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.

摘要

目的

本回顾性队列研究旨在确定由杆状中间结构支撑的覆盖义齿在四颗牙种植体上的修复成功率、使用静态计算机辅助种植手术（sCAIS）植入种植体的存活率以及种植体植入的准确性。

方法

在虚拟规划后，对纳入患者的无牙颌进行全引导手术以植入种植体。使用混合工作流程制作种植体支持的覆盖义齿。患者每隔六个月安排进行临床和影像学评估以及口腔卫生治疗。通过叠加术后桌面扫描和虚拟规划来评估种植体植入的准确性。

结果

本研究共为13名患者（10名男性，3名女性；平均年龄：69.3±4.84岁）植入60颗种植体并交付15副覆盖义齿（11副上颌和4副下颌）。患者随访23.23±11.79个月。修复成功率、种植体累积存活率和种植体成功率分别为100%、98.33%和93.33%。种植体周围炎的发生率为3.33%，种植体周围黏膜炎在种植体水平和患者水平的发生率分别为28.33%和46.15%。对于sCAIS手术，角度偏差为3.19±1.73°，冠状面整体偏差为1.51±0.68mm，根尖整体偏差为1.56mm（中位数）；范围：3.77mm。
