The Digital 3D Shade Guide

3d-shade-guide-instructions

We’ve digitized the Vita 3D shade guide to help with color identification.  The same Medit scanner was used to scan the tabs and then this digital file was created. the assumption is that the same camera and light will hit natural dentition and the net effect will be the same.  Use at your own risk.

i think this can work!

i scanned the vita 3d shade guide with the same light i would use to scan teeth. Start with matching the value, then the hue, and then chroma.

Measuring Intra-Oral Scanner Accuracy and How Accurate is the Medit Scanner?

Still not a single article published that says Medit ios is a good scanner ! its just been user driven for 3 years now.

 

it’s a good thing, because the world just changed. it is irresponsible to extrapolate research done outside the mouth on stone models or impressions into clinical significance with intra-oral scanning. There are parameters that are impossible to quantify like focal distance throughout the scan (unlike desktop scanners with known focal distances), the codes use to do the algorithms, the scan patterns, and also how light is treated by enamel, dentin, and restored materials.

 

i can’t believe people still use terms like trueness and accuracy when they really don’t even exist when you scan intra-orally. Like analog impressions, it is impossible to judge digital impression accuracy LIVE while it is happening.

 

Enter Medit! There are a few distinct ways to demonstrate an accurate scan live while it is happening. One way is to import a geometric shape that doesn’t alter its form while models are being rendered. That’s what’s demonstrated here. To my knowledge no one has ever studied this approach because no other camera lets you do this. i did see some publications where the authors attached objects like radiographic markers and after it was processed, they could measure that object and see if it distorted or not, but nothing at this level.

Preview of Medit Compare Used in Merging Models, Modifying Them, Inverting Them, and Relating Them to Each Other with Medit Compare

This case shows how to relate models to each and maintain their relationships. It features the power of the Medit Compare app that lets you duplicate models, trim them, modify them to your liking. There are some very useful features in this app that can come in very handy
an important matter to remember is the “direction of travel” which is taking models from the Target folder and moving it to relate it to the Reference folder.
All models placed in each folder will maintain their relationships to each other when traveling to connect with the other models. Inverting models will also come in handy for advanced users. You can see the full video and download the case and design along here
