BACKGROUND Patients undergoing cemented hip hemiarthroplasty may develop bone cement implantation syndrome (BCIS) which is a leading cause of intraoperative complications. The purpose of this study was to evaluate cardiovascular changes during cemented hip hemiarthroplasty in elderly patients. METHODS Cemented hip hemiarthroplasty was performed on 72 patients with femoral neck fracture. All p...

Dental cements are designed to retain restorations, prefabricated or cast posts and cores, and appliances in a stable, and long-lasting position in the oral environment. Resin-based cements were developed to overcome drawbacks of nonresinous materials, including low strength, high solubility, and opacity. Successful cementation of esthetic restorations depends on appropriate treatment to the to...

Niobium (Nb)-based alloys have been extensively used in the aerospace field owing to their excellent high-temperature mechanical properties. However, inferior oxidation resistance severely limits application of Nb-based a high-temperature, oxygen-enriched environment. Related scholars studied protection niobium alloy and pointed out that surface coating technology is ideal for solving this prob...

The aim of the study was to assess the effect of commonly used intravertebral anesthesia on bone cement implantation syndrome (BCIS) in aged patients undergoing hemiarthroplasty.The medical records of 1210 aged patients receiving hemiarthroplasty under intravertebral anesthesia were retrospectively reviewed. Anesthesia charts for all patients were reviewed for central venous pressure, mean arte...

Despite excellent outcomes with cemented tibial components in total knee arthroplasty, it still is debated whether the tibial stem should be cemented and what the optimal tibial stem design should be. Proponents of full cementation of the tibial stem and component state that better short-term and long-term component fixation is achieved when full cementation is used. Advocates for surface cemen...

OBJECTIVES To compare the finger pressure applied by dentists during cementation and to examine the effect of gender and time of day on finger pressure. METHODS Fifteen dentists (9 males, 6 females) formed a study group and 10 master dies in premolar shape and Turcom Cera all-ceramic crowns were prepared to measure the maximum finger pressure applied by dentists during cementation. The dentis...
