愈合后与新鲜的拔牙窝
Key points
- 在愈合后与新鲜的拔牙窝植入的种植体的短期存活率看起来相似
- 这一主题的长期数据很有限
介绍
缺齿牙颌的治疗可能需要在愈合后和新鲜的拔牙窝植入种植体。种植体周围不相同的硬组织和软组织水平(图 1 和 2),尤其是在颌孔间区域,可以通过将骨校平到同一水平来进行调整。
在短期随访研究中,在新鲜拔牙窝与在愈合后拔牙窝中植入种植体之间未发现差异。近期文献表明,即刻植入种植体与即刻负重相结合也未降低种植体的存活率。
在新鲜拔牙窝中即刻植入种植体不能防止牙槽嵴萎缩。但即刻植入种植体的优点是可在一定程度上保持种植体周围的软组织(图 3)。2 年后,在新鲜拔牙窝与愈合后拔牙窝植入的种植体的种植体周围骨萎缩率相似。
愈合后拔牙窝中的种植体
优点:
- 解决可能的感染
- 骨质缺损的愈合
- 因拔牙窝软组织愈合而形成更多的软组织量
缺点:
- 牙槽嵴持续萎缩导致渐进性骨量减少
- 延长了治疗时间
新鲜拔牙窝中的种植体
优点:
- 总治疗时间缩短
- 患者不适减轻
缺点:
- 初期稳定性可能受损
- 颊侧/舌侧部位种植体上的角质化粘膜量可能受损
