Cemex is the bone cement designed by Tecres for joint implants. Cemex is a safe and reliable cement, with excellent mechanical performance and long-term clinical follow-up.
Bone cement is made up of polymers (powder) and a monomer (liquid); when the liquid component wets the surface of the powder it sets off a chemical reaction (known as polymerization).
An exclusive process patented by Tecres gives to the powder particles of Cemex a very smooth and uniform surface, making the cement very compact with extremely low porosity. The special powder of Cemex needs 30% less monomer than conventional bone cements found on the market.
With less monomer than any other cements on the market, Cemex is the acrylic resin with the lowest toxicity for anyone coming into contact with it
Every gram of monomer generates heat amounting to 130 Kcal. Cemex requires less liquid, so the maximum temperature reached at the end of the chemical reaction is substantially lower, thus preserving surrounding tissues
Shrinkage is the reduction in volume of the cement following its polymerization. It is directly proportional to the amount of liquid present. As the amount of monomer required is reduced by a third, shrinkage is also reduced, thus greatly improving implant fixation
Some antibiotics are heat-labile, but as Cemex only reaches quite a low temperature during polymerization, this reduces the risk of antibiotic degradation, thus ensuring effective release of the antibiotic
