Abfraction Management

Excessive occlusal forces have long been reported to be a significant factor in decreased longevity of dental restorations, including Abfractions. Therefore, after Adhesive Restorative Dentistry, successful treatment requires Occlusal Adjustment Therapy.

How to use the T-Scan III to remove occlusal interferences:

• 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

a. Take a T-Scan excursive force movie and locate lateral interference(s). Enhance patient communication and treatment planning.

b. Use Accufim™ to mark areas of force and adjust.

2. Post-Treatment of interferences in excursion

a. Record a new excursive force movie to verify interference is gone.
b. This stops cyclic compressions onto the CEJ, arresting the abfractive process.
