MTA is used for root canal perforation, root-end resection, apexification, pulp capping & pulpotomy.
- Ions Calcium Release: Enhances formation of mineralized tissues; provides biological seal of perforations and total repair of damaged periradicular tissues
- Biological action: Capable of inducing neoformation of periradicular cementum
- Easy to use: does not lose properties due to moisture of oral tissues
- High alkalinity: Bactericidal
- Biocompatible to oral tissues: Low inflamatory response
- Adequate compressive strength: Can be used as base restoration material
- More radiopaque than dentin and bone: Easy radiograph visibility
- Setting time of 15 minutes: Possibility of immediate restoration
- Treatment of perforations of root canal and furcation caused iatrogenically or by caries lesion.
- Via canal treatment of root perforation due to internal resorption.
- Surgical treatment of root perforation due to internal resorption.
- Periapical surgery with reverse filling.
- Pulp capping.
- Pulpotomy (removal of affected coronal pulp to preserve vitality of remaining pulp tissue).
- Apexogenesis (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).
DIRECTION TO USE
- Angelus MTA powder is mixed with distilled water using a sterile spatula and a glass slab.
- The content of cement is placed with the measuring scoop in the glass slab and must be mixed with the one drop of distilled water.
- Mix it for 30 seconds.
- The consistency of the cement after mixing, sandy and humid.
- The mixture can be easily applied using the amalgam carrier.
- Depending upon the application area, instruments such as burnishes and spatulas can also be used.
WHAT ARE THE MAIN PROPERTIES OF MTA? CHEMICALS:
- Release of Ca ions - allows the formation of remineralization tissue.
- Highly alkaline - inhospitable for bacterial growth.
- Low solubility - can be used directly on the pulp and periapical tissues.
- Compressive strength: 44.2 MPa - can be used as a base material.
- Hydration expansion - produces complete sealing of cavities.
- Setting time: 15 minutes - can be used in a single session.
- Radiopaque - allows posterior radiographic control (proservation).
- Biocompatibility - can be used directly on living tissues.
- New cement formation - the only dental material with this property.
- Dentin remineralization - formation of biological barrier.
- Biological perforation sealing - complete healing of periradicular tissues.
WHAT IS THE DIFFERENCE BETWEEN GRAY AND WHITE MTA?
The difference lies in the reduction in concentration of one of the components of MTA-Angelus, iron oxide, which is responsible for the gray color of the product. This reduction does not interfere with any of the properties of the MTA.
WHAT ARE THE INDICATIONS OF THE MTA?
- Treatment of root perforations and furcations.
- Sealer for internal and internal resorption communicating.
- Retrobutter in parendodontic surgery.
- Pulp capper in conservative pulp treatments.
- Apexification and apexigenesis inducer.
- Material for intracoronary barrier prior to tooth whitening.
- Apical plug.
HOW TO APPLY THE MTA?
MTA is a material of different consistency than conventional dental materials.
Its application can be carried out with instruments of use (MTA Angelus Applicator). It should never be used with Lentulus drills, as it needs to be inserted directly into the place to be repaired.
WHY IS THE SETTING TIME FOR MTA ANGELUS DIFFERENT THAN THAT OF COMPETITORS?
Angelus, since 2002, changed the setting time of the MTA, which was 2 and a half hours, reducing it to 15 minutes. This reduction in setting time is exclusive to Angelus. A decrease in the concentration of Calcium Sulfate was made, which leaves the product setting very long. MTA from Angelus allows the realization of restorative treatment in the same clinical session as the insertion of MTA.
CAN I FILL THE CHANNEL WITH MTA?
The MTA does not have adequate consistency (flow) for filling root canals. Also, after its prey, its remission would be extremely difficult, in case there was a need for retreatment.
