The aim is to demonstrate the validity of the monitoring through intraoral scanner of the dental movements and the real impact, advantages, and convenience, in terms of treatment time and efficiency gain, to frequently monitor a patient with the scanner application.
A movement control of palatally impacted canines was performed, surgically treated with laser opercolectomy. Three-dimensional models of the patient's dental arch were obtained with intraoral scanner during a monitoring time of 4 months. The STL (Standard Triangle Language) files were superimposed with the 3D models extrapolated from the pre-operative CT (Computerized Tomography). The measurements of eruption, exposed palatal and vestibular areas, and distances between the canines and the incisors were performed, using digital technologies and with a digital caliber.
Descriptive and inferential statistical analysis of the data obtained from both conventional and digital monitoring has been realized and performing the T Student Test for paired data.
The advantages of digital monitoring are numerous, like the possibility to reduce the error of method caused by manual measurement on plaster casts and the possibility to compare the pattern and amount of eruption of the canine in the same patient overtime.
本研究旨在通过口内扫描仪监测牙齿的移动，以及在治疗时间和效率方面的实际影响、优势和便利性，来证明这种监测的有效性。本研究对 1 例腭侧埋伏尖牙患者进行了运动控制，并采用激光外科切除术进行了手术治疗。在 4 个月的监测时间内，使用口内扫描仪获得了患者牙弓的三维模型。使用数字技术和数字卡尺，对 STL（标准三角语言）文件与从术前 CT（计算机断层扫描）中提取的 3D 模型进行叠加，对尖牙的萌出、暴露的腭侧和颊侧区域以及尖牙与切牙之间的距离进行了测量。
对传统和数字监测获得的数据进行了描述性和推断性统计分析，并对配对数据进行了 T 检验。
数字化监测具有许多优势，例如可以减少因在石膏模型上进行手动测量而导致的方法误差，以及可以比较同一患者在不同时间尖牙萌出的模式和数量。
