BACKGROUND
Computer-assisted implant surgery (CAIS) can facilitate accuracy of single implant placement, but little is known with regards to parallelism between multiple implants.
PURPOSE
To compare the accuracy of position and parallelism of two implants, using static and dynamic CAIS systems.
MATERIALS AND METHODS
Thirty patients received two implants (60 implants) randomly allocated to two different CAIS systems. Optimal implant position and absolute parallelism was planned based on preoperative cone beam CT (CBCT). Patients received implants with a surgical guide (static CAIS, n = 30) or real-time navigation (dynamic CAIS, n = 30). Implant three-dimensional deviation and parallelism was calculated after surgery.
RESULTS
The mean 3D deviation in the static and dynamic CAIS group at implant platform were 1.04 ± 0.67 vs 1.24 ± 0.39 mm, at apex were 1.54 ± 0.79 vs 1.58 ± 0.56 mm and angulation were 4.08° ± 1.69° vs 3.78° ± 1.84°, respectively. The angle deviations between two placed implants (parallelism) in static and dynamic CAIS groups were 4.32° ± 2.44° and 3.55° ± 2.29°, respectively. There were no statistically significant differences in all parameters between groups.
CONCLUSION
Static and dynamic CAIS provides similar accuracy of the 3D implant position and parallelism between two implants.
背景
计算机辅助种植手术（CAIS）可以提高单颗种植体植入的准确性，但对于多颗种植体之间的平行度，我们知之甚少。
目的
比较静态和动态 CAIS 系统在位置和多颗种植体之间的平行度方面的准确性。
材料和方法
30 名患者随机接受了两颗种植体（共 60 颗种植体），并分别使用两种不同的 CAIS 系统。基于术前锥形束 CT（CBCT）规划最佳种植体位置和绝对平行度。患者接受了带有手术导板的种植体（静态 CAIS，n = 30）或实时导航（动态 CAIS，n = 30）。术后计算种植体的三维偏差和平行度。
结果
在静态和动态 CAIS 组中，种植体平台处的平均三维偏差分别为 1.04 ± 0.67mm 和 1.24 ± 0.39mm，根尖处分别为 1.54 ± 0.79mm 和 1.58 ± 0.56mm，角度偏差分别为 4.08° ± 1.69°和 3.78° ± 1.84°。在静态和动态 CAIS 组中，两个植入物之间的角度偏差（平行度）分别为 4.32° ± 2.44°和 3.55° ± 2.29°。两组间所有参数均无统计学差异。
结论
静态和动态 CAIS 提供了类似的三维种植体位置和两颗种植体之间的平行度准确性。
