Hard Tissue Evaluation and Dental Relationship Assessment
- Pp. 43-65 (23)George Litsas
It is important to understand the aetiology of malocclusion so that orthodontic treatments can focus on the prevention of these conditions. Angle was the first to develop a simple dental relationship assessment based on the sagittal relationship between the upper and lower permanent molars. Since the introduction of cephalometric radiographs, hard tissue evaluation through cephalometric analysis has become an integral part of orthodontic treatment planning because it provides information such as the skeletal size, position, proportion and symmetry of the individual by which it is possible to assess skeletal disharmonies. The diagnosis of skeletal and dental relationships and their contributions to orthodontic treatment will be addressed in this chapter.
