本研究的目的是回顾性评价Astra Tech种植体在上颌磨牙区进行上颌窦提升和骨移植的临床存活率。从2009年9月至2012年2月，选择了99个Astra Tech种植体（Osseospeed），使用上颌窦提升术植入上颌磨牙区域，至少随访1年。对种植体种植体的种植体高度、上颌窦入路技术、种植体材料及种植体成活率进行评价。在99个种植体中，存活率为90.9%; 8个种植体在种植体放置后1年内失效，1个种植体在种植体加载后1年失效。所有失败的种植体均在上颌窦提升的同时放置。种植体植入前牙槽骨平均高度为6.9 mm，而失败种植体的牙槽骨平均高度为2.1 mm。Astra Tech种植体放置在上颌磨牙区通常具有良好的存活率，但种植前牙槽骨高度降低与种植体失败之间的关系需要进一步关注。
The aim of this study was to retrospectively evaluate the clinical survival rate of Astra Tech implants in the maxillary molar region performed with sinus lift and bone graft. Ninety-nine Astra Tech implants (Osseospeed) placed in the maxillary molar region using sinus lift from September 2009 to February 2012 were selected with a minimum follow-up period of 1 year. The height of alveolar bone, sinus approach technique, bone material and implant survival rate were evaluated. Of the 99 implants, the survival rate was 90.9%; 8 implants failed within 1 year after implant placement, and 1 implant failed 1 year after implant loading. All failed implants were placed with sinus lift simultaneously. The average height of alveolar bone before implant placement was 6.9 mm, while the height of alveolar bone of failed implants was 2.1 mm, on average. Astra Tech implants placed in the maxillary molar region had generally good survival rates, but the relationship between reduced pre-implant alveolar bone height and implant failure requires further attention.
