What is ISO 20896-1 - Dentistry digital impression devices about?
ISO 20896 discusses digital impression devices for dentistry. ISO 20896-1 is an international standard that provides for assessing the accuracy of digital impression devices.
ISO 20896-1 is the first part of a multi-part series that lays out test methods and procedures for assessing the accuracy of a three-dimensional numerical description of intra-oral surfaces acquired directly from a patient with a hand-held scanning device.
Note 1: The test methods under ISO 12836 do not apply to ultrasonic, radiographic, or magnetic resonance imaging methods.
Note 2: ISO 12836 specifies the test methods for the assessment of the accuracy of digitizing devices that use a fixed or mechanically guided scanning device.
Who is ISO 20896-1 - Dentistry digital impression devices for?
ISO 20896-1 on digital impression devices for dentistry is useful for:
- Manufacturers of digital impression devices for dentistry
- Test centers for medical device
- Dentists
Why should you use ISO 20896-1 - Dentistry digital impression devices?
Dental CAD/CAM systems produce indirect dental restorations that require a three-dimensional digitized description, often called a digital impression, of a patient's dentition as a starting point for the design and fabrication of inlays, crowns, bridges, and larger fixed or removable appliances.
ISO 20896-1 guideline assists you with requirements on reference measurement of test objects and test methods such as measurement of reference values, ambient conditions, scanning pattern, number of scans, processing of the digital impression, assessment of accuracy, and test reports for digital impression devices.
ISO 20896-1 provides best practice guidance on digital impression devices that digitize the three-dimensional surface that is sufficiently accurate to enable the design and manufacture of a clinically acceptable restoration.
Thus, ISO 20896-1 improves the performance of digital impression devices and ensures the data collected is reliable.
