Root canal retreatment with a fractured instrument and zirconia crown

$Root canal retreatment with a fractured instrument and zirconia crown$

Complaints:

Tooth pain after previous endodontic treatment performed at another clinic.

Diagnosis:

Apical periodontitis of tooth 4.6.

Treatment:

Following comprehensive diagnostics (CT scan and periapical X-ray), root canal retreatment was performed under STA computer-assisted local anesthesia. Using a Leica M320 operating microscope, the fractured instrument was bypassed with the ByPass technique, followed by mechanical and chemical preparation of the canals and three-dimensional obturation with warm gutta-percha. The tooth was restored with Estelite Asteria composite and the treatment was completed with a full-contour zirconia crown fabricated using CAD/CAM technology.
