AB  - To determine if there are any differences in surface characteristics (surface roughness and contact angle) among different CAD/CAM materials indicated for fabricating implant-supported restorations, following all the material preparation protocols provided by the manufacturer. One-hundred forty-four specimens were divided into six groups: RBC (resin-based composite), PMMA (polymethyl methacrylate), PEEK (polyether ether ketone), ZP (zirconia polished), ZG (zirconia glazed) and CoCr4 (CoCr4 alloy). The experimental part included surface roughness (SR) and contact angle of water (WCA) analyses, fulfilled with atomic force microscopy (AFM) and scanning electron microscopy (SEM) view of surface topography. The data were analyzed using Kruskal-Wallis test with a Dunn's post hoc analysis, the correlation between measurements was tested using Spearman's rank correlation coefficient and all data were presented as mean ± SD. ZG specimens were significantly rougher compared to other groups (p ≤ 0.05). The WCA measurements revealed significantly lower mean values in ZG group (p ≤ 0.05), contrary to PEEK and CoCr4, where significantly higher mean values were observed, compared to other groups (p ≤ 0.05). There exist a moderate negative correlation between the SR and WCA (ρ =  0.41). AFM 3D and SEM 2D images presented more or less heterogeneous surface of all materials. There were statistically significant differences in surface roughness and contact angle among tested material groups. Moderate negative correlation was found between surface roughness and contact angle of tested material groups. The study gives us a better understanding of influence of physicochemical characteristics of investigated materials on their surface properties and provides useful knowledge for future researches in a view of material's behavior under in vivo conditions, when it comes to a question of features related to surface quality, such as microbial adhesion, corrosion, wear, biocompatibility and esthetics.

AB  - Uvod/Cilj Studija je sprovedena da identifikuje maksimalnu deformaciju proizvedenu u uzorcima sastavljenim od polimetilmetakrilata, Štrauman® implantata i tri vrste keramičkih sistema. Metode Korišćene su tri vrste eksperimentalnih modela izloženih spoljašnjem opterećenju od 100 N, 300 N i 500 N i analiziranih uz pomoć metoda korelacije digitalnih slika. Modeli su bili sastavljeni od itrijum-cirkonije, e. maks. litijum disilikatne i hibridnih keramika Vita enamik®, postavljenih na cilindrične dentalne implantantne sisteme Štrauman® (4 × 10 mm) sa abatmentima pod pravim uglom. Rezultati Značajne razlike su otkrivene u vrednostima deformacija između uzoraka sa različitim keramičkim krunicama (p = 0,000). Ovo podrazumeva da su vrednosti deformacija zavisne od tipa keramičkog materijala. Vrednosti deformacija su zavisne i od regiona interesa (p = 0,000). Primena ANOVA testa je omogućila da se uoči interakcija između nezavisnih varijabli, meterijala keramičkih kruna i regiona od interesa, gde je takođe nađena statistički značajna razlika (p = 0,046). Ova činjenica ukazuje na to da vrednosti deformacija zavise od različite kombinacije tipa keramičkog materijala i regiona interesa. Najveće vrednosti deformacija su nađene na modelu Z (0,383 ± 0,015) u apikalnom regionu, dok su najmanje vrednosti deformacija nađene na modelu E (0,303 ± 0,015) u regionu srednje trećine. Zaključak Izveštaj je pokazao maksimalne deformacije u apikalnim i marginalnim pravcima. Kada se razmatraju različite vrste keramika, najmanje deformacije su primećene ispod kruna Vita enamik®, dok je najveća deformacija pronađena u uzorcima sa krunama itrijum-cirkonija.
AB  - Introduction/Objective The study was conducted to identify the maximum strain generated in the samples composed of poly-methyl-methacrylate, Straumann® implants, and three types of ceramic systems. Methods Three types of experimental models were used, loaded by external load of 100 N, 300 N, and 500 N and analyzed using the digital image correlation method. The models were composed of yttriastabilized zirconia, e.max lithium disilicate, and Vita Enamic® hybrid ceramics, placed on the Straumann® cylindrical dental implant systems (4 × 10 mm) with straight abutments. Results Significant differences in strain values between samples with different crown material groups were detected (p = 0.000). This suggests that strain values were dependent on the type of crown material. Strain values were also affected by the region of interest (p = 0.000). Application of two-way ANOVA enabled testing of the interaction effect between two independent variables, crown material and region of interest, where a significant difference was also found (p = 0.046). This indicates that strain values were also influenced by different combinations of material type and region of interest. The highest strain values were found for Z (0.383 ± 0.015) in the apical region, and the lowest for E (0.303 ± 0.015) in the middle region. Conclusion The study shows maximum strain in the apical and marginal directions. When considered various all-ceramics, we noticed the minimum strain below Vita Enamics®, while the maximum strain was found in samples with yttria-stabilized zirconia crown.

AB  - The purpose of this study was to investigate the influence of the abutment angulation upon the strain distribution pattern for the vertical loading situation by means of the digital image correlation (DIC) method. In addition, to find the correlation between acrylic-layer thickness around implant body and surfaces strain induced by vertical loads. Two types of samples consisted of the Straumann (R) cylindrical dental implant system (4x10mm) with the SLActive (R) surface and the poly-methyl-methacrylate were used in this study. For strain analysis, the DIC system was used, manufacturer GOM. The optical deformation measurement system consists of special set of stereo cameras and lenses, and ARAMIS software (6.2.0, Braunschweig, Germany). Maximum von Mises strain was 0.30% in the sample with the straight abutment and 0.50% in the sample with the angled abutment. Minimum strain measured by Aramis was 0.01%, detected in the 6mm surface layer of the sample with straight abutment. According to results obtained by Aramis data processing, the 4mm surface layer indicated greater overall strain in apical direction with the strains of 0.18-0.50%, depending on the force intensity. Higher strain was noticed in the thinner surface layers. The angulated abutment induced higher strain in both surface layers than the straight abutment did.

AB  - It was the purpose of this study to determine and analyse strains in the bone of posterior mandible below the removable and fixed partial dentures using Digital Image Correlation Method. Dried mandible with shortened dental arch (Kennedy Class 1) was used in the experiment. The mandible model was prepared for accepting two types of restorations for bilaterally missing molars conventional therapy, and removable and fixed partial dentures were manufactured following standard prosthetic protocol. The models with prosthetic restorations placed in situ were subjected to loading of 50-300 N, and photographed using two digital cameras as part of the digital image correlation method equipment. Afterwards, the obtained data for strains within restored mandible during loading ciclus were analysed in the software Aramis and graphically presented. Percentage size of the mandible strains within the line section are from 0.14 to 0.19% for the removable partial denture experimental model and 0-0.14% for the fixed partial denture experimental model. The study has demonstrated that Digital Image Correlation method can be used to measure strain on the mandible surface and replacements during loading and that from biomechanical perspective both therapeutic modalities can be equally useful for the restoration of the mandible with bilaterally distal edentulous spaces.

abstract = "It was the purpose of this study to determine and analyse strains in the bone of posterior mandible below the removable and fixed partial dentures using Digital Image Correlation Method. Dried mandible with shortened dental arch (Kennedy Class 1) was used in the experiment. The mandible model was prepared for accepting two types of restorations for bilaterally missing molars conventional therapy, and removable and fixed partial dentures were manufactured following standard prosthetic protocol. The models with prosthetic restorations placed in situ were subjected to loading of 50-300 N, and photographed using two digital cameras as part of the digital image correlation method equipment. Afterwards, the obtained data for strains within restored mandible during loading ciclus were analysed in the software Aramis and graphically presented. Percentage size of the mandible strains within the line section are from 0.14 to 0.19% for the removable partial denture experimental model and 0-0.14% for the fixed partial denture experimental model. The study has demonstrated that Digital Image Correlation method can be used to measure strain on the mandible surface and replacements during loading and that from biomechanical perspective both therapeutic modalities can be equally useful for the restoration of the mandible with bilaterally distal edentulous spaces.",

AB  - Background: Understanding of the biomechanical consequences of the stresses generated to the supporting bone during occlusal loading is significant for improving the design and clinical planning process in partial edentulism therapy. Objective: The aim of this study was to analyse the distribution of strain and displacement on the partially dentate lower jaw rehabilitated with an partial denture (RPD) and to compare it to the strain and displacement distribution on a partially dentate lower jaw rehabilitated with a cantilever fixed partial denture (FPD). Material and methods: The experimental models were a partially dentate mandible with full-arch PFM crowns and RPD and a partially dentate mandible rehabilitated with a full-arch cantilever FPD. Strains and displacement were measured using the Digital Image Correlation Method. Results: Displacement values of the first experimental model ranged from 0.31 to 0.54 mm with strains from 1.35 to 2.34%. Analysis of the second experimental model results showed displacement values from 0 to 0.34 mm, while strains were in the range of 0-1.40%. Conclusion: Higher displacements and strains of bone tissue were observed below the RPD, especially in the region of the distal abutment and distal portion of the free-end saddle. Strains within bone and the bone-denture contact area were mostly influenced by the teeth and denture vertical displacement.

AB  - The aim of this study was to register and measure any deformation of mandible models under load. The method for full field measurement of strain is done by using the ARAMIS three-dimensional image correlation system. The system uses two digital cameras that provide a synchronized stereo view of the specimen and the results show the complete strain field during the tests. The biggest deformation values were just under the working force of the biggest intensity 500 N, and for the region of the lower second premolar the deformation is 625 mu m. The following study is presented that highlight the use of stereometric measuring system for modern research. It is shown that this measuring methodology can capture the trends of the experiments.
