Čujec, Gašper (author), Birsa, Dare (mentor), Rojko, Franc (comentor)

Uvod: Barve in estetika sta poleg funkcionalnosti dentalnih izdelkov največjega pomena. Celoten postopek določanja barve izdelka je zapleten in kompleksen proces. Strokovnjaki z našega področja razvijajo nove instrumente za določanje barv, s katerimi bi lahko dosegali estetsko bolj dovršene izdelke. Namen: Namen diplomskega dela je na praktičnem primeru predstaviti spektrofotometer SpectroShade Micro in sistem »White balance gray reference card« za določanje barve, ter stroki ponazoriti, da se z uporabo novih sistemov dosega boljše rezultate, kot po tradicionalni metodi tj. z uporabo barvnega ključa. Ugotoviti želimo, s katerim sistemom dosežemo boljše končne rezultate izdelkov in kateri od testiranih sistemov je priročnejši ter hitrejši za uporabo. Metode dela: Pri pregledu strokovne literature smo uporabili deskriptivno metodo. Literaturo smo iskali v slovenskem in angleškem jeziku in je obsegala tako strokovne članke v revijah kot tudi strokovne knjige. Na primeru smo z uporabo obeh sistemov določali barvo zob. Na podlagi pridobljenih podatkov smo naredili načrt slojevanja porcelana z željo, da bi bila barva izdelane kovinsko-porcelanske prevleke kar se da podobna barvi, ki nam jo je podal določen sistem. V ugotovitvah smo predstavili, kateri od uporabljenih sistemov je dal boljši končni izdelek. Rezultati: Omenjena sistema za določanje barv sta v primerjavi s tradicionalno metodo določanja barve z barvnimi ključi velik doprinos k bolj estetskim zobnim nadomestkom. Na diplomskem izdelku, kovinsko-porcelanskih prevlekah v vidnem področju na zobeh 11, 12, 21 in 22, smo po načelih analize barve zob naredili prevleke in jih medsebojno primerjali z vidika natančnosti dosežene barve. Razprava in sklep: Tako uporaba spektrofotometra kot tudi »white balance gray reference card« bistveno izboljša estetiko zobnih nadomestkov. Sistema sta enostavna za uporabo, kljub temu pa je čas porabljen za uporabo spektrofotometra krajši kot pri »white balance gray reference card«, slednja je primernejša za izdelavo zahtevnejših prevlek z vidika estetike.

Abstract

Introduction: Colors or aesthetics are in addition to the functionality of dental products the most important factor of stomatology. But the whole process from determining the color to the finished product is complicated and complex. Experts from our field are developing new color-matching instruments to achieve better final results in terms of aesthetics. Purpose: The purpose of the thesis is to present the color matching systems spectrophotometer SpectroShade Micro and »White balance gray reference card« in practice, and demonstrate to colleagues that you can achieve significantly better results by using novelties rather than traditional method i.e. using shade guides. Methods: In the review of literature we used the descriptive method. We searched for literature in Slovene and English language, and it included articles in magazines as well as books. We determined the color of the teeth through practice, using both systems. On the basis of obtained data we determined the colors and made a plan for layering ceramics in order to make the color of the ceramic as similar as possible to the color given to us by a specified system. When we completed the metal-ceramic restoration using both systems, we compared the results and determined which system is more reliable and precise. Results: Described color-matching systems are, compared with the traditional shade guides, a major contribution to more aesthetic dental restorations. Based on the analysis of the tooth color, we made a metal-ceramic bridge in the sector of incisors from 12-22. In the end we compared the final results of achieved color from both systems. Discussion and conclusion: The use of a spectrophotometer, as well as a white balance gray reference card, significantly increases the aesthetic level of dental restorations. Described systems are easy to use, however, using the spectrophotometer is less time consuming. From the point of view of aesthetics white balance gray reference card is a better choice when making more complicated metal-ceramic restorations.
