唇腭裂新生儿的腭裂数字化模型方法

A new digital technique for cleft palate model in infants with cleft lip and palate

目的:利用硅橡胶印模和结构光三维扫描技术制取唇腭裂新生儿出生后第2天的腭裂表面形态数字化模型。方法:采用特殊重体硅橡胶印模材料制取患儿腭裂印模,通过3DSS扫描仪对石膏模型进行三维数据采集,经逆向工程软件处理数据,建立腭裂的数字化模型。结果:结构光扫描系统采得的腭裂数字化模型形态清晰,在软件平台上可以自由编辑和测量。结论:利用结构光三维扫描技术可以获取理想的新生儿腭裂数字化模型,该模型具有快捷、能长期存储等特点。

Objective： To fulfill one digital model of the cleft palate by the heavy silicon impression and structurelighted scanning technique. Methods： Impressions of cleft palate infants was taken clinically, which then was scanned by 3DSS scanner. With the reversed engineering software, the scanned data were reconstructed to a surface digital model. Results： The plaster model of cleft palate contained adequate anatomical details. The following acquired digital model could be viewed and measured from any direction by the software. Conclusion： The structurelighted scanning technique can be used as a ideal method for cleft palate infants＇ model, which have high precision and could be saved for long time.
