In this video we demonstrate some of the most common problems associated with second molar impressions. Usually the distal margins can be blurred by the presence of hemorrhaging or soft tissue. In this particular case, we use the tip of the camera to displace the tissue and digitall correct an area for better accuracy. The isolite systemisolite systemisolite system does a great job controlling the tongue and the lips and with proper retraction you can image a quadrant in very little time

The second most commong problem is a change in the vertical dimension before and after we prepare the last vertical stop in the arch. We advocate that you take two bites; one before preparing the distal extension and one after you prepare it. Comparing the two buccal bites will let you know if you will have issue with your vertical dimension and allow you to reduce the post op adjustments

With digital dentistry and designing cases in color, you do not need flash like you do for analog impressions.  The purpose of flash is so that you can discern the separation of the margin from the tissue in stone.  You still need to displace the tissue to expose the line of sight to your margins, but you don’t necessarily need the flash. But if you get both, it certainly helps!  You can see an example of this with the margins scanned in HD mode with the Medit i500.

In the following video we demonstrate how we set up the case and image the prep.  With digital dentistry, you can image the opposing, the arch, and the bite in any sequence you want. This has great implications clinically where team members can scan most of the data needed and the dentist can step, prepare the tooth, and just image the prep and the contacts of the neighboring teeth. Advanced users who are looking for speed can process the case even before the prep is imaged, and then just image the prep and only process that arch and merge them in the cad software, greatly speeding up the process

This first video details how you can mark your margins in meditlink with your medit iscan software.  The very first step that you must do is properly identify the job definition.  If you choose orthodontic modules or bite splints for example, you will not have the opportunity to transfer the marked margins because they are not part of the equation.  So the best practice is to always properly label the tooth and the prescription

Once you have processed the case and it is in the preview mode you have one last chance to review the order and submit it to your lab of choice.  In this next video we show what happens to your data once your lab receives it and particularly how your drawn margin line accompanies the upper and lower arches and the prepared upper right molar

A common question we get at cad-ray.com is how a case cannot be submitted to a lab.  Most of the time, it is because the job has not been created.  You must identify the teeth or the arches that you will be working on define the restorative material of choice or the type of appliance you will be submitting.  Once you have done so, the order box will appear for you to submit the case

In this next video, you can see what happens when a lab gets your case and what they can do with it

In this article we demonstrate how two separate implants are placed with guided surgery and then scanbodies are used immediately after placement to capture the location of the fixtures. While the patient is healing for the next 4-5 months, an upper tibase restoration will be fabricated with a lower custom titanium abutment.  Digital impressions were taken with the Medit i500 for implant planning and Blueskybio software was used for the two surgical stents.  Two 4.3 mm biomax implants were placed

To start the case, the job is defined for an upper tibase and a lower implant restoration.  Proper labeling here is important so that the cad software, exocad, can launch the appropriate design components

While the patient was anesthetized, the edentulous arches on the patient’s left side were imaged.  The bite was also taken, which ignores any information that is present in the scanbody catalogs.  It is important to understand this as a new user because usually, the scanbodies are taller than the occlusal heights of the adjacent teeth. If these were captured in the wrong catalog boxes, the upper and lower jaw alignment could be mal-aligned

After sufficient anesthesia is achieved, the two surgical stents were seated and verified for fit.  It is up to the clinician’s discretion to either lay a flap to access the area or to do the surgery flapless.  Since the implant designs showed ample bone, and the fixtures were going to be placed sub-crestal, a tissue punch technique was used here as the area will granulate in.  At uncovery, a flap can be used to advance the tissue to the buccal to enhance keratinized tissue appearance

One of the greatest benefits of digital dentistry is that you can capture parts of a model independent of time and sequence.  In this particular situation, we opted to capture the scanbody for the upper arch even before the lower arch received the implant.

We utilized Medit i500’s Artificial Intelligence to spot and mark the scanbodies.  Once these data points are plotted and synchronize with what appears intra-oral, you no longer have to worry about distortion or artifact in the scanbody itself.  Color coding is a good indication of an accurate identification of the DESS scanbodies.

The significance of these identified scanbodies is that you can directly import them into the cad software and the fixture locations are readily identified and the design process can proceed.
