The E-Modeler
Representing the end of plaster models, the E-Modeler is a laser scanner capable of imaging impressions or models for permanent digital storage. The scanner creates 3D Models (E-Models) on the computer screen for full viewing and analytical capabilities. View E-Models from any angle, open them, close them, and make any measurement that is made on plaster models, only faster and more accurate.
The E-Modeler consists of both specialized hardware and software. The hardware consists of a laser scanning device using CCD (charge coupled device) arrays to map the terrain of the impression or model (similar to models used in manufacturing). A four-axis turntable with a manual fifth axis enables the scanner to access difficult areas within an impression. The computer system consists of a 200 MHz Pentium or Pentium Pro computer with 128 Megabytes of RAM, interface boards and software. The software is designed for orthodontic and oral-surgery using the Windows interface.
A simple click of the mouse begins the scanning process. In about five minutes the scan of the first impression is complete. Then the software prompts the user for the next impression. Lastly it prompts the user for the ‘clutch-plate’ which is an impression made for bite registration. The clutch-plate allows for occlusion calculation. Once the scans are complete the system builds a set of articulated ‘virtual’ models. The models are essentially perfect representations of the arches accurate within 6 microns.
The computer-based models will allow for diagnostic analysis and even set-up possibilities. No longer will extensive storage space be necessary as all patient models will be stored on the computer system or on removable storage devices. Hundreds of models could be stored on CD-Recordable or thousands on 1-Gigabyte JazTM disks.
The E-Modeler is a product of IRIS Development of Minnesota and is distributed by Ortho-Vision Technologies, Inc. which has offices in California and Minnesota.
At this time beta site selection is near completion. Orders for production models are expected as early as August 1997.
