The three important tissue groups in orthognathic surgery (facial soft tissues, facial skeleton and dentition) can be referred to as a triad. This triad plays a decisive role in planning orthognathic surgery. Technological developments have led to the development of different three-dimensional (3D) technologies such as multiplanar CT and MRI scanning, 3D photography modalities and surface scanning. An objective method to predict surgical and orthodontic outcome should be established based on the integration of structural (soft tissue envelope, facial skeleton and dentition) and photographic 3D images. None of the craniofacial imaging techniques can capture the complete triad with optimal quality. This can only be achieved by 'image fusion' of different imaging techniques to create a 3D virtual head that can display all triad elements. A systematic search of current literature on image fusion in the craniofacial area was performed. 15 articles were found describing 3D digital image fusion models of two or more different imaging techniques for orthodontics and orthognathic surgery. From these articles it is concluded, that image fusion and especially the 3D virtual head are accurate and realistic tools for documentation, analysis, treatment planning and long term follow up. This may provide an accurate and realistic prediction model.
正颌外科中的三个重要组织群（面部软组织、面部骨骼和牙列）可以被称为三联体。这个三联体在正颌手术的规划中起着决定性的作用。技术的发展导致了不同的三维（3D）技术的发展，如多平面 CT 和 MRI 扫描、3D 摄影方式和表面扫描。应该基于结构（软组织包络、面部骨骼和牙列）和摄影 3D 图像的整合，建立一种客观的方法来预测手术和正畸效果。没有任何一种颅面成像技术可以用最佳质量捕捉完整的三联体。这只能通过不同成像技术的“图像融合”来实现，创建一个可以显示所有三联体元素的 3D 虚拟头部。对颅面区域图像融合的当前文献进行了系统搜索。发现了 15 篇描述了两种或两种以上不同成像技术的 3D 数字图像融合模型，用于正畸和正颌外科。从这些文章中可以得出结论，图像融合，特别是 3D 虚拟头部，是用于记录、分析、治疗计划和长期随访的准确和现实的工具。这可能提供一个准确和现实的预测模型。
