There is limited evidence for the use of zirconium dioxide implants in immediate implant placement as well as for related immediate loading protocols. The aim of this retrospective study was to investigate the survival rate, success and patient satisfaction of immediately placed zirconia implants compared to delayed placed implants.
The study included 58 partially edentulous patients who were treated between 2013 and 2015 with immediate and delayed transgingival healing zirconium dioxide implants (SDS, Kreuzlingen/ Switzerland). In addition to survival and success rate, marginal bone loss was assessed using radiographs and soft tissue was evaluated using Pink Esthetic Score. Oral health-related quality of life was investigated prospectively using a modified OHIP questionnaire.
The cumulative survival rate of all implants included was 92% with 88% classified as full success. No significant difference was found between the bone levels of immediately and delayed placed and immediately and delayed loaded implants. The mean Pink Esthetic Score after final prosthetic rehabilitation was 12.2/14 points indicating excellent esthetic clinical results. Analysis of the OHIP questionnaire showed a mean value of 0.54/100 points reflecting a high patient satisfaction.
Immediate and delayed placed as well as loaded zirconium dioxide implants showed excellent results regarding implant success and survival in this study. Zirconium dioxide implants may ensure excellent esthetic results and high patient satisfaction.
氧化锆植入物在即刻种植中的应用以及相关的即刻负载方案的证据有限。本回顾性研究旨在比较即刻植入氧化锆种植体与延迟植入种植体的存活率、成功率和患者满意度。
该研究纳入了 58 名部分缺牙患者，他们于 2013 年至 2015 年间接受了即刻和延迟经牙龈愈合氧化锆种植体（SDS，瑞士克鲁岑）的治疗。除了存活率和成功率外，还使用放射照片评估边缘骨丢失，使用 Pink 美学评分评估软组织。使用改良的 OHIP 问卷前瞻性调查口腔健康相关生活质量。
所有纳入的种植体的累积存活率为 92%，其中 88%被归类为完全成功。即刻和延迟放置以及即刻和延迟加载种植体的骨水平之间没有发现显著差异。最终修复后平均 Pink 美学评分为 12.2/14 分，表明具有极好的临床美学效果。OHIP 问卷的分析显示平均得分为 0.54/100 分，反映了患者的高度满意度。
在本研究中，即刻和延迟放置以及加载的氧化锆种植体在种植体成功率和存活率方面均取得了优异的结果。氧化锆种植体可以确保出色的美学效果和高患者满意度。
