We are always looking for new ways to be a technical resource to you in your daily practice, and to that end, we will be constantly updating the technical FAQ list below as new questions come in to our lab from Doctors that are working on patients cases and need help/assistance/advice in order to successfully complete the case.
If you have a specific technical question that you need answered, scroll down to our Q&A form where you can submit.
We need your help in building out this FAQ section to be a robust technical tool that will help and inform your colleagues on cases who may find themselves with the same questions:
There are two options to consider (Option 1 is our preferred method but both work well).
*Keep in mind that you need to separate this and mark it so that the lab does not confuse it for a bite.
It is not necessary to cement with white cement when placing veneers on tetracycline stained teeth unless otherwise decided by the dentist and the technician. The lab takes into account the stump shade and blocks out using specific formulas for opacity.
Also check out the material Renamel pink opaque fabricated by Cosmedent, Inc. This material neutralizes dark stump shades. Visit Cosmedent’s website for further information on this product at http://www.cosmedent.com.
While each dentist has been trained differently on occlusal theory, the main idea here is how to preserve the bite of your patient while preparing the full arch.
First take a full arch preoperative bite; this allows you to be sure the patient is biting down properly and gives you something to refer to throughout the process. You will probably prep one quadrant at a time; as you finish preparing each quadrant, you will reline your original bite over the preparations until you have made your way around the arch.
Digital photography has changed the way the doctor and lab communicate in a very positive way; photos have become crucial in the success of esthetic cases. The following list is a helpful guide to follow, but double check with your technician depending on the specific case:
For Study Models and Treatment Planning:
If possible, do your own sketch of the patient’s shade including any of the characterizations or translucencies you can see.
Next, photograph the adjacent tooth we are trying to match using the shades you choose for the shade sketch.
Try to level the shade tab and the tooth so that any photographs taken have the flash hitting the same portion of the tooth.
The following materials combine well for veneer and bridge cases:
When executing combination cases with crowns and veneers, it is more effective to keep everything the same material.
For crowns and veneers, follow these combinations:
*Emax and empress should not be combined with feldspathic as they are different porcelains and while the shade may be the same, the metamerism will make the materials appear to look different.
