Za poznavanje zbivanja u Domovinskom ratu na područjima zapadne Hrvatske
nezaobilazna je prosudba zapovijedanja i postupaka komandanta 13. riječkog
korpusa JNA general-potpukovnika Marijana Čada. ...General je sve do potpisivanja sporazuma s predstavnicima hrvatske vlasti u studenom 1991. dosljedno
izvršavao povjerene mu zadatke od strane nadređenih mu zapovjedništava JNA.
Zapovijedajući postrojbama na području Like i Gorskog kotara upravljao je borbenim djelovanjima postrojbi JNA i pobunjenih Srba, u okviru napadne operacije
na Republiku Hrvatsku u jesen 1991. godine. Izvlačenjem postrojbi 13. korpusa
s riječkog područja general Čad je ispunio svoj ratni zadatak te povrh svega očuvao svoja građanska prava u Republici Hrvatskoj. U javnom mnijenju je za mnoge ostao spasitelj grada Rijeke od ratnih razaranja. Razmatrajući slijed događaja
i pojedine manje poznate činjenice, u tekstu se nastojalo dati cjelovitu sliku i utemeljenu ocjenu njegove uloge, i odgovornosti u ratnim sukobima do potpisivanja
sporazuma o odlasku 13. korpusa iz Hrvatske.

Objectives
To present the results of guided bone regeneration (GBR) of atrophic edentulous ridges with customized CAD/CAM titanium meshes.
Material and methods
Forty‐one patients, presenting with 53 ...atrophic sites, were enrolled between 2018 and 2019. GBR was obtained with titanium meshes filled with autogenous bone chips and bovine bone mineral (BBM). After a mean of 7 months (range: 5–12 months), meshes were removed and 106 implants placed. After a mean of 3.5 months (range: 2–5 months), implants were uncovered and prosthetic restorations started. The outcomes were vertical and horizontal bone augmentation changes, biological complications and implant survival.
Results
Out of 53 sites, 11 underwent mesh exposure: eight of them were followed by uneventful integration of the graft, while three by partial bone loss. The mean vertical and horizontal bone gain after reconstruction was 4.78 ± 1.88 mm (range 1.00–8.90 mm) and 6.35 ± 2.10 mm (range 2.14–11.48 mm), respectively. At the time of implant placement, mean changes of initial bone gain were −0.39 ± 0.64 mm (range −3.1 to + 0.80 mm) and −0.49 ± 0.83 mm (range –3.7 to +0.4 mm), in the vertical and horizontal dimensions, respectively. Reduction of bone volume was significantly higher (p < .001 for both dimensions) in the exposed sites. The mean follow‐up of implants after loading was 10.6 ± 6.5 months (range: 2–26 months). The survival rate of implants was 100%.
Conclusion
Customized titanium meshes can represent a reliable tool for GBR of severely atrophic sites, with simplification of the surgical phases.
The accuracy of virtual interocclusal records has been evaluated, but clinical studies comparing the clinical output to the virtual design are lacking.
The purpose of this clinical study was to ...evaluate the agreement between the virtual occlusal scheme designed by a computer-aided design and computer-aided manufacturing (CAD-CAM) software program and the occlusal scheme obtained clinically on the definitive prosthesis assessed with articulating paper.
The virtual occlusal scheme design of 20 single monolithic crowns and their adjacent teeth were obtained using an intraoral scanning system (IOS) in 17 participants. These registrations were compared with conventional occlusal records obtained by applying articulating paper in 2 stages: first with 200-μm blue film and the second with 12-μm metallic red articulation tape. The analysis included both the quantity and the quality of the contacts of the conventional occlusal records referred to as the standard method. For accuracy analysis, virtual record sensitivity was calculated per crown as the percentage of true positive virtual contacts of the actual contacts identified by articulating paper. Specificity was also calculated as the percentage of true negative virtual contacts of the actual sites of clearance.
The virtual record sensitivity was 98.5 (95% confidence interval 96 to 100) for the crowns and 95 (95% confidence interval 85 to 100) for the adjacent teeth. The virtual record specificity was 88.6 (95% confidence interval 82.4 to 94.8) for the crowns and 82.6 (95% confidence interval 77.5 to 87.6) for the adjacent teeth. The agreement between the clinical and virtual contact intensities on the crowns was 83 (95% confidence interval 73 to 93) and 67.3 (95% confidence interval 56 to 78.7) for the adjacent teeth. The positive predictive value was 72.83 (95% confidence interval 60 to 86). The negative predictive value was 100% (95% confidence interval 100 to 100).
The intraoral scanning system provided clinically sufficient sensitivity and specificity for identifying the occlusal surface contacts of monolithic crowns. A slight decrease was detected in the system’s sensitivity and specificity in identifying contacts on adjacent teeth and a larger decrease identifying the intensity of these contacts.
The Dentsply Sirona CAD-CAM system intraoral scanner, design software program, and milling unit provide sufficient accuracy in designing and manufacturing single monolithic crowns in terms of the designed static occlusal scheme.
Self-adhesive resin cements (SARCs) are used because of their mechanical properties, ease of cementation protocols, and lack of requirements for acid conditioning or adhesive systems. SARCs are ...generally dual-cured, photoactivated, and self-cured, with a slight increase in acidic pH, allowing self-adhesiveness and increasing resistance to hydrolysis. This systematic review assessed the adhesive strength of SARC systems luted to different substrates and computer-aided design and manufacturing (CAD/CAM) ceramic blocks. The PubMed/MedLine and Science Direct databases were searched using the Boolean formula ((dental or tooth) AND (self-adhesive) AND (luting or cement) AND CAD-CAM) NOT (endodontics or implants). Of the 199 articles obtained, 31 were selected for the quality assessment. Lava Ultimate (resin matrix filled with nanoceramic) and Vita Enamic (polymer-infiltrated ceramic) blocks were the most tested. Rely X Unicem 2 was the most tested resin cement, followed by Rely X Unicem > Ultimate > U200, and μTBS was the test most used. The meta-analysis confirmed the substrate-dependent adhesive strength of SARCs, with significant differences between them and between SARCs and conventional resin-based adhesive cement (α < 0.05). SARCs are promising. However, one must be aware of the differences in the adhesive strengths. An appropriate combination of materials must be considered to improve the durability and stability of restorations.
