Bone quality and quantity are important factors with regard to the survival rate of dental implants. The aim of this study was to conduct a systematic review of dental implants inserted in low-density bone and to determine the survival rate of dental implants with surface treatments over time. A systematic review of the literature was undertaken by two independent individuals; the Medline/PubMed database was searched for the period July 1975 to March 2013. Relevant reports on bone quality and osseointegration of dental implants were selected. The search retrieved 1018 references, and after inclusion and exclusion criteria were applied, 19 studies were selected for review. A total of 3937 patients, who had received a total of 12,465 dental implants, were analyzed. The survival rates of dental implants according to the bone density were: type I, 97.6%; type II, 96.2%; type III, 96.5%; and type IV, 88.8%. The survival rate of treated surface implants inserted in low-density bone was higher (97.1%) than that of machined surface implants (91.6%). Surface-treated dental implants inserted in low-density bone have a high survival rate and may be indicated for oral rehabilitation. However, more randomized studies are required to better evaluate this issue.
骨质量和骨量是影响牙种植体存活率的重要因素。本研究旨在对植入低密度骨的牙种植体进行系统评价，并确定经过表面处理的牙种植体随时间推移的存活率。由两名独立人员对文献进行系统评价；检索了1975年7月至2013年3月期间的Medline/PubMed数据库。选择了关于牙种植体骨质量和骨整合的相关报告。检索到1018篇参考文献，应用纳入和排除标准后，选择了19项研究进行综述。共分析了3937例患者，他们总共接受了12465颗牙种植体。根据骨密度，牙种植体的存活率分别为：I型，97.6%；II型，96.2%；III型，96.5%；IV型，88.8%。植入低密度骨的经过处理表面的种植体的存活率（97.1%）高于机械加工表面种植体（91.6%）。植入低密度骨的经过表面处理的牙种植体具有较高的存活率，可用于口腔修复。然而，需要更多的随机研究来更好地评估这个问题。
