Base-liner material TheraBase BISCO
TheraBase BISCO base-liner is a lining material placed beneath composite restorations, eliminating the need for any other liners such as glass ionomer or calcium hydroxide.
Features of TheraBase BISCO Base-Liner Material:
One of the best base-liners and the fourth member of the Thera family
Self-adhesive – the bond between TheraBase and dentin does not interfere with the release of calcium and fluoride
Dual-cure – ensuring complete polymerization without concern
Alkaline pH to help maintain tooth health
Radiopaque
Self-etch – prevents postoperative sensitivity
Easy to use
Simultaneous and continuous release of calcium and fluoride
High flexural and compressive strength
Contains MDP monomer for excellent adhesion
Comparison of TheraBase with Glass Ionomer:
Glass ionomers release only calcium, while TheraBase releases both calcium and fluoride
TheraBase is much easier to use than glass ionomers — no need to worry about powder or liquid ratios
Glass ionomers have relatively low compressive strength
Comparison of TheraBase with Calcium Hydroxide:
TheraBase releases significantly more calcium and fluoride than calcium hydroxide liners
Radiopacity of calcium hydroxide liners is much lower than that of TheraBase
TheraBase has much higher compressive strength than calcium hydroxide liners
Comparison of TheraBase with Flowable Composite:
Flowable composites do not release calcium or fluoride
Flowable composites require an adhesive, increasing both procedure time and cost
Flowable composites are light-cure only and may not fully polymerize, leading to possible sensitivity
TheraBase is dual-cure — it cures within 20 seconds with light, or fully self-cures within 4 minutes even without light
