AS 260
AS 260
AS 260 is the latest intraoral scanner model designed and manufactured by Alliedstar™ that features a user-oriented scanning experience which allows for easy and precise re- construction of deeper objects and interproximal areas while further simplifying the setup process by enabling single USB cable connection.
A major advancement that sets AS 260 apart from previous Alliedstar™ models is a full-scale upgrade towards the optical structure, which has completely lifted the depth of field to another level and improved much of the data quality with better fidelity and a solid accuracy.
Designed with a mindset centering users’ day-to-day need, AS 260 minimalizes the workflow from start to finish with its every feature crafted for intuitive operation and streamlined use in actual dental practice. The realization of remote control liberates practitioners from having to touch the keyboard/screen to move on with the process, while the light-weight body (175g) and duo button design release much of the burden on users to ensure a comfortable experience even during long-time use.
Being automatically adaptive to different scenarios, the device distinguishes itself by having its algorithms built around realistic intraoral settings so that the need for manual adjustment and retakes has been minimized when AS 260 is used across various kinds of cases. That said, when employed for intraoral scanning, the model does not require a seasoned specialist for a successful scan – it is designed to provide a smooth digitalized workflow for all users, despite their levels of adeptness.
Adopting a software platform called AS Connect developed by the same manufacturer, the Alliedstar™ portfolio is able to offer a feature-rich ecology for different dental care services including tooth implant, restoration and orthodontics. With AS Connect, users are empowered to quickly access and conveniently manage cases stored in the platform, the compatibility of which allows for the export of multiple formats so that a seamless integration with third-party applications like CAD/CAM in subsequent procedures is made possible. Cloud storage is also available for frequent revisits via other devices.
As a calibration-free intraoral scanner, AS 260 eliminates the hassle of keeping an extra piece of calibration equipment in the toolkit, removing unnecessary time and efforts to maximize the work efficiency for den- tal practitioners. Alliedstar believes the future of digital dentistry pivots around accessibility, ease of use and convenience. To better match a modern dental clinic that emphasizes a comfortable and stress-free patient experience, AS 260 comes with a replaceable cable to contribute to a truly clean and tidy environment with less of a clutter of wires and cords.
Digital dentistry presents practitioners with a chance to step up the overall quality of their diagnosis and treatment. Display of an illustrative and convincing reconstruction of their intraoral environment assists dentists in building an efficient conversation with the patients. With the digitalizing trend continuously surging on a global scale, it is undeniable that a digital dental workflow reveals an opportunity to benefit both the industry and people seeking a trust-worthy treatment solution.
NOTES
*Accuracy Test Methods
For evaluation of the accuracy, two aspects (trueness and precision) were tested respectively employing methods commonly adopted by the industry.
A gypsum dental model was scanned beforehand by an industrial grade scanner to generate a dataset as reference for trueness testing where a single, trained operator used AS 260 to scan the same model for 10 separate times to obtain datasets (all STL formatted).
The datasets were then superimposed to the reference dataset for 3D comparisons to acquire 10 average error values, the mean of which was calculated to describe the trueness.
In terms of precision measurement, pairwise comparisons between the 10 datasets were operated and the average error of each comparison was calculated to generate 45 different values, the mean of which was then used to represent precision.
