Uvod: Zobna protetika je v zadnjih desetletjih doživela izjemen napredek, ki je spremenil način zobozdravstvene oskrbe. Zgodovinsko gledano, se je zobna protetika zanašala predvsem na materiale, kot so kovine, keramika in preprosti polimeri. Uporaba novih tehnologij pa je v zobozdravstvo privabila nove materiale, ki so v drugih panogah že bolj ali manj dobro poznani. Med drugimi so to sintetični polimeri iz družine PAEK. To so termoplastični materiali, ki so dobro kemično odporni in prenašajo visoke temperature. Član te skupine je tudi PEEK, ki se v medicini že nekaj časa uporablja kot sestavni del ortopedskih implantatov, v laboratorijski zobni protetiki pa je še precej neraziskan material. Namen: V diplomskem delu smo ugotavljali lastnosti in uporabo PEEK-a in njegovih kompozitov v laboratorijski zobni protetiki. Metode dela: Teoretični del diplomskega dela temelji na pregledu strokovnih člankov in druge strokovne literature predvsem tujih in nekaj domačih avtorjev, ki smo jih našli v podatkovnih bazah na medmrežju. Rezultati: Raziskali smo mehanske lastnosti (trdnost, trdoto, modul elastičnosti) in druge specifične fizikalne lastnosti PEEK-a ter jih primerjali z lastnostmi nekaterih drugih materialov, ki se uporabljajo v laboratorijski zobni protetiki, pa tudi PEEK-a s kompoziti. Poleg tega smo predstavili uporabo PEEK-a in njegovih kompozitov v laboratorijski zobni protetiki. Razprava in zaključek: Ugotovili smo, da imajo PEEK in njegovi kompoziti primerne mehanske lastnosti za uporabo v laboratorijski zobni protetiki. Zaradi mehanskih lastnosti, ki so podobne lastnostim kosti, je PEEK primeren za uporabo v snemni in fiksni zobni protetiki, pa tudi v čeljustni in zobni ortopediji in kot material za zobne implantate. Na podlagi opravljene analize in primerjave lastnosti PEEK-a in njegovih kompozitov z lastnostmi dentalnih materialov (kot so dentalne zlitine in keramika), ki se že dalj časa uporabljajo v zobni protetiki, smo ugotovili, da so PEEK in njegovi kompoziti zelo primerni za uporabo. Kljub temu je število študij o njegovi dolgoročni stabilnosti še vedno omejeno, zato je težko z gotovostjo napovedati, kako se ti materiali obnašajo po več letih uporabe.

Abstract

Introduction: Over recent decades, the field of laboratory dental prosthetics has experienced significant advancements, fundamentally reshaping dental care. Traditionally, dental prosthetics relied on metals, ceramics, and basic polymers. However, the integration of new technologies has introduced advanced materials from other industries into dentistry, particularly synthetic polymers from the PAEK family. These thermoplastic materials, renowned for their chemical resistance and high-temperature stability, have enhanced potential in dental applications. Among these, PEEK has already found use in medical implants but remains largely unexplored in laboratory dental prosthetics. Purpose: This thesis explores the properties and potential applications of PEEK and its composites in laboratory dental prosthetics. Methods: The theoretical framework is based on an extensive review of international and domestic scholarly articles, accessed through online databases. Results: In the results, we investigated the mechanical properties (strength, hardness, elastic modulus) and other specific physical properties of PEEK and compared them with the properties of some other materials used in laboratory dental prosthetics, as well as PEEK with composites. In addition, we presented the use of PEEK and its composites in laboratory dental prosthetics. Discussion and conclusion: We found that PEEK and its composites have suitable mechanical properties for use in laboratory dental prosthetics. Due to mechanical properties similar to those of bone, PEEK is suitable for use in removable and fixed dental prosthetics, as well as in orthodontics, and as a material for dental implants. Based on the analysis and comparison of the properties of PEEK and its composites with the properties of dental materials (such as dental alloys and ceramics), which have been used in dental prosthetics for a long time, we found that PEEK and its composites are very suitable for use. However, the number of studies on its long-term stability is still limited, making it difficult to predict with certainty how these materials will behave after several years of use.
