“…Globally, the results obtained by these two models are clearly different, even if the remodeling period considered in the present paper is substantially shorter. The zone affected by remodeling as predicted by the current model is larger than that calculated by Dubois et al (2007). Also, important apposition was predicted by the former model, which is not confirmed by the present study.…”

Bone remodeling occurs in an adult's skeleton to adapt its architecture to external loadings. This involves bone resorption by osteoclasts cells followed by formation of new bone by osteoblasts cells. During bone remodeling, osteoclasts and osteoblasts interact with each other by expressing autocrine and paracrine factors that regulate cells' population. Therefore, changes in bone density depend on the amount of each acting cell population. The aim of this paper is to propose a model for the bone remodeling process, which takes into account the opposite activity of both types of cells. For this purpose, a system of differential equations, proposed by Komarova et al. (Bone 33:206-215, 2003), is introduced to describe bone cell interactions using parameters which characterize the autocrine and paracrine factors. Such equations allow us to determine how the autocrine and paracrine factors vary in response to an external stimulus. It is assumed that an equilibrium state can be obtained for values of stimulus near to some reference quantity. Far from this value, unbalanced activity of osteoblasts and osteoclasts is observed, which leads to bone apposition or resorption. The proposed model has been implemented into the finite element software ABAQUS to analyze the qualitative response of a bone structure when subjected to certain mechanical loadings. Obtained results are satisfactory and in accordance with the expected bone remodeling behavior.

“…Frequently implants must be placed in angled positions, complicating restoration using straight abutments. Angled abutments have been introduced to correct such cases [15]- [17]. The advent of angulated abutments has facilitated the parallelism of non-aligned implants thereby making the prosthesis fabrication easier.…”

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.
