简要总结
- Preoperative CT.
- Virtual reduction of broken segments on software.
- Gain occlusion.
- Design surgical screw holes locating guide.
- Design the custom-made plates.
- Print the screw holes locating guide and the custom-made plate. under general anesthesia the parasymphseal fracture will be reduced using screw holes locating guide and the custom-made plates.
详细描述
Interventions 26 patients involved in this study will be divided in to two different groups, first group will be reduced using patient computer guided specific screw holes locating guide and custom-made plates.
Second group fractures will be reduced by conventional work flow.
Clinical evaluation:
A through medical and dental history followed by clinical examination was carried out for all patients. Clinical measurements were taken to ensure patient adherence to our initial inclusion criteria prior to further investigations.
A preoperative digital panoramic radiograph with 1:1 magnification was taken for each patient as a primary survey in order to exclude the presence of any lesion at the area of interest nor segment loss followed by A pre-operative CT.
