Mounting Upper and Lower Jaws for Obstructive Sleep Apnea Devices- Panthera
When scanning for an oral appliance with an intra-oral scanner, you can capture the upper jaw and the lower jaw and the Verical Dimension in protrusive, but if you don’t transfer that information to the lab, there is a good chance they will not properly mount them
There are a lot of software available to you where you can mount and pin the models together so when they are printed, they can use male and female components to align them properly
This video shows how to capture the upper jaw. It is the easier arch to scan as there is no tongue, saliva or a dark oro-pharynx to manage
Every type of user should watch this carefully and appreciate where we recommend you start scanning the lower arch. In our courses we go in to great detail on why you should not start in the anterior or the second molars. you instantly set yourself up for trouble. here’s the easiest place to start and to build and accurate model with
Also, as new user, if you are working alone, you can use the optragate to retract the lip and the tip of the camera to displace the tongue. We recommend that you use a focal setting of 12 mm’s. This may slow advanced users down, but for new users, it helps hide distractions for the camera and software and speed you along. If you look in the bottom right corner, anything in purple is what the camera ignores. There are certain elements you want the camera not to see so it doesn’t slow you down
quick little pointer for a new user that shows how to protect areas so that you don’t introduce errors like the tongue getting in your way. the blue models areas that are protected so any future data that lands on it is automatically deleted
Capturing the bite in open and protrusive position
With every 3D software, there are times where the data sets are too large for the software to recognize and merge models to. Once in a while, you may have to help in manual mode. In this case, you can see how the open bite prohibited the models from being articulated properly and we had to use the manual mode to pin the left and right bites

Digital Denture Duplication
Medit i500 was used to scan and duplicated a fractured denture. It was originally scanned in the patient’s mouth to capture the opposing and the bite and then submitted to the lab for fabrication
In this video we review with the instant replay feature of the medit i500 on how to scan a denture and not introduce double images or errors in the model. We first scan the occlusale surfaces of the denture intra-orally (this does not really matter as the software doesn’t know any differently), we then image the opposing, and then bite. We then remove the relined upper broken denture and continue the imaging to capture the intaglio

Mixing Photogrammetry and Intra-Orals Scanner by Medit i500
To date, the literature and research clearly points out that full arch scans with edentulous arches are prone to inaccuracies. That’s because we have never had a way to measure and verify models while scanning. There are two features unique to the Medit i500, namely the reliability map and the artificial intelligent implant suprastructure identification system. Individually, they do not provide much information with regards to accuracy, but if you understand how they work, you can utilize them to assess accuracy while you are scanning edentulous arches.
We proved the validity of this concept by utilizing these two features by incorporating a scan from the imetric Icam4D scanner and merging its data with the IOS to render a perfect match. Details are posted for our users in the Imaging Implants Section of our tutorial liabrary

Premolar Crown with Medit i500, Meditlink, exocad, Amber Mill Block, Coritec One by Imes Icore, and Millbox CAM Software
In this clinical case a patient lost a pre-existing crown. The remaining tooth structure had recurrent decay and a new crown was warranted.
After anesthesia was administered, the clearance from opposing dentition was assessed. The preparation was reduced to accommodate the necessary thickness of the material.
Once adequate clearance was achieved an Optragate was placed and an isolite was used to isolate the area. The preparation was scanned and then the lower arch was captured. The buccal bite was then taken to along the arches together
With Meditlink software, you have the option of designing the case yourself or sending it off to your partnered lab. The following video shows what happens to your case once the lab downloads the case
In this particular case, we designed our own crown and milled it with the coritec one milling machine
Once the amber lithium disilicate material was milled, its for was verified clinically. The crown was then crystallized and seated with NX3 resin cement

Using Photogrammetry to Validate the Accuracy of the Medit i500
Photogammetry has set the highest standard for full arch accuracy in digital dentistry for edentulous patients with multiple implant fixtures. An easy scan in under 15 seconds captures enough detail on scanbodies that help the software capture the location of the fixtures. Conversely, Intra-Oral Scanners (IOS) do not garner support for most of the literature that is currently published in dental journals. Scan paths can dictate the outcome of 3D model and determine how correctly it replicates the intra-oral condition. The same scan can render a variety of results and models based on the user and the direction the scans are taken. Simply stated, the user is control over the final product.
To use the ICam 4D scanner you must first calibrate the machine with a plate immediately prior to the intra-oral scan capture. There are specific reference points that the camera and software recognizes and after you capture about a dozen landmarks, you are ready for an intra-oral scan
Calibration of the ICam 4D Photogammetry Machine
After the camera is calibrated, the patient, or in this demonstration case, the model with Multi-Unit Abutment analogs is mounted with ICam Reference Bodies that are shaped like dominos. They can attach to the multiunit abutment or directly to the implant fixture (available soon in the USA).
The markers are captured by the device in the software with multiple identification marks, ideally 10 marks on each scan post. This data is then exported as an stl file that has all the locations of each cylinder preserved. This whole process just takes minutes. Most people just utilize this device for full arch impressions so they can bypass the verification jig for large cases. Here, we use it to assess the accuracy of the medit i500 ios to provide cross arch accuracy if doctors follow our protocols for imaging, which utilizes the reliability map as a guide for imaging. When then utilize the Artificial Intelligent Implant Suprastructure Identification Software to merge and evaluate the accuracy of the ios scan.
There are a lot of ways one can introduce errors into a full arch scan with any ios, but the medit’s powerful features that include the reliability map and the AI tool separate it from all other scans that do not allow you to assess the accuracy of your scan while you are imaging. You can only do so with the fabrication of a verification jig

Proper Retraction and Isolation Leads to Great Marginal Fit
In this clinical presentation, we demonstrate the removal of a crown that has recurrent decay. The bleeding tissue was managed with a double cord technique and expasyl and the margin was captured with the medit i500. The margin was also defined in the native imaging software which allows the user to visualize the detail before designing it or send it off to the lab. Once the case is transferred to cad software, the designed margins carry through and there is an opportunity to modify it

Comparing Milled and Designed Crown Margins
Have you ever compared the milled product with the designed restoration?
We scanned with the medit i500, designed with exocad and milled with coritec. after try-in, we scanned the restoration in the bluephase and then merged it with the design in exocad to see how well our material, or design, and our margins measured up against the proposal. we also documented the fit clinically and with radiographs. you can download the 3d models of the case and compared them yourself

Full Arch Scans With Multiple Variables
We scanned patient 4 different ways. HD and regular D and different filters and focal lengths. HD leaves the glitter free floating that scares new comers but builds nice models. really though if you retract everything well your imaging speed doesn’t change that much at all between filter 1 or 3. you can see how the mirror fogs up and slows me down just when i’m under patients nose. no big deal. just retract the lips and tongue and follow our imaging principles and you can take full arch scans in under a minute no problem
