计算机图像处理技术在前牙美学修复中的应用

目的探讨用计算机图像处理技术为患者制作美观的、符合个性特征的前牙修复体的过程。方法对13例需行前牙美学修复的患者拍摄修复治疗前及治疗中前牙图像，获取患者牙齿与周围软组织的美学信息，包括天然牙的形态、颜色、半透明度、个性特征，以及下颌息止位时和微笑时牙齿的切缘位置、龈缘位置等。分析美学信息资料后行美学修复设计，应用Photoshop 8.0软件制作修复预期效果图，指导技师制作修复体。结果完成13例患者的前牙美学修复，临床美学修复效果良好。结论将计算机图像处理技术应用于前牙美学修复设计，有助于医师和技师为患者制作美观的、符合个性特征的修复体。

Computerized image processing in esthetic rehabilitation of anterior teeth

Objective To investigate the application of computerized image processing in esthetic rehabilitation of anterior teeth. Methods Thirteen patients with esthetic problems in anterior teeth were included in this study. Oral digital images were obtained before and during treatment with a digital camera. All the oral esthetic data of the patients, including tooth shape, tooth shade, tooth characteristic color, incisal transparency, incisal curve, smile line, and gingival curve et al, were collected and analyzed. Diagnostic images of the anticipated esthetic outcome were created by computerized image processing software and transferred to the technician. Restorations were made according to the images by the technician. Results All anterior teeth of 13 patients were restored with this method and good esthetic results were achieved. Conclusions Computerized image processing is a useful method in the esthetic rehabilitation of anterior teeth.
