Composite resins are widely used materials in Dentistry to restore teeth that have suffered damage or cavities. They are known for their great versatility and aesthetics, since they can be matched to the color of natural teeth.
There are several categories of composite resins available on the market, each with its own characteristics and indications. Some of the most common categories include:
- Low-viscosity composite resins: They are indicated for filling small cavities and dental fissures, as well as for repairing old restorations. They have a fluid texture, which facilitates application.
- High-viscosity composite resins: They are thicker than low-viscosity resins, which makes them more suitable for filling larger cavities. They are often used to restore posterior teeth, which withstand more pressure during chewing.
- Bulk fill composite resins: These resins were developed to be applied in thicker layers, allowing the dentist to restore a tooth more quickly. They also have a lower polymerization shrinkage, which helps to prevent the restoration from detaching over time.
- Nanoparticulate composite resins: These resins are made with very small particles, which gives them greater strength and durability. They are often used to restore posterior teeth, which undergo more pressure during chewing.
- Resin cement composite resins: These resins are used to cement crowns and dental bridges. They have a stronger and more durable bond than conventional cements.
It is important to emphasize that the choice of the most suitable composite resin for each case depends on several factors, such as the location and size of the cavity, the patient’s chewing force and the desired aesthetics. Therefore, it is essential to have the guidance of a dentist specialized in choosing the most suitable material.
In summary, composite resins are extremely useful and versatile materials in Dentistry, allowing for aesthetic and long-lasting restorations. The choice of the most suitable composite resin category for each case will depend on the specific needs and conditions of each patient.
