Abstract：
OBJECTIVE: To describe the clinical and radiographic performance and survival rate of a new two-piece ceramic implant system after at least 12 months of follow-up.
METHODS: Sixty-five implants were placed and followed up for at least 12 months (12.3 ± 1.5), in 50 patients. The implants were installed both in fresh extraction sockets and in healed sites and received provisional restoration when the clinical insertion torque was greater than 35Ncm. The primary results describe the survival rate of these implants. Clinical performance was evaluated through the evaluation of the Pink Esthetic Score (PES) and the degree of satisfaction of the patients. Bone loss was measured through radiographic measurements of the marginal bone loss in the mesial (MBLM) and distal (MBLD) sites.
RESULTS: The survival rate was 98.5%. The average MBLM was 0.24 mm (± 0.53) and the MBLD was 0.27 mm (± 0.57). A statistical difference was observed only when comparing immediate implants with delayed ones (MBLM - p = 0.046 and MBLD - p = 0.028) and when they received immediate provisionalization or not (MBLM - p = 0.009 and MBLD - p = 0.040). The PES before the intervention (T0) was 13.4 (± 0.8) and the PES at T2 (12-month follow-up) was 12.9 (± 1.5) (p = 1.14).
CONCLUSIONS: The new two-piece ceramic implant used in the present study showed predictable and reliable results, similar to those found with titanium implants after one year of follow-up.
CONCLUSIONS: These implants can be used as an alternative to titanium implants in terms of the marginal bone loss and the degree of patient satisfaction.

摘要：
目的：描述一种新的两件式陶瓷植入物系统在至少12个月的随访后的临床和影像学表现以及存活率。
方法：放置种植体65个，随访至少12个月（12.3±1.5），50名患者当临床插入扭矩大于35Ncm时，将植入物安装在新鲜的拔牙座和愈合部位，并获得临时修复。主要结果描述了这些植入物的存活率。通过对粉红美学评分（PES）和患者满意度的评估来评估临床表现。骨损失是通过对内侧（MBLM）和远端（MBLD）部位的边缘骨损失进行放射学测量来测量的。
结果：生存率为98.5%。平均MBLM为0.24mm（±0.53），MBLD为0.27mm（±0.57）。仅在比较即时植入物与延迟植入物（MBLM-p=0.046和MBLD-p=0.028）以及是否接受即时预治疗（MBLM-p=0.009和MBLD-p=0.040）时才观察到统计学差异。干预前的PES（T0）为13.4（±0.8），T2时的PES（12个月随访）为12.9（±1.5）（p=1.14）。
结论：本研究中使用的新型两件式陶瓷植入物显示出可预测和可靠的结果，与经过一年的随访发现的钛植入物相似。
结论：就边缘骨丢失和患者满意度而言，这些植入物可用作钛植入物的替代品。
