Mounting the maxillary models in three reference planes to the hinge axis and acquiring the esthetic information of occlusal and incisal planes are important both diagnostically and when sending information to the lab.
Achieving both function and esthetic information simultaneously is a great advantage nowadays offered by the Dento Facial Analyzer, which allows us to gather this information more easily to improve the outcome of mounting a maxillary model. These two primary goals; function and esthetics should always be met for an excellent treatment outcome.Â
In this article, I will show you the solid technique of capturing records with the Panadent Dento-Facial Analyzer.
3 Level Planes for Capturing Records with Dento-Facial Analyzer
The Panadent Dento-Facial analyzer is based on scientific information that shows that the distance from the incisal edge position of maxillary central incisors to the hinge axis is approximately 100 mm. Most of the population falls in this range so this is the assumption that we are referencing when using this device.
When we mount models, we should have three significant pieces of information, therefore we aim to transfer this information accurately in our model’s information based on these three levels;
- The maxillary positionÂ
- Occlusal plane and incisal plane
- Vertical rod on the dentofacial analyzer
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 sidebar of the Dento-Facial Analyzer should be level to the horizon.
