The revolutionary one-visit crown: CAD/CAM not required

On that day, dentistry is becoming more and more popular and easier than ever before - and Rhodium OVC3 is leading the way.

There is no doubt that many of you read my top 5 test drive columns on the December issue. In this column, one of my favorite new dental instruments for 2017 is OVC 3. Although I have a chance to give you a product brief in December, why do I like it, I really think that in order to do justice to the product, it needs a full article. So sit back and hold your feet up to see how OVC3 can become a dramatic world changer in the dental world.

Dental CAD / CAM has been believed to have been with us for more than 30 years. I remember I took a fixed prosthetic course in the fourth spring of 1987. I can clearly remember that one of the lecturers described a new concept of crown based on "Computer Aided Design and Computer-Aided Manufacturing" and therefore CAD / CAM. During the course of the lecture, the lecturer told us that although the system was in a very early stage, he could foresee a period of time in the future and that the use of impression materials would be limited...if they were needed.

The OVC3 process is a simple four-step process.
I remember that it was like yesterday. The reason is very simple. I really do not like to take impressions. This is not to say that I am bad. I think my skills are "enough", but the whole process (especially in the late 1980s) is complicated, messy, and people hate it. I remember thinking in the speech: "If I do not need an impression, I need to buy one of them." It's interesting now because the "something" doesn't seem to have a name yet, or if it does, my tutor doesn't know what it is.

The device became CEREC, it really changed our world. It welcomes the full range of digital impressions and office milling.

Of course, starting from 2004 to 2005, we began to see an increase in the entire category of digital impressions. Then, the entire product category broke out around 2010, and now we continue to see new players entering the acquisition market. We also see many companies entering the market together with factories. This allows doctors to mix and match their preferences and budget with what they need to complete their tasks.

But let's stop and take a breather in this discussion. There are many or many reasons why fixed prostheses are game changers for patients and providers on the same day. From patient satisfaction to the Office’s increased hourly profitability, most of us who have practiced for one to two years can clearly see the reason for the day’s dentistry. Why the problem has been solved for a long time.

As a profession, what we are asking now is not "why" but "how." I mean:

• Choose the right acquisition unit

• Choose the right milling unit

• Learn to use the acquisition unit

• Learn to use milling units

• Learning Design Software

• Decide which material/block to buy and use

• Decide (some materials/blocks based selection) need to buy oven

• How much chair time is again based on material/block selection

• Determine what adhesive system to use

Then is the biggest "how" of all of them, "How do I pay for all these expenses?" Here is an example: I recently spoke to a dental salesperson who had no special financial interest in this particular area of ​​dentistry. She told me that one of her clients told her that since most dentists are now doing inlays instead of secondary direct repairs, integrated dental sales will soon drop dramatically. She wants to know if this is my opinion either. I asked if she recently purchased a CAD/CAM device. She said they had. My answer was "I think so." This is the unfortunate part that sometimes occurs in such purchases. Abraham Maslow, the father of behavioral psychology, once said: “When you have the only tool that is a hammer, every problem begins to look like a nail.”

If I tell you that you can provide a solution for patients, let you do a one-time visit without nearly six-digit hardware investment. This is the concept of a company named Rhodium and their dental equipment OVC 3. The product is named after the concept of disposable crowns and may well change some aspects of our crown on the same day.

OVC 3 is a rather unique idea. The system consists of a hybrid composite/ceramic or lithium disilicate preformed crown that is designed for various colors of molars or premolars. The difference between the OVC preparation 3 and a traditional crown preparation is that the OVC 3 preparation requires reducing the occlusal surface only, if possible, keeping the height of the profile above the profit margin. This allows the teeth to maintain their maximum internal strength.

OVC crowns are suitable for various posterior teeth. The same plastic "blank" as the OVC is used after the bite reduction is reduced to determine the proper size and whether a sufficient reduction has been achieved. After proper installation and isolation is complete, natural teeth are etched and adhered to any bonding system that is familiar to the doctor. During the manufacturing process, the OVC itself has a layer of composite material added to the crown interface area. OVC is pressed in and cured. The excess composite material is then removed and the system is cured from multiple angles by high intensity curing light. Once properly cured, the margins are finished and polished

The OVC 3 kit comes with everything needed to complete the case. This includes a special matrix strip, plastic "blank" and traditional plastic wedges. There is also Rhodium's special “stretch wedge” that provides greater separation forces than the cross-section matrix rings and the OVC porcelain crown itself.

Over the years, practice management professionals have been telling doctors that the greatest potential source of revenue in our practice is the undissolved dentistry in our patient charts. This is definitely what I agree with. This is definitely what OVC can help. Many patients have reason to refuse to complete the crown, the two most common of which are cost and time. Many people simply can't afford the crown. Many people don't have a job to get them off work for two Crown visits.

In my office, we have positioned the OVC as an affordable choice for more expensive lab-made crowns. In our office, we often face the clinical situation that the teeth are too fine to support direct composite materials. But what can we provide if the patient does not have the two appointments needed for finance or crown? OVC offers dentists the options they have been looking for without the need for substantial capital expenditures. Because the cost of a single OVC 3 kit is lower than that of a traditional laboratory-made crown, and the time required and the appointment time are less, the cost savings can be passed on to the patient. is one professional dental supplies website which supplies dental equipment in UK with competitive price and high quality.
