- Release of calcium ions: allows formation of mineralized tissues.
- Highly alcaline: prevents bacterial growth.
- Low solubility: may be used directly on pulp and periapical tissues.
- Compressive strength: 44.2 MPa – may be used as base for restorations.
- Expansion after hydration: seals cavities completely.
- Setting time (15 minutes): may be used in single appointment.
- Radiopaque: allows radiographic control.
- Biocompatibility: may be used directly on living tissues.
- New formation of cement: only dental material with this capacity.
- Remineralization of dentin: allows formation of biologic barrier.
- Biologic sealing of perforations: complete healing of periapical tissues.
White MTA has less iron oxide in its composition. This substance is the responsible for the darker color of the Gray MTA. Such reduction in the levels of iron oxide does not interfere with the great properties of the cement MTA.Which are the indications of MTA?
- Treatment of root canal perforation
- Treatment of furcation perforation
- Treatment of root canal resorption
- Retrofilling in periapical surgeries
- Direct pulp capping
- Intracoronal barrier during tooth bleaching
- Apical plug
The consistency of MTA is different when compared to conventional dental materials. Its application may be performed with insertion spatulas, amalgam carriers or instruments specially designed for MTA handling (e.g., MTA Carrier and MAp System). MTA should never be used with a Lentulo spiral because it needs to be directly placed in the area to be repaired.Why is the setting time of MTA Angelus faster than of the other brands?
Since 2002, the setting time of MTA Angelus was modified from 2.5 hours to 15 minutes.
This reduced setting time is exclusive of Angelus. The concentration of calcium sulfate, which is the substance responsible for the long setting time, was decreased. MTA Angelus allows final restorative treatment in the same clinical appointment of MTA insertion.
MTA does not have a proper consistency (flow) for final root canal filling. Also, after its
setting, removal would be extremely difficult if reentry is necessary.
A super treatment for accidents and endodontic complications.Description
Bioceramic Reparative Cement.Recommendation
Treatment of root canal and furcation perforations. Sealing of internal resorption. Surgical treatment of root perforation due to internal resorption. Reverse filling in periapical surgery. Pulp capping. Pulpotomy (removal of affected coronal pulp to preserve vitality of remaining pulp tissue). Apexigenesis (induction of root development in vital teeth with an inflamed coronal pulp). Apexification (induction of formation of a mineralized barrier at the root tip of young permanent teeth with incomplete root development and a necrotic pulp).Characteristics
