OT BF Bulk Fill Composite is a next-generation light-cured, radiopaque restorative material made for Class I and II cavities. Thanks to its exceptional translucency and ultra-low polymerization shrinkage (just 1.49%), it can be placed in layers up to 4.5 mm with minimal stress. Easy to shape and perfectly adaptable, it flows into every detail of the cavity while resisting stickiness to dental instruments.
Designed for efficiency and durability, it ensures predictable outcomes for both clinicians and patients—making it the go-to solution for faster, stronger posterior restorations.
 
✅ Key Benefits

High Depth of Cure
Ensures full polymerization even in deeper cavities.
Superior Mechanical Properties
High compressive and flexural strength for long-lasting posterior restorations.
Excellent Wear Resistance
Withstands heavy occlusal loads and daily function.
Good Handling & Sculptability
Non-sticky, easy adaptation to cavity walls, and smooth contouring.
Esthetic Results
Natural translucency and shade matching with enamel and dentin.
Radiopaque
Clear radiographic visibility for follow-up assessments.
Versatile Applications
Suitable for Class I & II posterior restorations, base layers, and core build-ups.
