上颌窦提升到底是什么

上颌窦提升,是把您上颌窦的底抬高,并在它下面填入植骨材料,好让上颌后牙区有足够结实的骨去锚定一枚种植体。一句话就是全部意思。上颌窦是气腔,正好坐落在您上颌磨牙和前磨牙的牙根上方;当您失去这些牙时,会发生两件事:托着它们的骨会萎缩,而上方的窦腔会悄悄向下扩展进那片空出来的地方。放着不管,您可能只剩几毫米的骨,而种植体需要的比这多。

所以这项手术并不是关于您的呼吸,也不是医学意义上关于您的鼻窦——没有人在动您怎么闻气味或者鼻子怎么引流。医生处理的是窦腔最底部那层薄薄的骨板,把衬在它上面的黏膜掀起来,在下面造出新骨。它是种植牙科里被研究得最多、也最可预期的手术之一,几十年来都是常规操作。对许多患者来说,它就是「您骨头不够」和拿到一颗能用很久的固定牙之间的那道分界。

先说一句实话:上颌窦提升只用于上颌,而且通常只用于上颌的后段。如果有人告诉您需要做,那是因为影像显示您窦下的骨太矮,今天还托不住一枚稳固的种植体。这并不意味着您的鼻窦有什么毛病。

手术过程,一步一步来

一切都在动钻之前就开始了——从影像开始。一次三维锥形束CT会测绘出您剩余骨的确切高度、窦黏膜的形态与厚度,以及窦底的位置。正是它告诉医生您这个病例需要两种入路中的哪一种,以及种植体能不能当天放进去,还是需要等。在我们中心,那次影像是免费的,而且由真正会做您这台手术的医生亲自阅读,所以关于您的上颌窦,不会有任何事情在手术中途才变成意外。

主要有两种技术,用哪一种取决于您已经有多少骨。牙槽嵴顶入路(或称骨凿入路)是更轻的那一种:当您大约有 5 到 6 毫米或更多的骨时,医生就顺着为种植体预备的同一个通道往上做,把窦底向上顶起几毫米并加入植骨材料——常常在同一次就诊里就把种植体放进去。侧壁开窗入路用于更大幅度的提升:当骨很薄时,医生在颌骨侧壁开一个小窗,小心地把黏膜剥离开,再用植骨材料填满下面的空间。这是更大的手术,种植体常常要等新骨成熟之后再放。

在就诊当天,您会用局部麻醉麻好,如果您更愿意睡过去,也可以用静脉镇静。医生会用刻意放慢的手法把黏膜掀起来——那层黏膜就是整场比赛的关键,保护住它,是干净的结果与一次并发症之间的分水岭。植骨材料放进去,位点用几针缝合关闭,就结束了。大多数患者告诉我们,感觉比拔一颗牙还轻。当您的骨厚到足以让种植体在植入时就稳稳坐住时,我们会在一次就诊里把上颌窦提升和种植体一起完成,您可以在我们的上颌窦提升加即刻种植页面上读到更多。

怎样为上颌窦提升做准备

您能给自己帮的最大的忙,是在那天到来之前,把您健康状况的准确画面交给医生。带上一份完整的用药和补充剂清单——尤其是抗凝药,以及任何和心脏、糖尿病或免疫系统有关的药物,它们都会改变一个病例的规划方式。提一提任何鼻窦感染、过敏或鼻部手术史,因为发炎或感染的鼻窦应该在提升之前先平息下来,而不是在手术当中。如果您吸烟,这就是要坦白谈的那件事:吸烟会明显拖慢骨的愈合,而在术前术后减少吸烟,确实会改善植骨的成活情况。

后勤比人们以为的更重要。如果您要用静脉镇静,就需要有人送您回家,而且术前几小时不能进食——您的团队会给您确切的时间。提前把处方药取好,免得麻着嘴还在找药房。在家里备好软的、凉的食物:酸奶、奶昔、鸡蛋、不烫嘴的汤。并且给术后安排一两天真正低强度的日子。这不是一项能靠一场接一场的会议硬撑过去的手术。

最后,在坐上椅子之前先把问题问清楚。问一问您这个病例是一次完成(提升加种植)还是分阶段的方案,对您来说愈合大概要多久,以及总数是多少——我们的种植牙费用页面拆解了什么在推动这个数字,而通过 Cherry、CareCredit 等的分期把它摊开。如果您想在做决定之前把一切都摸清楚,咨询和三维影像都是免费的,您离开时会拿到写下来的方案。您可以在这里预约那次就诊

恢复,以及之后的几周

最初 48 小时是要认真对待的。预期面颊和上唇一带会有一些肿胀和轻度酸痛——冷敷和外科医生给您开的药能应付大部分。压过其他所有条的那一条规则有点反直觉:不要用力擤鼻涕,打喷嚏时能张着嘴就张着嘴。刚被掀起来的那层黏膜,在安定下来的时候需要的是平静,而用力擤鼻涕,正是它在这一两周里最不想要的那种压力。同样的道理,几天之内避开吸管、提重物和剧烈运动。

接着是更需要耐心而不是力气的那一段:植骨材料必须变成您自己活的骨。当提升与种植分阶段进行时,这段愈合在放入种植体之前通常要走大约四到九个月,而您的外科医生会用影像确认它已经就绪——不是靠猜。当骨条件允许种植体当天就放进去时,它会在差不多的时间窗里与植骨一起整合。无论哪一种,您都会由做这台手术的同一批医生来复诊。我们详细的术后须知把每天该做什么走了一遍,而如果有什么不对劲,您打给的是外科医生,不是一个呼叫中心。

还有疑问? 读者接下来常问的问题。

上颌窦提升疼吗?

对多数人来说,不会——患者经常形容它比拔一颗牙还轻松。手术在局部麻醉下进行,如果您更愿意睡过去,也可以用静脉镇静。术后几天可以预期有一些肿胀和轻度酸痛,用冷敷和外科医生给您开的药来处理。这种不适通常时间短,也在意料之中。

上颌窦提升之后多久可以放种植体?

取决于您的骨。当您的骨足以让种植体在植入时就稳稳坐住时,我们常常在同一次就诊里完成提升并放入种植体。当骨太薄、给不出稳定性时,正确的做法是先植骨,等它愈合之后再放种植体——通常是大约四到九个月以后,并用影像确认。您的锥形束CT在安排任何事情之前就作出这个判断,所以您一开始就知道自己走的是哪条路。

上颌窦提升会影响我的呼吸或鼻窦吗?

做得规范的话,不会。医生只处理窦底那层薄骨,不去动您的鼻窦怎么引流、您怎么呼吸、您怎么闻气味。被掀起的黏膜会重新落回植骨材料上方,鼻窦照常工作。如果您有慢性鼻窦问题的病史,请提前说明——活动性感染应该在提升之前治好,而不是在手术当中。

上颌种植是不是一定要做上颌窦提升?

不一定。只有当您窦下的骨太矮、锚不住一枚种植体时才需要,而且只在上颌后牙区。要确切知道,唯一的办法是三维影像。对于骨吸收非常严重、植骨已经不划算的上颌,还有一条多数诊所提供不了的路——锚定在颧骨里的颧骨种植体,它完全绕开了上颌窦这个问题。
