这项系统评价的目的是评估在种植牙之前完全无牙的萎缩性上颌骨中与不同植骨技术相关的体积变化。根据PRISMA指南进行搜索。形成了一个PICO问题,和PubMed,Scopus,Embase,搜索了Cochrane图书馆的数据库,涵盖2000-2018年期间。从研究人群的结果中提取相关数据,手术细节,关于体积数据获取的技术信息,植入前的骨增强程序和体积结果。包括六篇文章,其中84名患者的合并人群。所有患者上颌骨完全无牙,其水平宽度<3-4mm或垂直高度<6-7mm。最常使用the骨和上升支作为移植物。六项研究中有五项报告了窦嵌体移植物(SIG)的体积,四项报告了外侧骨增强(LBA)的体积。增强区域的射线照相分析在研究中有所不同。SIG骨增强手术后的体积损失为5%至50%,LBA为5%至47%。无牙上颌骨的所有手术增强技术都容易吸收;似乎没有更好的手术,但是有一些有趣的观察。
The aim of this systematic
review was to evaluate the volumetric changes associated with different bone grafting techniques in the completely edentulous atrophic maxilla before dental implant placement. A search was performed according to the PRISMA guidelines. A PICO question was formed, and the PubMed, Scopus, Embase, and Cochrane Library databases were searched, covering the period 2000-2018. Relevant data were extracted from the results regarding study population, surgical details, technical information on volumetric data acquirement, and volumetric outcome after bone augmentation procedures before implant placement. Six articles with a combined population of 84 patients were included. All patients had a completely edentulous maxilla, with a crestal horizontal width of <3-4mm or a crestal vertical height of <6-7mm. The iliac bone and ascending ramus were most frequently used as grafts. Five of the six studies reported volumes of sinus inlay graft (SIG) and four reported volumes of lateral bone augmentation (LBA). Radiographic analyses of the augmented areas differed among the studies. Volume loss after bone augmentation procedures ranged from 5% to 50% for SIG and from 5% to 47% for LBA. All surgical augmentation techniques for the edentulous maxilla are prone to resorption; no procedure seemed to be superior, but some interesting observations were made.
