20.500.12556/RUL-183274 Izdelava kovinskega mostička s kompozitno slojeno faseto in polnokompozitnega mostička s tehniko rezkanja diplomsko delo Fabrication of a metal bridge with a composite layered veneer and a full composite bridge using the milling technique diploma work Uvod: Cilj vsake protetične oskrbe je zagotoviti optimalno funkcionalnost in estetski videz. V sodobnem času postajata estetski videz in minimalna invazivnost postopkov vse pomembnejša dejavnika. Kompozit je smolnat material, obarvan kot zob, ki se v zobozdravstvu uporablja za različne namene. Gre za vsestranski material, ki ga je mogoče oblikovati ter prilagoditi naravni barvi in obliki zoba, kar zagotavlja bolj estetski rezultat. Kompoziti so na makroskopski ravni iz dveh ali več različnih materialov. Sestavljeni so iz matice, utrjevalne faze in dodatka za vezavo teh dveh faz. Ambarino je nov in napreden material v zobni protetiki z izjemnimi lastnostmi, kot so večja elastičnost, vzdržljivost, manjša krhkost ter optimalno razmerje med polimeri in keramiko. Modul elastičnosti je ključnega pomena, saj določa sposobnost materiala, da absorbira učinke žvečenja. To omogoča, da se restavracija pod pritiskom upogne in prilagodi, kar zmanjšuje tveganje za zlome in odkruške pri vseh vrstah restavracij. Namen: Namen diplomskega dela je pregled obstoječe strokovne literature o izdelavi kovinskega mostička s kompozitno slojeno faseto in polnokompozitnega mostička s tehniko rezkanja. Primerjamo in opisujemo tudi postopek izdelave teh vrst zobnih mostičkov. Cilj je predstaviti ključne faze izdelave, prednosti in slabosti posameznih vrst mostičkov ter njihovo praktično uporabo v zobni protetiki. Poudarek je na tehnologijah in metodah, ki se uporabljajo pri izdelavi. Metode dela: V teoretičnem delu diplomskega dela smo uporabili deskriptivno metodo, ki vključuje pregled in analizo strokovne literature o zobni protetiki, ki smo jo pridobili v spletnih virih z iskalnikom Google Scholar. Glavni vir informacij so bili članki, objavljeni v različnih znanstvenih revijah, in strokovne knjige. Analizirali smo obstoječe vire o materialih in postopkih izdelave. V praktičnem delu diplomskega dela smo v laboratoriju izdelali dva mostička. Pri obeh mostičkih smo za modelacijo uporabili program Exocad. Prvega smo nato rezkali iz hibridnega materiala Ambarino v rezkalni enoti, ogrodje drugega pa natisnili s tehnologijo SLM in ga nato slojno fasetirali s kompozitnim materialom. Rezultati: V laboratoriju smo izdelali dva mostička s tehnologijo CAD/CAM. Kovinsko ogrodje prvega mostička smo izdelali s tehnologijo SLM, na ta mostiček smo potem v slojih nanašali kompozit. Drugi mostiček smo izrezkali iz hibridnega materiala Ambarino in ga dokončno obdelali. Razprava in zaključek: Po končani izdelavi obeh mostičkov smo ugotovili, da je čas izdelave polnokompozitnega mostička krajši kot izdelava mostička s kovinskim ogrodjem. Kovinsko ogrodje s kompozitno faseto zagotavlja boljšo trdoto. Prav tako je izdelava kovinskega ogrodja veliko krajša zaradi sistema CAD ali sistema modeliranja v programu Exocad, saj se čas modeliranja in izdelave skrajša vsaj za polovico. Introduction: The aim of any prosthetic treatment is to ensure optimal functionality and aesthetics. In modern dentistry, aesthetics are becoming increasingly important, as is the minimally invasive approach to procedures. Composite is a resin-based, tooth-colored material used for various purposes in dentistry. It is a versatile material that can be shaped and adapted to the natural color and form of the tooth, thus providing a more aesthetic result. Composites are composed of two or more different materials at the macroscopic level. They consist of a matrix, a reinforcing phase, and an additive that bonds these two phases. Ambarino is a new and advanced material in the field of dental prosthetics, offering remarkable properties such as higher elasticity, durability, reduced brittleness, and an optimal ratio of polymers to ceramics. The modulus of elasticity is crucial, as it determines the material’s ability to absorb the forces of mastication. This allows the restoration to bend and adapt under pressure, thereby reducing the risk of fractures and chipping in all types of restorations. Aim: The purpose of this thesis is to review existing professional literature on the fabrication of a metal framework bridge with a composite veneered surface and a full-composite bridge using milling techniques. Additionally, the study aims to compare and describe the manufacturing processes of these types of dental bridges. The goal is to present the key stages of fabrication, advantages and disadvantages of each type of bridge, and their practical application in dental prosthetics, with an emphasis on the technologies and methods used. Methods: In the theoretical part of the thesis, a descriptive method was applied, including the review and analysis of professional literature in the field of dental prosthetics, sourced from online databases (Google Scholar), textbooks, and lecture notes. The main sources of information were scientific articles published in journals and specialized books. The analysis focused on materials and fabrication procedures. In the practical part, two bridges were fabricated in the laboratory. For both cases, the design was modeled using Exocad software. The first bridge was milled from the hybrid material Ambarino, while the framework of the second bridge was printed using SLM technology and subsequently layered with composite material. Results: Two bridges were successfully fabricated using CAD/CAM technology. The framework of the first bridge was produced with SLM technology and veneered with composite in layers. The second bridge was milled from the hybrid material Ambarino and finished through subsequent processing. Discussion and Conclusion: The fabrication of the full-composite bridge was found to be faster compared to the bridge with a metal framework. However, the metal framework with composite veneering provides greater hardness. Moreover, the use of CAD systems or modeling in Exocad significantly shortens the production time of the metal framework, reducing both modeling and fabrication time by at least half. diplomska dela laboratorijska zobna protetika kompoziti tehnologija CAD/CAM Ambarino diploma theses laboratory dental prosthetics composites CAD/CAM technology Ambarino true false false [K.
