RESUMO

The bone or acrylic cement, also known for polymethylmethacrilate (PMMA), is a biomaterial used in surgeries. Used mainly in the fixation of prostheses, beyond the fulfilling and reconstruction of bone segments, the bone cement is placed in the empty spaces between the implant and the endosteal bone surface, hardening in little time and assuring the firm rank of prostheses when filling completely the empty space between the implantation and the bone. Quality of five marks of common bone cement (without antibiotic addition), of normal viscosity, commercialized in Brazil, was evaluated, being three of brazilian manufacture and two imported, in accordance with the parameters of norm ABNT NBR ISO 5833. They had become fullfilled it visual inspection of the components in order to verify requirements of appearance, packing and labelling, gauging of contents (mass and volume), and the following tests for attainment of the physical and mechanical properties of the material: stability of the liquid component, maximum temperature, setting time, doughing time, intrusion, compressive strength, bending modulus and bending strength. All the marks had been disapproved in the item 9.1-Labelling of the related norm, and two marks, being national and other imported, disapproved in the intrusion tests. In the too much verifications and assays all the evaluated marks had gotten resulted satisfactory.
