“…Load transfer at the bone-implant interface depends on: (1) The implant geometry and the design of implant abutment connection; (2) the loading protocol and the type of occlusion; (3) the number of implants and position; (4) the quality and quantity of the surrounding bone. [ 2 3 4 5 6 ]…”

Aims:The aim of the study was to evaluate the stress distribution pattern in the implant and the surrounding bone for a passive and a friction fit implant abutment interface and to analyze the influence of occlusal table dimension on the stress generated.Materials and Methods:CAD models of two different types of implant abutment connections, the passive fit or the slip-fit represented by the Nobel Replace Tri-lobe connection and the friction fit or active fit represented by the Nobel active conical connection were made. The stress distribution pattern was studied at different occlusal dimension. Six models were constructed in PRO-ENGINEER 05 of the two implant abutment connection for three different occlusal dimensions each. The implant and abutment complex was placed in cortical and cancellous bone modeled using a computed tomography scan. This complex was subjected to a force of 100 N in the axial and oblique direction. The amount of stress and the pattern of stress generated were recorded on a color scale using ANSYS 13 software.Results:The results showed that overall maximum Von Misses stress on the bone is significantly less for friction fit than the passive fit in any loading conditions stresses on the implant were significantly higher for the friction fit than the passive fit. The narrow occlusal table models generated the least amount of stress on the implant abutment interface.Conclusion:It can thus be concluded that the conical connection distributes more stress to the implant body and dissipates less stress to the surrounding bone. A narrow occlusal table considerably reduces the occlusal overload.

“…Von Mises stresses from occlusal loading are initially transferred from the implant to the cervical (crestal) bone, as a compact bone has a higher modulus of elasticity compared to spongious bone. 25,26 In the presented analysis spongious bone maximum stress was only 65.69 MPa.…”

Connecting implants with teeth is sometimes considered for the support of prostheses in partial edentulism, especially in periodontally compromised and surgical treated patients. The aim of this study is the presentation of a model of tooth–implant nonrigid fixation in comparison with implant–implant and implant–tooth rigid fixation by three-dimensional (3D) finite element analysis. As a model, a situation with a mandibular second premolar and two molars edentulism was selected. Two implantation options with three prosthetics designs were considered. The comparative analysis of stress and strain distribution values under vertical 100 and 200 N loading was performed. The highest peri-implant crestal bone stress distribution was observed in the model with the implant–tooth rigid fixation with 200 N vertical loading with results of 136.56 MPa. In the model with implant–tooth nonrigid fixation, the maximum strain value was observed in the tooth–connector zone and the stress distribution was higher in the connectors and the prosthesis pontic zone, with a maximal value of 27.77 MPa. The design of a tooth–implant fixed denture could be suggested as a method of choice for rehabilitation of the posterior edentulous segment in cases when only one distal implant could be installed. Further clinical research is required to obtain reliable validation data for the proposed method.

The purpose of this study is to shows the usefulness of dental implant. In this paper include different types of abutments, tier system and structure which is used in dental implant. In this study shows the types of connections of abutments.There are various types of stresses which reason to diseases related dental implant. Forces act initially on the neck of dental implant. There are many types of abutments which are used for fixation of crown. The main objective is to perform analysis of failure on dental implant and post. The more focus of this study on abutment. Objective is to provide alternative solution to overcome on failure due to infection, diseases which are comes after implant. This paper includes diseases. Failures of dental implants are frequently clinical problems. So there is need of analysis of abutment in dental implant is essential. Purpose of this study is analysis and process which used for evaluation of abutment and implant.
