Allograft Customized Bone Block in the Edentulous Maxilla: A 6-Month CBCT Analysis and 15-Month Follow-up

Maxillary atrophy is relatively common among long-term edentulous patients, especially in older adults. Severe forms, although less prevalent, are still frequently encountered in implant and prosthodontic practice, particularly in patients who have been without teeth for many years or who have worn poorly fitting dentures. This case report presents the treatment of a 77-year-old female smoker who had been missing her teeth for 22 years and had a non-functional prosthesis. The article describes the vertical and horizontal gain in the patient's edentulous maxilla utilizing allograft customized bone blocks to extensively augment the amount of bone. Upon review of a CBCT scan taken after 6 months, the bone gain was evident, revealing a ridge width of between 6.9 mm and 8.9 mm and confirming that the outcome matched the design of the allograft customized bone block. The allograft customized bone block treatment showed itself to be a potential alternative to extensive bone harvesting procedures for treating and augmenting a severely atrophic maxilla while yielding decreased donor site complications and postoperative issues.
