Maintaining a healthy, beautiful smile and proper chewing ability is important for everyone. Damaged teeth can cause significant issues, making people self-conscious about speaking and smiling, and making chewing difficult.

To address these problems, dentists use a variety of modern techniques, innovative technologies, and advanced methods for prevention, diagnosis, treatment, and restoration of teeth.

Today, direct and indirect restorations are widely used to restore the anatomical shape of damaged teeth.

But what are these methods, and how do they differ?

This clinical case demonstrates how to restore the chewing function of teeth using the direct method with composite materials and the indirect method with ceramics.

After removing the old filling, it was decided to restore the 46th tooth with an indirect restoration because the destruction of the tooth exceeded 2/3 of the crown. Ceramic onlays were chosen to fully recreate the anatomical shape and restore the functional rigidity of the tooth.

Conclusions

Recently, a variety of dental restoration methods, differing in technology, have become highly relevant in dentistry. The choice of methods for restoring the chewing surfaces of teeth depends on the situation and the volume of natural tissue available. However, the primary goal of a dentist is to achieve a successful and long-lasting result.
