Filling therapy

What are fillings and when are they used?

Fillings describe a material for the restoration of a cavity = a hole in the tooth. In the past, amalgam was mainly used, but due to its harmful properties, it is no longer used in the practice of Dr. Johanna Leonhard.

We use composites. The term comes from the word compositus – put together. These are not plastics in the classical sense, but consist of 80% tiny ceramic, glass and quartz particles, while the actual plastic content is only about 20%.

What do these composites promise?

A lifelike esthetics. Not only posterior teeth look naturally beautiful again with the composites, but also fractured or destroyed anterior teeth can be reconstructed with this material.

We can adjust the color and shape so that the tooth is restored to its original optical condition. In addition, this material ensures particular stability. Composite is characterized by a particularly high abrasion resistance, which means that the material shows particularly low wear over time. The innovative nanocluster technology produces an overall smoother surface during wear and ensures long-term gloss retention.

How do composite fillings last?

Filling is actually no longer the correct term for these high-performance nanocomposites.

No additional ablation of the tooth is required to create a retentive shape.

Composite no longer holds via classic macromechanical retention but via a dentin-adhesive bond. It requires special conditioning and drying of the tooth.

When is composite no longer sufficient?

Composite also allows for restorations of larger defects, as the material is very stable.

However, if a very large area needs to be replaced, or if it is a particularly functionally important or heavily loaded area, it may be necessary to restore the tooth with a partial crown or crown.

How long "does" composite last?

High-quality composites withstand very high mechanical loads and are characterized by high abrasion resistance. With optimal use and good home care, a composite filling can achieve a durability similar to that of an inlay. This corresponds to an average of 10 to 15 years or more.

However, a recurrence of marginal caries, or fracture due to mechanical overload, may necessitate premature replacement.
