Can Occlusal Adjustment Cure TMD? ‘DTR’ and T Scan Experience – PDP255

1 hour 2 minutes

Are posterior tooth contacts really harmless?

Could group function and non-working side interferences be driving muscular TMD, headaches, and facial pain?

And can digital occlusal data change how we approach bite adjustment?

Dr. Jeremy Bliss joins the podcast to tackle one of the most controversial topics in dentistry: Selective Grinding/Equilibration for TMD but specifically Disclusion Time Reduction (DTR). With a strong focus on restorative technology, lasers, and T-Scan analysis, Jeremy brings a practical and experience-driven perspective to occlusion and bite therapy.

This episode breaks DTR down from the very beginning—what it is, how it differs from traditional equilibration, and why reducing posterior tooth contact during excursive movements may help certain susceptible patients. The conversation also explores canine guidance vs group function, macro vs micro occlusion, and where DTR fits within evidence-based dentistry when conservative care has failed.

Protrusive Dental Pearl: Don’t buy advanced occlusal or motion-tracking tech unless your type of dentistry, training, lab support, and local backup can fully use the data—otherwise it’s just a Ferrari stuck in traffic.

Key Takeaways: Disclusion Time Reduction (DTR) & T-Scan

T-Scan: Provides objective data on tooth contact timing and force—impossible to see with the eye or articulating paper.

EMG: Tracks temporalis and masseter activity to show how muscles respond to occlusion.

Goal of DTR: Reduce posterior tooth contact during excursions, shifting contact to canines to relax muscles.

Patient Selection: Best for symptomatic muscular TMD; requires sufficient canine/incisal overlap.

Clinical Benefits: Reduces headaches, migraines, muscle tension, parafunctional damage, and progressive tooth wear.

Procedure: Conservative enamel adjustments (0.5–0.75 mm), guided by T-Scan; posterior teeth should disclude in <0.5 sec.

Implant Care: Prevent early loading to protect bone and restorations.

Evidence: Supported by systematic review and clinical cases; improves outcomes over traditional occlusal adjustments.
