TheraBase™ is a dual-cure, calcium and fluoride releasing, self-adhesive base/liner. Utilizing the THERA technology, TheraBase chemically bonds to tooth structure, and releases and recharges calcium and fluoride ions.1 TheraBase’s calcium release generates an alkaline pH which promotes pulp vitality.2 It is a dual-cured material that will polymerize even in deep restorations where light cannot reach.
TheraBase is stronger and more durable than other base materials, glass ionomers and resin-modified glass ionomers.* Additionally, it is radiopaque allowing for easy identification on radiographs, providing a quick and effective diagnosis.
One 8g syringe of TheraBase provides approximately 27 – 29 base applications. Simply dispense TheraBase, and either light cure for 20 seconds or allow to self-cure. Proceed with finishing the restoration.
TheraBase has the strength, durability, and THERA technology to provide the best foundation for each restoration.
Base and Liner. The THERA way.
Releases and recharges Calcium and Fluoride
Continuous Calcium and Fluoride ions release.1
No bonding agent required.
High Flexural Strength
Stronger and more fracture resistant.
High Compressive Strength
Absorbs shock and stress from occlusal forces without fracturing.
Material will fully cure even in deep restorations where light cannot reach.
Contains the adhesion promoting monomer MDP, ensuring a reliable and optimal bond to dentin.3
THERA Hydrophilic Matrix
BISCO has developed a hydrophilic matrix that allows for ion exchange. Previous or traditional resin matrices have been hydrophobic, but BISCO’s matrix allows for ion exchange as water goes into the matrix, reacts, and calcium hydroxide ions and fluoride ions are released. At the calcium-rich interface between TheraBase and the dentin, an alkaline pH environment is created.
Strong and Lasting Protection
TheraBase has higher flexural & compressive strength than similar base materials, GI’s and RMGI’s, making it more durable and less prone to fracture.*
Optimum Calcium & Fluoride Release
In deep restorations and when pulp exposure occurs, BISCO recommends the use of TheraCal LC for direct and indirect pulp capping and as a liner. Both TheraBase and TheraCal LC can be used together in a sandwich technique case scenario for optimum calcium and fluoride release benefits and ultimate pulp protection.
Yes. TheraBase is not intended to replace TheraCal LC. TheraBase is a material to be used as a base/liner under restorations while TheraCal LC is indicated for direct and indirect pulp capping and as a liner. They may both be used together in a sandwich technique case for optimum calcium and fluoride release benefits.
TheraBase is a dual-cured, calcium and fluoride releasing material indicated for base restorations. TheraCal LC may also be used as a base but needs to be placed in 1 mm increments and light cured between layers. TheraBase and TheraCal LC both utilize THERA technology, a hydrophilic resin matrix that facilitates calcium release. TheraBase and TheraCal LC are both radiopaque and generate an alkaline pH.
Bases are typically a thicker placement of material. TheraBase is dual-cured ensuring that your restorations will polymerize even in deep restorations where light cannot reach.
Bonding is not required before the placement of TheraBase. TheraBase is a self-adhesive material and the benefits of the calcium and fluoride release are hindered if a bonding agent is placed between TheraBase and the dentin.
Approximately between 27-29 base applications.
TheraBase should be stored at room temperature (68°-77° F; 20°-25° C).
TheraBase continuously releases both fluoride and calcium1, but GI’s and RMGI’s release only fluoride. TheraBase is offered in an auto-mix dual syringe providing consistent mix and immediate delivery. GI’s and RMGI’s, typically require manual mixing, trituration, or a special dispenser. TheraBase has higher flexural & compressive strength than leading GI’s and RMGI’s, making it more durable and less prone to fractures*.
Working Time: Minimum 1 minute (includes mixing) at 22°C (71.6°F).
Setting Time: Maximum 5 minutes at 37°C (98.6°F).
