I specifically purchased this unit for my implant work. When Manuel Netto, the rep from Sirona, told me it can be used for a lot more than just implants, I thought he was doing the ‘hard sell’. But I was wrong. The Orthophos XG 3D made me realise that as dentists we have been practising in the dark ages. People’s mouths are three-dimensional and you need to view it in three dimensions. This unit has applications for periodontics, root canal therapy, bones—everything.
What’s good about it
It takes 15 seconds to scan and then four-to-five minutes to process the data. It maps out about 500 slices in three axes of direction—top down, front to back and sideways. Each scan is about 500mb in size which results in a very clear, very detailed scan. It’s possible to move your POV down through the image while changing the angulation.
So far, 100 per cent of patients have been impressed by this unit. Even the most scared patient who normally refuses treatment become easy to convince once they see their results manipulated in three dimensions. One patient saw her scan and thought she had a bullet hole in her mouth. It was actually an abscess for which she had been refusing treatment for months. Seeing a 3D visual representation of the problem changed her mind immediately.
I believe that 3D scanning should be considered the standard of care within the next 10 years. This machine works wonders.
What’s not so good
The cost but there’s not much you can do about that.
If metal is present in the mouth, it scatters the beam and results in artifacts. However, recent software has gone a long way in minimising that effect.
