Abstract

Statement of problem: Dynamic computer-assisted surgical implant placement (dCAIS) facilitates precise implant placement through a real-time tracking system, enabling single-visit treatment. However, an understanding of the learning curve associated with dCAIS in terms of differences between anterior and posterior implant placement is lacking.

Purpose: The purpose of this in vitro trial was to observe the learning curve for anterior and posterior implant placement in novice and experienced operators using dCAIS in a type-III bone model simulated maxilla.

Material and methods: Eight participants, including 4 novice and 4 experienced operators, were randomly assigned in blocks to either the anterior or posterior placement group. Before the experiment, the participants received video-training. Each participant performed 4 single implant placements per session with a 7 ±1 day wash-out period, totaling 5 practice sessions. Three-way repeated-measures analysis of variance (ANOVA) and 2-way ANOVA were used to analyze the effects of practice sessions, operator experience, and implant location on operating time and placement deviation. The operating time, coronal, depth, and angle deviations in each session were recorded and analyzed using repeated-measures ANOVA to express the learning curve (α=.05).

Results: The analysis of 160 implants showed significantly higher coronal and angle deviation in the posterior group than in the anterior group during the first and second practice session (P<.05), with no significant differences observed from the third to the fifth practice session; the anterior group exhibited consistent performance from the first practice session. Novice and experienced operators exhibited statistically different operating times, particularly during the first practice session (P<.05), with no differences in accuracy being observed (P>.05). Operating time decreased with the increasing number of practice sessions in all groups.

Conclusions: A learning curve for placing anterior implants with dCAIS may not be necessary for either novice or experienced operators. However, in posterior implant placement, a minimum of 3 practice sessions was found beneficial for both novice and experienced operators.

动态计算机辅助外科种植体置入术在新手和有经验的操作者中前路和后路种植体置入术的学习曲线比较:一项体外试验。
问题说明:动态计算机辅助外科植入物放置(dCAIS)通过实时跟踪系统促进精确植入物放置,实现单次就诊。然而,关于dCAIS在前路和后路种植体放置方面的差异的学习曲线的理解是缺乏的。目的:本体外试验的目的是观察新手和经验丰富的操作者在iii型骨模型模拟上使用dCAIS进行前、后牙种植的学习曲线。材料和方法:8名参与者,包括4名新手和4名有经验的操作者,随机分为前位组和后位组。在实验之前,参与者接受了视频训练。每位受试者每节进行4次单种植体放置,洗脱期为7±1天,共5节练习。采用三向重复测量方差分析(ANOVA)和双向方差分析(two -way ANOVA)分析练习时间、操作者经验和种植体位置对手术时间和放置偏差的影响。记录每次手术的操作时间、冠状、深度和角度偏差,并使用重复测量方差分析来表达学习曲线(α= 0.05)。结果:对160个种植体的分析显示,在第一次和第二次练习中,后牙组的冠状和角度偏差明显高于前牙组(p < 0.05)。各组手术时间随练习次数的增加而减少。结论:对于新手或有经验的操作者来说,使用dCAIS放置前路种植体的学习曲线可能是不必要的。然而,在后路植入中,至少3次练习对新手和有经验的操作者都是有益的。
