简要总结
Patients with skeletal class III malocclusion were allocated to two groups. Both proximal and distal segments were repositioned using osteotomy/screw holes and plate locating surgical guides with pre-bent plates osteosynthesis in the intervention group, while manual free hand condylar segment seating was used for proximal segment positioning in the control group.
详细描述
Twenty patients with skeletal class III malocclusion were randomly allocated to two groups. Both proximal and distal segments were repositioned using osteotomy/screw holes and plate locating surgical guides with pre-bent plates osteosynthesis in the intervention group, while manual free hand condylar segment seating was used for proximal segment positioning in the control group. Accuracy of condylar position was assessed using computed tomography.
