one of the important problems in earthquake geotechnical engineering is liquefaction phenomenon that happens in loose saturated granular soils. in this study, 11 boreholes from govanjik and dayalar area in downstream of sattarkhan dam collected and evaluated. results of research are showed that with assuming cementation in soils, liquefaction potential is weak to moderate than non-cemented cond...

AIMS/BACKGROUND The objective of this review was to define the impact of cementation mode on the longevity of different types of single tooth restorations and fixed dental prostheses (FDP). METHODS Literature search by PubMed as the major database was used utilizing the terms namely, adhesive techniques, all-ceramic crowns, cast-metal, cement, cementation, ceramic inlays, gold inlays, metal-c...

Ocean acidification describes the progressive, global reduction in seawater pH that is currently underway because of the accelerating oceanic uptake of atmospheric CO(2). Acidification is expected to reduce coral reef calcification and increase reef dissolution. Inorganic cementation in reefs describes the precipitation of CaCO(3) that acts to bind framework components and occlude porosity. Lit...

A one-year clinical study was performed on the efficacy of a bioactive dental cement (Ceramir C&B) with calcium aluminate and glass ionomer components. The study was performed on 38 crown and bridge abutments in 17 patients. Preparation parameters were recorded, as well as working-times, setting-times, and other handling characteristics. Baseline data were also recorded for gingival inflammatio...

BACKGROUND Reports of recurrence following restructuring of primary giant cell tumor (GCT) defects using polymethyl methacrylate (PMMA) bone cementation or allogeneic bone graft with and without adjuvants for intralesional curettage vary widely. Systematic review and meta-analysis were conducted to investigate efficacy of PMMA bone cementation and allogeneic bone grafting following intralesiona...

A leucite-reinforced glass ceramic material (IPS-Empress) which had shown for indirectly fabricated inlays and onlays an encouraging 2-year survival rate of 97.5% in a prospective clinical trial was introduced for clinical use at the University of Zürich. The aim of the present study was to assess the clinical behavior of IPS-Empress inlays and onlays with respect to possible fatigue phenomena ...

The clinical success of a restorative procedure of endodontically treated teeth depends on the cementation used to create a link between the restoration and the tooth. The retention of a post is a major factor influencing the survival of the restoration. Most clinical failures involving endodontically treated teeth reconstructed with posts are due to cementation failure of posts, whereas root f...

BACKGROUND One of few persisting problems of cemented total knee arthroplasty (TKA) is aseptic loosening of tibial component due to degradation of the interface between bone cement and metallic tibial shaft component, particularly for surface cemented tibial components. Surface cementation technique has important clinical meaning in case of revision and for avoidance of stress shielding. Degrad...

OBJECTIVE This study examined the fit of two types of all-ceramic single crowns and indirect composite resin full coverage crowns. MATERIAL AND METHODS Thirty intact human mandibular first premolars were selected for this study and prepared using a machine to standardize the dimensions and randomly divided into 3 groups. Slip cast (IC) (In-Ceram Zirconia, Vita Zahnfabrik), copy-milled zirconi...
