Do your patients really have two bites?
Does their bite change when they lie down? When they sleep?
And how can you explain centric relation, posture, and deprogramming in a way that patients actually understand?
Dr. Bobby Supple joins Jaz for a powerful episode unpacking one of the most misunderstood topics in occlusion: the daytime chewing bite versus the nighttime airway bite. After spending days with Bobby in his New Mexico clinic, Jaz saw firsthand how simply and elegantly Bobby communicates concepts that usually leave patients — and dentists — confused.
Together, they explore why bite discrepancies exist, what happens when the condyles fully seat, and how aligning Bite One and Bite Two over time can transform patient comfort and restorative outcomes.
Protrusive Dental Pearl
- When assessing abfractions, always check the patient’s bite in two positions: seated upright and lying back.
- Posture subtly shifts the condylar position and can change how forces load the tooth.

Key Takeaways:
- Every patient has two bites — their upright chewing bite and their horizontal airway bite.
- Posture changes the condylar position more than we realise.
- Clear communication can make complex occlusion concepts instantly understandable.
- Aligning Bite One and Bite Two over time leads to healthier joints and more predictable dentistry.

AGD Subject Code: 180 OCCLUSION
Aim: To enhance clinicians’ understanding of the “two bites” concept, the role of condylar position in occlusal health, the use of T-Scan in diagnosing occlusal force patterns, and the long-term prevention-based approach to managing occlusal stress, abfractions, and TMJ remodeling.
Dentists will be able to –
- Explain the concept of patients having “two bites” (MIP bite vs. airway/postural bite) and describe how posture influences mandibular position.
- Identify occlusal stress patterns using clinical examination and digital tools (e.g., T-Scan) to recognise overloads that may contribute to abfractions, cracks, or TMJ symptoms.
- Apply a long-term, preventive approach to occlusal management that aims to harmonise daytime and nighttime bites while supporting joint remodeling through appropriate orthotic therapy.
