Abstract

Background: Various scanning methods aim to reduce intraoral scanner errors, yet no specific approach targets paediatric patients.

Aim: Evaluate continuous (C) and noncontinuous (NC) scanning patterns' impact on the trueness and duration of paediatric digital impressions.

Design: A standard pedodontic typodont model was scanned with a Trios 4 Move+ IOS using four scanning strategies. C1 and C2 followed continuous scanning from the right molars, with different directions. NC1 scanned noncontinuously from the right molar, with breaks every four teeth. NC2 began at the right primary incisor, with breaks after every three teeth. Each scan, performed five times by one researcher, was timed. Industrial scanning provided reference data. Deviations were analyzed using the MIXED procedure.

Results: NC1 had higher deviations in the lower jaw, whereas C1 and NC1 showed higher deviations in the upper jaw (p < .001). C1 had significantly higher deviations in the upper jaw than the lower jaw (p = .041). NC2 had the longest scanning time in both upper and lower jaws (p = .002).

Conclusion: Paediatric digital impressions benefit from starting at the anterior and incorporating breaks, although this increases scanning time.

扫描策略对儿科模型数字模型真实性和时间效率的影响。

背景：目的：评估连续（C）和非连续（NC）扫描模式对儿科数字印模的真实性和持续时间的影响：设计：使用 Trios 4 Move+ IOS 采用四种扫描策略对一个标准的正畸模型进行扫描。C1和C2从右臼齿开始连续扫描，扫描方向不同。NC1 从右臼齿开始非连续扫描，每隔四颗牙齿中断一次。NC2 从右侧主切牙开始，每隔三颗牙齿扫描一次。每次扫描由一名研究人员进行五次并计时。工业扫描提供参考数据。使用 MIXED 程序对偏差进行分析：结果：NC1 在下颌的偏差较大，而 C1 和 NC1 在上颌的偏差较大（p 结论：NC1 和 NC1 在下颌的偏差较大，而 C1 和 NC1 在上颌的偏差较大：儿科数字印模从前部开始并结合断裂处，虽然会增加扫描时间，但还是有好处的。

期刊介绍： The International Journal of Paediatric Dentistry was formed in 1991 by the merger of the Journals of the International Association of Paediatric Dentistry and the British Society of Paediatric Dentistry and is published bi-monthly. It has true international scope and aims to promote the highest standard of education, practice and research in paediatric dentistry world-wide. International Journal of Paediatric Dentistry publishes papers on all aspects of paediatric dentistry including: growth and development, behaviour management, diagnosis, prevention, restorative treatment and issue relating to medically compromised children or those with disabilities. This peer-reviewed journal features scientific articles, reviews, case reports, clinical techniques, short communications and abstracts of current paediatric dental research. Analytical studies with a scientific novelty value are preferred to descriptive studies. Case reports illustrating unusual conditions and clinically relevant observations are acceptable but must be of sufficiently high quality to be considered for publication; particularly the illustrative material must be of the highest quality.
