zinc-phosphate cement Dental cement is used for: ● fixing of inlays, pin teeth, metallic, plastic, porcelain, porcelain fused metal crowns and prosthetic bridges;
● filling teeth to be crowned;
● as an isolating pad when filling teeth
Bactericidal is used in pediatric dentistry for milk teeth filling.
Dental cement is a universal improved zinc-phosphate dental cement with high mechanical compressive strengths: 90 MPa with a powder to liquid ratio of 1.5:1 (for fixing), 121 MPa with a powder to liquid ratio of 2:1 (for filling). The cement is obtained by mixing powder containing zincoxide and modifying agents with liquid represented by orthophosphoric acid of low activity. Film thickness for filling is no more than 25 μm. The presence of silver in bactericidal cement prevents the development of secondary caries and reduces the probability of emergence of the primary caries.
