Uvod: Brezzobost je stanje, ki se najpogosteje pojavlja med starejšimi ljudmi. Pomeni odsotnost zob v zgornji in spodnji čeljusti, delimo pa jo na delno ali popolno. Glavna vzroka zanjo sta predvsem zobni karies in napredovala parodontalna bolezen. Popolno brezzobost lahko oskrbimo s totalno snemno protezo, ki je še vedno prva možnost pri rehabilitaciji brezzobosti. Izdelamo jo lahko na več načinov. Trenutno se še vedno najpogosteje uporabljata klasična metoda in brizgana metoda po sistemu Ivocap. Čedalje večji napredek kažeta tudi aditivna metoda s 3D-tiskom in subtraktivna metoda z rezkanjem. Namen: Namen diplomskega dela je opisati izdelavo totalne proteze na več načinov in izdelati protetični izdelek po eni izmed opisanih metod ter opraviti upogibne preizkuse materialov, za katere smo primerjali podatke o mehanskih lastnostih, ter ugotoviti, katere so prednosti in slabosti posamezne tehnike. Metode dela: V teoretičnem delu smo uporabili deskriptivno metodo. Proučili smo literaturo, ki smo jo našli na medmrežju, ob prebiranju strokovnih revij, knjig, člankov, diplomskih del in knjig v spletnih brskalnikih in v knjižnici Zdravstvene fakultete, ki so bili dosegljivi v letih 2019–2020. Literatura je bila v slovenskem, hrvaškem in angleškem jeziku. V praktičnem delu smo izdelali vzorce za upogibne preizkuse in protetični izdelek po eni izmed opisanih metod. Postopek smo slikovno prikazali. Rezultati: Prikazali smo postopek izdelave preizkušancev in rezultate upogibnih preizkusov. Opisana je tudi izdelava proteze z vroče brizganim akrilatom po metodi Ivocap. Postopek je slikovno prikazan. Razprava: Iz rezultatov upogibnih preizkusov smo ugotovili, da ima najboljše vrednosti vroče brizgani akrilat po metodi Ivocap. Zaključek: Nove tehnologije izdelave, kot sta rezkanje s sistemom CAD/CAM in tehnika 3D-tiska, kažejo velik potencial v prihodnosti laboratorijske zobne protetike. V večini kliničnih primerov protetične oskrbe s snemno totalno protezo pa je pri izbiri tehnike izdelave cena še vedno odločilna.

Izvleček

Introduction: Toothlessness is a condition that most commonly occurs among older people. It means the absence of teeth in the upper and lower jaw, and is divided into partial or complete. The main causes for it are mainly dental caries and advanced periodontal disease. Complete edentulousness can be provided with a total removable prosthesis, which is still the first option in the rehabilitation of edentulousness. It can be made in several ways. Currently, the classic method and the injection method according to the Ivocap system are still the most commonly used. The additive method with 3D printing and the subtractive method with milling are also showing increasing progress. Purpose: The purpose of the diploma work is to describe the manufacture of total dentures in several ways and make a prosthetic product by one of the described methods and perform bending tests of materials for which we compared data on mechanical properties, and determine the advantages and disadvantages of each technique. Methods of work: In the theoretical part we used a descriptive method. We studied the literature we found on the Internet while reading professional journals, books, articles, diplomas and books in web browsers and in the library of the Faculty of Health, which were available in the years 2019-2020. The literature was in Slovene, Croatian and English. In the practical part, we made specimens for bending tests and a prosthetic product according to one of the described methods. The process was illustrated. Results: We presented the manufacturing process of the test specimens and the results of the bending tests. The production of prostheses with hot sprayed acrylate according to the Ivocap method is also described. The procedure is illustrated. Discussion: From the results of bending tests, we found that hot-sprayed acrylate by the Ivocap method has the best values. Conclusion: New manufacturing technologies, such as CAD / CAM milling and 3D printing technology, show great potential in the future of laboratory dental prosthetics. In most clinical cases of prosthetic care with a removable total prosthesis, the price is still decisive when choosing the manufacturing technique.
