dc.description.abstractU savremenoj stomatologiji, ugradnja dentalnih implanata se smatra standardnom procedurom. Ipak, bez obzira na dugu praksu i primenu, u nekim slučajevima dolazi do prekida terapije. Jedan od razloga neuspeha terapija su prevelike vrednosti deformacija koje nastaju u kosti prilikom opterećenja dentalnih implanata. Na vrednosti deformacija koje nastaju u okolini implanta, znatno utiče geometrija implanata, odnosno njegov dizajn. Trenutno ne postoji standardna eksperimentalna metoda za ispitivanje uticaja dentalnog implanta na okolnu strukturu, odnosno ispitivanje njegove karakteristike prenosa opterećenja. Predmet istraživanja ove teze je analiza postojećeg stanja i razvoj nove metodologije za standardno ispitivanje prenosa opterećenja različitih tipova dentalnih implanata. Razvijena su dva eksperimentalna modela na bazi polimetil metakrilata, kao i dva numerička modela. Za izradu modela kalupa primenjena je metoda trodimenzionalne štampe. Za merenje deformacija i pomeranja, korišćena je optička, bezkontaktna metoda, trodimenzionalna korelacija digitalnih slika. Pomoću razvijenih eksperimentalnih i numeričkih modela, ispitan je uticaj primene pravih abatmenta i abatmenata pod uglom, uticaj nagiba implanta, kao i promene prečnika i dužine dentalnih implanata, na prenos opterećenja. Ispitan je uticaj geometrije tri različita dentalna implanta na akrilatni model, takođe tokom aksijalnog opterećenja. Prikazana metodologije ima za cilj da obezbedi standardnu pripremu uzorka koja će biti ekonomičnija, i brža u odnosu na numeričke analize, i klinička ispitivanja. Na ovaj način je moguće dobiti uvid u uticaj geometrije dentalnih implanata. Dodatno, ova metoda omogućava lakše poređenje uticaja geometrijskih karakteristika, velikog broja dostupnih dentalnih implanata, na raspodelu deformacija na noseću strukturu.sr
dc.description.abstractIn dental practice, dental implant placement is considered to be a standard procedure. However, in some cases, dental implant failure occurs. One of the reasons for this is overloading the bone which surrounds the dental implant. One of the most influencing factors that contribute to dental implant overload is dental implant designs. Currently, there is no standard experimental procedure for analysis of influence of dental implant design on load transfer characteristics. The subjects of this thesis is to the present a novel methodology for analysis of dental implant load transfer characteristics. Two experimental models were developed from polymethyl – methacrylate, and two numerical models. 3D printing technology was used in order to fabricate moulds for experimental samples. For contactless strain and displacement measurement, three-dimensional digital image correlation was used. Experimental and numerical models were used in order to analyse the effect of straight and angled abutment, influence of implant inclination, as variation of dental implant length and diameter, on their load transfer characteristics. Additionally, influence of three different dental implant designs on the acrylate model were analysed during axial loading. Goal of this methodology is to present relatively simple preparation of experimental models, which is more affordable and less time consuming when compared to numerical models or clinical trials. In this way, it is possible to acquire an insight into influence of dental implant design. Additionally, this method would enable easier comparison of geometrical characteristics, for large number of available dental implants, on strain distribution on the surrounding structure.en
