One of the most challenging designs to do chairside is the design of a multi unit temporary that needs to be printed. This is incredibly time consuming as you spent significant amount of time just marking margins on a dozen units.  With this technique pioneered by CAD-Ray you can bypass the margination step and design a large case in about a minute.

The clash of the titans are in full effect.  We are not smart enough to understand all the dynamics of patented software and hardware. While we let the manufacturers sort it out, we wanted to demonstrate how the new mandibular jaw movements are captured in Meditlink

Many scanners limit the number of scans you can take on a patient.  This becomes cumbersome when you want to image pre-existing conditions, tissue scans for implantology, and other advanced needs

With version 3.0 in Meditlink software, launched in October of 2022, you can import or scan multiple models in the same patient chart

There is a concept in digital dentistry that is called “mixing good and bad data”.  What you have to appreciate is that two different objects can’t occupy the same space in the same 3D model.  The clinical example of this is when you pack 2 cords, image the margins, then remove the top cord and image the preparation some more.

This introduces a lot of errors and distortion at the margins. You either have to image with 2 cords retracting the tissue at once o

In this presentation we detail the implant suprastructure identification system where an existing abutment is removed and scanned extra-orally to capture the margins readily after the abutment is anodized.

In April of 2022, Medit launched its wireless version of the i700 intra-oral scanner. We’ve been testing it ever since and are impressed with the range that it has. You want to be within 10 meters but more importantly you want to have clear line of site from the scanner to the hub. Much like anything else that is wireless, the further you are from the receiver the more difficult it is to maintain connection. In this video we demonstrate the distance at which you can maintain good connec

Medit Compare, now called Medit Design, now has a boolean cut feature that lets you extract a temporary shell model from wax up or mock up model and prep model for easy and quick designs without painful margin marking on multiple units.

Until recently, when you submitted a case to Panthera Dental for a Obstructive Sleep Apnea Device, they would manufacture it and send it to one of their partner labs. This would delay the process and add other hurdles. You can now directly submit the cases through the meditlink portal. You must attach an Rx form and you must have an account with them.

It is a good idea to attach support pins to your models so labs don’t lose the vertical dimension and the protrusive position you captured

Medit’s software allows you to remove and pre-existing abutment and scan it outside the mouth. This allows you to find your margins without ever having to displace the tissue or reach hemostasis. Important matters to keep in mind with workflow

You must fill out the Rx form correctly and identify the abutment location
You must take the abutment scan at first in the right catalog box (upper jaw or lower jaw)
You must take the tibase / abutment outside the mouth and scan
