Uvod: Pri pacientih, ne glede na starost, pogosto prihaja do izgube ali prekomerne obrabe zobnega tkiva, kar se kasneje nadomešča z zobnimi in drugimi nadomestki, sprva pa se preostalo zobno strukturo zaščiti s provizoriji oz. začasnimi zobnimi nadomestki. Ti v obdobju do dveh let pomagajo vzpostaviti normalno govorno in žvečno funkcijo, hkrati pa zagotavljajo normalen videz. Z razvojem sodobnih tehnologij in napredkom v razvoju sodobnih materialov je mogoča hitra začasna oskrba zob na različne načine. Namen: Namen diplomskega dela je pregled literature sodobnih aditivnih in subtraktivnih tehnologij in materialov, ki so primerni za izdelavo provizorijev, ter na podlagi tega ugotoviti in med seboj primerjati razlike in podobnosti v načinu izdelave, času izdelave, barvi, estetiki in trajnosti posameznih provizorijev, izdelanimi z DLP tehnologijo in s tehnologijo rezkanja ter izdelati protetični izdelek. Metode dela: V uvodnem delu je bila uporabljena deskriptivna metoda s pregledom tuje literature.. V praktičnem delu smo v laboratoriju pod nadzorom mentorja izdelali zgornji in spodnji začasni mostiček po aditivni metodi (DLP) in subtraktivni metodi (rezkanje). Rezultati: V rezultatih smo primerjali lastnosti teh provizorijev. Poudarek smo dali na način in čas izdelave začasnih mostičkov, primerjali smo barvo, estetiko ter nekatere lastnosti uporabljenih materialov. Razprava in zaključek: Ugotovili smo, da je potreba po provizorijih velika. Poznamo različne načine izdelave provizorijev, z napredkom sodobnih tehnologij ter s pojavom vse sodobnejših materialov pa bodo provizoriji v prihodnosti hitreje in kvalitetnejše izdelani. Trenutno dosegajo zadovoljive estetske standarde, ne glede na način izdelaveV prihodnosti bi se znalo zgoditi, da se izboljšata tesnilna funkcija in natezna trdnost, ter da pridobijo na trajnosti. Introduction: In patients, regardless of age, there is often a loss or excessive wear of dental tissue, which is later replaced by prosthetic replacements. Initially the remaining dental structure is protected by provisional or. temporary dental replacements. These help to restore normal speech and chewing function for up to 2 years, and they ensure a normal appearance. The development of modern technologies and advances in the development of modern materials enable various ways of a rapid temporary care of teeth. Purpose: The purpose of this diploma work is to review the literature of modern additive and subtractive technologies and materials suitable for the manufacture of provisionals. Based on this the purpose is to identify and compare the differences and similarities in the method of manufacture, time, colour, aesthetics and durability of individual provisionals made with DLP technology and milling technology and to make a prosthetic product. Methods: In the introductory part, a descriptive method with a review of mainly foreign literature on the topic of the diploma work was used. In the practical part, the upper and lower temporary bridges were made in the laboratory under the supervision of a mentor by using the additive method (DLP) and the subtractive method (milling). Results: In the result part the properties of made provisionals were compared. The emphasis was placed on the method and the time of making the temporary bridges. The colour, aesthetics and the properties of the materials used were also compared. Discussion and conclusion: We have found out that the need for provisionals is quite high. There are various ways of making the provisionals. With the progress of modern technologies and the appearance of different modern materials, provisionals will be made faster and they will be of better quality. Currently, they meet satisfactory aesthetic standards, regardless the method of manufacture. In the future their sealing function and tensile strength might be improved, and they might gain in durability. |
