本研究旨在比较完全引导的动态和静态计算机辅助种植手术（CAIS）系统在美学区即刻种植体植入的准确性。共40名需要立即在美学区植入种植体的合格患者被随机平均分配到静态CAIS组（n = 20）或动态CAIS组（n = 20）。作为主要结局，测量并比较入口、顶点的总体偏差以及植入位置与计划植入位置之间的角度偏差。次要结局是种植体放置在近中-远中、唇-腭和冠-尖方向的偏差。对于立即种植体放置，静态和动态CAIS组的平均全局入口偏差分别为0.99 ± 0.63 mm和1.06 ± 0.55 mm（p = 0.659），而平均全局顶点偏差分别为1.50 ± 0.75 mm和1.18 ± 0.53 mm（p = 0.231）。静态和动态CAIS组的角度偏差分别为3.07 ± 2.18度和3.23 ± 1.67度（p = 0.547）。静态和动态CAIS系统之间即刻种植体放置的准确性参数没有观察到显著差异，除了动态CAIS组中种植体在唇-腭方向上的入口偏差比静态CAIS显著更偏向唇侧（p = 0.005）。本研究证明，使用静态和动态CAIS系统可以实现临床可接受的即刻种植体放置准确度。试验注册ChiCTR，ChiCTR 2200056321。2022年2月3日注册，http://www.chictr.org.cn/showproj.aspx?项目=151348
This study aimed to compare the accuracy of fully guided between dynamic and static computer-assisted implant surgery (CAIS) systems for immediate implant placement in the esthetic zone. A total of 40 qualified patients requiring immediate implant placement in the esthetic zone were randomly and equally assigned to either static CAIS group (n = 20) or dynamic CAIS groups (n = 20). Global deviations at entry, apex, and angular deviation between placed and planned implant position were measured and compared as primary outcomes. Secondary outcomes were the deviation of implant placement at mesial–distal, labial–palatal, and coronal–apical directions. For the immediate implant placement, the mean global entry deviations in static and dynamic CAIS groups were 0.99 ± 0.63 mm and 1.06 ± 0.55 mm (p = 0.659), while the mean global apex deviations were 1.50 ± 0.75 mm and 1.18 ± 0.53 mm (p = 0.231), respectively. The angular deviation in the static and dynamic CAIS group was 3.07 ± 2.18 degrees and 3.23 ± 1.67 degrees (p = 0.547). No significant differences were observed for the accuracy parameters of immediate implant placement between static and dynamic CAIS systems, except the deviation of the implant at entry in the labial–palatal direction in the dynamic CAIS group was significantly more labial than of the static CAIS (p = 0.005). This study demonstrated that clinically acceptable accuracy of immediate implant placement could be achieved using static and dynamic CAIS systems. Trial registration ChiCTR, ChiCTR2200056321.
