严重牙周病导致的上颌后牙缺失常伴有严重的牙槽嵴低平。因此,缺少足够的骨高度通常是在这个区域做牙种植的主要困难。1985年Boyne与James首先提出经上颌窦侧壁开窗的上颌窦底提升术,以提升足够的骨高度来进行上颌后牙种植修复。1998年,Summers提出了另外一种窦底提升方法,即从上颌牙槽嵴顶垂直向牙根方向,对上颌窦进行窦底提升,称为垂直提升技术或者牙槽嵴入路上颌窦提升术。本文将结合相关文献及我们的临床经验,叙述这两种手术方式的特点、适应证与禁忌证、临床步骤以及可能的并发症和处理方法。希望对读者理解上颌窦提升术有所帮助。
Serious periodontal disease caused by the absence of maxillary posterior teeth often accompanied by severe alveolar crest flat. Therefore, the lack of adequate bone height is often the major difficulty in performing dental implants in this area. In 1985 Boyne and James first proposed maxillary sinus floor elevation through the maxillary sinus window in order to enhance the bone height for maxillary posterior implant. In 1998, Summers proposed another sinus floor lifting method, which is to lift the maxillary sinus sinus vertically from the maxillary alveolar ridge to the root, which is called vertical lifting technique or alveolar approach maxillary sinus lift. This article will combine the relevant literature and our clinical experience, describes the characteristics of these two surgical methods, indications and contraindications, clinical procedures and possible complications and treatment methods. I hope readers understand the maxillary sinus lift helpful.
