Clinicians should be able to weigh the role of the main risk factors associated with early implant failure.
The aim of this meta-analysis was to assess the influence of different patient-related and implant-related risk factors on the occurrence of early implant failure.
In July, 2014 the main electronic databases were searched for studies reporting on early failures. Relevant papers were selected by 2 independent authors using predefined selection criteria. Three authors independently scored the included studies for quality assessment. The estimated odds ratios of the main risk factors from the selected papers were subjected to meta-analysis.
Nine studies were included. A total of 18,171 implants were meta-analyzed, of which 10,921 were analyzed for smoking, 15,260 for implant diameter, 16,075 for implant length, and 16,711 for implant location (maxilla vs mandible). The main significant risk factors for early implant failures were the smoking habit (odds ratio [OR], 1.7; 95% confidence interval [CI], 1.3, 2.3), implants shorter than 10 mm (OR, 1.6; 95% CI, 1.2, 2.2) and implants placed in the maxilla (OR, 1.3; 95% CI, 1.0, 1.6).
Clinicians should be aware of the increased risk of early failure in the presence of smokers, implants with reduced length, and implant-supported maxillary rehabilitation.
临床医生应能够权衡与早期种植失败相关的主要风险因素的作用。
本荟萃分析的目的是评估不同的患者相关和种植体相关风险因素对早期种植失败发生的影响。
2014年7月检索主要电子数据库，查找关于早期失败的研究报告。由2名独立作者根据预先确定的选择标准选择相关论文。3名作者独立对纳入研究进行质量评估评分。对所选论文中主要风险因素的估计比值比进行荟萃分析。
纳入9项研究。共对18171颗种植体进行了荟萃分析，其中10921颗分析了吸烟情况，15260颗分析了种植体直径，16075颗分析了种植体长度，16711颗分析了种植体位置（上颌与下颌）。早期种植失败的主要显著风险因素为吸烟习惯（比值比[OR]，1.7；95%置信区间[CI]，1.3，2.3）、长度小于10 mm的种植体（OR，1.6；95%CI，1.2，2.2）以及上颌种植体（OR，1.3；95%CI，1.0，1.6）。
临床医生应意识到，吸烟者、长度较短的种植体以及上颌种植支持修复存在早期失败风险增加的情况。
