Helpful Hints And How-Tos
Please find the below helpful hints and how to guides to assist your patient in getting the most accurate restoration possible. Additional how-to information can be found within its related product throughout our website.
When the patient has an existing partial and declines to provide the partial to our laboratory for crown/bridge fabrication, we can still fabricate the restoration to fit the partial by utilizing a partial index. See the provided step by step illustrated instructions for the creation of a partial index. Please notice that the images labeled Figure 8 through 11 will be fabricated within our laboratory. We also typically fabricate our matrixes using non-precious alloy instead of duralay, to prevent breakage during fabrication of the restoration.
Bite Stick for Setting the Occlusal Plane
We recommend sending bite sticks for multi-unit anterior and full arch restorations. The stick bite is useful for both anatomic wax ups and fabrication of the final restorations. To mount the case using the bite stick, the bite stick is put in place between the models, just as it was in the mouth, and the models are arranged in the articulator so that both the left and right sides of the stick are the same distance from the table top (parallel to the table top). Once the models are mounted using the bite stick, we can now place the incisal edge position/ occlusal plane level to the horizon, regardless of the intraoral condition.
Taking a stick bite is quick and easy. The expense of the minimal time required for making this simple, but valuable tool is far outweighed by the value of preventing inaccurate wax-ups and final restorations.
Bite Stick Technique
1. Find or create a reference to the horizon. Using a level, place a strip of tape on the back of a door, or use the top trim of a window or door, assuming it is level.
2. Have the patient stand in front of the reference to the horizon.
3. Inject syringe material over the lower anterior teeth and ensure it is enough to express onto the facial side when the patient closes
4. Have the patient close.
5. Add more syringe material to the incisal 1/3 of the facial side of both upper and lower anteriors.
6. Place a brush into the syringe material and position it level to the horizon.
7. Cover the stick with extra material for stability.
8. Remove the bite stick from the mouth and send it to us with the other case materials.
What Type Of Smile Does Your Patient Desire?
When sending a diagnostic wax-up, fixed restoration which includes the upper anterior, or upper partial/denture case for which there is no existing dentition or restoration that the patient likes and wishes to duplicate, please utilize the LVI Smile Catalog. The LVI Smile Catalog allows the patient to choose from 12 distinctly different styles. Simply inform us on the Rx which style the patient desires and we will use it for fabrication of the prescribed product. Of course, changes can be made as necessary to fit the specific patient’s desires.
