Abfraction Issues Made Easy with the T-Scan III
| Abfraction lesions are small cracks caused by chewing, clenching or excessive force on teeth. Over time, this force can cause cracks and
splits in the outer layer of the enamel. It has been said that excessive occlusal forces have long been reported to be a significant factor
in decreased longevity of dental restorations, including a potential for Abfraction lesions. Therefore, after Adhesive Restorative Dentistry,
successful treatment requires Occlusal Adjustment Therapy.

How to use the T-Scan III to remove occlusal interferences that may lead to an abfraction issue:
- Simply have the patient bite down on the T-Scan III's thin, high density, disposable
sensor. The resulting Force Movie shows where and for how long the abfracted tooth is
not disengaging from its opposing tooth during excursions (Disclusion Time).
- A Disclusion Time of < .4 seconds insures lateral stresses are removed.

1. Pre-Treatment of interferences in excursion |
 |
 |
 |
1. Take a T-Scan excursive force movie and locate lateral
interference(s). Enhance patient communication and
treatment planning.
|
|
|
|
2. Use Accufilm™ to mark areas of
force and adjust.
|
2. Post-Treatment of interferences in excursion |
 |
 |
 |
3. Record a new excursive force movie to verify
interference is gone.
|
|
|
|
4. This stops cyclic compressions
onto the CEJ, arresting the
abfractive process.
