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  - 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  - Dental-implant overload can cause bone resorption. Load-transfer characteristics of dental implants are affected by their macro-design parameters. The goal of this study was to experimentally analyse the load-transfer characteristics of different dental implants, using polymethyl-methacrylate blocks. Three polymethyl-methacrylate blocks were created, with dimensions of (68 x 25 x 9) mm. Three dental implants, Nobel empty set3.5 mm x 15 mm, Strauman empty set4.1 mm x 10 mm and Strauman empty set4.8 mm x 12 mm. were placed in separate blocks. The samples were supported by a three-point-bending set-up and loaded with an axial force of 600 N. The 3D digital image correlation method was employed for strain and displacement measurements. The highest displacement and von Mises strain values were found for Strauman empty set4.1 mm x 10 mm (p  lt  0.05), 0.186 mm and 0.596 %, respectively. The sample of Nobel empty set3.5 mm x 15 mm showed the lowest strain values. The sample of Strauman empty set4.8 mm x 12 mm (p > 0.05) had similar strain values as Nobel empty set3.5 mm x 15 mm. The load transfer during axial loading was primarily affected by the size of the implant contact surface. The displacement and strain values in the implant vicinity may provide an insight into the effect of dental-implant design on the load transfer.

The goal of this study is to present a novel experimental approch for the analysis of effect od dental implant geometry on the surrounding structure strain values. A bone block model, with dimensions of 68x25x9 mm, was made from polymethyl-methacrylate. 3D printed block mold also provided a fixture for vertically placed Strauman ø4.0x12 mm. The sample was loaded in a three-point bending setup. The axial force of 600 N was applied on the dental implant. The Digital Image Correlation method was used for strain and displacement measurement. The highest von Mises strain of 0.7 % is located in the area of implant neck. The maximum displacement value in loading direction was 0.466 mm. Surface strain and displacement are correlated with implant geometry. This experimental methodology can be utilized to estimate dental implant load transfer characteristics.

AB  - Strain analysis in the vicinity of the dental implants were the subject of many research papers. In this study, new experimental method was employed for strain determination in the surrounding area of the axially loaded dental implant, which was embedded in the resin block. This studies can improve understanding of strain distribution, and its possible effects on the surrounding structure. Dental Implant Branemark with dimensions of 14 x 3.75 mm was immersed into rectangular block of polymethil methacrylate in vertical position. Implant was distanced 2 mm and 4 mm from the block sides, and they were named as the surface 1 and surface 2, respectively. Axial load, in the range of 0 - 500 N, was applied using Universal testing machine Tinius Olsen. Digital Image Correlation method was used for measuring deformation. Results were presented in the form of horizontal and vertical strains. Horizontal strains were mostly tensile, with maximum value of 0.3 % on the bottom of the surface 1. This values decreased in the upper area of the block side. Vertical compressive strain were 2-3 times higher on the surface 1, when compared to the surface 2, with maximum values of 0.7 % located on the bottom of the surface 1, and 0.3 % on the bottom of the surface 2. Resin block models could be used for determination of strain distribution under axially loaded implants. Greatest strain concentration were located under the implants apex, in the bottom area of the block. It was concluded that, in this region, strain values decreased linearly with increase of distance from the implants surface.

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.
