The purpose of this study is to analyze 1- and 3-year clinical performances of narrow diameter implants (NDIs) versus regular diameter implants (RDIs). A search of electronic databases and a manual search was performed for the time period January 2000 to April 2018. A meta-regression was used to evaluate the effects of the "fixed effects" model on the implant survival rates, prosthesis success rates and marginal bone loss (MBL) with follow-up time of 1 year and 3 years. Of the 11 studies included, the overall combined 1-year implant survival rates were 98.14% for NDIs and 98.20% for RDIs. The overall combined 3-year implant survival rates were 98.71% for NDIs and 98.84% for RDIs. The corresponding values for 1-year prosthesis success rates were 96.94% for NDIs and 99.25% for RDIs. The corresponding values for 3-year prosthesis success rates were 89.25% for NDIs and 96.55% for RDIs. The meta-regression showed no significant differences between NDIs and RDIs regarding implant survival rates, prosthesis success rates, and MBL in 1-year and 3-year follow-up ( > .05). The results of this meta-analysis concluded that the implant diameter did not affect its survival rates, prosthesis success rates, and MBL in 1 and 3 years. The use of NDIs instead of bone augmentation procedures with RDIs did not affect its survival rates, prosthesis success rates, and MBL in the short-term and middle-term. However, more high-quality randomized controlled trials and long follow-up studies are needed on this topic.
本研究旨在分析窄直径种植体（NDIs）与常规直径种植体（RDIs）1年和3年的临床性能。对2000年1月至2018年4月期间的电子数据库进行了检索，并进行了人工检索。采用meta回归分析“固定效应”模型对随访1年和3年时种植体生存率、修复体成功率和边缘骨吸收（MBL）的影响。在纳入的11项研究中，NDIs的1年总体联合种植体生存率为98.14%，RDIs为98.20%。NDIs的3年总体联合种植体生存率为98.71%，RDIs为98.84%。1年修复体成功率的相应值，NDIs为96.94%，RDIs为99.25%。3年修复体成功率的相应值，NDIs为89.25%，RDIs为96.55%。meta回归分析显示，在1年和3年随访中，NDIs和RDIs在种植体生存率、修复体成功率和MBL方面无显著差异（P>0.05）。该meta分析结果得出结论，种植体直径在1年和3年时不影响其生存率、修复体成功率和MBL。在短期和中期，使用NDIs而非采用RDIs的骨增量手术不影响其生存率、修复体成功率和MBL。然而，关于该主题还需要更多高质量的随机对照试验和长期随访研究。
