Atrophic edentulous anterior maxilla is a challenging site for implant placement and has been successfully treated surgically by anterior maxillary osteoplasty. This procedure is associated with considerable discomfort, morbidity, and cost-and consequently reduced patient acceptance. The efficacy and safety of minimally invasive bone augmentation of the posterior maxilla has not been extended thus far to the anterior subnasal maxilla. We present 2 representative cases in which minimally invasive subnasal floor elevation was performed along with minimally invasive antral membrane balloon elevation. Both segments underwent bone grafting and implant placement during the same sitting. Minimally invasive anterior maxilla bone augmentation appears to be feasible. Designated instruments for alveolar ridge splitting and nasal mucosa elevation are likely to further enhance this initial favorable experience.
