Digitizing, storage and analysis of 3D Dental Models. The dental cast is the traditional three-dimensional (3D) patient record for measuring linear changes in the dental arch. However, plaster model analysis for this purpose does not provide important information such as structural and volumetric changes in the palate or 3D measurements of orthodontic tooth movement.
The use of 3D scanners to determine the surface contour of objects by optical methods has become important in scanning of dental structures to create a 3D model and to assess the dental arch form and jaw morphology parameters.Replacement of plaster orthodontic models with 3D computerized images can benefit in accuracy, efficiency, and ease of measurement of tooth and arch sizes. We present several applications of 3D digital dental models.
Saving money on the monthly cost of storage space needed for the traditional plaster models
Digitized 3D models can be stored on computer disk in STL format file. For quality evaluation of our models you can download this 3D model sample and viewer software for Windows or Mac OS X 10.5 OS. The file size depends on size of dental arch and can be from 5 MB to 25 MB. So, you can store up to 900 models on one standard DVD disk and save a space for storage.
The ability to send virtual images anywhere in the world for instant referral or consultation as needed or for studies purposes
Digitized 3D models in a moment can be send anywhere in the world for instant referral or consultations, for studies or scientific purpose. Referrals, reports or patient records in which 3D digital models of dental cast, x-ray images intraoral and extraoral photos, cefalometrical analysis data and other information, can be stored in digital form, So, you can effortlessly manage patient records.
Model restoration
An important application of 3D models should be in the restoration of plaster dental models. Using special software the plaster cast defects or broken fragments of teeth can be restored. We can produce a copy of dental model using high accuracy 3D printing technology (the average difference between original model and copy will be less than 0.1 mm) Company “ELINVISION” cena produce a high quality model from Your old dental model from plaster or ABSPlus plastic.
Measurement of Dental arches
A high accuracy 3D dental scanner VAS-38 could automatically measure dental arches by scanning dental casts. System software uses acquired data for measurement of dental arches, to store dental cast models in 3D databases, to use model data for design of appliances. This system is useful objective tool for medical tasks solution and in orthodontic patients care.

Approximation of dental arch curvature
3D models can be used for evaluation of dental arch form and approximation of dental arch curvature by mathematical functions for treatment outcome planning. The dental casts of 15 subjects were scanned and measured to test the reliability of method. 3D database from digital models is useful tool for analysis of developmental changes, diagnosis and treatment planning.
