Restoring teeth with dental implants has become the gold standard in recent years, especially in the esthetic zone. However, limited amount of available bone as well as limited interdental space in the anterior zone may create problems for implant treatment. Narrow diameter implants (NDI) may be a treatment option to resolve the above-mentioned limitations and providing minimally invasive implant therapy without additional regenerative procedures. In this retrospective study, a comparison of clinical and radiographic outcomes between one-piece and two-piece titanium-made NDIs was done with the follow-up of two years after loading. Twenty-three NDI cases were analyzed, 11 in the one-piece implant group (group one) and 12 in the two-piece implant group (group two). The outcomes were implant and prosthetic failures, any complications occurred, peri-implant bone level changes, and as well as the Pink Esthetic score. No implant or prosthetic failures, as well as, no complications were reported at the two-year follow-up examination. At the same time the marginal bone loss was 0.23 ± 0.11 in the group one and 0.18 ± 0.12 in the group two. Difference was not statistically significant ( = 0.3339). The Pink Esthetic Score, recorded two years after definitive loading, was 12.6 ± 0.97 in the group one and 12.2 ± 0.92 in the group two, with no statistically significant difference between groups ( = 0.3554). With the limitations of the present study, including the small sample size and short follow-up, it is possible to conclude that either one and two-piece NDI can be successfully used to restore lateral incisors with comparable results within the two years of follow-up.
近年来，使用牙种植体修复牙齿已成为金标准，尤其是在美学区域。然而，前牙区可用骨量有限以及牙间隙狭窄可能给种植治疗带来问题。窄直径种植体（NDI）可能是一种解决上述局限性的治疗选择，可提供微创种植治疗且无需额外的骨增量手术。在这项回顾性研究中，对一体式和两件式钛制NDI的临床和影像学结果进行了比较，并在加载后随访两年。分析了23例NDI病例，一体式种植体组（一组）11例，两件式种植体组（二组）12例。观察指标包括种植体和修复体失败情况、发生的任何并发症、种植体周围骨水平变化以及粉红美学评分。在两年的随访检查中，未报告种植体或修复体失败以及并发症。同时，一组的边缘骨吸收为0.23±0.11，二组为0.18±0.12。差异无统计学意义（P = 0.3339）。最终加载两年后记录的粉红美学评分，一组为12.6±0.97，二组为12.2±0.92，组间差异无统计学意义（P = 0.3554）。鉴于本研究存在样本量小和随访时间短的局限性，可以得出结论，在两年的随访期内，一体式和两件式NDI均可成功用于修复侧切牙，结果相当。
