This is an advanced milling unit that is designed for use in dental laboratories. We needed another milling unit to back up our ageing CEREC MCXL unit so that’s why I chose the MC X5.
What’s good about it
With this milling unit, you can make pretty much anything including full dentures, part dentures, implant guides, occlusal splints, crowns and bridges. It’s been a great addition to our practice as it enables us to make a new set of dentures within 24 hours. However, it’s not for everyone; you have to enjoy doing laboratory work.
Primescan is the latest CEREC scanner and it works beautifully with this unit. I recently had a couple of patients with severely decayed and broken teeth. A single scan of their teeth was converted immediately into dentures. It’s a very efficient system. The digital workflow accuracy is superior to traditional analogue methods.
The MC X5 can operate with a huge variety of materials. It mills from pucks about 10 centimetres across by up to 35 millimetres thick. They can consist of multilayered, multicoloured PMMA so it looks like graduations in a tooth from light to dark. They can be coloured pink for denture bases. They can be any type of zirconia for crowns, metal (needs sintering after milling) or even an ivory wax material that we use for trial dentures. Most CADCAM blocks are millable too. The newest blocks are titanium with a pre-machined abutment interface for a variety of implant systems.
It’s delivered with inLab software that gives you the ability to design virtually any dental appliance.
What’s not so good
It’s really loud when milling PMMA. It sounds like fighting cats. It also needs a decent sized compressor, though similar to a normal compressor for a dental practice.
