Function and esthetics are the two primary goals of excellent treatment. Achieving them both simultaneously requires the right tools used with the best skill possible. The Dento-Facial Analyzer is my go-to for gathering information I can use to improve the outcome of mounting a maxillary model.
In parts 1 and 2 of this series, I introduced the Dento-Facial Analyzer and began the discussion of how to capture records with it. Here, I’ll complete my overview of a solid technique:
Completing the Dento-Facial Analyzer Technique
… Ensure the Dento-Facial Analyzer is positioned level to the horizon both when looking straight on at the patient’s face from the anterior section and looking at them from the side. It should be level in both planes of space. Then, allow the bite silicone to set and have the patient hold to verify.
Remember that the main use of the Dento-Facial Analyzer is transferring three significant pieces of information. This is either intended for the laboratory or for when we mount our own models.
The first piece of information is the maxillary relationship – the distance to hinge access – which means it’s very important that the central incisors on the maxilla are seated against the plastic bite plate.
Second, we are transferring information about the occlusal plane and the incisal plane. From an incisal plane perspective, it’s crucial that the plate is level to the horizon as we look straight on at the patient once we have the analyzer in. The vertical rod on the analyzer indicates the center of the face – the facial midline – which can be given by the central philtrum of the upper lip or the center of glabella.
You should also look at how you’ve captured the record from a lateral view. This ensures the occlusal plane – the relationship of the cant from anterior to posterior teeth that exists in the patient’s face – is transferred accurately to the lab or onto the articulator. The side bar of the Dento-Facial Analyzer should be level to the horizon.
