To assess the accuracy and patient reported outcome measures (PROMs) of the computer-guided "double factor" technique for treating fully edentulous patients.
A proof of concept prospective study was designed. Ten consecutive patients requiring full arch dental implant supported rehabilitation in a private practice were enrolled between October 2021 and March 2022. All patients were treated by means of an All-on-four®, and implants were planned and placed according to the "double factor" technique. This technique merges the static and dynamic computer-guided surgical approach in the same surgery. The primary outcome was the accuracy of implant placement, measured by overlapping post- and pre-operative cone-beam computerized tomography with the implant planning. Additionally, PROMs and patient quality of life after surgery were evaluated using different questionnaires. Descriptive and bivariate data analyses were performed. Statistical significance was considered for p < 0.05.
A total of 48 implants were placed using the "double factor" technique, and 12 full-arch immediate loading prostheses were delivered. The mean angular deviation was 3.74° (standard deviation [SD]: 2). The total linear deviation at the apex and platform of the implant was 1.25 mm (SD: 0.55) and 1.42 mm (SD: 0.64), respectively. No statistically significant differences were found between tilted and axial implants, the upper and lower jaw, or the right and left side. High self-reported satisfaction was registered, and the Oral Health Impact Profile-14 (OHIP-14) score improved postoperatively (p = 0.002).
The "double factor" technique is a valid and accurate treatment approach for fully edentulous patients.
The double factor technique merges the advantages of both the dynamic and static computer assisted surgery approaches, affording accurate and predictable results when treating fully edentulous patients in a minimally invasive manner.
评估计算机引导的“双因素”技术治疗全口无牙患者的准确性及患者报告结局指标（PROMs）。
设计了一项概念验证前瞻性研究。2021年10月至2022年3月期间，连续纳入了10例在私人诊所需要全牙弓种植体支持修复的患者。所有患者均采用All-on-four®治疗，种植体根据“双因素”技术进行规划和植入。该技术在同一手术中融合了静态和动态计算机引导手术方法。主要结局是种植体植入的准确性，通过术后和术前锥形束计算机断层扫描与种植体规划的重叠来测量。此外，使用不同问卷评估术后的PROMs和患者生活质量。进行了描述性和双变量数据分析。p < 0.05被认为具有统计学意义。
使用“双因素”技术共植入48枚种植体，交付了12个全牙弓即刻负重修复体。平均角度偏差为3.74°（标准差[SD]：2）。种植体根尖和平台处的总线性偏差分别为1.25 mm（SD：0.55）和1.42 mm（SD：0.64）。在倾斜种植体与轴向种植体、上颌与下颌、右侧与左侧之间未发现统计学显著差异。患者自我报告满意度较高，术后口腔健康影响程度量表-14（OHIP-14）评分有所改善（p = 0.002）。
“双因素”技术是治疗全口无牙患者的一种有效且准确的治疗方法。
双因素技术融合了动态和静态计算机辅助手术方法的优点，在以微创方式治疗全口无牙患者时能提供准确且可预测的结果。
