Lower First Molar Deep Margins Scanned by Shining AoralScan

In this video we demonstrate how the Aoralscan from Shinning 3D captures deep margins.

An old PFM crown warranted replacement due to open margins and recurrent decay. After the crown was removed, the margins were refined and the tissue was displaced with expasyl and retraction cord.

This video is deliberately captured slowly so a new user can appreciate how to hold the camera to capture the margins and the contacts of the adjacent teeth. You also have the opportunity to place your own margins and the path of draw before submit the case to the lab.

Where not to start with imaging with an intra-oral scanner

Most manufacturers recommend that you start your imaging at the second molar area, which is the least practical area to start with. The tongue and the lip and saliva are a quick distraction as the scanner does not know what you are trying to image. The incisal edges of lower anterior are also a tough place to start as the incisal translucency lets the light transmit through the enamel instead of reflecting to the cameras.

A good place to start is the second premolar first molar area where you can use the tip of the scanner to displace the tongue. Reducing the focal length to 12 mm’s allows the user to hide hard and soft tissue that can impede the rate of image capture. Watch the deliberate movement of the camera that helps the user manage the area to be captured with relative ease

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

digital denture set up

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

The final denture was hard relined and delivered to patient with minimal adjustments.

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

case set up for a simple premolar

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

Implant Margins Impressions Performed Extra-Orally With The Medit i500

Taking impressions, digital or analog way, was one of the greatest hassles in implant dentistry. we can now image the margins of the implant suprastrucure OUTSIDE the mouth, merge it with the intra-oral condition, and mark the margins on the digital file as opposed to getting hemostasis and tissue retraction in difficult situations..

medit i500 takes one of the most complex and error prone situations and simplifies it, whether you send the case to the lab or do in office restorations.

Proper Implant Placement and Digital Impressions with Scanbodies and Medit i500 Lead to Predictable Results

In this video, we show a recall of an implant restored with a scanbody. When the implant was initially placed, a scanbody was seated and an X-ray was taken to verify that it was seated. The titanium scanbody allows for visualization of seat. A peek scanbody does have a metal carrier but it is confusing to some users to verify that it is engaged with the fixture.

The proper placement of this biomax implant, followed by ideal contouring of tissue and bone around the head of the fixture, allowed for enough “running room” to create the desired emergence profile

Tissue Displacement Flash for Analog Impressions vs FLUSH for Digital Impression

With analog dental impressions, it is imparative to separate the gum tissue from tooth structure and to create a trough for flash for dye work. This is not the case with the intra-oral scanner by Medit. All you need to do is displace the tissue so you have a clear line of site to the margins, and you just need to be flush. You don’t need flash like you do with stone work

What Is An Implant Scanbody, Why Should You Use it, And Why You Need The Medit i500’s AI !

dental implant scanbody used by the medit i500

Dental implant surgery and restorations were the most risky procedures just 10 years ago. They were also the most profitable, but also carried the largest liability and the most significant surgical and restorative lab costs. A simple error introduced in the restorative process could easily eliminate the profit margin and a more significant mishap can create an undesirable outcome

We have seen dramatic changes in implant surgery where both the cost of the surgical stent and the fixture placement have reduced to the point where fully guided surgery is now the norm as they speed up the surgery and normalize the accuracy of placement across a broad range of practitioners with varying levels of experience. We are now seeing the same type of effect on the restorative side of the implant treatment, where digital dentistry is greatly reducing costs and errors.

With permission from blueskybio.com, we captured some key elements with analog impressions to highlight potential errors that can be introduced. The full video can be seen here:

analog impression of an implant fixture

The common sources of errors that someone can introduce are:

The inherent nature of impression material that can distort during the impression step
The angulation of the impression abutment may prevent it from seating all the way or may bind on the adjacent teeth making it difficult to capture an accurate impression
The size of the impression abutment can usually block access to the contours of the adjacent teeth where the pvs material does not capture the detail needed to generate good contacts and emergence profiles
Not securing the implant analog with the abutment in the impression material so that it does not distort or vibrate out of its position while pouring stone into the PVS material
With multiple implant, the problems can compound exponentially if the implants do not draw well together with complications ranging from locking the tray in the patient’s mouth accidentally or distorting the impression material enough when removing it where you decrease the accuracy. Some practitioners prefer to do this in multiple steps, correcting angulation and collisions with custom abutments and several impressions

Fortunately, in this impression of 3 implants that were placed with a guided, the impression abutments are parallel to each other but just a few degrees in either direction, you can have multiple collisions of the abutments with the adjacent teeth or in between the abutment themselves. What a scanbody does is it allows for the optical scan of a geometric shape that helps CAD software identify the exact location of an implant fixture, its timing, and its relationship to the arch form.

It has significant advantages as there is no distortion of the impression material. Moreover, you can capture all the detail of the adjacent teeth before you place the scanbody in the mouth. This dramatically reduces the errors and adjustments you will need to make during the seat appointment.

This video shows you the contour or the shape of a specific scanbdoy. There are many manufacturers that produce the scanbodies for a variety of fixtures with different geometries. Ideally, you use a titanium based one so that you can take an x-ray to make sure it is seated all the way. A frequent cause for error with digital impression is that you bind on tissue of bone which block you form seating all the way.

sample scanbody

Once you have scanned the pertinent information, you can then take the digital models to CAD software where the location of the fixture is identified digitally and you can design the restoration of your choice. This can be titanium abutment or a tibase that retrofits ceramic material like emax or zirconia. The following video demonstrates how you identify the scanbody in exocad and proceed with a sample design.

purpose of a scanbody

Once the design is completed, you can outsource the fabrication of the abutment and/or the crown. There are many machines that you can use to fabricate the titanium abutment. Please note that the milling machines do not mill the connection. The connection to the implant comes pre-manufactured. The cylindrical block is milled to shape. The cad software also maintains the relationship of the abutment to the crown so that they retrofit to each other.

Now imagine if you had multiple implants that did not draw together? What’s great about digital dentistry and how we use the Medit i500 here is how we utilize a single scanbody to capture the location of 3 fixtures. One thing we emphasize at CAD-Ray is how digital impression allow you to create models over time and out of sequence. They are also editable and additive. In the subsequent video we demonstrate how you can capture segments at a time, which can greatly help when you have implant abutments colliding into each other.

You can place the scanbdoy in one location, scan it, digitally protect the area, remove the scanbody, place it into another location and image it at the new location, dramatically overcoming all the obstacles described above

3 implant fixtures captured with one scanbody

Now for the greatest news and the largest advancement in digital dentistry in a decade! Medit i500 has launched the Artificial Intelligent Implant Identification System where the software automatically recognizes these scanbody and lets you skip dozens of steps to get to the immediate design steps of the restoration. The algorithm utilized to match the digital scanbody to the physical one is proprietary to Medit and is unparalleled in its accuracy. A lot of the guess work and inherent errors in the digital platforms are reduced with this software which is a contrasting as the difference between analog and digital impressions.

You Need Enough Redundant Data Between The Pre-op and Prep Models To Activate Image Aquisition

When you have preops that you are trying to stitch to preps in medit, and this could also include relating scanbodies to arches as well, you need enough data that is redundant in both catalog boxes

if you watch this video carefully, you can see how i over trimmed the mesial part of the equation and even though the camera is active, it is not acquiring images. you can see the red box.
once i move the camera to the distal molar, the acquisition starts because the molar has more data points than the premolar and the software / camera recognized the area and started to acquire images.
understanding this will unlock a lot of complicated cases and make the easier for you
