Working with Laura at cad-ray made all of my concerns go away. She was there to help me with my Exocad software installation, even outside of normal business hours - really hard to come by! I also purchased a Medit i500 and getting that setup and working in my clinic was seamless. I could not have asked for better support while navigating digital dentistry.

They helped me find the perfect intraoral scanner to suit my needs. Not too much or too little, and a great price. Every time we have a technical question, a sharp human answers the phone, troubleshoots, and remotes in when needed-- navigating MS updates and graphics card issues. My i500 died this week. They overnighted me a trade-in at a totally reasonable price, and even shipped me a laptop to drive the i600 while I got a new one (they knew my 2020 laptop wouldn't keep up!).

About two weeks after the order was placed, they called me up and said, “VHF just got an exclusive with “The Big Boys” so they are cutting ties with all the little independent distributors. They just called us, and we just found out. What this means is that we won’t be able to provide you service after purchasing the VHF mill that you just bought.”Now, they could have just left it at that. They could have said, “Sorry, it’s out of our hands.” They could have said, “We appreciate your business, but it’s not our fault.” They could have said, “That’s the way the cookie crumbles.”But they didn’t.Frank Weinstein calls me up and tells me that they want to make this right, so they are going to hook me up with a brand new Imes Coritec One+ for the same price as the VHF. The Coritec One+ is like the Mercedes of mills for in-office. This is the new model that just barely came out. It is a 5 axis mill. It does wet and dry milling. It does blocks and pucks. It mills all materials know to man, including Vibranium. It can also fly the space shuttle, and make all your wishes and dreams come true. It’s that good. It came with the laptop, Exocad, all the tools, and all the bells and whistles. It came fully loaded. It came white glove delivered to my office. It came with in office training. It came with the extra bur package. It came with everything and the kitchen sink.So, I paid 36k for a mill, and because of something that was not Cad-Rays fault, they ended up giving me a 60k mill for the same price.In the words of the great Tony Stark: “That’s how Dad did it. That’s how Cad-Ray does it. And it’s worked out pretty well so far.”Thank you Frank Weinstein and Armen Mirzayan for having outstanding customer service and going the extra mile every time.read less - 4/09/2021

In this article, we demonstrate how to manage a crown replacement on a second upper premolar with the Medit i500, exocad, and the imes icore CORiTEC ONE milling machine. The pre-existing crown was over 2 decades old and the recession revealed a supra-gingival margin. Furthermore, there was no room to improve the anatomy or its outline form as it was in occlusion with the opposing dentition.
A powerful design technique is the copy of the pre-existing crown. Images of the pre-op are taken while the patient is numb and its contours are copied onto the final design of the restoration. This process usually takes a minute or so, after which we milled a size 12 emax block restoration.
All milling machines have guidelines for proper cleaning and maintanance. The imes icore CORITEC ONE’s spray channels must be kept clean, otherwise they will spray off the target block materials. Essentially you will dry mill ceramic which will damage the material and break the drills very quickly.
You can see how little particles of ceramic and titanium dust can clog the lines.
Here we just used an ortho plier and orthowires to unclog the lines. It’s easiest to have the water spraying so you can identify the channels and see the immediate results.
In this article, we feature an upper left lateral crown that needed to be replaced due to recurrent decay. While the patient was getting numb, we defined the job description in the Medit i500 software and imaged the pre-existing crown, the opposing and the bite. We digitally cropped out the tooth to be prepared and proceeded with crown removal. Once the margins were refined and the tissue was displaced, we imaged the preparation in HD mode and processed the case.
Once the digital models were rendered, we launched the integrated CAD software that automatically imported the pre-op, the opposing, the prep model, and the bite. Their relationship is preserved in the CAD software and no modifications were necessary. You have two ways to copy the pre-op; one way is to program the CAD software so it replicates the pre-op perfectly while the other gives you a raw proposal that you can then choose to adapt to pre-existing situation.
Direct Import of Models into CAD Software for Design and Mill
Once the case is designed in the CAD software, you can then take it to any CAM and Milling Machine to produce a restoration. Here we milled an emax restoration with the CEREC MCXL and the imes icore CORiTEC ONE at the same time so we can compare the final results. The CEREC milling machine produced a restoration faster by about 90 seconds but the final results of the margins by the CORiTEC Machine was far superior. Also, the CAM software, Millbox in this situation, allows us to choose a third drill that is 0.6 mm in diameter. This increases milling time but results in less overmilling than the 1.2 mm burrs that milll the intaglio of the CEREC Machine.
Please, take a seat, you should not be standing while you watch this.
Artificial intelligence by Medit i500 now identifies the location of your scanbody but it also automatically launches all that proper information into CAD software for instant abutment designs. Make sure to watch both videos. Enjoy.
Few things in dentistry that can be as frustrating as seating a second molar restoration, whether you are doing same day dentistry or having a lab made prosthesis delivered. Here is a protocol we recommend that you follow to dramatically reduce surprises and post op adjustments. In this particular clinical case a zirconia crown debonded and we elected to fabricate an in-office emax restoration. The sequence is as follows:
While the patient is anesthetized and you are waiting for the onset of anesthesia, capture the opposing impression and the arch models. Trim away the prep digitally and then proceed to the buccal bite capture
Do NOT capture the bite until you verify clearance. In the sequences of videos that follow, watch how we use the Medit i500 to capture digital pictures of the clearance
Once we verify clearance, we image the bite. You have the option at this point to see how well your occlusal stamps match the digital stamps if you want to. A large deviation may mean the jaw settled or the patient moved during the bite capture. Note that unlike conventional dentistry, you capture the bite here BEFORE the prep is finalized
Once you achieve isolation you can finalize the prep and retract the tissue and capture the prep. We elected to capture the preparation in HD mode
The case is then immediately imported into the CAD software for design and fabrication
A custom titanium metal abutment is milled in such a manner where the drills DO NOT touch the connection. The type of connection is predetermined by the blank manufacturer and the cylindrical part of the abutment is milled out. This makes the symmetric geometry of the abutment a bit tricky for some to handle as indexing it properly to manage the timing of the connection is critical for easy delivery.
It is a good idea to know the exact dimension of the screw access hole. You want to set the diameter just outside the channel so that you don’t have to do a lot of post production adjustments. if it is made too thin however, you can have a mis-mill and have to repeat it. We’ve found 2.5 mm the perfect setting for the DESS titanium abutments.
With the Meditlink software you can design a case and then export the designs and take them to any milling machine of your choice. In this demonstration, we use the CORiTEC ONE to mill out the metal abutment in 45 minutes. This procedure is not intended to be a single appointment visit so timing is not critical and you don’t place undue wear and tear on the milling machine.
The crowns were milled with two different milling machines. A Celtra Duo block was used and milled with the CEREC MCXL and retrofitted to the abutment to verify the fit and accuracy. The same crown stl was milled out of Vita material in the imes icore machine. The whole point of the demonstration is that you can take scans from any intra-oral scan, take it to CAD software (in this case exocad) and then export the case and take it to any printer or milling machine of your choice. You must make sure critical information is accurately transferred from your CAD software to your CAM software, which is generally the construction / project file that accompanies the STL files of the prosthetic components
The same crown was milled out of Vita’s Suprinity material in 20 minutes with the imes-icore CORiTEC ONE. Take note of the internal adaptation of the metal abutment and the restoration and how when it is flipped upside down, the restoration does not fall out easily!
For our advanced users, we demonstrate how to plan and manage a two unit molar case so they can deliver multiple chairside restorations in a single visit. There are numerous short-cuts to this treatment protocol and we present them in great detail during our courses. The limiting factor for most doctors is that they have a single milling machine and we show our users how to balance prep and mill time so that they can complete 2 units in less than 90 minutes.
In this case however, we present two restorations that were prepared and delivered at the same time. The sequence of steps are:
Anesthetize the upper right first and second molar
While the patient is getting numb, image the arch to be prepped, image the opposing, and image the bite WITHOUT the teeth being prepared
Reduce the occlusal height of your preparation but do not image them
Check your reduction visually or with the camera function of the Medit i500
Reduce more tooth structure until you have the proper clearance for material strength
Finish refining your preparations, displace the tissue, reach hemostasis, and then crop out the area of the model that you have altered
Image the two preps into that equation. Most people turn on the HD mode for capturing the margins
For distal extension cases, we recommend that you take the second bite. While imaging the second bite (NOT the left vs right bite), if the occlusal model turns green, it is a clear Indication that the vertical has no changed from the pre-op to the prep situation and that you will have minimal post-op adjustments to make. If the second buccal bite does not register in green, it should serve as a warning to you that the vertical dimension has changed
As advanced users, you quickly recognize what areas in the model need to be closed either with imaging or with the “close hole” options during the processing step of the Meditlink software. If you are familiar with exocad or other CAD software programs you can just ignore these areas as they do not have any clinical significance whatsoever.
Once the case is designed you can mill them with your milling machine of choice. The testing of materials, fit, and milling machines are a constant at CAD-Ray.com so we milled the first molar with emax material and the MCXL and the second molar, a Celtra Duo material, was milled with the Imes Icore CORiTEC Once
An immediate post-op bitewing X-ray was taken to verify fit and to make sure that there was no excess resin cement left behind in the interproximal area. The premolar mesial to the working field also needs to be replaced and will be in the near future
At CAD-Ray, we are constantly looking for solutions that will satisfy a clinician’s needs in a dental practice. For the better part of a full year, we have been developing milling strategies that can speed up the manufacturing process and increase the longevity of the drills and the instruments used in fabrication.
In this video, we demonstrate a sample crown milling simulation where we try and place the restoration in the block to render the fastest crown in the shortest amount of time possible, with little wear on the drills.
