case_images: Saudi female patient had undergone root canal retreatment and temporary crown placement on the maxillary right central incisor (#11; FDI tooth notation system) by a restorative dentist in 2015. She originally came to replace her preexisting upper anterior crowns due to greyish discoloration and cosmetic concerns (Figure 1).

case_images: Excess luting cement from previous procedures on the tooth's buccal surface was removed, and the surface was smoothed using a flame-shaped finishing bur to contour the Geristore  cement, ensuring a smooth root surface.  Figure 4 illustrates the key steps involved in the surgical repair of tooth #11.
