New LiSi Disc:

CAD/CAM lithium disilicate based material as a disc.

Milling restorations from lithium disilicate more efficiently, cost effectively and conveniently this is now possible thanks to a new innovation on the dental CAD/CAM market. In collaboration with material specialist pritidenta, imes icore is the first milling machine manufacturer to launch a CAD/CAM disc in the material lithium disilicate. The new CORiTEC LiSi Disc is successfully validated for all current imes icore milling machines, which means that dental restorations made from lithium disilicate can now be produced by dentists, practice laborat ories and commercial laboratories more efficient ly and cost effective ly with imes icore machines.

The new glass disc is a highly aesthetic and innovative nano lithium disilicate CAD/CAM disc, available in 19 shades . The translucency of the material can be modified by heat. This means, that restorations milled from the same disc can be individually fired to achieve a higher or lower level of translucency without changing the properties of the restoration. The translucency can also be adjusted at a later stage through firing. In addition, the new material is compatible with a wide spectrum of conventional sta ins/glazes and veneering materials.

The new glass disc is suitable for the 98mm standard disc holder , it has a high edge stability and shows next to no chipping during wet sanding. A continuous milling procedure , in which up to 25 units can be milled in one sequence , means that these restorations can be produced at a competitive price. The workflows for all CORiTEC systems from imes icore have been adapted and validated. The combination of imes icore machines, tools and iCAM software guarantee safe processing and high quality results.

Dr. Batyr Kuliev from Nuremberg , has tested the new glass disc and produced restorations for two patient cases: one was a single crown and the other case was veneers. He was particularly impressed by the short milling time and the very good shade of the restorations. He feels the disc has a distinct advantage over the block in terms of efficiency when milling several different types of restoration all at once . An additional advantage to the block is the fact that it is possible to mill a 3 unit bridge from the disc.

The new glass disc will be available directly from pritidenta from November 2023. It has a height of 12mm and a strength of 450 MPa after complete crystallization. For the start, the following shades will be available: A1, A2, A3, A3.5, B2, C2, D2, Bleach 2.

A pipe dream? – A vision?


pritidenta presents a completely new zirconia product!

The new priti®multidisc ZrO2 multicolor Extra Translucent fills the gap in the dental zirconia portfolio. This advanced 4Y-TZP product from pritidenta really is a jack of all trades: 45% translucence and >1,150 MPa flexural strength combined in one round blank with integrated color gradient!

What makes priti®multidisc ZrO2 multicolor Extra Translucent unique is its balance between extra high translucence (45%) and optimal stability (>1,150 MPa).

This means the material can be recommended without reservation for flexible use across a particularly broad range of indications: It is suitable for inlays, onlays, veneers, and partial crowns as well as monolithic, fully anatomical, and partially or fully veneered crowns and bridges (up to 16 pontics).

It is also approved for custom anterior and posterior suprastructures on natural abutment teeth and implants.
This is what fans of all-ceramic restorations have been dreaming of!

Like every priti®multidisc ZrO2 multicolor the Extra Translucent variant has a harmonious color gradient that imitates that of natural teeth.

It is available in 7 multicolor shades and one bleach shade. Each color gradient covers a specific color range. The basic shade of the restoration is controlled precisely by its position on the round blank. This means all VITA shades can be reproduced with all the shades in between.

It’s as simple as “Sex on the Beach”!

Sounds rude? When you put your straw on the bottom of the glass for your first slurp, it tastes particularly sweet; further up, it gets more bitter. And just as you can control the taste when drinking cocktails, with priti®multidisc ZrO2 multicolor round blanks from pritidenta GmbH you can control the shade. Still sounds grotesque? Let pritidenta’s experts put it in slightly more technical terms.

priti®multidisc ZrO2 multicolor is available in seven shades that each cover a balanced color gradient. This means they can perfectly match the gradient of natural teeth in all 16 VITA classical shades. For example, the priti®multidisc ZrO2 round blank is available in “A light,” a composite shade that can achieve A1 to A3 shades. Positioning the restoration in the middle gives you an A2 shade. Positioning it higher up in the round blank makes it lighter and perfectly matches the A1 shade; putting it lower down matches an A3 shade. The positioning and color mapping can be adjusted to the right blank height depending on restoration height.

Coloring for ZrO2: Not just “pretty”, but smart too! – The new priti®multibloc ZrO2 multicolor High Translucent. Now pritidenta presents its tried and tested, German-made zirconia round blank in a block version as well: priti®multibloc ZrO2 multicolor High Translucent – easy to recognize from its magenta holder. All multicolor round blanks have the smart coloring that keeps inventories low whilst retaining the spectrum of shades you are used to.

Optional accessories

The priti®MPguide High Translucent allows you to match all multicolor shades to the VITA shade systems at a glance. The MulticolorPositioningTool software simulates the color gradient of the round blanks after sintering and projects the color effect onto the CAD restoration.
