Selecting an occlusal plate, whether for the upper or lower arch, is an important decision. It should not be taken lightly, because it directly influences the effectiveness of the treatment, the patient's comfort, as well as their overall satisfaction. In this article, we will explore seven key criteria that should guide this decision, providing practical insight based on the latest research and advanced occlusion training by Dr. Alain Aubé of the Canadian Occlusion Institute.
7 Criteria for selecting an occlusal plate
1. Mobile teeth
Tooth mobility provides an early indicator of where to place plaque. If an arch has mobile teeth, it is preferable to apply the occlusal plate there. In cases where both arches show mobility, consider the use of double plates to distribute the occlusal load and stabilize the situation. See the article: When to give a double plate to your patients?
2. Angle class
The Angle of Occlusion classification strongly influences the choice of the arch on which to place the plate:
- Class I : No specific preference, high or low may be suitable.
- Strong Class II : Favor the top to avoid problems related to overhang and comfort of the lower lip.
- Strong Class III : Go for the low for the same reasons reversed.
3. Mandibular mobility
High mandibular mobility, particularly in protrusion, may require adaptation of the plate downwards, especially in the presence of a strong Class II. This approach helps support a stable occlusion while accommodating extreme mandibular movements.
4. Availability of canines
The canines play a pivotal role in occlusal guidance. Their availability, eruption, and position must be evaluated to determine the arch of choice. An arch without available canines is ideally the one that will receive the plate. If no canine is available, see the article: When to give a double plate to your patients?
5. Sleep Apnea
Patients suffering from or at risk of suffering from sleep apnea should be treated with caution, in accordance with the practices established by Dr. Aubé during his training. An upper occlusal plate can exacerbate this condition, making the lower plate often more suitable.
6. The arch with the most teeth
The arch with the greatest number of teeth should ideally receive the occlusal plate for better stability and distribution of occlusal force. If no arch is suitable for receiving an Aubé™ plate, see the article: When to give a double plate to your patients?
7. The patient's choice
Finally, while taking into account technical criteria, patient choice and preferences should be respected when possible without compromising treatment results.
Conclusion
Selection of an occlusal plate requires careful evaluation of several key factors to ensure treatment success. By integrating the criteria of tooth mobility, angle class, mandibular mobility, availability of canines, risk of sleep apnea, quantity of teeth, and patient preference, professionals can optimize results for their patients.
