Premium Products Help Laboratory Owner reach Ambitious aspirations

One company provides equipment, materials, and now a digital denture solution

George Zoller, CDT, had a clear vision for Mountain Dental Lab when he and Danny Ingle joined forces as owners approximately 13 years ago. Zoller had previously helped build another successful laboratory before working as a consultant for a few years, and he brought that breadth of experience to the new venture, which he and Ingle were able to mold to their liking.

“We were not interested in owning a commercial laboratory and having impersonal relationships with clients,” Zoller says. “We wanted to be recognized as a relationship-oriented laboratory. We wanted to really feel we were a part of the dental practice and that we brought value to the dental team. We wanted to be a resource in terms of education, materials, service, etc.”

The venture has been a success. Mountain Dental Lab is now a 13-person operation in a 5,000-square-foot facility, serving mostly regional clients but also some nationwide.

“We have found that clients who are of that same collaborative mindset gravitate toward us,” says Zoller, who specializes in implants and education. “The client that comes here is interested in what we do, how we do it, and how it complements the practice.”

Mountain Dental Lab’s slogan is, “We love being part of your practice.” The laboratory’s three guiding principles are being a part of the dental team, providing only the finest materials, and good, old-fashioned customer service.

Dentsply Sirona has helped the laboratory fulfill those promises. Zoller began using the company’s CAD/CAM equipment more than a decade ago and acquired an inLab MC X5 mill and an inEos X5 scanner approximately 2 years ago.

More recently, Zoller began using Dentsply Sirona’s Celtra Press zirconia-reinforced lithium silicate (ZLS) material. The chemical properties of this high-strength glass-ceramic create a unique microstructure that provides esthetics, strength, and efficiency.

The specially developed Celtra Press investment minimizes the formation of a hard reaction layer between the investment and the press restoration. Along with a lower pressing temperature than lithium disilicate, this eliminates the need to use cleaning fluid containing hydrofluoric acid.

“We fabricate a high volume of lithium disilicate restorations, and the first thing we noticed when we began using Celtra Press was the reaction layer, which saves an incredible amount of time,” Zoller says. “It is not necessary to put the restoration in an acid bath, worry about the fit, or worry about the margins chipping. Right away, that was a significant benefit for our workflow efficiency.”

Celtra Press also displays a high level of translucency that is unusual for materials with flexural strengths higher than 500 MPa.

“Empirical evidence in the laboratory confirmed that Celtra Press did what they said it was going to do,” Zoller says. “We were particularly impressed when we saw the vitality and the effect of this material in the mouth.”

To build that level of confidence among dentists, Zoller fabricated two crowns for each case for some clients—one from the prescribed material and one from Celtra Press.

“When dentists put Celtra Press in the mouth, they usually selected that option,” he says. “We now use it for almost every restoration where it’s appropriate to the shade.”

As Mountain Dental Lab continues to strive to provide its customers with the best products and service, Zoller has been investigating digital dentures. He has paid particularly close attention over the past few years to AvaDent Digital Dental Solutions, which has partnered with Dentsply Sirona to create Dentsply Sirona Digital Dentures, a digital solution that provides superior fitting dentures made with Lucitone 199® Denture Base Discs and Portrait® IPN® Denture Teeth.

“Clients are starting to call us about digital dentures, so we hope to offer that service soon,” he says. “I am really anxious to continue learning about the partnership between AvaDent and Dentsply Sirona and the developments that arise from it.”

The prospect of working on digital dentures with the same company that provides CAD/CAM equipment, materials such as Celtra Press, and more is enticing to Zoller. Dentsply Sirona Digital Dentures offer wide-ranging benefits; the denture materials are optimized to work with Dentsply Sirona scanning and milling machines but can be used with a wide range of equipment from other manufacturers. Whether laboratories choose to mill in-house or scan and outsource the entire process, Dentsply Sirona Digital Dentures offer flexible solutions and provide superior results for either Portrait bonded dentures or monolithic ones.

“It is certainly an advantage to have all systems running in the same gear, and to have the same company providing not only the materials but also the equipment for every need,” he says. “They can handle everything. When you are working through cases, it is nice to have that range of abilities within the same family. In the future, as the merger matures, it will be fantastic for consistency across the board.”

A New Generation of Dental Ceramics

The year was 1988 when dental laboratories first heard about an "Aesthetic Revolution". Up until that time, we had limited materials to work with, and doing cosmetic cases was challenging - to say the least. Porcelain was heavy-grained and metal framework had to be masked, making it difficult to refract light and produce natural-looking dental restorations. So, dental technicians settled for something that resembled glow-in-the-dark Chiclets. We all wished for something that was strong and translucent. There were many products that tried to hit this mark, but somehow, all missed due to their compromises in either strength or beauty.

Fast-forward to today. The science of dental materials has brought some tantalizing options to the table. We have Full Contour Zirconia (Zirconium Oxide), which definitely gives strength enough to eliminate metal frameworks, but doesn't always deliver aesthetically. Dental technicians also have Lithium Di-Silicate that has been the aesthetic standard for years, but it also has some limitations when it comes to multiple splinted units. Now, a new player in dental ceramics has taken the field! Celtra Press (Zirconia-Reinforced Lithium Silicate) from Dentsply Sirona has achieved all of the expectations dental labs, dentists, and patients, have been hoping for. It combines strength and beauty into one product that is versatile and translucent. We have been using Celtra in our lab for the past year, and have noticed several positive improvements that we believe have benefits for the clinician. 

1. Strength of 500 MPA: Fracture resistance at 500 MPA opens up possibilities for not only anterior, but posterior, bridgework, and implant restorations. All this without the dense, glow-in-the-dark look of other high-strength ceramics. 
2. High-Translucent Index: This material refracts light in a way that is similar to enamel rods found in natural teeth..The main reason for this is that the crystal particle size is smaller, so it not only looks more lively, but it blends well with the surrounding dentition, giving it a chameleon effect. This is especially beneficial for restorations that have high-translucency and a dark shade. 
3. Magical Margins: Celtra has a better resistance to chipping in thinner areas such as margins around implants, which allows us to use this material in areas where we once had to choose a less-aesthetic material in the past. 

In summary, we are excited about this new tool for the toolkit of aesthetic options, and how it can bring a "wow" factor to your dental practice. If you would like more information on Celtra, we have printed guides available for your office, or we will come to your office for a lunch and learn presentation at your convenience. Thanks for your time.

Dental Implants: In an expedient era, what you don't know can delay you

Dental Implants: 

In an Expedient Era, What You Don't Know Can Delay You

Today, dental implants are a standard part of a dental practice. They are reliable, predictable, and when designed properly, the restoration seats easily. Dentists have the option to use a stock abutment, or a custom abutment designed specifically for the patient in question. Custom abutments designed via CAD/CAM (Computer-aided Design/Computer-aided Manufacturing) further enhance the process by providing a custom solution for each case with the final restoration in mind, giving proper tissue emergence and strength for the desired material choice. Before any of that is decided upon, however, the impression coping and implant replica must be considered.

The challenge for dental labs doing implant restorations is lack of information. There are approximately 15 recognized implant companies in the U.S., and almost 200 companies worldwide making some type of dental implant. Many of these companies have their own connection type and parts, and many of these parts look alike. It is understandable that there would be some confusion when attempting to locate the correct driver or screw, or trying to determine which implant system it is just by looking at an impression post. Ordering the wrong part, or trying to find out which implant system it is can cost time and money for both parties.

Here are some practical steps that will insure success with every implant case:

1. Always communicate the type of implant system in its entirety. Many implant manufacturers have sub-categories. For example, Nobel Biocare Active vs. Nobel Biocare Replace. The surgeon who placed the implant will have this information in writing, which can be copied and sent with the prescription for the implant case to the lab.
2. Verify the platform size. Implant systems usually have three main measurements; the length, the implant size, and the platform size. The lab needs the platform size more than all other measurements. For example, an implant might be listed as a 3.8, when in fact the platform size is a 3.0.
3. When ordering an impression post, also order the coinciding implant replica/analog at the same time. This saves the dental practice money, and it saves the lab time. 
4. For implant cases covering 4 or more units, include a study model or a diagnostic wax-up to ensure the lab achieves proper restoration placement.
5. Allow a minimum of 3 weeks for the lab to return the finished case. Implant cases take more time to process, as more steps are required.

These are suggestions for making implant restorations a reliable part of the dental practice. Parts can be challenging, given the number of systems available. Mountain Dental Lab, Inc. has short implant lunch and learns that can help you and your staff with identifying and ordering the proper parts. We would be happy to schedule one of these for you - just give us a call at 828-665-2257 or email me at MountainDentalLab@gmail.com. Our goal is to support you in what you do, because
