Digital Models - All Impression Systems Welcome

ROE has once again made a major investment in digital technology. To facilitate an efficient and predictable means of producing models from digital scans, we purchased two of the finest model-printers available. With this equipment we are n

o longer inhibited by the delay times of model-producing companies and delivery services. Production is more streamlined and model-fabrication is now a ROE controlled process.

Doctors who are investing in digital impressions may be interested in model-free dentistry. This is possible for many posterior cases. However, to fabricate a veneer, bridge, layered crown, lower partial denture, or bite splint, it is still necessary to work from a physical model.

Triple Tray Check Bite

It is known that patients frequently bite differently when anesthetized, and after being open for an extended period of time during the preparation procedure.  So, Dr. Damon Adams, visiting lecturer and editor-in-chief of Dentistry Today, promotes a unique method of ensuring an accurate bite when taking a dual-arch (triple tray) impression. The first step is to capture a centric occlusion (CO) bite on the contralateral (non-prep) side prior to administering anesthesia and before tooth preparation. When taking the final quadrant impression on the prep side, the clinician will use the contralateral bite to confirm accuracy of closure. In other words, the clinician can observe the initial CO bite (seated in place on the contralateral opposing arch) as the patient slowly closes into the impression tray on the prep side. The contralateral CO bite will serve to “guide” the patient into a proper centric. Without a verification technique such as this, slight variations in bite often go unnoticed, creating lengthy occlusal adjustments with unnecessary stress for the clinician at the delivery appointment. 

Protrusive Considerations

When preparing anterior teeth, it is always a good idea to have the patient perform protrusive and lateral disclusion after the initial preparation. It is important to verify that adequate space has been provided for functional movements.

Occlusal & Contact Issues - Simple as +/-

In order to minimize chairtime and maximize the value of our restorations, we have established an innovative system for communicating and implementing preferences for interproximal and occlusal contacts. Proximal contacts have been separated into two categories, ‘fit’ and ‘shape’. Proximal ‘fit’ determines the amount of contact ranging from ‘extra light’ to ‘tight’, and the ‘shape’ ranges from ‘point’ to ‘extra broad’.  Occlusal contact preferences focus on the amount of ‘resistance’ to the antagonist. The system is uncomplicated, from a communication perspective, and has been implemented in both our fabrication process and final quality-control evaluation. If you are interested in discussing your preferences and reducing chairtime, your Technical Consultant will provide information on our system and discuss how your feedback will refine our fixed restorations.

Sphero-Flex - A Solution for Divergent Implants

When a freestanding appliance is desired, but divergent implants present a challenge, Locators and O-Rings are not always the best option. Often, the total degree of divergency between all the implants is greater than the aforementioned attachments allow, or accommodate. In such a case, we recommend a unique product called Sphero Flex. This system uses compensating plastic sleeves (figure 2) to correct the angulation, and eliminate what the manufacturer, Rhein83, calls “insertion trauma”.

With this correction, the appliance should seat easily and the inserts will wear less.

As with other systems, collar height, space, and angulation must be determined prior to ordering the components. Please send an implant level impression and a duplicate of the patient’s appliance. If fabricating a new appliance, ROE will order the parts during the prosthetic development. 

Send A Smile

We always request that photographs be included with anterior restorations. While pictures are also beneficial for shade and texture, they are invaluable for contour, length and esthetics. It is important to know that for contouring purposes, our favorite image is a natural smile. This image shows us critical soft tissue considerations, such as neutral zone and lip position. Too often this image is not included with the case. Thanks for your help!

All-On-4 - Total Treatment Support

When restoring an All-On-4 case, rely on ROE for chair-side assistance. One of our three Clinical All-On-4 Specialists will visit your office on the day of implant placement and convert an existing denture into a hybrid. If requested, they will also advise on abutment and parts selection as well as impression and pick-up techniques. ROE has completed hundreds of chair-side conversions and we would like to share our expertise with you.

ROE offers the complete solution for this popular treatment option: immediate dentures, conversion, guided surgery, bone reduction guides, treatment planning, and of course final restoration. The fee for chairside denture conversion is $600, which includes all laboratory work. Travel expenses will apply when out-of-town visits are requested.

PFM's & Full Cast - A Whole New World

ROE pioneered CAD/CAM PFM’s over a decade ago using CAM printed plastic patterns. Now, many years later, thanks to sophisticated dental engineering, the majority of our full gold crowns and PFM restorations are manufactured using three of the industry’s state-of-the-art systems.

After the design stage, restorations are fabricated directly from the selected alloy, without investing or casting. The benefits to the dentist include low, flat fee, (except 55 Au) reduced fabrication time, dense porosity free castings, digital design file storage, unsurpassed alloy purity, and lot number traceability. Below is a brief summary of how three of our restorations are currently being produced.

Full Cast Crowns – Full-cast restorations are milled in Röders RXD5 machines from solid pucks of either yellow noble (2% Au) or yellow high noble (55% Au). The fit of these milled restorations is unmatched, and the porosity-free, metal blank provides incredible smoothness and density.

Base Metal PFM – Using our Datron D5, an amazing German milling machine, these restorations are sculpted from a solid puck of CoCr. Virtually any design is possible, including long-span bridges, rest seats, and some attachments. It is by far the strongest alloy we offer, and porcelain adhesion is excellent. Thanks to this robust milling machine, it is the finest PFM we offer.

Noble and High Noble PFMs – Created with Selective Laser Melting (SLM) this additive technology builds the coping layer-by-layer. The process is extremely accurate, creates less product-waste and saves time. Unlike some conventional castings, each set of copings is created from 100% new metal. Presently, these restorations are limited to 3 unit bridges.

  

Although all-ceramic restorations represent the most popular choice of our clients, metal-based restorations remain a proven option and an excellent choice for many situations. Rest assured, when you chose ROE, you and your patients are getting the most advanced restorations available.
