“…Secondary stability, on the other hand, depends upon osseointegration and bone formation. 4 It has been experimentally shown that implant surfaces that are rough have a higher percentage of implant bone contact (IBC) as compared to un-machined implants. 5 Thus, modifying the surface of the titanium implant is crucial in enhancing the osseointegration rate in addition to improving the stability of the implant.…”

The present work aims to evaluate the effect of various surface coatings of titanium dental implants by varying the friction coefficient (µ) at the interface between the dental implant and jawbone using finite element analysis (FEA) methods and to provide a comparative analysis between the various surface coatings and implant designs. An accurate model of the dental implant prosthetics consisting of the hard (cortical) and the soft (cancellous) bone, with the various titanium dental implant designs was modelled using a 3D CAD software, and the FE mesh model was generated using HyperMesh 13.0. Three coatings having different coefficient of friction values were selected: Titanium Nitride (TiN) with a friction coefficient of 0.19, Titanium Oxide (TiO2) with a friction coefficient of 0.30 and Zirconium Nitride (ZrN) with a coefficient of friction of 0.49. The non-linear static stress analysis was conducted under three different loading conditions (vertical, lateral and oblique loading) using a CAE solver. The present study showed that surface coatings with high friction coefficients generated lower stresses in the cancellous bone while generating higher stresses in the cortical bone. However, for dental implants having microthreads in their neck region, surface coatings with a high coefficient of friction generated lower stresses at the interface between the cortical bone and the implant. The FEA results indicate that selecting suitable surface coatings would significantly decrease the stresses developed at the bone-implant interface, and future studies should conduct in vivo trials to validate the FEA results obtained.

“…The use of synthetic polymers such as polylactic acid (PLA), polyglycolic acid (PGA) and poly (e-caprolactone) (PCL) has recently gained momentum due to their high mechanical strength. [2][3][4][5][6][7] PLA is one of the most important polymers used in bone tissue engineering applications due to biocompatible and biodegradable structure. This synthetic material is a polyamide group of polymer and is approved by the Food and Drug Administration (FDA).…”

Using a real bone is very important to find correct results for the biomechanical studies. However, it is very difficult to find the real bone and sometimes artificial bone models can be preferred instead of real bone. The aim of this study is to obtain an easy-to-manufacture, easy-to-customize and inexpensive method the artificial first metatarsal bone model that is similar material properties with the real bone. 3D printer technology was used to produce the artificial bone model. First metatarsal bone was modeled using MIMICS software to produce and determined the mechanical properties. The bone mechanical properties were calculated via MIMICS software using computer tomography images. 3D bone models were produced in different infill density and infill pattern to determine the real bone mechanical properties using 3D printer. The infill density of the bone model was adjusted as 20%, 40%, and 60%. Five different infill pattern types were used as grid, cubic, triangle, trihexagon, and gyroid. The produced models were subjected to torsional test and the elasticity modulus of all models were obtained. The results of the elasticity modulus of all produced (artificial) and modeled (calculated) bone were compared and the optimum bone model was obtained. The optimum infill density and infill pattern was determined as 40% and trihexagon, respectively.
