Three-dimensional interpretation of periodontal lesions and remodeling during orthodontic treatment. Part III.

摘要: In a clinical study of 11 adult patients, HR-CT-examinations were performed before or during and after orthodontic treatment with fixed appliances. The period between the first second CT-scanning varied from 12 to 24 months. Comparison CT-examination permits three-dimensional evaluation osteoclastic osteoblastic alveolar remodeling. incidence periodontal lesions such as bone dehiscences, fenestrations root resorptions was assessed in relation initial situation concept. Anatomical risks small process, thin buccal lingual plates, eccentric position teeth, basally extended maxillary sinus progressive loss. Therapeutic uncontrolled sagittal vertical movements incisors cortical intermaxillary anchorage preparation. process HR-CT allows interpretation osteodynamics, especially development repair orthodontically induced dehiscences tooth movement.
