BACKGROUND Radiolucent lines about the glenoid component of a total shoulder replacement are a common finding, even on initial postoperative radiographs. The achievement of complete osseous support of the component has been shown to decrease micromotion. We evaluated the ability of a group of experienced shoulder surgeons to achieve complete cementing and support in a series of patients managed...

It has long been known that temperature during circulation and after cement placement is one of the most important parameters for slurry design and the success in cement production. Conventional cements and low density cement slurries usually take a long time to set and cannot provide significant compressive strength. Therefore, it is important to design appropriate low density cement slurries ...

OBJECTIVES To evaluate microleakage and marginal gaps in full cast crown restorations bonded with six different types of cementing agents. METHODS Sixty non-carious human premolars and molars were prepared in a standardized manner for full cast crown restorations. The mesial and distal margins were located in dentin, while the vestibular and palatal/lingual margins were located in enamel. Cro...

BACKGROUND AND PURPOSE Two contradictory cementing techniques (using an undersized stem versus a canal-filling stem) can both lead to excellent survival rates, a phenomenon known as the "French paradox". Furthermore, previous studies have indicated that the type of bone supporting the cement mantle may affect implant survival. To further evaluate the mechanical consequences of variations in cem...

BACKGROUND There has been controversy whether methylmethacrylate precoating of the cemented femoral stem is a solution for aseptic loosening or rather contributes to increased failure rates in cemented total hip arthroplasties. METHODS On a retrospective basis, we analyzed 76 primary hybrid total hip arthroplasties from 63 patients with precoated, cemented femoral stems between October 1990 a...

-The simple replacement technique of cement by fly ash in concrete does not produce a concrete with desirable early strength which is a significant parameter of present day emphasis of speedier construction. Increasing the amount of flyash replacement slows down the strength development at early ages. For effective mix proportioning of fly ash concrete, cementing efficiency factor has to be tak...

Cementing merupakan salah satu faktor terpenting dalam kegiatan pemboran yang dimana ini terbagi atas primary cementing dan secondary cementing. Squeeze adalah bagian dari penyemenan ulang rangka perawatan sumur, menutup zona perforasi sudah tidak produktif lagi. APR lapangan banyak di daerah Sumatra selatan dikelola oleh PT. Pertamina Hulu Rokan zona. 4. Metodologi digunakan pada penelitian be...

We present the medium-term results of hybrid total hip arthroplasties using pre-coated stems with a second-generation cementing technique. The 128 hips in 111 patients (18 men and 93 women) were followed up at a mean of 11 years after surgery. The mean age at the time of surgery was 61 years. Both components of one hip were removed at ten months after surgery for infection. None of the other 12...
