摘要

目的:了解单层和最小层状全弓氧化锆假体的中位无事件生存率和相对并发症发生率,并探讨假体并发症的危险因素。材料与方法:本回顾性队列研究共纳入129名受试者(173个假体)进行图表回顾,56名受试者(75个假体)进行临床随访。所有受试者均采用单弓或双弓整体或最小层状氧化锆种植体支持的假体。从图表中提取与患者、种植体和假体因素相关的数据。参加临床访问的小组被要求完成一份满意度问卷。对于该亚组,评估了以下临床措施:常规口腔内检查,咬合单元数量,假体两侧(右侧和左侧)的悬臂长度,假体高度,咬合方案和口腔卫生方法。根尖周围x线片是在患者最后一次拍摄x线片超过12个月之前获得的。结果:随访时间12个月~ 7.1年,平均1.9年。观察到的并发症包括种植体丢失、种植体周围炎、粘膜炎、化脓、窦道形成、口-窦间连通、种植体断裂、钛基脱粘、陶瓷碎裂、假体螺钉断裂或松动、对牙损伤、咔嗒声。并发症的数量不足以评估协变量对特定并发症风险的影响,如钛基脱粘(8个事件)、陶瓷碎裂(9个事件)和种植体周围炎(8个事件)。未调整的无事件中位生存时间为5.8年。所有假体中至少有一种并发症的比例为30%。在随访期间没有观察到假体丢失。结论:整体和最小层状氧化锆全弓种植体支持的假体显示出可接受的中位无事件生存时间。5 - 8个假体和常规(相对于颧骨)假体的无事件生存时间增加,并发症数量减少。有规律的召回方案降低了并发症的风险。患者对这些假体的满意度很高。

Retrospective Cohort Evaluation of Full-Arch Zirconia Implant-Supported Fixed Prostheses.

Objective: To determine the median event-free survival and relative complication rates of monolithic and minimally layered full-arch zirconia prostheses, as well as to identify risk factors for prosthesis complications. Materials and Methods: In this retrospective cohort study, a total of 129 subjects (173 prostheses) were included in the chart review and 56 subjects (75 prostheses) participated in a clinical follow-up visit. All subjects had either single- or dual-arch monolithic or minimally layered zirconia implant-supported prostheses. Data related to patient, implant, and prosthesis factors were extracted from charts. The subgroup that presented for a clinical visit were asked to complete a satisfaction questionnaire. For this subgroup, the following clinical measures were assessed: routine intraoral examination, number of occluding units, cantilever length on each side of the prosthesis (right and left), prosthesis height, occlusal scheme, and oral hygiene methods. Periapical radiographs were obtained when the last radiographs of the patient were taken more than 12 months prior. Results: The follow-up period ranged from 12 months to 7.1 years (mean: 1.9 years). Observed complications included implant loss, peri-implantitis, mucositis, purulence, sinus tract formation, oroantral communication, implant fracture, titanium base debonding, ceramic chipping, prosthetic screw fracture or loosening, damage to opposing teeth, and clicking sounds. There was an insufficient number of complications to evaluate the effect of covariates on the risk of specific complications, such as titanium base debonding (eight events), ceramic chipping (nine events), and peri-implantitis (eight events). The unadjusted event-free median survival time was 5.8 years. The proportion of all prostheses with at least one complication was 30%. There were no observed prosthesis losses during the follow-up period. Conclusion: Monolithic and minimally layered zirconia full-arch implant-supported prostheses demonstrate an acceptable median event-free survival time. Event-free survival times were increased and the number of complications was reduced in prostheses with five to eight implants and conventional (as opposed to zygomatic) implants. There was a reduced hazard of complications with a regular recall regimen. Patient satisfaction with these prostheses was high.

期刊介绍: Edited by Steven E. Eckert, DDS, MS ISSN (Print): 0882-2786 ISSN (Online): 1942-4434 This highly regarded, often-cited journal integrates clinical and scientific data to improve methods and results of oral and maxillofacial implant therapy. It presents pioneering research, technology, clinical applications, reviews of the literature, seminal studies, emerging technology, position papers, and consensus studies, as well as the many clinical and therapeutic innovations that ensue as a result of these efforts. The editorial board is composed of recognized opinion leaders in their respective areas of expertise and reflects the international reach of the journal. Under their leadership, JOMI maintains its strong scientific integrity while expanding its influence within the field of implant dentistry. JOMI’s popular regular feature "Thematic Abstract Review" presents a review of abstracts of recently published articles on a specific topical area of interest each issue.
