It has been postulated that use of a larger femoral head could reduce the risk of dislocation after total hip arthroplasty, but only limited clinical data have been presented in third generation alumina bearings.
The investigators hypothesized that larger ceramic head group has a similar rate of dislocation and clinical results in smaller ceramic head group.

The primary objective of this study is to obtain implant survivorship and clinical outcome data for the commercially available Zimmer® Continuum™ Ceramic-on-Ceramic Bearing System when ...
The purpose of this study is to demonstrate non-inferiority of the Ceramic on Metal Total Hip when compared to a TRANSCEND® historical control group of patients with primary total hip rep...
Metal Ions levels of cobalt, chromium, and titanium in 40 patients preoperatively and at least 1 year status post total hip replacement with the Trident II Tritatnium system using an MDM l...
The main objective is to evaluate peri-implant hard and soft tissues's stability with the use of a ceramic implant (Implant Straumann®Pure Ceramic) during one year follow up.
Comparison of the functional result and speed of rehabilitation between two types of hip prostheses: primary ceramic-on-ceramic total hip replacement versus metal-on-metal hip resurfacing.
Mechanically assisted crevice corrosion (MACC) is a mechanism for trunnion damage in total hip arthroplasties (THAs). Retrieval studies have shown reduced MACC-related damage for ceramic heads compare...
BACKGROUND This study examined the effect of roughening of the root surface using an erbium-doped yttrium aluminum garnet (Er: YAG) laser on the binding strength of teeth undergoing root canal treatme...
The use of Ceramic-on-Ceramic (CoC) bearings in primary total hip arthroplasty (THA) is increasing and has been intensively analysed. This bearing plays a particularly relevant role in young, active p...
This study was performed to evaluate the effect of a lithium-disilicate spray-liner application on both the bond strength between zirconia cores and heat-pressed lithium-disilicate glass-ceramic venee...
Ceramic-on-ceramic articulation shows the lowest wear, with a low incidence of osteolysis. A small cup limits options regarding liner thickness and femoral implant size. The purpose of this study was ...
A type of porcelain used in dental restorations, either jacket crowns or inlays, artificial teeth, or metal-ceramic crowns. It is essentially a mixture of particles of feldspar and quartz, the feldspar melting first and providing a glass matrix for the quartz. Dental porcelain is produced by mixing ceramic powder (a mixture of quartz, kaolin, pigments, opacifiers, a suitable flux, and other substances) with distilled water. (From Jablonski's Dictionary of Dentistry, 1992)
A class of membrane lipids that have a polar head and two nonpolar tails. They are composed of one molecule of the long-chain amino alcohol sphingosine (4-sphingenine) or one of its derivatives, one molecule of a long-chain acid, a polar head alcohol and sometimes phosphoric acid in diester linkage at the polar head group. (Lehninger et al, Principles of Biochemistry, 2nd ed)
Cerebrosides which contain as their polar head group a glucose moiety bound in glycosidic linkage to the hydroxyl group of ceramides. Their accumulation in tissue, due to a defect in beta-glucosidase, is the cause of Gaucher's disease.
Glycosphingolipids which contain as their polar head group a lactose moiety bound in glycosidic linkage to the hydroxyl group of ceramide. Their accumulation in tissue, due to a defect in lactosylceramide beta-galactosidase, is the cause of lactosylceramidosis.
Cerebrosides which contain as their polar head group a galactose moiety bound in glycosidic linkage to the hydroxyl group of ceramide. Their accumulation in tissue, due to a defect in beta-galactosidase, is the cause of galactosylceramide lipidosis or globoid cell leukodystrophy.
Arthroplasty is a surgical procedure to restore the integrity and function of a joint. A joint can be restored by resurfacing the bones. An artificial joint (called a prosthesis) may also be used. Various types of arthritis may affect the joints. Osteo...
