. The information available about osseointegration and the bone to implant interaction of zirconia implants with various surface modifications is still far from sufficient. . The purpose of this systematic review and meta-analysis was to evaluate and compare zirconia dental implants with different surface topographies, with a focus on bone to implant contact and removal torque. . The systematic review of the extracted publications was performed to compare the bone to implant contact (BIC) with removal torque (RT) values of titanium dental implants and machined and surfaced modified zirconia implants. . A total of fifteen articles on BIC and RT values were included in the quantitative analysis. No significant difference in the BIC values was observed between titanium and machined zirconia implants ( = 0.373; 95% CI: -0.166 to 0.443). However, a significantly better BIC values were observed for acid etched zirconia implants compared with those of titanium implants ( = 0.032; 95% CI: 0.068 to 1.461). Unmodified zirconia implants showed favorable BIC values compared to modified-surface zirconia implants ( = 0.021; 95% CI: -0.973 to -0.080). . Acid etched zirconia implants may serve as a possible substitute for successful osseointegration.
. 关于氧化锆种植体在各种表面改性情况下的骨结合以及骨与种植体相互作用的现有信息仍然远远不够充分。. 本系统评价和荟萃分析的目的是评估和比较具有不同表面形貌的氧化锆牙科种植体，重点关注骨与种植体的接触以及去除扭矩。. 对提取的出版物进行系统评价，以比较钛牙科种植体以及机械加工和表面改性氧化锆种植体的骨与种植体接触（BIC）和去除扭矩（RT）值。. 定量分析共纳入了15篇关于BIC和RT值的文章。钛种植体和机械加工氧化锆种植体之间的BIC值未观察到显著差异（ = 0.373；95%置信区间：-0.166至0.443）。然而，与钛种植体相比，酸蚀氧化锆种植体的BIC值显著更好（ = 0.032；95%置信区间：0.068至1.461）。与表面改性氧化锆种植体相比，未改性氧化锆种植体显示出良好的BIC值（ = 0.021；95%置信区间：-0.973至-0.080）。. 酸蚀氧化锆种植体可能作为成功骨结合的一种可能替代物。
