Replacement of fractured maxillary central incisor
Initial crown preparation was extended to the bone level, violating the biologic width and creating adverse biologic response. Crown was removed and tooth prepared for new crown. Inspection of tooth did not reveal that tooth was cracked. Initial good mucosal response was not sustained and became progressively worse. Periodontist reflected the flap and crack was detected. Tooth was extracted and implant placed. Mucosal recession was experienced due to bone loss associated with cracked root.
