The purpose of this systematic literature review was to compare the clinical performance between conventionally- (delayed) and immediately-loaded implants. A literature search of studies published between 1995 and 2012 was performed using several electronic databases and the following key words: "immediate loading", "dental implants", "immediate function", "early loading", "oral implants", "immediate restoration", and "systematic review" was performed. The electronic search was supplemented with hand-searching in dental journals and cross-referencing within the selected articles. Studies were considered for inclusion if they analyzed the success of the immediate loading protocol for implants, with emphasis given to randomized, controlled clinical trials. Among the clinical studies extracted from the literature, 120 studies met the inclusion criteria and were included in this systematic review. These studies included trials that involved yielded consistent results of success rates of immediately-loaded implants comparable to those known from conventionally-loaded implants, which were subjected to the immediate loading protocol or other loading protocols. According to the findings, there is evidence to suggest that immediate loading protocols demonstrate high implant survival rates and could be cautiously recommended for certain clinical situations. However, studies with a high level of evidence, especially randomized, controlled trials, performed over a longer timeframe are required to show a clear benefit over conventional and other loading types.
本系统文献综述的目的是比较传统（延迟）加载和即刻加载种植体的临床性能。使用多个电子数据库，以“即刻加载”“牙种植体”“即刻功能”“早期加载”“口腔种植体”“即刻修复”和“系统综述”为关键词，对1995年至2012年间发表的研究进行了文献检索。电子检索辅以在牙科期刊中的手工检索以及对所选文章的交叉引用。如果研究分析了种植体即刻加载方案的成功率，并重点关注随机对照临床试验，则考虑将其纳入。从文献中提取的临床研究中，有120项研究符合纳入标准并被纳入本系统综述。这些研究包括涉及即刻加载种植体成功率与传统加载种植体成功率一致的试验，这些即刻加载种植体采用了即刻加载方案或其他加载方案。根据研究结果，有证据表明即刻加载方案显示出较高的种植体存活率，在某些临床情况下可谨慎推荐使用。然而，需要在更长时间内进行的具有高证据水平的研究，尤其是随机对照试验，以证明其比传统和其他加载类型具有明显优势。
