Introduction

: Alveolar bone deficiency is a common post-extraction sequela that adversely affects implant placement. Therefore, ridge augmentation is often required to obtain proper bone quantity and quality for restoratively driven implant placement. This case series describes the successful horizontal and vertical alveolar ridge augmentation using custom fabricated allogenic block bone grafts.

Case Presentation

: Two healthy partially edentulous patients presented to private practice seeking dental implant treatment. Initial clinical examination and CBCT (cone beam computed tomography) radiographic analysis showed moderate to large horizontal ridge defects. Treatment options were discussed for alveolar ridge augmentation and the patients elected to undergo the custom allogenic block graft procedure to regenerate the atrophied alveolar ridges. The CBCT scan in conjunction with computer-aided design/computer-aided manufacturing (CAD/CAM) technology were used to fabricate customized allogenic block grafts based on alveolar ridge topography. The custom allogenic block graft allowed less surgical time and decreased post-operative morbidity. The grafted area was allowed six months of healing time. Follow-up radiographs showed the stability of the graft followed by dental implant placement. The dental implants were functionally loaded, and successful implant esthetics and function achieved.

Conclusion

: Custom allogenic block grafts could provide a promising innovative method for optimal ridge augmentation.
