OPUS BULK FILL APS A1 (4g syringe) is a premium, light-curing composite resin by FGM Dental Group. Designed for high-efficiency posterior restorations, it features proprietary Advanced Polymerization System (APS) technology to minimize shrinkage stress and dramatically streamline clinical chair time.
Key Clinical Advantages
Single-Fill Agility: Allows for incremental layering up to 5mm deep, eliminating the need for complex, multi-layer buildups in Class I and Class II posterior cavities.
Low Shrinkage Stress: APS technology provides exceptional polymerization efficiency and significantly reduces microleakage and post-operative sensitivity.
High Mechanical Strength: Contains approximately 79% mass fillers, ensuring superior wear resistance and durability under occlusal loads.
Extended Working Time: Provides a generous working window under ambient operatory lighting, making sculpting and anatomical shaping much easier.
Aesthetic Predictability: Features smart opacity—the material is translucent enough for a thorough 5 mm light cure, but becomes more opaque and natural-looking post-polymerization with minimal color shift.
