摘要

目的:评估一种新型两片式氧化锆种植体系统螺钉保留玻璃陶瓷冠修复12个月的存活率和成功率,包括评估骨水平、软组织参数和患者报告的结果测量。方法:24例患者在愈合部位接受单片式二氧化锆种植体(CERALOG®Hexalobe)。6个月的愈合期后,种植体在PEKK临时基台上使用临时螺钉保留冠,然后在PEKK基台上使用最终的二硅酸锂冠(IPS e.max Press)。在植入、再入、最终加载、12个月的随访以及患者报告的结果测量时进行临床和影像学检查。结果:种植体12个月存活率为60.9%。9个植入物丢失:2个是由于再入时缺乏骨整合,4个是由于装载后的活动能力,3个是由于装载后冠状三分之一的骨折。存活的种植体显示出稳定的软组织参数,12个月时平均探测袋深度为2.7±0.7 mm。从假体肩关节到首次骨接触的平均距离从加载时的1.9±0.6 mm减少到12个月时的1.4±0.6 mm。存活的种植体患者在功能和美观方面的满意度得分很高(4.8±0.4)。结论:两片式氧化锆种植体带螺钉固位修复体的成活率不理想。陶瓷种植体与螺钉保留假体修复体的结合可能是观察到的更高失败率的原因。作为一项样本量相对较小的试点研究,这些发现应该通过更大的多中心研究来证实这些初步结果。

Prospective clinical study to evaluate the success and survival of two-piece zirconia implants: a single-center study. 12-month results.

Purpose: To evaluate the survival and success rates of a novel two-piece zirconia implant system restored with screw-retained glass-ceramic crowns over 12 months, including assessment of bone levels, soft tissue parameters, and patient-reported outcome measures.

Methods: Twenty-four patients received single two-piece zirconia implants (CERALOG® Hexalobe) in healed sites. After a 6-month healing period, implants received provisional screw-retained crowns on PEKK temporary abutments, followed by definitive lithium disilicate crowns (IPS e.max Press) on PEKK abutments. Clinical and radiographic examinations were performed at implant placement, re-entry, definitive loading, and 12-month follow-up, along with patient-reported outcome measures.

Results: The implant survival rate at 12 months was 60.9%. Nine implants were lost: two due to lack of osseointegration at re-entry, four due to mobility after loading, and three due to fractures in the coronal third after loading. Surviving implants showed stable soft tissue parameters with mean probing pocket depths of 2.7 ± 0.7 mm at 12 months. The mean distance from implant shoulder to first bone contact decreased from 1.9 ± 0.6 mm at loading to 1.4 ± 0.6 mm at 12 months. Patients with surviving implants reported high satisfaction scores (4.8 ± 0.4) for function and aesthetics.

Conclusions: The two-piece zirconia implant system with screw-retained restorations showed unsatisfactory survival rates. The combination of ceramic implants with screw-retained prosthetic restorations may have contributed to the higher failure rates observed. As a pilot study with a relatively small sample size, these findings should be confirmed by larger multicenter studies to validate these preliminary results.
