finite element analysis of the effect of superstructure materials and loading angle on stress distribution around the implant
statement of problem: a general process in implant design is to determine the reason of possible problems and to find the relevant solutions. the success of the implant depends on the control technique of implant biomechanical conditions. objectives: the goal of this study was to evaluate the influence of both abutment and framework materials on the stress of the bone around the implant by usin...
متن کاملcontent analysis of l1 and l2 writing textbooks and the perception analysis of university professors on the influence of english writing expertise on the persian in an efl context
the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...
an investigation of three types of tooth implant supported fixed prosthesis designs with 3d finite element analysis.
tooth/implant supported fixed prostheses may present biomechanical design problems, as the implant is rigidly anchored within the alveolus, whereas the tooth is attached by the periodontal ligament to the bone allowing movement. many clinicians prefer tooth/implant supported fixed prosthesis designs with rigid connectors. however, there are some doubts about the effect of attachment placement i...
متن کاملInfluence of prosthesis material on stress distribution in bone and implant: a 3-dimensional finite element analysis.
A 3-dimensional finite element analysis was conducted to assess stress distribution in bone, implant, and abutment when gold alloy, porcelain, or resin (acrylic or composite) was used for a 3-unit prosthesis. A unit force was applied axially and then buccolingually to the center of the pontic. For gold and porcelain, similar maximum equivalent stress was found in each part of the models. In alm...
متن کاملPeriodontal ligament influence on the stress distribution in a removable partial denture supported by implant: a finite element analysis
OBJECTIVES The non-homogenous aspect of periodontal ligament (PDL) has been examined using finite element analysis (FEA) to better simulate PDL behavior. The aim of this study was to assess, by 2-D FEA, the influence of non-homogenous PDL on the stress distribution when the free-end saddle removable partial denture (RPD) is partially supported by an osseointegrated implant. MATERIAL AND METHO...
