This study aimed to compare implant positioning accuracy and patient-centered results between static and dynamic computer-assisted implant surgery (s-CAIS and d-CAIS) in edentulous jaws.
The current study retrospectively evaluated a total of 110 implants placed in 22 fully edentulous patients via s-CAIS or d-CAIS (n = 11). The accuracy of implant positioning was assessed by measuring the implant's angular deviation and deviation at the platform and apex from the preoperative design postoperatively. Patient-centered results, including preoperative and intraoperative patient-reported experiences and postoperative patient-reported outcomes, were extracted from the medical records. The nested t test and chi-square test were used to compare accuracy and patient-centered results between s-CAIS and d-CAIS postoperatively.
The implants in the s-CAIS group showed significantly smaller angular deviation (2.32 ± 1.23°) than those in the d-CAIS group (3.87 ± 2.75°). In contrast, the platform and apical deviation were significantly larger in s-CAIS (1.56 ± 1.19 mm and 1.70 ± 1.09 mm, respectively) than d-CAIS (1.02 ± 0.45 mm and 1.00 ± 0.51 mm, respectively). Furthermore, the implants in the s-CAIS group deviated significantly (p < 0.001) more toward the coronal direction than those in the d-CAIS group. Notably, all patients in the s-CAIS group reported an obvious foreign body sensation during surgery, representing a significant difference from the d-CAIS group.
Compared to s-CAIS, d-CAIS is a reliable technique for the placement of multiple implants in fully edentulous patients with less linear deviation and less foreign body sensation.
The retrospective study was registered on the Chinese Clinical Trial Registry on August 8, 2022, with registration number No. ChiCTR2200062484.
Despite the increasing use of computer- assisted implant surgery in fully edentulous patients, clinical evidence comparing implant positioning accuracy and patient-centered results between static and dynamic CAIS systems is scarce. Our study demonstrated that compared to s-CAIS, d-CAIS is a reliable technique for the placement of multiple implants in fully edentulous patients with less linear deviation.
本研究旨在比较无牙颌中静态和动态计算机辅助种植手术（s-CAIS 和 d-CAIS）的种植体定位准确性和以患者为中心的结果。
本研究回顾性评估了通过 s-CAIS 或 d-CAIS（n=11）植入 22 名完全无牙颌患者的总共 110 个种植体。术后通过测量种植体的角偏差和平台及根尖处与术前设计的偏差来评估种植体定位的准确性。从病历中提取以患者为中心的结果，包括术前和术中患者报告的体验以及术后患者报告的结果。术后使用嵌套 t 检验和卡方检验比较 s-CAIS 和 d-CAIS 之间的准确性和以患者为中心的结果。
s-CAIS 组的种植体角偏差明显小于 d-CAIS 组（2.32±1.23°比 3.87±2.75°）。相比之下，s-CAIS 的平台和根尖偏差明显更大（分别为 1.56±1.19mm 和 1.70±1.09mm），而 d-CAIS 为 1.02±0.45mm 和 1.00±0.51mm。此外，s-CAIS 组的种植体明显向冠方方向偏斜（p<0.001）。值得注意的是，s-CAIS 组的所有患者在手术中均报告明显异物感，与 d-CAIS 组有显著差异。
与 s-CAIS 相比，d-CAIS 是一种在完全无牙颌患者中放置多个种植体的可靠技术，线性偏差较小，异物感较轻。
该回顾性研究于 2022 年 8 月 8 日在中国临床试验注册中心注册，注册号为 ChiCTR2200062484。
尽管计算机辅助种植手术在完全无牙颌患者中的应用日益增多，但比较静态和动态 CAIS 系统之间种植体定位准确性和以患者为中心的结果的临床证据仍然缺乏。我们的研究表明，与 s-CAIS 相比，d-CAIS 是一种在完全无牙颌患者中放置多个种植体的可靠技术，线性偏差较小。
