RetroMTA is a hydraulic bioceramic material primarily used in vital pulp therapy and root repair. It distinguishes itself from traditional materials by not using Portland cement as a raw material. Instead, RetroMTA is a fine, hydrophilic powder that sets in the presence of water, forming a strong, impermeable barrier. This quality makes it particularly suitable for dental repair and vital pulp therapies.
Key Features
- Bioceramic Material: Composed of safe and biocompatible ceramic components.
- No Discoloration: RetroMTA is zirconia white, ensuring aesthetic integrity even in cases of blood contamination.
- Anti-bacterial Effect: It inherently resists bacterial growth, reducing the risk of infection.
- Quickly Wash-Out Resistant: Maintains its integrity when exposed to oral fluids.
- Initial Setting Time: Remarkably quick setting time of approximately 3 minutes (150 seconds), making it efficient for clinical use.
- pH Level: Initial pH of up to 12.5, decreasing to a neutral pH of 7.8–8.0 within four weeks, promoting a healthy oral environment.
Advantages in Dental Application
- Vital Pulp Therapy & Root Repair: Effective for pulp capping, pulpotomy, pulpectomy, apexification, and other vital pulp treatments.
- Aesthetic Applications: Ideal for treating and preventing discoloration, maintaining the natural appearance of teeth.
- Safety Profile: Free from heavy metals and demonstrates no cell toxicity within 48 hours.
- Biomineralization: Exhibits high potential for biomineralization, as indicated in ex vivo studies.
