Full Digital Dentures

What are Digital Dentures

Digital dentures are a new concept that have come onto the market and now challenge how conventional dentures are made. Digital dentures are made from a high quality PMMA material that is 8 times harder than conventional dentures. They are designed using 3Shape Cad Cam software and milled on our state of the art PM7 Ivoclar 5 axis milling machine, for the first time ever we can offer our patients unparalleled accuracy and precision.

Latest Technology & Methods

Digital compared to conventional

We have made both digital and conventional analog dentures and inserted them. In my experience I believe the proof is in the satisfaction of the patient when they walk out the door.
Patient feedback is comfort of the new denture is a lot better than previous sets made.
Outlined below are the areas being questioned and answered as best as I can from our experience and others who are manufacturing digital dentures worldwide.

They’re more predictable

As digital dentures are CAD/CAM designed, it takes out the guess work of where to place the teeth. We are able to place the teeth exactly where it naturally was. As it is all on digital file, we can replicate this time and time again. Even when a new impression is needed, we can use the previous design that the patient was happy with and give them the same looking denture by a few clicks of a button. Even if the patient has lost their denture, we are able to mill out a new exact copy of the denture they lost.

They are far more comfortable

We are fully trained in SEMCD techniques to gain suction on complete lower dentures. The main problem with dentures is being uncomfortable is that they move around in the patient’s mouth. The impression techniques have improved the fit of the denture along with the accuracies of the PM7 mill. PMMA that is used for the dentures does not absorb liquid which helps it being cleaner in the patients mouth as it won’t stain or smell. The comfort is improved also from being CAD/CAM designed. We are placing teeth where they naturally would be without guessing. Analog way you have wax in the way. Digital there is no wax and we can see ridges in the design to know exactly where to place the denture tooth.

Improved fit​

Due to the improvements in technology and the materials the accuracies of the prosthesis is improved. No shrinkages of the plaster models, no shrinking of acrylic during processing. The impression is scanned straight into digital form and the Ivoclar PM7 mill will mill the denture out of a PMMA disc that has no shrinkage. Resulting in a tighter fitting denture.

There’s less appointments​

Using the BPS system, we are able to cut out one appointment as the 2nd stage of manufacturing the denture is combined with the 3rd appointment. Another technique we can use is the reference denture which allows us to go from an impression straight to a hard try in of teeth. No need to have registration appointments which saves time and there for less appointments

Less adjustments​

The accuracies of digital, the comfort, improved fit, the impression techniques, CAD/CAM designed, all results in the end product not needing to be adjusted as much. Dentures will still need to be adjusted when there are sharp bits of bone, thin oral mucosa and the hard denture sitting on top. But due to being able to have a hard try in replica of the finished denture we are able to see in confidence if the bites incorrect, tooth position, suction and movement, unlike analog denture try ins made in wax.
