摘要
目的:本研究旨在比较完全引导的动态和静态计算机辅助种植体手术(CAIS)系统在美学区即刻种植体放置的准确性。方法:将40例符合条件的患者随机平均分为静态CAIS组(n = 20)和动态CAIS组(n = 20)。测量种植体入口、尖端的整体偏差以及放置和计划种植体位置之间的角度偏差,并将其作为主要结果进行比较。次要结果是种植体在中-远端、唇-腭和冠-根尖方向放置的偏差。结果:在即刻种植时,CAIS静态组和动态组的平均总入口偏差分别为0.99±0.63 mm和1.06±0.55 mm (p = 0.659),平均总尖偏差分别为1.50±0.75 mm和1.18±0.53 mm (p = 0.231)。静态CAIS组与动态CAIS组的角度偏差分别为3.07±2.18°和3.23±1.67°(p = 0.547)。静态和动态CAIS系统即刻种植体放置的精度参数无显著差异,除了动态CAIS组种植体在入牙时唇腭方向的偏差明显大于静态CAIS组(p = 0.005)。结论:本研究表明,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性。试验注册ChiCTR, ChiCTR2200056321。2022年2月3日注册,http://www.chictr.org.cn/showproj.aspx?proj=151348。
Comparison of the accuracy of immediate implant placement using static and dynamic computer-assisted implant system in the esthetic zone of the maxilla: a prospective study.
Purpose: 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.
Methods: 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.
Results: 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).
Conclusions: This study demonstrated that clinically acceptable accuracy of immediate implant placement could be achieved using static and dynamic CAIS systems. Trial registration ChiCTR, ChiCTR2200056321. Registered 3 February 2022, http://www.chictr.org.cn/showproj.aspx?proj=151348.
