A 24-year-old female with a medical history significant for epilepsy had a traumatic fall and fractured the buccal plate in the maxillary anterior region. Mobility of class III on nos. 8, 9, and 10 ensued.

The patient went to the emergency room where nos. 7–10 were splinted for temporary stabilization. A CBCT scan revealed complete loss of buccal bone around the region of nos. 8, 9, and 10. A clinical exam showed loss of soft tissue, tooth size and space discrepancy, supernumerary teeth, and gingival zenith asymmetry. Teeth nos. 8, 9, and 10 were deemed hopeless and implant therapy was treatment planned. With the volume of hard- and soft-tissue loss, implant placement involved multiple hard- and soft-tissue augmentation procedures. The final results six years post final restoration are shown here, demonstrating good stability.
