Abstract

Uvod: Začasna totalna proteza ali imediatna totalna proteza je snemni zobni nadomestek, ki se izdela takoj po ekstrakciji vseh zob. Uporablja se za vzdrževanje videza pacienta in kot kirurška opornica, ki pokriva vdolbine po ekstrakciji, pomaga pri celjenju ran in zaščiti mesto ekstrakcije. Izdelava preizkusne proteze je prvi digitalni korak pri digitalni izdelavi totalne proteze ter omogoča določitev okluzije, višine griza in oblike, barve ter velikosti zob, kar bi pri tradicionalni izdelavi določili z griznimi šablonami in dodatnim obiskom v ordinaciji. Izdelava preizkusnih protez se začne z računalniškim oblikovanjem v programski opremi in nadaljuje z računalniško podprto izdelavo. Pomaga zmanjšati klinične obiske, poenostavi celoten postopek izdelave protez, skrajša čas zdravljenja in izboljša natančnost dokončnih protez. Tehnologija CAD/CAM se nanaša na digitalno oblikovanje in izdelavo. S programsko opremo CAD načrtujemo geometrijo, obliko in lastnosti predmeta, medtem ko se za izdelavo uporablja programska oprema CAM. Proces izdelave CAM pa lahko vključuje aditivno ali dodajalno tehnologijo in subtraktivno ali odvzemalno tehnologijo. Dodajalne tehnologije, ki se uporabljajo v zobozdravstvu, med drugim vključujejo selektivno lasersko taljenje, stereolitografijo, ekstrudiranje termoplastov, digitalno obdelavo svetlobe in zaslon s tekočimi kristali. Namen: Namen diplomskega dela je predstaviti dodajalne tehnologije, ki se uporabljajo v zobozdravstvu, s poudarkom na stereolitografiji. Posvetili smo se snemni protetiki ter predstavili digitalno izdelavo začasne in preizkusne proteze. Metode dela: Pri teoretičnem delu diplomskega dela smo uporabili deskriptivno metodo. Pregledali smo strokovno literaturo v angleškem jeziku, in sicer spletne znanstvene članke, revije in knjige. Praktični del smo izvedli v zobnem laboratoriju skupaj z mentorjem. S 3D-tiskalnikom smo natisnili monolitno totalno protezo iz belega akrilata, da bi služila kot preizkusna proteza pri preizkusu skupaj s pacientom. Kasneje smo jo karakterizirali z barvami Optiglaze, da bi služila kot začasna totalna proteza. Rezultati: V rezultatih prikazujemo postopek izdelave začasne oziroma preizkusne totalne proteze. V programu 3Shape smo protezo oblikovali, nato pa jo iz svetlobno polimerizirajočega polimera uspešno izdelali s stereolitografijo. V diplomskem delu je predstavljen celoten potek izdelave izdelka, podprt s slikovnim gradivom. Razprava in zaključek: Sodobne tehnologije se v zobozdravstvu vse več uporabljajo. Trenutne inovacije in njihov razvoj v digitalnem zobozdravstvu so uspešno privedli do izdelave totalne proteze s tehnologijo CAD/CAM, za katero se odloča vse več zobnih laboratorijev, saj prihrani ogromno časa, izdelki pa so precizni in kakovostno narejeni. Pričakuje se, da se bo aditivna tehnologija še naprej izboljševala, kot se je subtraktivna tehnologija v svojih zgodnjih fazah. Ker je tiskalnik – v primerjavi z rezkalnim strojem – manjši, cenejši, hitrejši, natančnejši in okolju prijaznejši, saj je poraba materiala bistveno manjša, ima tehnologija tiskanja potencial za uporabo na vseh zobozdravstvenih področjih, tudi v snemni protetiki.

Secondary title: Production of temporary total denture with stereolithography
Secondary abstract: Introduction: A temporary total denture or immediate total denture is a removable dental prosthesis that is made immediately after the extraction of all teeth. It is used to maintain the appearance of the patient and to provide a surgical splint that covers cavities after extraction, aids in wound healing and protects the extraction site. Making a trial denture is the first digital step in making a total denture and allows you to determine the occlusion, the height of the bite and the shape, color and size of the teeth, which in the case of traditional production would be determined with bite templates and an additional visit to the doctor's office. The production of trial dentures begins with computer-aided design in software and continues with computer-aided production. It helps reduce clinic visits, simplify the entire process of making dentures, save treatment time and improve the accuracy of the final total denture. CAD/CAM technology refers to digital design and manufacturing. CAD software is used to design the geometry, shape and properties of an object, while CAM software is used for manufacturing. The CAM manufacturing process, can among others include additive technology and subtractive technology. Additive technologies used in dentistry include selective laser melting, stereolithography, fused deposion modeling, digital light processing, and liquid crystal display. Purpose: The purpose of the thesis is to present additive technologies used in dentistry, with an emphasis on stereolithography. We focused on removable prosthetics and presented the digital fabrication of temporary and trial denture. Methods: We used a descriptive method in the theoretical part of our diploma work. We reviewed professional literature in English obtained from online scientific articles, journals and books. The practical part was performed in the dental laboratory together with the mentor. Using a 3D printer, we printed a monolithic total prosthesis made of white acrylate to serve as a trial prosthesis in the experiment, later we characterized it with inks to serve as a temporary prosthesis. Results: In the results, we show the process of making a temporary and trial total denture. We designed the prosthesis in the 3Shape program, and then successfully produced it from light-curing polymer with the help of stereolithography. The diploma work presents the entire course of work on the manufacture of the product, supported by a pictorial presentation. Discussion and conclusion: Modern technologies are increasingly used in dentistry. Current innovations and their development in digital dentistry have successfully led to the production of removable dental prostheses using CAD/CAM technologies, which are being chosen by more and more dental laboratories, as they save a lot of time, yet the products are precise and of high quality. Additive technology is expected to continue to improve, just as subtractive technology did in its early stages. Since the printer, unlike the milling machine is smaller, cheaper, faster, more accurate and more environmentally friendly, since the consumption of material is significantly lower, the printing technology has the potential to be used in all areas of dentistry, including removable prosthetics.
