Background: Resin cements are widely used for cementation of FRC posts, but their bond strength can be influenced by cement type and cementation technique. The aim of this study was to determine the effect of type of resin cement and cementation technique on the bond strength of fiber posts. Methods: Forty five extracted mandibular premolars with a minimum roo...

BACKGROUND The increasing number of revision knee arthroplasty result in the more frequently use of a constraint implant but results from previous reports are difficult to interpret. The purpose of this study was to compare the long-term outcomes of superficial cemented versus metaphyseal cemented in revision total knee arthroplasty with a condylar constrained arthroplasty. METHODS The study ...

BACKGROUND Glenoid component survival is critical to good long-term outcomes in total shoulder arthroplasty. Optimizing the fixation environment is paramount. The purpose of this study was to compare two glenoid cementing techniques for fixation in total shoulder arthroplasty. METHODS Sixteen cadaveric specimens were randomized to receive peg-only cementation (CPEG) or full back-side cementat...

counties (Torrent et al., 1980), and in soils formed in late The morphologic development of soils on marine terraces is a function of terrace age and geomorphic evolution. In this study, inter­ relationships between terrace landscape evolution and pedogenic sil­ ica cementation were investigated. Soil morphology, micromorphol­ ogy, selective dissolution, penetration resistance, and hydraulic co...

PURPOSE In this study, we aimed to evaluate the amount of marginal gap with two different substructure materials using identical margin preparations. MATERIALS AND METHODS Twenty stainless steel models with a chamfer were prepared with a CNC device. Marginal gap measurements of the galvano copings on these stainless steel models and Co-Cr copings obtained by a laser-sintering method were made...
