OBJECTIVE The objective of this study is to evaluate the use of tetracycline in a patient with peri-implantitis. BACKGROUND Tetracycline is widely used in regeneration procedures owing to its positive effect with bone graft material, regeneration of extraction socket bone and its traditional antibacterial effect. However, there have been limited reports on bone graft procedures combined with ...

We investigated the changes in surface roughness of retrieved femoral components in 18 men and four women at revision knee surgery. The mean age at revision was 68.4 years and the mean period of implantation was for 55.6 months. Eighteen implants were retrieved for aseptic loosening and four for infection. The surface changes in the articulating areas were inspected visually and the roughness (...

This paper deals with the improvement of material surface state friction stir welding paths modified in situ by plastic deformation through ball burnishing. The metallurgical and topological states materials joined this technique are typically detrimental to ulterior performance workpiece, it is believed that burnishing can improve these enhance functioning. study divided into two phases. first...

Abstract The surface integrity of the material is predominant necessity a component to perform efficiently in varying working conditions. To improve workpiece secondary finishing processes are being performed. This work attempts propose realistic cryogenic slide burnishing condition for improvement integrity. was performed by novel tool on 17–4 precipitation hardenable stainless steel. experime...

The design configuration of the nozzle has a vital role in performance measures machining processes. However, parameter optimizations are primary considerations published works. This study optimizes parameters to minimize environmental impacts and enhance surface quality for diamond burnishing (DB) operation. considered energy efficiency (ED), noise emission (NE), total height profile roughness...
