The aim of this work was to clinically and radiographically evaluate survival and success rate of zirconia dental implants positioned in premolar area during a follow-up period of at least 12 months up to 24 months.
Sixteen patients were treated with 26 zirconia implants. All implants received immediate temporary restorations and 6 months after surgery were definitively restored. Twelve to 14 months after implant insertion, a clinical-radiographical evaluation was performed in order to estimate peri-implant tissues health and peri-implant marginal bone loss.
The survival rate was 96.16%. The success rate was 91.6%.
Because of the limited number of implants, conclusions may not be considered significant even if results are encouraging. Further scientific information regarding clinical use of zirconia dental implants are needed, as well as prospective long-term clinical studies in order to understand if zirconia implants may represent a valid alternative to titanium implants.
本研究旨在通过临床和影像学方法评估位于前磨牙区的氧化锆牙种植体在至少12个月至24个月的随访期内的存活率和成功率。
16例患者接受了26颗氧化锆种植体治疗。所有种植体均接受即刻临时修复,并在术后6个月进行最终修复。种植体植入后12至14个月,进行临床影像学评估,以评估种植体周围组织健康状况和种植体周围边缘骨丢失情况。
存活率为96.16%,成功率为91.6%。
由于种植体数量有限,即使结果令人鼓舞,结论也可能不具有显著性。需要更多关于氧化锆牙种植体临床应用的科学信息,以及前瞻性长期临床研究,以了解氧化锆种植体是否可成为钛种植体的有效替代物。
