基于牵张成骨骨增量的种植前外科探讨

Discussion on Pre-implantation Surgery Based on Distraction Osteogenesis Bone Augmentation

颌骨骨量不足一直是制约口腔种植学发展的"瓶颈",如何在种植术前或术中同期获得稳定可靠的种植基骨也是学者们研究的焦点之一。随着研究深入,引导骨再生(guided bone regeneration,GBR)、块状骨游离移植、牵张成骨(distraction osteogenesis,DO)、上颌窦提升等骨增量技术得到越来越广泛地应用,但是单一术式的优缺点也充分显现出来。本文将讨论以牵张成骨技术为主体的种植前外科手术。

The shortage of jaw bone is always the bottleneck that restricts the development of dental implantology.How to obtain stable and reliable implant base bone simultaneously before or during the implant surgery is also one of the focal points of the scholars.With the development of the research,a series of bone augmentation technics,such as guided bone regeneration,free bone graft,distraction osteogenesis,and maxillary sinus elevation,are more and more widely used.But the advantages and disadvantages of a single approach are also evident.Pre-implantation surgery with distraction osteogenesis as the main part will be discussed in this paper.
