How are your dentures different than what I am getting from my current lab?

ROE is a progressive full service laboratory. One big difference from other laboratories is that you receive a final base at the bite appointment. This ensures accurate fit, saves valuable chair time and allows the patient to confirm their denture fit and stability early in the process. We use the ESP technique (Esthetic Simplified Predictable) for our dentures: lingualized occlusion, BlueLine Ivoclar teeth, semi-adjustable articulators, processed bases, and Ivocap injection process. We also offer Staub Cranial, a 30 year old tooth set up systems that requires just your master casts, shade, age and gender. With this little information, we return a full upper set-up and a lower bite block ready to confirm the fit and tooth position. It’s 98% accurate and a real time saver.

How long has ROE been in business?

ROE has been in business over 80 years. We are a family-owned, second generation business.

Explain your process of quality control?

We have a team approach to delivering “restorations of lasting value”. From an assigned ceramist, multiple quality control stops throughout the process, to an assigned technical representative, we ensure that restorations leave our lab within the highest standards. ROE is pursuing DAMAS, a three-year quality management certification similar to ISO9000. This will set us apart from 98% of laboratories.

What do you do to ensure that I get a consistent result for my fixed restorations?

Assigned experienced technicians, CAD/CAM fabricated substructures, computer controlled stone measuring, high powered magnification, highest quality name brand materials, digitally controlled die space, and solid model duplicate are just a part of our C&B system. In addition, all doctor specific preferences are logged into our computer and checked by your technical representative before leaving our lab.

What do you want me to send the lab when restoring anterior teeth.

Include a full face photograph, study models with a description of how it is to be used, bite registration, digital shade correction if necessary, fox plane registration, full arch models that include the full labial peripheral roll. We have a comprehensive Big Case Checklist available upon request.

Explain the different surgical guides offered by ROE.

We offer model based and CT based surgical guides. Model based guides are based on the GuideRite system and the CT based systems we work with are NobelGuide, iDent, SimPlant, and BlueSkyPlan. We developed a web site specifically for this all-inclusive service www.dentalimplantplanning.com.

How are TMJ and Bruxism splints designed differently?

Typically TMJ splints have cuspid guidance/disclusion and protrusive disclusion. Bruxism splints are designed with a flat occlusal plane.

On splints what is the difference between your splint materials?

For ortho splints we use a standard powder/liquid methylmethacrylate. We also use Eclipse, which is a stronger, monomer-free material; Ivocap, which is heat and pressure processed, and Flexite which is a virtually unbreakable material.

Do you work with digital impressions, what happens when I send you a file?

Yes we do, iTero, Lava COS, and Cerec. When the file is received the data is evaluated for accuracy, and then forwarded to the model making facility. In most cases we can begin working on your restoration before we receive actual models, allowing us to virtually design any type of material to your very accurate impression. Once your models are received, the restoration is completed and returned to your office. The initial model and die is included in the price of our restorations.

How does ROE handle complex cases?

When the case arrives in it is checked by our lead technician. The dentist is called if clarification is needed, and the appropriate assignments are made. The case is flagged when multi-departments are to be included, and the case is followed carefully by our technical consultants to ensure quality and outcome. We offer a Big Case Checklist to ensure we have the proper information to being your case.

Do you markup implant parts ordered by ROE?

The parts are marked up due to the time involved in ordering, our expertise, and the fact that we then take responsibility for those parts.

Why does ROE charge shipping?

We prefer to separate our fees so our customers know exactly what they are paying for. Our fees are tiered, and once a client reaches $3500/month average, the delivery fee is removed. Generally the delivery fee is $5.50.Many national labs charge much more than we do, and charge both directions. All laboratories charge delivery fees - many just incorporate shipping charges into their fees for the various services.

Is all Zirconia the same, what is different between Lava and Procera etc?

Not all zirconia is created equal. Yes, zirconia can be chemically similar, but once processed, the mechanical and optical characteristics can be significantly different. Which can mean a significant difference in the final restoration for your patients. Lava is processed differently then other zirconias with a “trade-secret formulation designed to enhance the translucency, marginal fit and strength”. Procera is milled in the ‘green’ state, then sintered to sized and density.

Which is better emax or Zirconia?

It depends on where you’re using it. E.max CAD is very strong, so it works well in the posterior, but can be somewhat opaque.  E.max press and layered works best in the anteriors.  Zirconia can be used for both anterior and posterior areas - remember zirconia normally is the coping only. This is changing and now we offer full-contour zirconia. Still, it will be opaque, but will exhibit strenth beyond any other restoration.

Do you suggest Zirconia bridges? If so how many units do you suggest?

We’ve been fabricating zirconia bridges for many years. In Procera, the span can include up to 2 pontic units. In Lava the span can be as many as 4 pontics. Procera is also able to mill bridges up to 14 units. We have many suppliers for zirconia frameworks and the sky is nearly the limit on design.

What are the differences between your different levels of diagnostic waxing?

We offer multilevel BluePrint Diagnostic service. At level includes an adjusted model with white wax. Level II includes multicolor wax and pink gingiva. Level III is the same as level II but we include a prepared model and hard acrylic reduction stent. All three levels include preparations and provisional matrixes as well as a written plan indicating material suggestions and observations. All cases are mounted on semi adjustable articulators.

Do you do Captek?

Captek is not longer available through our laboratory.

What is the best way to do a crown under a partial?

Send the partial to us in an impression, and allow 8-10 working days for use to fabricate the crown. Or you can use what we call the “Twin Clasp Technique” which is a special impression to allow us to make a duplicate clasp for crown fabrication. This technique is available on our website.

Do you do metal free partials, and what is the differences between them?

We carry Valplast, which is a nylon thermoplastic material guaranteed by Valplast not to break. The clasps can be adjusted by heating them with a flame (flame must not touch the material). We also offer Flexite, which is a flexible yet strong, however mostly use this material for combination cases with metal substructures.

What kind of metal free partial clasps does ROE provide?

We provide two, Valplast and Acetal Resin. Valplast can be clear or tissue color, and Acetal comes in 16 Vita Shades. Acetal is our most popular. It is a copolymer thermoplastic that is very dense, hard and with care can be long lasting.

I have heard about Staub Cranial, what is that?

Staub is a denture 30 year old denture set-up system that uses a precise mathematical formula to calculate the position of the teeth, based on anatomical landmarks. It allows our customers to complete dentures in three predictable appointments. This method can only be used with a fully edentulous patient. Simply send maxillary and mandibular models and include the shade and the patients’ gender and age. We will return a full maxillary set-up and a mandibular bite block, both on final processed bases. At this appointment you will capture the bite and return the case for the lower set-up and processing of both dentures. We’ve experienced 98% accuracy!

Do you do orthodontics?

Yes we fabricate many commonly used orthodontic appliances.

What type of materials do we suggest on an anterior crowns?  

In the anterior we would suggest either Empress Esthetic or e.max cut-back. For added strength we fabricate layered zirconia such as Procera or our in house CAD zirconia.

What cement or bond material should I use for eMax?

We recommend using what you are accustomed to for your porcelain to metal and all-ceramic restorations.

How long does it take for a denture or partial repair?

Typically one day. When metal is included, the process can take 2 – 3 days. Patients are welcome to come and wait for repairs and relines. We have a nice waiting room and shopping in the area. Please call before a patient is being sent to the lab.

Is it recommended to make a bridge w/ a natural tooth as an abutment and an implant?

No it is not.

Can I make an emax bridge?

Yes, ROE can press e.max and make a bridge up to 3 units.

What are the steps for fabricating an implant retained denture?

This is a complex answer and is based on the type of restoration. If we are beginning from scratch, send us conventional denture impressions or implant level impressions. We will return either a processed base with implant parts or a triad base, both for the bite registration. Once the case is mounted, we will proceed with tooth set-up and either finish the case if the implant parts are already incorporated in the case, or return the case to you for implant impressions. We have an Implant Protocol and other forms in our Customer Center that covers all the steps.

Questions on different type of attachments.

There are many different types of attachments that we use here at ROE. It is best to call and speak with Mark, BJ, or Joe.

Porcelain chipped from bridge, what steps should be taken to repair?

The standard repair for chipped porcelain is to etch the porcelain, then bond composite to the area. If the chip is more extensive, prepare as needed for esthetics and bonding, capture an impression and allow us to fabricate a veneer.

What are the steps for fabricating Scan,Surgical and implant?

We have a excellent, easy to “CT Steps to Surgical Guides” which explaines the process step-by-step. To begin a fixed case we need full arch upper and lower silicone impressions (or master casts), a bite registration, a study model if avalable, and a complete CT Order Form. To begin a removable case, please send the patient’s existing denture to be modified with radiotranslucent markers. A duplicating techniqueis available. If the patient does not have an exhisting denture, follow proceedures for fabricating a new denture.  

Once the radiographic template (scan guide/applaince) is fabricated, the patient returns to the general dentist for a try in. The guide must fit very acurately. Then the patient receives a CT scan. The DICOM data is sent to ROE where we plan the case and host an online meeting to finalize implant location. Once complete the guides are fabricated and returned to the placing doctor.
