Dental implant placement in the anterior maxilla may be limited by the position of the anterior portion of the nasal cavity, particularly when the vertical height of the residual alveolar process is reduced. In such instance, penetration of the inferior border of the nasal cavity may occur. Nasal floor augmentation (NFA) techniques utilising autogenous bone grafts, allografts, xenografts, and combination grafts have been described in the literature [6–9] as methods for managing the atrophic maxilla. Although more clinical research is needed to fully evaluate the predictability of NFA, it may provide a viable and less invasive option than a traditional Le Fort 1 osteotomy [10].
