Description

建立模型的方法
技术领域
本发明涉及一种证实在表面上的处理效果的方法。
背景技术
WO 14041186A1描述了一种系统或组件，例如身体的3D建立模型的软件。
消费者意识到衰老和特定的进攻性美容处理可能对他们的身体表面或财产造成损害。特别是在个人护理中，尽管可以采取补救措施来减轻这些有害影响，但这个概念对于消费者来说可能难以掌握，并且补救处理的全部效果难以充分理解。
发明内容
本发明涉及一种证实在表面上的处理效果的方法，该方法包括如下步骤：
i.任选地，使至少一个未处理的表面成像，
ii.将至少一种处理施加于所述表面，使得如果不进行步骤i)，则用不同的处理来处理至少两个不同的表面，
iii.使所述表面成像，以形成图像，
iv.将成像数据转换成适合在3D打印机上生成放大的图像的格式，
v.制得成像表面的放大的3D模型。
在本发明的上下文中，术语“未处理的表面”是指在两小时内没有用会破坏表面的产品进行处理的表面。
在本发明的一个实施方式中，图像是拓扑表面图像；优选地，拓扑表面图像是利用激光轮廓仪来生成的。
拓扑表面被转换成适合3D打印机的格式，优选地，被导出到作为描述拓扑(3D)表面的每个点的空间坐标(X，Y，Z)的数字文件中。优选地，这通过轮廓仪来完成。合适的轮廓仪的一个实例是Sensofar S neox轮廓仪，其可以生成待研究的表面的3d图像。轮廓仪软件，例如sensoSCAN v5，可以导出“.dat”文件，该文件列出了每个点的所有X，Y，Z坐标。
优选地，成像数据的转换iv)包括放大处理。优选通过改变分辨率、坐标轴的单位和/或重新定标来实现放大，从而生成具有新的空间坐标的新的数字文件。一种优选的放大数据点的方式是使用Matlab。在这个优选的方法中，“.dat”文件作为矩阵导入到Matlab中，并且使用一组Matlab脚本来运行该矩阵并改变分辨率/比例。非常优选的是将矩阵导出到新的ASCII文件“.XYZ”中，该文件列出了每个点的所有X，Y，Z坐标。
将成像数据转换成适合于3D打印机的图像。优选地，该文件被导入到3D-CAD软件中，并将3D表面应用于平行四边形的面上以获得3D对象。所得到的3D图像被导出到与3D打印机设备软件兼容的数字文件。XYZ文件优选导入到“Rhino”软件包中，该软件包可以将XYZ文件转换为3d文件，并导出为.STL文件。
打印3D图像以形成3d对象。这可以通过使用EOS(电光系统)EOSINT P380选择性激光烧结打印机和生成的放大表面的3D复制品来实现。
优选地，待成像的表面是人体的一部分，更优选的是皮肤或牙齿。
最优选地，该表面是牙釉质。这是由于消费者在认识釉质腐蚀方面以及某些处理可能产生的有益效果上存在困难。该方法特别有利于证实牙齿表面上羟基磷灰石的形成。WO2008/068149，WO2011/110414和WO2011/160996中描述了合适的羟基磷灰石的生成方法。
在本发明的一个方面，将未处理的表面与处理过的表面进行比较。
在本发明的第二方面，比较使用两种不同的处理产品进行处理的表面。
在本发明进一步的实施方式中，多于一种处理被施加于表面，优选地施加于釉质。这可以是两步方法来处理表面的一部分，或者可以显示两种替代处理的不同效果，从而可以将不同的处理应用于釉质的不同区域或不同的釉质样品。
后一种方法可用于显示使用不同摩擦值(abrasivity)的牙膏来刷牙齿矿物质(例如牙釉或牙本质)的影响。
现在将通过以下非限制性实施例来说明本发明：
实施例
通过使用金刚石磨轮将人提取的门齿和前臼齿的根除去。然后通过高耐磨性盘(Tycet Ltd，Hemel Hempstead，Herts，UK)使面部表面变平，直到其平坦到足以装配大约50：50的大小为4×4mm的牙釉质和牙本质块。然后用Two Well Model 3242Wire Cutter(Ebner，LeLocle，Switzerland)切割牙齿的舌部，留下约2.5mm厚的切片。样本是平面平行制备的。然后将表面依次用3μm和1μm金刚石悬浮液(Kemet International Ltd，Maidstone，Kent，UK)进行抛光，并用0.3μm Micropolish II(Buehler，Coventry，UK)进行最终抛光。然后将样本超声处理5分钟，用Milli Q水(Millipore，UK)冲洗，然后再次超声处理5分钟以除去在抛光过程中形成的任何玷污层。
未处理的样本根据下列方法成像。
将样本安装在装有平纹益处牙刷的改良的马丁代尔刷洗机(Goodbrand-JeffreysLtd.，Stockport，UK)上。在这个装置中，刷头展现Lissajous图形，它们结合了线性和椭圆运动，以确保已刷洗样本的全面覆盖。来自图像的牙釉质样本用已知摩擦值的牙膏的浆液进行刷洗。将牙膏与水和0.5％w/w羧甲基纤维素钠(SCMC)溶液以1：1：1的浆料：水：SCMC的比例进行预混合。将牙膏浆液(10ml)加入到刷洗机的孔中，并且以275g的施加负荷以150循环/分钟刷洗釉质-本质样本2×10分钟。模型的图像是从样本的釉面照取的。
成像方法
通过使用带有Sensofar S neox轮廓仪的SensoSCAN v5将拓扑表面导出到数字文件中作为描述拓扑(3D)表面的每个点的空间坐标(X，Y，Z)，将拓扑表面转换为适合3D打印机的格式。
通过导入到Matlab作为矩阵并使用Matlab脚本来运行该矩阵并改变分辨率/比例，来放大所得到的数字文件数据。然后将矩阵导出到新的ASCII文件“.XYZ”中，该文件列出了每个点的所有X，Y，Z坐标。
使用3D-CAD软件将成像数据转换成适合3D打印机的图像，并且将3D表面应用于平行四边形的面上以获得3D对象。所得到的3D图像通过使用“Rhino”软件包导出到与3D打印机设备软件兼容的数字文件，该软件包可以将其转换为3d文件并以.STL文件的形式导出。
打印3D图像以形成3d对象。这可以通过使用EOS(电光系统)EOSINT P380选择性激光烧结打印机和生成的放大表面的3D复制品来实现。
比较两个3D图像证实牙膏对牙釉质的影响。
