Common questions
DEXIS IS 3800 questions answered
How much does the DEXIS IS 3800 cost in the UK?
From 360 Visualise the wired IS 3800 is £6,100 inc. VAT (RRP £7,609 + VAT) and the wireless IS 3800W is £8,100 inc. VAT (RRP £10,375 + VAT). These are Dentistry Show offer prices, valid until 30 October 2026. Both include IS ScanFlow 2.0, a 2-year manufacturer’s warranty, installation and training.
Should I buy the wired or the wireless IS 3800?
They scan the same way, with the same tips and software. Choose wired if the scanner stays in one surgery: it is lighter at 190 g, never needs charging and costs £2,000 less. Choose wireless if you move it between chairs and want no cable in the way.
Do I need to buy the notebook?
No. The scanner needs a high-spec Windows PC with a dedicated Nvidia graphics card. Our notebook is matched to it at £1,899 + VAT, so it works out of the box. If you already have a PC that meets the DEXIS specification, buy the scanner alone and we’ll check your PC before you order.
Is the IS 3800 an open system?
Yes. It exports STL, PLY and OBJ files, with direct exocad and DWOS output, so you can send scans to any lab, aligner provider or in-house printer that accepts those files.
IS 3800 or Imprevo?
The Imprevo is faster at 40 frames per second and has a deeper 25 mm depth of field. The IS 3800 is lighter, comes with three tip styles and costs less: £6,100 wired or £8,100 wireless, against £9,999, all including VAT.
What warranty does it come with?
A 2-year manufacturer’s warranty on the scanner, wired or wireless. Extended cover is available. Ask us for details.
Can I see it before I buy?
Yes. Book a demo at our scanning centre at Octagon House and try both models for yourself.
