“…To simulate the average masticator force in a natural loading on the implant, forces of 17.1 N, 114.6 N, and 23.4 N were applied respectively in lingual, axial, and mesiodistal directions [26]. In general, torque was generated by using two equal forces in magnitude, opposite in direction, applied to two opposite points on the diameter of the implant head.…”

Abstract-Implants should be placed, paralleled to adjacent tooth and be vertically aligned with axial forces. However, in many clinical instances, achieving this may be impossible due to deficiencies in alveolar bone. Clinically, many implant cases with different angulation over the lower posterior area have been found. Therefore, implants must be placed in angled positions, complicating restoration using straight abutments but on the other hand, angled abutments have been introduced to correct such cases. As regards, the major load in the anterior region is being entered by tongue to teeth and according to particular situation of lateral incisor tooth that has low space and also height limitation due to the existence of the sinus and nerves in maxilla and mandible, respectively, therefore this study is evaluated effects of angled installation of implants and use of the angled abutment. This paper was to discover desirable installation of implant and compare the relation between design angle abutment, angled installation of implants and load distribution at the implant bone interface with vertical abutment implantation and evaluate how could decrease stress and promote better stress distribution on surrounding bone of single-unit dental implants. Therefore, 26 solid models of the lateral incisor were built up and were transferred to mesh models in FEM to perform a stress analysis. In this study, static, dynamic and fatigue behaviors of the implant are investigated.Index Terms-Dental implant, FEM, angle abutment, angled installation.

“…This method works well in the very first step of teeth replenishing -treatment planning. Finite Elements Method supports the initial evaluation of the treatment success level, before the operation on the patient [7]. At the computerisation stage it is possible to eliminate the possible problems related to choosing the wrong implant geometry or unsuitable prosthetic crown overhangs size and shape.…”

Abstract. Dental implantology is one of burgeoning methods of teeth loss reconstruction. Because each patient is different, there are still many problems to be solved. One of them is occurrence of prosthetic crown overhangs. The overhangs increase the stress value and risk of the glue shattering, causing a crown fall out and requiring another implantologist's appointment. The aim of the study is to assess the stress value generated in the dental implant using Finite Elements Method and simplified models.

“…FEA method is common in the biomechanical study to predict implant performance. Prediction of macroscopic mechanical properties of porous structures using (FEA) can reduce amount of experimental works needed in tailoring special properties of porous implants hence allows researchers to predict stress distribution in the contact area of the implants with the bones by solving structural mechanics problems using numerical approximation [4]. Recent study shows that the effective elastic modulus of porous structure of CoCr biomedical grade alloy produced by selective laser melting (SLM) can be predicted using FEA [5] to some extent.…”

Abstract. In order to improve the stiffness characteristics of orthopedic devices implants that mimic the mechanical behavior of bone need to be considered. With the capability of Additive layer manufacturing processes to produce orthopedic implants with tailored mechanical properties are needed. This paper discusses finite element (FE) analysis and mechanical characterization of porous medical grade cobalt chromium (CoCr) alloy in cubical structures with volume based porosity ranging between 60% to 80% produced using direct metal laser sintering (DMLS) process. ANSYS 14.0 FE modelling software was used to predict the effective elastic modulus of the samples and comparisons were made with the experimental data. The effective mechanical properties of porous samples that were determined by uniaxial compression testing show exponential decreasing trend with the increase in porosity. Finite element model shows good agreement with experimentally obtained stress-strain curve in the elastic regions. The models prove that numerical analysis of actual prosthesis implant can be computed particularly in load bearing condition IntroductionThe major challenge in developing medical implant devices is to produce biocompatible alloys which possess good tensile and fatigue properties. The technique used to manufacture these alloy can markedly affect the mechanical and metallurgical properties of the resulting components [1]. Additive manufacturing (AM) was proposed as a novel candidate for the fabrication of customized biomedical implants with the cobalt alloys. Among them, is direct metal laser sintering (DMLS) which has been a high demand since it offers a lower time-to-market, a near-net-shape production, a higher material utilization rate, along with its ability to produce functional metallic parts with mechanical properties comparable to those in bulk materials [2]. From the previous studies, SLM has the potential of controlling porosities according to the capacity of providing different energy inputs by its processing parameters while in DMLS process all the parameters were constant. A study on cobalt chromium molybdenum (CoCrMo) powder using DMLS shown that minor porosity produced by the highest layer thickness, which provided a better particle packing. Thus thermal conductivity among the particles was enhanced and subsequently permitted successful densification, and finally removed or shrunk pores.Cobalt (Co) in CoCrMo alloys exhibits high corrosion resistance and has excellent wear resistance which makes Co, often employed as artificial joints and body implants. Co also shows stability of allotropic transformation at room and elevated temperatures. In biomedical applications, CoCrMo
