Limited clinical evidence has been reported in dental literature regarding zirconia dental implants. The aim of the present retrospective consecutive case series was to evaluate the clinical outcome of zirconia dental implants with 1 to 5 years of follow-up.
The clinical outcome of 24 implants in 12 consecutive patients (male 5, female 7) with a mean age of 55 years (range 27-86) is reported. Radiographic crestal bone level was assessed by the use of "ImageJ" software program. Gingival and plaque indices were recorded at baseline and latest follow-up.
The overall success rate of zirconia implants was 92%. Within the limitations of the present clinical evaluation, zirconia implants provided excellent clinical results and esthetic outcomes. A mean periimplant bone loss of 0.3 mm was measured in 33.3% of the implants and 66.7% were not affected by radiographic detectable periimplant bone loss. Two implants in two patients failed. Low gingival and plaque indices were predominant values for both interim and final restorations. The apparent less affinity to plaque accumulation may favor soft tissue health around zirconia dental implants and decrease the risk of inflammation or infection. Zirconia dental implant merits further investigation.
Zirconia dental implants are emerging as an option in clinical practice of implant dentistry providing stable clinical results and esthetic outcomes.
牙科文献中仅有有限的临床证据报道了氧化锆牙科种植体。本回顾性连续病例系列研究的目的是评估随访 1 至 5 年的氧化锆牙科种植体的临床效果。
报告了 12 例连续患者（男 5 例，女 7 例）24 枚种植体的临床结果，平均年龄为 55 岁（27-86 岁）。使用“ImageJ”软件程序评估了影像学牙槽嵴骨水平。在基线和最新随访时记录了牙龈和菌斑指数。
氧化锆种植体的总体成功率为 92%。在本临床评估的限制范围内，氧化锆种植体提供了出色的临床效果和美观效果。33.3%的种植体测量到平均种植体周围骨损失 0.3 毫米，66.7%的种植体不受影像学可检测到的种植体周围骨损失的影响。两名患者的两枚种植体失败。低牙龈和菌斑指数是中期和最终修复的主要值。氧化锆牙科种植体似乎对菌斑积累的亲和力较低，这可能有利于氧化锆牙科种植体周围的软组织健康，降低炎症或感染的风险。氧化锆牙科种植体值得进一步研究。
氧化锆牙科种植体作为种植牙科临床实践中的一种选择正在出现，提供了稳定的临床效果和美观效果。
