Abstract

Objectives

This retrospective cohort study aimed to determine the prosthetic success of overdentures supported by bar mesostructures on four dental implants, the survival rate of the implants placed using static Computer Assisted Implant Surgery (sCAIS), and the accuracy of implant placement.

Methods

Fully guided surgery was performed to place implants in the edentulous jaws of patients enrolled following virtual planning. Implant-supported overdentures were manufactured using a hybrid workflow. Patients were scheduled for clinical and radiographical evaluations and oral hygiene treatment at six-monthly intervals. The accuracy of implant placement was assessed by superimposing the postoperative desktop scans and the virtual plans.

Results

In total 60 implants were placed and 15 overdentures (11 maxillary and 4 mandibular) were delivered for 13 patients (10 male, 3 female; mean age: 69.3 ± 4.84 years) in this study. Patients were followed up for 23.23 ± 11.79 months. The prosthetic success, cumulative implant survival, and implant success rate were 100 %, 98.33 % and 93.33 % respectively. The incidence of periimplantitis was 3.33 % and 7.69, the incidence of periimplant mucositis was 28.33 % and 46.15 % on implant and patient level respectively. For the sCAIS procedures, the angular deviation was 3.19 ± 1.73 °, coronal global deviation was 1.51 ± 0.68 mm, and apical global deviation was 1.56 mm (median); range: 3.77 mm.

Conclusion

Overdentures supported by bar mesostructures on four dental implants placed using sCAIS demonstrate a high rate of prosthetic success and a clinically acceptable incidence of biological and biomechanical complications during the two-year follow-up.

Clinical significance

Delivering an overdenture supported by a bar mesostructure on four dental implants placed using sCAIS is a predictable treatment modality in the management of the edentulous patient.

一项评估全引导静态计算机辅助种植手术后种植覆盖义齿成功的回顾性研究。

目的：本回顾性队列研究旨在确定四种牙种植体上bar介观结构覆盖义齿的修复成功率，采用静态计算机辅助种植手术（sCAIS）放置种植体的存活率以及种植体放置的准确性。方法：在虚拟计划下，对入组的无牙颌患者进行完全引导手术植入种植体。采用混合工作流程制作种植支撑覆盖义齿。患者被安排每六个月进行一次临床和放射学评估和口腔卫生治疗。通过叠加术后桌面扫描和虚拟计划来评估植入物放置的准确性。结果：13例患者（男10例，女3例）共植入种植体60枚，植入覆盖义齿15枚（上颌11枚，下颌4枚）；平均年龄：69.3±4.84岁。随访时间为23.23±11.79个月。假体成功率为100%，累积种植体存活率为98.33%，种植体成功率为93.33%。种植体水平和患者水平种植体周围炎的发生率分别为3.33%和7.69%，种植体和患者水平种植体周围黏膜炎的发生率分别为28.33%和46.15%。sCAIS手术的角度偏差为3.19±1.73°，冠状整体偏差为1.51±0.68 mm，根尖整体偏差为1.56 mm（中位数）；结论：在为期两年的随访中，使用sCAIS在4个种植体上放置条状介孔结构支撑的覆盖义齿显示出高的修复成功率和临床上可接受的生物和生物力学并发症发生率。临床意义：使用sCAIS在四颗种植体上放置一根棒状介孔结构的覆盖义齿，是一种可预测的无牙患者的治疗方式。

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
