM materijali pokazali su veću stabilnost boje od konvencionalnih i 3D printanih materijala. 3D printani materijali u ovom su istraživanju pokazali su najmanju stabilnost boje. Zbog niske stabilnosti boje, 3D printani materijali ne preporučuju se za izradu dugotrajnih privremenih nadomjestaka.
Abstract (english)
Aim: The aim of the present in vitro study was to investigate the effect of different colored fluids on the colour stability of temporary restorative materials produced by modern CAD/CAM and 3D printing technologies and to compare them to conventional techniques. Materials and methods: A total of 50 samples (15 x 2 mm) of each provisional restorative material (Ceramill Temp, Telio CAD, Huge Dental, Unifast TRAD, Protemp 4, Protemp II, Telio CS C&B, Freeprint temp, Nextdent C&B) were fabricated. The samples were immersed for 30 days in five different solutions (red wine, coffee, Coca-Cola, aceto basamico, distilled water). The colour of all specimens was measured with a spectrophotometer at baseline and 7, 14 and 30 days after immersion, and the colour changes (ΔE) were determined as well. The data within groups were compared statistically using analysis of variance (p < 0.05). Results: The largest colour changes on all materials were caused by red wine and these changes were statistically significant and visible for all materials and all time periods except for Ceramill Temp after 7 days. The highest color stability was observed for CAD/CAM material Ceramill Temp. The most unstable material was the 3D printed material Freeprint Temp. Statistically significant colour changes for most materials were not visible to the naked eye. Conclusion: CAD/ CAM materials showed a better colour stability than convetional and 3D printed materials. Considering the low colour stability, 3D printed provisional materials may not be recommended for long-term provisionals.
