NECESSITY OF PRE-OP IMPRESSIONSTaking pre-op impressions will mean you will have to take additional operatory steps with the initial visit of your patient but your end result will be well worth it.

It is a fact that dentist who take pre-op impressions will have fewer repairs, saving valuable time and money. It will help your dental lab out by having a model to compare and evaluate and most importantly, patient satisfaction as an end result is more predictable.

For the lab, having a pre-op model offers valuable information for any case that is three units or larger. After a prepped model preparation and articulation, we can run a putty index and hand articulate the reference of the pre-op model. We will be able to clearly see your patient’s smile, vertical and horizontal position of the teeth, as well as, the size and contour. This information is important not just for anterior bridge esthetic design but is critical for functional success as well.

Additionally, pre-op models in the fabrication of posterior three unit plus bridges can be helpful in the design over an edentulous area because we can double check the occlusion. It’s even more critical to have pre-op models for a case that does not have a posterior stop.

Also, from pre-op models the dental technician can work with the dentist to make changes in the patient’s dental appearance. With the Rx

description and instructions, pre-op models can be shortened or lengthened, or the facial bulk reduced or increased before an index is made. We will then have a visual for comparison of the new look to the former. From the laboratories perspective, we want to provide a quality restoration that you and your patient will love. Please be sure to include a pre-op impression

with every case to help us accomplish that.

LARGE ENOUGH TO SERVE YOU PROFESSIONALLY,

All ceramic crowns are definitely here to stay. With the media advertising and patients more informed of the advancements in dental restorations, many of our doctors are asking, “What’s the best application for the use of these new, exciting products?”. We are going to answer that question. We want to share information that will make it easier for you, the dental care professional, to make a decision as to the type of restoration that is best suited for your patient, when considering an all ceramic crown. Also placing the right restoration in the proper application can help determine the life of the crown.

In our lab, we us the Empress Esthetic and E-Max pressable ceramic crowns, as well as Zirconia Core milled crowns. Let’s begin with Empress Esthetic.

We recommend that Empress Esthetic be used as Single Full Contour Crowns, or Veneers only on the anteriors of the maxillary or mandibular. Empress can possibly be used on the first bicuspids of either the upper or lower provided there is enough occlusal clearance, lateral and protrusive movements are clear, and your patient is not a bruxor. These clearances also apply to anterior full contour crowns. If using Empress Esthetic for veneers, especially on the lowers and if your patient is a bruxor, then you’ll find a product we consider more viable for that application in the next section on E-Max pressable.

Empress Esthetic is highly translucent and while this creates a beautiful natural looking crown, it also creates some limitations such as use with a darkly colored prep, a prep with metal pins, or metal implant abutments. If Empress is used with these preps, the prep must be cut back and built out with colored paste to mask out the preps undesirable shade before the impression is made.

E-Max Press is the workhorse of all ceramic restorations. E-Max Press offers 16 shades in Vita A-D, and 4 bleach BL shades.The pressable ingots come in 4 levels of translucency, LT, HT, MO and HO. HT, High Translucent ingot allows more of the stump shade to show thru the final restoration. LT, Low Translucent ingot allows for less of the stump shade to show through. The MO and HO ingots are both very opaceous and are designed to mask moderate and heavily discolored preps, and metal implant abutments. We recommend that if the discoloration is heavy enough to require one of the OT ingots, or the abutment is a metal implant, you should consider choosing a Zirconia coping.

The results will be more of a definite blocking of discoloration or metal.

We recommend the E-Max Press for the following applications: Single Full Contour Crowns in both the anterior and posterior regions of the maxillary and mandibular, Single Anterior Crowns using a cutback and layering technique, the LT ingot is often suggested in this application. Anterior Bridges, in either the upper or lower, with no more than 1 pontic. Bridges are not recommended in the posterior areas of either the upper or lower, full contour inlays and onlays, the HT ingot is suggested for Veneers pressed in full contour. If you are dealing with a

patient who is a bruxor, then HT Pressable is an excellent substitute for Empress Veneers on the lower, especially if done in full contour.We will be glad to provide you, at your request, prep guides for your operatories, and cementation guides for both Empress, E-Max Press, and Zirconia Core Crowns. Zirconia Core Crowns are one of the most amazing advancements in dental restorations. But, zirconia by whatever name you call it, is still zirconia. We’ve lost count of how many name brand zirconias are out on the market, Lava, Zeno, Everst, Prizmatik, CZ, Crystal, Cercon, are just a few. And what makes each better than the other? Well first that’s the wrong question. not what makes them better but what makes them different.And that difference most often lies in the operating system, the scanner, the axis

milling machine, the sentering furnance, and even the number of different shade blocks offered. Their differences don’t make them better, but dictates how you, the dentist, or the lab will choose to use what they offer. First of all, no system is perfect. NO ONE system does it all. These differences are where the lab technician can be of great help to you. When you send us a case requesting a zirconia restoration, it is our responsibility to evaluate that case and determine the best application of product for you and your patient.

Where can you use Zirconia Core Crowns? Anywhere you want to. From a single unit anterior or posterior, 3 unit or 4 unit bridges and more, inlays and onlays, upper or lower, anterior or posterior, up to and including a full arch. It’s all in your lab tech knowing which zirconia system will give you the restoration best suited for your patient.

What about the bruxor? Do we still need to use the full gold crown or PFM’s with metal occlusions? Up until just recently most lab techs would agree this is the application to use, simply because standard types of porcelains would be used in the final contour of the crown over the zirconia coping, and may not be able to handle the immense wear exerted by the constant grinding and pressure. However, Crystal Zirconia has just introduced a full contour zirconia crown. This means the entire crown is milled from the zirconia block with no standard porcelains added. This crown can definitely handle the grinding and pressure of a bruxor’s bite. But there are a couple of factors to consider when using the crown relating to shade. This Zirconia is very dense and more highly pigmented than other zirconia. Even when perfectly matched to a shade guide, when placed in the mouth it may appear slightly brighter than in the lab or even in the dentist’s office, making shading a little tricky. Basically it’s a trade off. If your patient is a bruxor, but doesn’t want metal showing, or insist on an all ceramic crown, then this crown is best for that application, providing they understand the slight shade difference that may occur.

We hope this article has given you information that will be helpful to you in making decisions about the type of restoration best suited for your patient. With these advancements in all ceramic crowns, you can confidently choose to use all ceramic restorations in every situation.

Communication Is KeyGibson Dental Designs wants to be sure that your needs are met. To

follow the front page article on pre-op impressions, which are very important, we also want you to take an impression when something doesn’t fit just right.

When you receive a case, should that crown or bridge have an open contact, open interproximal space or open occlusion please place the crown or bridge in the patients mouth in the correct position. Now take a new impression with the restoration in place. Pull the impression after it cures, leaving the restoration in the impression, seated in the correct position. Using this technique when we pour up the new model we will immediately be able to see the discrepancies that need to be repaired.
