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.
萎缩性无牙上颌前牙区是种植体植入的挑战性部位，以往通过上颌前份骨成形术进行手术治疗取得了成功。该手术会带来相当大的不适、并发症和费用，因此患者接受度降低。迄今为止，后牙区微创骨增量的有效性和安全性尚未扩展至鼻下份上颌前牙区。我们展示2例代表性病例，其中进行了微创鼻底提升术并联合微创上颌窦膜球囊提升术。两个部位均在同一次手术中进行了植骨和种植体植入。微创上颌前份骨增量似乎是可行的。用于牙槽嵴劈开和鼻黏膜提升的专用器械可能会进一步提升这一初步的良好经验。
