Curiosity as to what is used to form that tooth-coloured stuff that your dentist moulds around a broken edge or cracks into cavities is not an uncommon thing. Composite bonding is a staple in the contemporary dentistry, yet its mechanics is a combination of delicate chemistry and an art.
Materials that Comprise Dental Composite Bonding –
1. Resin Matrix (Bis-GMA, UDMA and Friends)
All composite bonding materials begin with a foundation of synthetics resins. This mix is typically anchored by Bis-GMA (bisphenol A-glycidyl methacrylate) although the cast members assisting in formation of a viable, long lasting texture that can be molded by dentists include UDMA, TEGDMA and HDDMA. Imagine that this is the stretchable canvas onto which your smile is painted.
2. Filler Particles (Silica and Glass Powders)
Resins would just not stick long on a biting surface! And here fine fillers, like silica (crystalline, silicon dioxide), lithium or barium glass, and even zirconia, come in. These are strong, shiny, durable and simulate the gleam and the hardness of natural enamel. Gone, we should have a putty tooth instead of a composite.
3. Photoinitiators (Camphorquinone, PPD, Lucirin)
These small molecules are responsive to blue-curing lights and initiate the accelerated hardening process which fixes your bonded tooth within minutes. The most common one is camphorquinone- the one that makes the magic when one is in the doctor of dentist chair.
4. Silane Coupling Agents
As molecular glue, such materials as silane make sure that the fillers and resin mix does not separate. This increases strength in addition to the proximity with which the composite embraces your natural tooth.
5. Additives & Pigments
Labs use UV stabilizers, different pigments and even fluoride releasing agents to stabilize shade, resist stains and give the tooth colour a more realistic look. These render the modern composite bonding almost invisible on the skillful application and other extra durable in the day-to-day usage.
