Abstract
Uvod: Svetovno prebivalstvo se stara, s tem pa se povečuje potreba po protetični rehabilitaciji. Kljub današnjemu razvoju tehnologije in priljubljenosti zobnih vsadkov je zaradi raznih kontraindikacij pri fiksni oskrbi in finančnih zmožnosti pacientov mogoča zgolj snemnoprotetična oskrba. V tem primeru je primerno zasnovana snemna delna proteza s kovinsko bazo edina izbira za obnovitev izgubljenih zob in s tem gnatološke funkcije. Namen: Namen diplomskega dela je pregled dodajalnih tehnologij v zobnem laboratoriju ter opis in strokoven prikaz postopka izdelave kovinske baze s stereolitografsko tehnologijo. Na podlagi tega želimo opredeliti, ali so dodajalne tehnologije primerne za izdelavo kovinske baze za kakovostno oskrbo pacienta. Metode dela: V teoretičnem delu diplomskega dela je metoda deskriptivna. Glavni vir informacij so članki v strokovnih znanstvenih revijah in strokovne knjige. Literaturo smo našli s pomočjo knjižnic in strokovnih baz, kot so Cobiss, PubMed, Medline, Web of Sciense ter Google učenjak, ter vsebuje domače in tuje strokovne prispevke v angleškem jeziku. V praktičnem delu smo v laboratoriju pod nadzorom mentorja izdelali kovinsko bazo ter tako predstavili potek izdelave kovinske baze z računalniško podprtim oblikovanjem in stereolitografijo. Rezultati: V našem primeru smo z digitalno tehniko laserskega zajemanja podatkov površino virtualnega modela natančno podvojili in rekonstruirali. Kovinsko bazo smo izdelali na virtualnem modelu z dobrim prileganjem na izvorni mavčni model. S stereolitografijo smo uspešno izdelali polimerni vzorec kovinske baze. Vse podrobnosti polimernega vzorca smo po postopku precizijskega litja natančno podvojili v kovini. Kovinsko bazo smo dokončali in spolirali s tradicionalnim postopkom v zobnem laboratoriju, nato pa ovrednotili na izvirnem mavčnem modelu. Ocenili smo, da se izdelek kakovostno prilega skladno s priporočeno prakso. Razprava in sklep: Glede na trenutni trend bo potreba po protetični oskrbi s kovinsko bazo še vedno velika. Pri zagotavljanju kakovostne oskrbe pacienta s kovinsko bazo in hkratnem zagotavljanju tržne prednosti laboratorija kažejo dodajalne tehnologije izjemen potencial. Predpogoj za to pa je dobro usposobljen laboratorijski izvajalec, ki s svojim strokovnim znanjem in poznavanjem dodajalnih tehnologij izvedbo lahko omogoči.

Title:Additive technology in dental prosthetics with presentation of metal framework manufacturing : diploma work
Abstract:
Introduction: Along with global aging, the need for prosthetic rehabilitation is increasing. Despite the current technology development and the popularity of dental implants, the oral healthcare is often limited to removable prosthesis, due to various contraindications and shortage of financial means. In this case, an appropriately designed removable partial prosthesis with a metal framework is the only choice for the restoration of lost teeth and hence the gnathological function. Purpose: The purpose of the diploma work is to review the extant additive technologies in the dental laboratory, and to describe and professionally demonstrate the process of manufacturing a metal base by using the stereolithographic production technology. Upon this basis, it is necessary to determine whether the additive technologies are suitable for the manufacture of a metal base for the quality care of patients. Methods: A descriptive research method was used in the theoretical part of the diploma work. The main sources of information were the articles in professional scientific journals and professional books. The literature was searched in libraries and professional databases Cobiss, PubMed, Medline, Scopus, Web of Science and Google Scholar. It includes domestic and foreign professional sources, mainly in the English language. In the practical part, a metal framework was created in the laboratory under the supervision of a mentor. Thus, the process of manufacturing a metal framework by using a computer-aided design and stereolithography is presented. Results: The digital model of laser data capture was accurately duplicated and reconstructed by the surface of the virtual model. The metal framework was built on a virtual model with adequate adaptation to the original gypsum model. By using stereolithography, the polymeric sample of the metal base was successfully manufactured. All details of the polymeric sample were precisely duplicated in metal by the precision casting process. The metal base was completed and polished using the traditional dental laboratory procedure and evaluated on the original plaster model. According to the recommended practice, the product was assessed to be of good quality. Discussion and conclusion: According to the current trends, the need for prosthetic care with a metal framework will continue to be high. In providing quality care for patients with a metal framework and the market competitive advantage, the additive technology has an exceptional potential. A prerequisite for a successful prosthetic oral care is a well-trained laboratory employee, with their expertise and knowledge of additive technologies.
