Key points
- 翼状种植体植入是一种可避免使用窦提升或其他移植手术来治疗上颌后牙区的备选方案
- 翼状种植体尤其适用于部分牙缺失的情况,目的是避免使用远端悬臂
- 植入翼状种植体需要具备外科手术经验
- 翼状种植体的成功率较高,骨缺失水平与传统种植体类似,发生并发症的几率很低,而且患者接受度良好
适应证
由于骨量有限且存在上颌窦,在缺齿上颌中植入种植体可能具有挑战性。翼状种植体提供了一种备选方案,它允许使用残留骨来进行种植体固定,并可克服对增量手术的需求。为了避免使用远端悬臂,在部分牙缺失和全口牙缺失情况下宜植入翼状种植体。根据文献研究结果显示,翼状种植体与翼突上颌种植体没有明显的差异。
临床建议
在科学文献中,“翼状种植体”、“翼突上颌种植体”和“结节种植体”往往互换使用(用于描述位于磨牙后区的种植体)。根据定义,所有“翼状种植体”都会包围结节区域并啮合翼状板,但并非所有“结节种植体”都一定会啮合翼状板(它们位于翼突上颌区域更前部的位置,与窦后壁平行)。
所有这些不同治疗方案的成功率似乎很接近。因此,对于是否需要在翼状板层面啮合种植体,目前仍存有争议。
预后
翼状种植体的平均成功率为 90.7%。不过,目前仍没有足够的数据表明第一年负重以后的种植失败情况,因而导致难以得出关于这些种植体长期成活率的结论。
并发症
在翼状板层面植入种植体可能会引发出血(从翼丛或上颌动脉出血)。然而,通过在结节层面植入种植体可避免此问题。另一种并发症是缺乏初期种植体稳定性 [Candel 2012],此问题可以通过小尺寸钻牙方案和创新种植体设计来解决 (NobelActive)。
