摘要

目的比较聚醚酮酮基基（PEKK）和氧化锆基基与钛基基和钛基基的累积生存期和技术并发症。材料与方法60名受试者随机均匀分配接受氧化锆或钛种植体。生存和技术并发症在冠植入后6周（基线）至36个月进行评估。假设钛组和氧化锆组之间的差异不超过10%，将sic的累积生存率作为非劣效性设计进行分析。根据改良的USPHS标准和粉红色美学评分（PES）评估技术并发症。结果氧化锆组早期种植失败3例；全部修改成功。在基线后，氧化锆组中有三个种植体由于骨整合不足而丢失，因此即使没有一个种植体失败，也必须将种植体归类为失败。氧化锆组的非劣效性尚未得到证实，因为累积生存率比钛组（100%）低10.7%。技术并发症发生率低，两组间差异无统计学意义。与基线相比，PESs显著改善，12个月时各组间无显著差异。结论PEKK基牙复合基牙可替代钛基牙复合基牙与钛基牙复合基牙。然而，必须考虑到氧化锆种植体的骨整合率较低。试验注册本研究已在德国临床试验注册（Deutsches Register Klinischer studen）注册（编号：DRKS00014866）。

A Randomised Controlled Trial Evaluating 3-Year Survival Rates and Technical Complications of Screw-Retained Hybrid Abutment Crowns on Two-Piece Zirconia and Titanium Implants.

OBJECTIVES This study compares the cumulative survival and technical complications of screw-retained implant-supported lithium disilicate crowns (SICs) on polyether ketone ketone (PEKK) base abutments and zirconia implants with those of titanium base abutments and titanium implants. MATERIALS AND METHODS Sixty participants were randomly and evenly assigned to receive zirconia or titanium implants. Survival and technical complications were assessed at 6 weeks after crown placement (baseline) up to 36 months. The cumulative survival of the SICs was analysed as a non-inferiority design, assuming that the difference between the titanium group and the zirconia group is not more than 10%. Technical complications were assessed based on modified USPHS criteria and Pink Aesthetic Score (PES). RESULTS In the zirconia group, three early implant failures occurred; all of them were successfully revised. After baseline, three implants in the zirconia group were lost due to insufficient osseointegration, and therefore the SICs have to be categorised as failures even though none of the SICs failed. The non-inferiority of the zirconia group could not be confirmed, as the cumulative survival was 10.7% lower compared to the titanium group (100%). The technical complication rate was low, with no statistically significant difference between the groups. The PESs improved significantly compared to baseline, with no significant difference between the groups at 12 months. CONCLUSION Hybrid abutment SICs with PEKK base abutments on two-piece zirconia implants could be an alternative to hybrid abutments SICs with titanium base on titanium implants. However, the lower osseointegration rate of the zirconia implants has to be considered. TRIAL REGISTRATION This study was registered in the German Clinical Trial Register (Deutsches Register Klinischer Studien) (number: DRKS00014866).

期刊介绍： Clinical Oral Implants Research conveys scientific progress in the field of implant dentistry and its related areas to clinicians, teachers and researchers concerned with the application of this information for the benefit of patients in need of oral implants. The journal addresses itself to clinicians, general practitioners, periodontists, oral and maxillofacial surgeons and prosthodontists, as well as to teachers, academicians and scholars involved in the education of professionals and in the scientific promotion of the field of implant dentistry.
