AB  - Background/Aim. There is limited published evidence on the cytotoxicity of 3D printed polymer materials for dentistry applications, despite that they are now widely used in medicine. Stereolithography (SLA) is one of the foremost 3D processes used in 3D printing, yet there are only a small number of resin materials reported to be suitable for medical applications. The aim of this study was to investigate, in vitro, the cytotoxic effect of the 3D printed resin in order to establish the suitability for its usage in dentistry and related medical applications such as surgical dental guides, occlusal splits and orthodontic devices. Methods. To examine the cytotoxicity of the 3D printed polymer-based epoxy resin, Accura® ClearVue™ (3D-Systems, USA), two cell cultures were used: mouse fibroblasts L929, and human lung fibroblasts MRC-5. The cell viability was determined by the Mosmann's colorimetric (MTT) test and the agar diffusion test (ADT). Results. Direct contact of the tested material with the ADT test showed nontoxic effects of tested material in any cell culture. The tested material showed no cytotoxic effect after 3 days of extraction of the eluate by the MTT, but mild cytotoxic effect after 5, 7 and 21 days on both cell lines. The cytotoxicity increased with increasing the time of the eluate extraction. Conclusion. The 3D printed polymer-based epoxy resin, Accura® ClearVue™ (3D-Systems, USA) is considered appropriate for making surgical dental implant guides according to the cytotoxic behavior. According to the mild level of cytotoxicity after the longer extraction periods, there is a need for further evaluation of biocompatibility for its application for the occlusal splints and orthodontic devices.
AB  - Uvod/Cilj. Malo je objavljenih dokaza o citotoksičnosti 3D štampanih polimernih materijala za upotrebu u stomatologiji, bez obzira na njihovu sve širu primenu u medicini. Stereolitografija (SLA) jedan je od najvažnijih 3D procesa koji se primenjuje za 3D štampu, ali postoji samo Mali broj materijala na bazi smola za koje je dokazano da su pogodni za medicinsku primenu. Cilj ove studije je bio da se ispita, in vitro, citotoksični efekat 3D štampanog polimera kako bi se utvrdila mogućnost za njegovu upotrebu u stomatologiji i srodnim medicinskim oblastima, kao što su hirurške dentalne vođice, okluzalni splintovi i ortodontski aparati. Metode. Da bi se ispitala citotoksičnost 3D štampanog polimera na bazi epoksi smole, Accura® ClearVue ™ (3D-Sistems, USA), korišc'ene su dve c'elijske kulture: fibroblasti miša L929 i humani fibroplasti pluc'a MRC-5. Vijabilnost c'elija utvrđena je Mosmannovim kolorimetrijskim testom (MTT) i testom difuzije agara (ADT). Rezultati. Direktan kontakt testiranog materijala ispitan pomoću ADT pokazao je da materijal nije imao citotoksičan efekat ni na jednu ćelijsku kulturu. Testitrani materijal je imao blag citotoksični efekat posle 5, 7 i 21 dana ekstrakcije eluata primenom MTT na obe ćelijske linije. Citotoksičnost je rasla sa produženjem vremena ekstrakcije eluata. Zaključak. 3D štampani polimer na bazi epoksi smole, Accura® ClearVue ™ (3D-Sistems, USA) se može smatrati pogodnim za izradu hirurških dentalnih implantnih vođica sa tačke gledišta njegovog citotoksičnog uticaja. Zbog pokazanih blagih citotoksičnih efekata nakon dužih ekstrakcionih perioda eluata potrebna su dalja istraživanja u oblasti biokompatibilnosti materijala da bi se taj polimer mogao koristiti za izradu okluzalnih splintova i ortodontskih aparata.

AB  - The purpose of this study was to evaluate color adjustment potential (CAP) of resin composites. Two shades of each of eight commercial resin composites and one control shade were evaluated. Visual (color competent observers, controlled conditions) and instrumental color evaluations (spectroradiometer, spectrophotometer) were performed. The data were analyzed by analysis of variance, Fisher's PLSD intervals for comparison of means, and Spearman's rank order correlation. Instrumental color adjustment potential (CAP-I) ranged from - 0.51 to 0.74, and corresponding Fisher's PLSD intervals were 0.1 and 0.05, respectively (p  lt  0.0001, power 1.0). Visual color adjustment potential (CAP-V) ranged from 0.10 to 0.78, and corresponding Fisher's PLSD intervals were 0.2 and 0.1, respectively (p  lt  0.0001, power 1.0). The greatest overall color shifting between test shades in isolation and the same shades surrounded by control shade were recorded for HRi ENA enamel, followed by Clearfil Majesty ES2. The highest visual CAP (blending) was recorded for Herculite Ultra, HRi ENA enamel, and Clearfil Majesty ES2. Within the limitation of the study, it was found that color adjustment potential (CAP) was composite and shade-dependent. Positive CAP was recorded both instrumentally and visually for majority of composites and shades. Overall, the measured color difference reduction associated with positive CAP was 31%, while the average visual CAP was 43%. Resin composites with pronounced color adjustment potential interact with surrounding dental restorations. Introduced CAP-V and CAP-I were indirect measurements of blending (optical illusion).

AB  - Development and improvement of 3D digitizing systems provide for the ability to digitize a growing number of materials and geometrical forms of greater complexity. This paper presents the application of 3D digitizing system using close range photogrammetry on the upper jaw cast in plaster in order to obtain its 3D model. Because of the low visual characteristics of gypsum, such as color and texture, many questions arise about the possibility of applying this particular method to this type of physical models. In order to overcome bad visual properties of gypsum, this paper analyzes the possibility of the photogrammetry method application supported by the projected light texture which is based on patterns in the form of noise-obtained mathematically modeled functions. In order to determine the selected image for light texture which gives the better results, an experiment was designed and carried out. Only two images were tested. One image is selected based on previous research and the other one was generated by the Matlab function for uniformly distributed random numbers. For validation and a comparative analysis of the results, an object of 3D digitization was generated with and without projected light texture. CAD inspection was applied for the analysis of the obtained 3D digitizing results. 3D model obtained by approved professional optical 3D scanner as a reference was used. The results in this paper confirm better accuracy of 3D models obtained with the use of light textures, but this approach requires additional hardware and setup adjustment for images acquisition.

AB  - Background/Aim. Dental impressions present a negative imprint of intraoral tissues of a patient which is, by pouring in gypsum, transferred extraorally on the working cast. Casting an accurate and precise working cast presents the first and very important step, since each of the following stages contributes to the overall error of the production process, which can lead to inadequately fitting dental restorations. The aim of this study was to promote and test a new model and technique for in vitro evaluation of the dental impression accuracy, as well as to asses the dimensional stability of impression material depending on the material bulk, and its effect on the accuracy of working casts. Methods. Impressions were made by the monophasic technique using the experimental master model. Custom trays with spacing of 1, 2 and 3 mm were constructed by rapid prototyping. The overall of 10 impressions were made with each custom tray. Working casts were made with gypsum type IV. Measurement of working casts was done 24 h later using a coordinate measuring machine. Results. The obtained results show that the working casts of all the three custom trays were in most cases significantly different in the transversal and sagittal planes in relation to the master model. The height of abutments was mainly unaffected. The degree of convergence showed certain significance in all the three custom trays, most pronounced in the tray with 3 mm spacing. Conclusion. The impression material bulk of 1-3 mm could provide accurate working casts when using the monophasic impression technique. The increase of the distance between abutment teeth influences the accuracy of working casts depending on the material bulk.
AB  - Uvod/Cilj. Otisak predstavlja negativ intraoralnih tkiva, čijim se izlivanjem u gipsu njihova morfologija prenosi ekstraoralno na budući radni model. Sa laboratorijskog aspekta izrade zubnih nadoknada, izlivanje tačnog i preciznog radnog modela predstavlja prvi i veoma bitan korak, pošto svaka sledeća faza doprinosi daljem povećanju greške tokom izrade, što za krajnji ishod može imati neodgovarajuću zubnu nadoknadu. Cilj istraživanja bio je da se ispitaju novi model i tehnika za in vitro procenu preciznosti zubnih otisaka, kao i da se odredi uticaj količine otisnog materijala na dimenzionu stabilnost otisaka i preciznost izrade radnih modela. Metode. Za uzimanje otisaka korišćena je monofazna tehnika otiskivanja. Individualne kašike sa međuprostorom od 1, 2 i 3 mm napravljene su aditivnom tehnologijom za brzu izradu prototipova. Sa svakom kašikom napravljeno je po 10 otisaka. Radni modeli izlivani su u gipsu tipa IV. Merenje radnih modela vršeno je nakon 24 sata na koordinatnoj mernoj mašini. Rezultati. Rezultati pokazuju da radni modeli napravljeni pomoću sve tri individulane kašike u transverzalnoj i sagitalnoj ravni značajno odstupaju od glavnog dela modela. Visina patrljaka je u većini slučajeva bila kao na glavnom modelu. Stepen konvergencije pokazao je određena odstupanja samo kod kašike sa međuprostorom od 3 mm. Zaključak. Monofazna tehnika otiskivanja i otisni materijal debljine od 1 do 3 mm obezbeđuju izradu preciznih radnih modela. Rastojanje između zubnih patrljaka utiče na preciznost izrade radnih modela u zavisnosti od količine otisnog materijala.

Otisak predstavlja negativ intraoralnih tkiva, čijim se izlivanjem u gipsu njihova morfologija prenosi ekstraoralno na budući radni model. Sa laboratorijskog aspekta izrade zubnih nadoknada, izlivanje tačnog i preciznog radnog modela predstavlja prvi i veoma bitan korak, pošto svaka sledeća faza doprinosi daljem povećanju greške tokom izrade, što za krajnji ishod može imati neodgovarajuću zubnu nadoknadu. Cilj istraživanja bio je da se ispitaju novi model i tehnika za in vitro procenu preciznosti zubnih otisaka, kao i da se odredi uticaj količine otisnog materijala na dimenzionu stabilnost otisaka i preciznost izrade radnih modela. Metode. Za uzimanje otisaka korišćena je monofazna tehnika otiskivanja. Individualne kašike sa međuprostorom od 1, 2 i 3 mm napravljene su aditivnom tehnologijom za brzu izradu prototipova. Sa svakom kašikom napravljeno je po 10 otisaka. Radni modeli izlivani su u gipsu tipa IV. Merenje radnih modela vršeno je nakon 24 sata na koordinatnoj mernoj mašini. Rezultati. Rezultati pokazuju da radni modeli napravljeni pomoću sve tri individulane kašike u transverzalnoj i sagitalnoj ravni značajno odstupaju od glavnog dela modela. Visina patrljaka je u većini slučajeva bila kao na glavnom modelu. Stepen konvergencije pokazao je određena odstupanja samo kod kašike sa međuprostorom od 3 mm. Zaključak. Monofazna tehnika otiskivanja i otisni materijal debljine od 1 do 3 mm obezbeđuju izradu preciznih radnih modela. Rastojanje između zubnih patrljaka utiče na preciznost izrade radnih modela u zavisnosti od količine otisnog materijala.",

AB  - Corrosion resistance is one of the characteristics that dental alloy should possess as it should be placed in the oral cavity. Adverse tissue reactions of the gingiva and the periodontium close to dental cast alloys may be caused by the effects of released metal elements. Corrosion effect of dental Co-Cr-Mo alloy was investigated by ICP MS according to the EN ISO 10271 and EN ISO 22674. Co- Cr dental alloy Remanium GM 800+ (Dentaurum Ispringen, Germany was tested in artificial saliva for 7 days at 37ºC. The released metals were detected by Nexion 300X ICP MS (Perkin Elmer, USA). The results showed that the metal release was very low for Co, Cr and Mo, far below the permitted levels. ICP-MS can be considered as very reliable method for such a research.

AB  - Development and improvement of 3D digitization methods in the last forty years, have enabled that virtual impression in dentistry becomes a reality. Unlike conventional impressions, which represent negative copies of prepared teeth and surrounding tissue, 3D digitization collects data on the coordinates of surface points and transfers them into digital form. Various working principles of 3D digitization methods were the reason, that in the framework of this reasearch to invstigate and compare the basic metrological characteristics of selected optical digitization devices. Based on the hypothesis, following goal of investigation were formulated: to establish whether there is a difference in the accuracy and precision between the optical digitization devices where the process of digitization based on various working principles and determine the degree of measurment uncertainty. The basis of this experiment is CAD inspection. CAD inspection was used to measure and analyze deviations between the CAD reference model and experimental CAD models. In this way is possibile to determine the precision and accuracy of the observed optical digital device. The experimental CAD models were generated by 3D digitization of the stone replica using Cerec® AC (Sirona, Germany), Cerec® In Eos Blue (Sirona, Germany), Trios (3 shape AS, Denmark), KaVo Everest (KaVo, Germany) and Sinergia Scan (Nobil - Metal, S.p.A. Italy) surface digitization devices. The CAD master model was generated by 3D digitization of the stone replica, using Atos III Triple Scan surface digitization device. Processing of the measured results included 2D and 3D analysis. The results of 3D analysis showed thet the highest level of precision in the proceeding of digitizing the right half of upper dental arch are present in Sinergia Scan, then follow KaVo Everest, Trios, Cerec®InEos Blue i Cerec®AC devices. The highest level of accuracy in the same procedure have Cerec®InEos Blue, follow the Sinergia Scan, Cerec®AC i KaVo Everest...
AB  - Razvoj i unapređenje metoda 3D digitalizacije u proteklih četrdeset godina, omogućio je da se ideja o primeni digitalnog otiska u stomatologiji pretvori u stvarnost. Za razliku od konvencionalnog otiska koji predstavlja kopiju zuba i okolnih tkiva u negativu, 3D digitalizacija je postupak u okviru koga se vrši prikupljanje podataka u vidu koordinata – tačaka i obavla njihovo prevođenje u digitalnu formu. Razlike u radnim principima postupaka 3D digitalizacije predstavljale su povod da se u okviru istraživanja ispitaju i uporede osnovne metrološke karakteristike odabranih uređaja za optičku digitalizaciju, koji se primenjuju u stomatološkoj praksi. Na osnovu postavljene hipoteze definisan je osnovni cilj istraživanja: utvrditi da li postoji razlika u preciznosti i tačnosti između uređaja za optičku digitalizaciju kod kojih je postupak digitalizacije zasnovan na različitim radnim principima i na osnovu toga proceniti stepen njihove merne nesigurnosti. Osnovu eksperimenta čini metoda CAD inspekcije, čijom primenom je moguće izvršiti kvantitativnu i kvalitativnu analizu izmerenih odstupanja uzoraka CAD eksperimentalnih modela u odnosu na CAD master model i na taj način utvrdi stepen preciznosti i tačnosti posmatranih uređaja. CAD eksperimentalni uzorci su nastali u postupku digitalizacije osnovnog modela od gipsa pomoću sledećih uređaja: Cerec®AC (Sirona, Germany), Cerec® InEos Blue (Sirona, Germany), Trios (3 shape AS, Denmark), KaVo Everest (KaVo, Germany) i Sinergia Scan (Nobil - Metal, S.p.A.

AB  - The paper presents a comparative study of the measuring values of the marginal gap related to the ceramic crowns made by dental CAD/CAM system using the replica technique and SEM. The study was conducted using three experimental groups, which consisted of ceramic crowns manufactured by the Cerec CAD/CAM system. The scanning procedure was carried out using three specialized dental 3D digitization systems from the Cerec family - two types of extraoral optical scanning systems and an intraoral optical scanner. Measurements of the marginal gap were carried out using the replica technique and SEM. The comparison of aggregate values of the marginal gap using the replica technique showed a statistically significant difference between the systems. The measured values of marginal gaps of ceramic crowns using the replica technique were significantly lower compared to those measured by SEM. The results indicate that the choice of technique for measuring the accuracy of ceramic crowns influences the final results of investigation.

AB  - CAD/CAM technology in dentistry offers high-end ceramic restorations, known for its quality, preciseness, swiftness and repeatability. However, some features are still human-dependent. A young female patient required smile enhancement, since suffering from colour change on three devitalized frontal teeth. After fiber post placement, teeth were prepared for metal-free restoration. Consequently, abutments were scanned using extraoral scanner (Sirona, InEos Blue; Beinsheim, Germany). CAD software (version 3.8) has been used to create three crown copings, with cut-back in the incisal region. After finalization of the virtual modeling, data file has been transferred to a milling unit (Sirona, MCXL, Beinsheim, Germany) that produced crown copings out of a ceramic block (IPS e.max CAD, Ivoclar Vivadent, Schaan, Liechtestein). Crowns were tried for the fit and occlusion in the so-called blue stage, after which final strength and shape has been achieved by thermal treatment in the ceramic furnace. Individualization has been done manually, creating special effect in the cut-back region. Crowns were cemented adhesively. CAD/CAM offers modern and relevant way of producing ceramic restorations, however, special effects still require manual adjustments.
AB  - CAD/CAM tehnologije u stomatologiji nude visoko kvalitetne keramičke zamene, poznate po kvalitetu, preciznosti, brzini izrade i ponovljivosti. Međutim neke opcije još uvek zavise od ljudske intervencije. Mlada pacijentkinja je imala zahtev za poboljšanjem osmeha, pošto je patila od promene boje na tri prednja nezdrava zuba. Posle instalacije vlaknene podloge, zubi su bili spremni za bez-metalnu reparaciju. Otisci su bili skenirani ekstraoralnim skenerom (Sirona, InEos Blue, Beinsheim, Nemačka). CAD softver (verzija 3.8) je korišćen za generisanje tri navlake. Po završetku virtuelnog modeliranja podaci su prebačeni na glodalicu (Sirona, MCXL, Beinsheim, Nemačka) koja je izradila navlake od keramičkih blokova (IPS-a, max CAD, Ivoclar Vivadent, Schaan, Lihtenštajn). Navlake su posle isprobane zbog procene naleganja i začepljenja u tzv. plavoj etapi, posle čega je konačno očvršćavanje i oblikovanje postignuto termičkom obradom u peći za keramiku. Individualno prilagođavanje je izvršeno ručno, sa izradom posebnog efekta u zadnjem delu. Navlake su cementirane adhezijom. CAD/CAM nudi moderan i važan način u izradi keramičkih implanta ali posebni efekti još uvek zahtevaju intervenciju čoveka.

AB  - Introduction. Inlay retained adhesive restorations present a conservative approach when a single tooth is missing in the posterior region. Material and methods. Twenty five restorations were included in the clinical study. Patient selection, preparation technique as well as denture fabrication followed current principles in this area. Patients were examined every 6 months over a 2 year examination period. Results were statistically analyzed. Results. The success rate for the first year comes to 91.1%, while cumulative success probability during the second year (24 months) was 86.6%. Furthermore, colour, texture and marginal staining were satisfactory during the observation period. Conclusion. Fibre-reinforced composite adhesive dentures are a tooth preserving, minimally invasive, aesthetic and reliable treatment option for single tooth replacement in the posterior area.

U kliničku studiju, uključeno je 25 adhezivnih nadoknada. Odabir pacijenata, principi preparacije, kao i tehnika izrade mostova urađeni su prema važećim standardima u ovoj oblasti. Pacijenti su praćeni na svakih 6 meseci tokom dvogodišnjeg perioda. Rezultati su statistički obrađeni. Rezultati. Uspešnost nadoknada u prvoj godini iznosi 91.1%, dok kumulativna uspešnost tokom druge godine (24 meseca) iznosi 86.6%. Takođe, ocena boje, teksture i marginalnog prebojavanja daje zadovoljavajuće rezulate tokom perioda praćenja. Zaključak. Kompozitne nadoknade ojačane vlaknima su minimalno invazivni, estetski i pouzdan način tretmana minimalne krezubosti bočnog segmenta denticije.
