Background and Objective: One of the most concerns about the use of implant treatments is bacterial leakage between the fixture and abutment at the connection. The aim of this study was to evaluate the bacterial leakage rate at the interface of ITI fixtures and ITI, DIO and OSSTEM solid abutments. Materials and Methods: Thirty ITI fixtures were divided into three groups (n=10) based on t...
a 48 year old patient was candidate for anterior mandibular reconstruction by 2 fixtures of branemark implant. residual infection lead to removal of one of the implants from the extracted tooth socket. afterwards, 2 fixtures of bonefit was inserted adjacent to previously placed branemark implants and final prosthesis were loaded in a joint cemented and screwed design.

The problem addressed in this paper is the decision problem of determining if a set of multi-dimensional rectangular boxes can be orthogonally packed into a rectangular bin while satisfying the requirement that the packing should be guillotine cuttable. That is, there should exist a series of face parallel straight cuts that can recursively cut the bin into pieces so that each piece contains a ...
In magnetic abrasive finishing (MAF), abrasive grains as a tool move on surface and can remove chip from surface of work piece. In this study AL 6061 tube was considered as the work piece and the effect of finishing parameters such as gap distance between tube and poles, rotational speed of tube, abrasive ration and finishing time on surface roughness was investigated. The mixture of ferromagne...
