Dentalresiner

Dentalresiner refers to a category of light-curable resin materials used in dentistry to fabricate and restore dental structures. They are typically based on acrylate or methacrylate monomers and include oligomers, photoinitiators, stabilizers, pigments, and additives. Formulations are available as liquids, pastes, or as pre-shaped CAD/CAM blocks and 3D-printable resins, enabling direct placement, indirect fabrication, or computer-assisted manufacturing.

Curing is achieved with visible blue light or UV light, using dental curing units or projectors. Proper polymerization reduces residual monomer content and enhances mechanical properties. Some products require post-curing to reach full strength and color stability. Handling protocols emphasize protecting against oxygen inhibition and ensuring adequate curing distance and time.

Applications include resin-based direct and indirect restorations, temporary crowns and bridges, denture bases, orthodontic appliances and aligners, surgical guides, occlusal splints, and 3D-printed models and components. The esthetic properties—translucency, color matching, and surface finish—are important for anterior restorations and reversible appliances.

Key properties include esthetics, translucency, color stability, and radiopacity for imaging. They offer good bonding to tooth structure when used with appropriate adhesives. Limitations include polymerization shrinkage, wear resistance concerns under heavy masticatory loads, and potential degradation from thermal and chemical stress over time. Biocompatibility is evaluated per regulatory standards; uncured monomer can irritate tissues if not fully polymerized.

Regulatory status varies by region; dental resins intended for intraoral use must meet safety and effectiveness standards set by authorities such as the FDA in the United States and CE marking in the European Union, along with ISO biocompatibility testing and quality management requirements.
