AB  - Daily progress of dentistry, especially in the field of prosthodontics is introducing new materials and technologies. With the increasing need for aesthetically acceptable and non-metal materials, it came to development and improvement of ceramic materials and computer based systems (CA). The patient came in order to compensate the missing left lateral incisor. Since the adjacent teeth are brushed and the print was taken, casted model has been scanned using 3Shape D800 laboratory scanner. Dental restoration has been designed using 3Shape DentalSystem Premium software and the available tools. After completing the virtual design, the data are sent to the program responsible for CAM Zenotec® mini CAD/CAM device. As a result, the compensation with the full morphology was obtained without the need for finishing works.
AB  - Stomatologija, posebno stomatološka protetika svakodnevno napreduje uvođenjem novih materijala i tehnologija. Kako se javlja sve veća potreba za estetski prihvatljivim i bezmetalnim materijalima, došlo je do razvoja i unapređenja keramičkih materijala i računarima podržanih sistema (CA). Pacijent se javio radi nadoknade nedostajućeg levog bočnog sekutića. Pošto su susedni zubi zbrušeni i uzet otisak, izliven je model koji je skeniran pomoću 3Shape D 800 laboratorijskog skenera. Zubna nadoknada je dizajnirana pomo ću 3Shape DentalSystem Premium softvera korišćenjem raspoloživih alata. Nakon završenog dizajna virtuelni podaci su poslati u program odgovoran za CAM Zenotec® mini CAD/CAM uređaja. Kao rezultat, dobijena je nadoknada pune morfologije bez potrebe za dorađivanjem.

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  - Otpornost na koroziju je jedna od karakteristika koju poseduju stomatološke legure koje trebaju biti postavljene u usnoj duplji. Neželjene reakcije tkiva gingive i parodoncijuma sa stomatološkim legurama može biti uzrokovano efektima oslobođenih metalnih elemenata. Efekat korozije stomatološke Co- Cr -Mo legure ispitana je ICP MS prema EN ISO 10271 i EN ISO 22674 . Co- Cr stomatološke legure Remanium GM 800 + ( Dentaurum Ispringen , testirano u Nemačkoj u veštačkoj pljuvački tokom 7 dana na 37º C. Otkriveni su oslobođeni metali Nekion 300Ks ICP MS ( Perkin Elmer , SAD ). Rezultati su pokazali veoma slabo oslobađanje metala, Cr i Mo , daleko ispod dozvoljenih nivoa. ICP -MS može smatrati veoma pouzdan metod za ovakvo istraživanje .

AB  - Introduction. Double telescopic crowns are connecting elements of partial dentures and are considered to be prosthetic devices of high aesthetic and biological value. Their basic drawback is the assessment of retention force value which has to be strong enough to balance the opposite forces but, nevertheless, must not result in harming the periodontal tissue of retention teeth while taking the denture off. The retention force is the highest immediately after the denture's construction and is progressively declining until the end of the 'settling in phase', i.e. until the retention force value becomes well-established. Aim of the study was the measurement of the overall retention force of completed telescopic dentures and a survey of 'settling in phase' duration. Methods. The measuring was conducted on 20 telescopic dentures consisting of 2, 3 or 4 telescopic crowns made of gold alloy type IV and executed by dynamometer. Results. An optimal retention force was detected in only 37% of telescopic dentures. An insufficient retention force was observed in 16%, while in the remaining 47% an excessive force was detected. In the largest number of dentures (35%) the settling in phase began after 33 cycles, which shows that this phase takes on average 10,6 days. Conclusion. The 'settling in phase', during which retention force becomes stabilized, is completed in the first ten days after the delivery of the completed telescopic denture.
AB  - Uvod. Dvostruke teleskop krune predstavljaju vezne elemente parcijalne proteze i smatraju se zubnim nadoknadama visokih estetskih i bioloških vrednosti. Njihov osnovni nedostatak predstavlja procena veličine retencione sile, koja mora biti dovoljno velika da uravnotežava suprotne sile a da sa druge strane, prilikom skidanja, ne dovodi do oštećenja parodontalnog tkiva zuba nosača. Retenciona sila je najveća odmah po izradi proteze i ona progresivno opada sve dok se ne završi tzv. 'faza uhodavanja', odnosno dok vrednost retencione sile ne postane ustaljena vrednost. Cilj istraživanja bio je merenje ukupne retencione sile gotovih teleskop proteza i ispitivanje vremenskog trajanja 'faze uhodavanja'. Materijal i metod. Merenja si vršena na 20 teleskop proteza, koje su u svom sastavu imale 2, 3 ili 4 teleskop krune izrađene od legure zlata tip IV. Merenja su vršena pomoću dinamometra. Rezultati. Kod samo 37% teleskop proteza registrovana je optimalna retenciona sila. Kod 16% registrovana je nedovoljna retenciona sila, dok je kod ostalih 47% registrovana prekomerna retenciona sila. Kod najvećeg broja proteza (35%), faza uhodavanja nastupila je nakon 33 ciklusa, što znači da je potrebno u proseku 10,6 dana za 'fazu uhodavanja'. Zaključak. 'Faza uhodavanja' tokom koje dolazi do ustaljenja retencione sile u proseku se završava u okviru prvih deset dana nakon predaje završene teleskop proteze.

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.

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).

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.
