If you’ve
considered switching to Vita’s 3D shades, now is a good time. Vita’s new Linear
Shade Guide includes the same shade tabs as the innovative 3D Master, yet the
layout is more intuitive for the guide’s intended use…choosing value first. The
Linear Guide includes a Valueguide for making the initial value choice. Once
the value family is chosen, the chroma and hue are determined. The 3D Master
has helped our clients with shade-taking for many years, and we highly
recommend its successor.
Since the 1980's ROE has published ROE Reports, a newsletter intended to keep our customers informed of changes in our laboratory and the industry. This is our on line ROE Reports.

Complimentary Shade Service
Calibration Tab |
1 of 3 Printouts |
Many
shade-taking systems have come and gone through the years. The challenges with
this technology have been cost, provider-support, and effectiveness.
ClearMatch, a system we recently launched, is showing promise. It is a software
that determines shade, value, and translucency from a chairside photograph. A
special black-n-white calibration tab and a Vita A2 shade tab are held
edge-to-edge to a target tooth, and a photograph is taken. The image is emailed
to ROE and analyzed with the ClearMatch system. Shade, value and translucency
maps are printed and provided to the ceramist (figure 1), and returned with the
completed case.
The quality of the photograph is critical to the success of the shade analysis. Proper flash and focus are the two key components. We recommend in-office training, which is available to offices throughout Ohio at no charge. If you are interested, please contact Alan Banks at ROE. Complete instructions can also be found on our website at the Shade & Smile Service page along with a link to a thorough YouTube video.
ClearMatch
software, developed a dozen years ago, is proving to be very effective. We use
it, along with ShadeVision and other tools, when patients visit us for shade
analysis.

In.a.Box Implant Pricing
With a
single phone call, a dentist can now virtually plan an implant case, order a
surgical guide with drills, order the implant(s), healing caps, and/or a
provisional. We call this service In.a.Box. Pricing. It was developed through a
partnership between ROE and BlueSkyBio, for implants that are compatible with
Zimmer, Astra, Straumann, or Nobel. This service is designed for ease-of-use to
help reduce office inventory, and save time and expense, when ordering
components for surgery. When cases are planned virtually, the implant size is
determined. At this point, everything you need to place, protect, or
provisionalize can be ordered.
An economical option in this service is the Direct Cut Kit from
BlueSkyBio. This kit was developed for a one-drill protocol for an osteotomy.
This computer-guided package includes a surgical guide, the implant and healing
abutment, one drill, and the final screw-retained restoration. The total cost
is $909.
3 Solutions to Cement Clean-Up on Implant Restorations
In the last couple of years there has been a lot of chatter
concerning the effect of residual cement on implant cases: bacteria build-up,
peri-implantitis, bone loss, etc. Although there are many methods of managing
cement, we would like to offer three.
The number one method of eradicating these
issues is, of course, to eliminate cement altogether, and choose
screw-retention. We have witnessed a surge in one-piece, screw-retained crowns
and bridges. Our most popular is a zirconia/titanium hybrid (TLZ-SR) that is
very durable and esthetic and only costs $299.
Another method is to request a two-piece
restoration, which includes a custom abutment and a crown designed with a hole
in the occlusal or lingual surface. This allows simple clean-up through the
following method: seat the abutment using a thumb driver; place a cotton pellet
in the access hole of the abutment; insert the crown to check margins, contacts
and occlusion; cement the crown in place; remove the cotton pellet before the
cement hardens; unscrew the abutment through the hole; remove the crown and
abutment together; clean the excess cement; torque down the cleaned restoration,
and fill the screw hole with composite. Be sure to have an abutment removal
tool, or a driver that can be reversed, when using a friction-fit system, i.e.
Zimmer Dental.
A third method is to order a duplicate resin die. This die can
be used for “cement pumping”. Here are the steps: torque in the abutment; check
margins, contacts and occlusion; place cement in the crown; seat the crown on
the duplicate die; clean the excess cement expressed at the margin, and
transfer the crown from the die to the mouth.
Spear Education – Class III Treatment
We were recently educated by Dr. Frank Spear
on treatment options for Class III patients. These patients are usually offered
3 alternatives: maxillary or mandibular orthognathic surgery, orthodontics, or
restorative treatment.
If the patient will
not accept the first two options, the doctor must develop a functional,
restorative occlusal scheme. Dr. Spear offers advice based on his extensive
experience. Class III relationship allows the patient to slide into an
exaggerated protrusive position without anterior interference. This slide can
become habitual. When the patient is restored to normal occlusion, with
standard overjet and overbite, this habitual slide will meet a major
interference, leading to wear, parafunction, or worse. Dr. Spear suggests that
the best occlusal scheme is end-to-end with little-to-no overjet, and minimal
anatomy in the posterior. At this point, the patient has maneuverability and
stable occlusion.
New Denture Teeth
Last year we began suggesting Pala Mondial® teeth by
Heraeus Kulzer for hybrids and overdentures and have noticed improved results.
Our decision was prompted by the claim of the manufacturer, as well as
prominent institutions, that the teeth are stronger than those of other tooth
company’s and that they offer an increased ‘bond’ to acrylic. Thus far we
agree. Mondials are also more esthetic than other brands, are compatible with
Vita shades, and are preferred by our technicians for set-ups. For these
reasons, we are using the Mondial line as our standard, premium tooth. If you
would like a mould guide, please visit the denture page of our web site. Shade
guides are available by calling our laboratory. Ivoclar BlueLine and Dentsply
BioForm are still available.
Master Cast Size Request
Due to our digital fabrication process, all master casts are
scanned to allow the digital design. Often, the dental office provides mounted
master-casts that are too large for our scanning equipment. When we receive
these casts, we are forced to separate the model from the mounting plates,
reduce the size, scan, and then remount. By limiting the size of the casts to a
maximum of 60mm high by 90mm wide, this extra procedure can be avoided, and we
can ensure the most accurate digital reproduction.
