3D功能模型在口腔正畸中的应用现状与研究进展

Application and research progress of 3D digital dental model in orthodontics

摘要:

在正畸临床工作中，牙颌模型是患者初始信息和疗程记录的良好载体，也是诊断分析的重要资料。在治疗过程中，可通过研究模型来了解当前的治疗情况及矫治进展，并及时调整治疗方案，达到最佳疗效。石膏模型存在固化时间长、边缘不清楚、取模变性等缺点，难以快速准确地测量数据并对治疗结果的预测存在一定的局限性。伴随着科学技术的不断发展，石膏模型已很难满足正畸医师的需求。3D功能模型技术的发展为数字化时代下的正畸治疗带来了巨大变化。3D功能模型技术广泛应用于数字化建档、三维诊断及治疗方案的辅助设计、正畸矫治、正畸材料设备制造、科研教学等。3D功能模型技术应用带动了口腔正畸的发展，该文就3D功能模型在口腔正畸领域的应用进行综述。

Abstract:

In clinical orthodontic practice, dental models are not only a great carrier of the patient's initial information and the treatment records, but also provide important data for diagnosis and analysis. During the treatment, these models could be used to reflect the current conditions and therefore contribute to optimizing the therapeutic regimen. Due to some disadvantages such as long setting time, blurred edges, and model deformation, plaster models are hardly efficient for measuring data and predicting treatment outcomes. With the continuous development of science and technology, plaster models cannot meet the needs of orthodontists any more. The 3D digital dental model technology has brought great changes to orthodontic treatment in the digital era. It is widely used in digital archiving, three-dimensional diagnosis and treatment design, orthodontic treatment, orthodontic material and equipment manufacturing, and scientific research and teaching, among other things. The application of 3D digital dental model technology has driven the development of orthodontics. This paper reviews the application of 3D digital dental models in the field of orthodontics.
