“…Strain gauges require special surface preparations, provide only local measured results and must be in contact with the experimental sample. Photoelastic method requires the application of special birefractive materials and usually provides mostly qualitative measurements, while quantitative information's are lacking [52]. The idea behind this methodology is to experimentally analyse the effect of implant geometry on the displacements and von Mises strain values in its vicinity.…”

Deformations in the vicinity of dental implants are affected by their design and if threshold level of 0.3 % is surpassed, bone resorption could occur. 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.

“…Many methods have been used in dental implant studies to evaluate the biomechanical behavior of an implant‐supported prosthesis using photoelasticity, strain gages, and two‐ or three‐dimensional finite element analysis (FEA) . Three‐dimensional image correlation is one of these methods that have been commonly used in recent years for dental research . The current study design with an angled (30°) cyclic loading was used to implement “The International Organization for Standardization” portfolio (ISO 14801:2016) simulating the functional loading of an endosseous dental implant under “worst case” conditions.…”

Purpose: The behavior of implant-crowns fabricated from recently introduced CAD-CAM zirconia-reinforced lithium silicate ceramic (ZLS) or a hybrid ceramic containing resinreinforced glass network (HC) for strains around the implant platform is not well-known. A force absorption capacity of the latter has been claimed by the manufacturer. The aim of this study was to measure and compare recently introduced ZLS and HC with commonly used CAD-CAM implant crown materials for strain distribution around the implant platform. Methods: Four implants (Legacy 1; Implant Direct) were placed into a resin block. Zirconia abutments (Straight contoured stock abutment; Implant Direct) were torqued into the implant fixtures to support crowns that were milled from a virtual design using four different CAD-CAM materials (Vita Suprinity PC (ZLS), Vita Enamix (HC), IPS Emax, ZirCAD Zirkonzahn) (N = 20). The crowns were cemented with a resin cement, loaded and strain values were recorded. Three-dimensional digital image correlation (3D-DIC) was used to measure compressive and tensile strains around the implant platforms. The tensile and compressive strains were recorded for each test and first analyzed for equality of variance using Levene's test, and further tested using a 2-way ANOVA repeated measures analysis of variance (α = .05). Results: The data analysis showed no statistically significant effect of crown material on the generated strains (P > .05). Compressive strains were significantly higher than the tensile strains (P < .05). One of the HC crowns fractured during loading. Conclusions: Strains generated around implant platform when new generation CAD-CAM crown materials were used was similar to strains observed when CAD-CAM zirconia and lithium disilicate crowns were used. New generation crown materials did not have a significant load absorption effect to change or minimize the strains generated around the implant platform.
