Digital Bite Analysis at Lawrence Park Dental

Digital bite analysis, also known as DTR exam (Disclusion Time Reduction) in conjunction with new technologies (Tek-scan in tandem with and EMG link) allows the dentist to identify bite discrepancies by measuring the muscle activity and tooth contacts profile in a dynamic manner.

Using Tek-scan to perform DTR exam 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

Prolonged muscles contraction (bruxism or clenching) will lead to overload and premature breakdown of the chewing system (occlusal disease).

Occlusal disease is destructive and progressive.

Untreated occlusal disease can lead to:

  • TMJ disease (TMD).
  • Tooth fracture
  • Vertical root fracture/premature tooth loss
  • Excessive bone loss
  • Muscle soreness
  • Muscle fatigue (cannot chew gum/eat steak)
  • Headaches

DTR Therapy will decrease rate of breakdown and improved chewing efficiency. Muscle physiology will change and adapt to the new bite arrangement.

Areas of excessive enamel wear may require restorative treatment to seal exposed tooth structure.

Hyperactive muscles will heal and adapt to lower force output in 80-85% of patients – less forces upon the chewing system.

How Does Digital Bite Analysis and DTR Therapy Work?

DTR relies on T-Scan and EMG technologies to help dentists fully understand the problem. It’s then followed by adjustment procedures to fix the tricky areas and provide a better bite. This may involve a reduction in the enamel, or composite additions on maxillary canine teeth. Further bite analyses are performed post-treatment and new corrections are made as needed.


During the exam at Lawrence Park Dental in North York, Dr. Queiroz will use the T-Scan and EMG technologies to analyze your bite force, location, and timing.

What to expect during the first bite analysis consultation?

  1. Place adhesive electrodes in your face and neck.
  2. You bite the sensor.
  3. The computer software renders the information as 3D data on the screen.
  4. Dr. Queiroz can then check the data in real time and identify the areas responsible for bite discrepancies.
  5. More than seeing the actual contact between the teeth, Dr. Queiroz can determine the impact of your bite on your gums and jaw and recommend the optimal treatment.
