Disclusion Time Reduction (DTR) Therapy

Disclusion Time Reduction (DTR) Therapy

Disclusion Time Reduction (DTR) Therapy is a specialized dental treatment procedure that requires the use of T-Scan in tandem with an EMG link to evaluate occlusal forces in relation to muscle activity.

Now with our latest foray into the DTR and T-Scan, I am seeing some of the mistakes I have made in the past, some of the assumptions that were wrong. With this technology, we are helping people that we haven't been able to help before.

DTR therapy involves using objective data from tooth pressure and jaw muscles to make tiny adjustments in bite force. This will attempt to alleviate symptoms and pain from headaches or TMD.

Using T-Scan™ in DTR Therapy

DTR Therapy uses T-Scan™ digital occlusal analysis data to measure the impact of excursive movements on the occlusal plane. The goal is to identify contacts that may be overly engaging during excursive movements, a problem that can lead to hyperactive muscles, breakage, and TMD symptoms. The clinician evaluates the time it takes for posterior teeth to disengage during excursive movements and correlates the occlusal data to muscle activity in real time.

Using T-Scan's bite force and timing data to perform DTR Therapy allows the clinician to:

  • Identify overly engaged contacts during excursive movements
  • Evaluate how muscles are firing during bite cycles
  • Verify occlusal contacts that could be contributing to TMD symptoms
  • Use data to guide adjustment procedures
  • Objectively analyze the timing of disclusion

Finding a DTR Dentist

A T-Scan is required for Disclusion Time Reduction therapy, but not all T-Scan dentists perform this therapy and have the full EMG integration.
