Root canal retreatment with anatomical restoration using a zirconia crown

Root canal retreatment with anatomical restoration using a zirconia crown

Complaints:

Discomfort and pain while chewing in the area of tooth 1.4.

Diagnosis:

Apical periodontitis of tooth 1.4.

Treatment:

Treatment was performed under STA computer-assisted anesthesia with rubber dam isolation. After removing the old filling, root canal retreatment was carried out, and under the control of a Leica M320 dental microscope, the canals were mechanically and chemically prepared to their physiological apices using NiC and SOCO instruments. Ultrasonic-activated irrigation with sodium hypochlorite and citric acid solutions was used to ensure thorough cleaning of the root canal system. Following hermetic obturation using the warm gutta-percha 3D technique, the tooth was restored with Estelite Asteria composite material and prepared for prosthetic restoration. The final stage included fabrication and placement of a full-anatomical zirconia crown using CAD/CAM technology, restoring the tooth’s natural anatomy and function.

In this clinical case, the patient presented with discomfort and pain while chewing in the area of tooth 1.4.

After a CBCT scan of the jaws, apical periodontitis of tooth 1.4 was diagnosed.

Treatment was performed under STA computer-assisted anesthesia using a rubber dam and a Leica M320 operating microscope. Root canal retreatment, cleaning, and hermetic sealing were completed using the warm gutta-percha 3D obturation technique.

Following the endodontic stage, the tooth was restored with Estelite Asteria composite material and fitted with a full-anatomical zirconia crown fabricated using CAD/CAM technology.

Result:

The source of infection was eliminated, pain was resolved, and the tooth’s function was fully restored.
