Create Custom Sensitivity Trays

Provide your patients with custom sensitivity trays to quickly treat sensitivity exactly where it occurs. Load with UltraEZ or Flor-Opal gel to relieve tooth discomfort caused by root sensitivity, thermal and chemical changes, periodontal conditions, bleaching, crown and/or bridge work, toothbrush abrasion, etc.

SENSITIVITY TRAY FABRICATION

1. Pour, trim, block out
Pour and trim cast as you would for a standard bleaching tray. Apply 0.5-1.0mm of Ultradent LC Block-Out Resin to a clean, dry cast on areas in which patient is experiencing sensitivity. Also apply resin to areas where there are open embrasures, etc. For periodontal patients, clinician may determine that pre-operative impressions are indicated. In such cases, reservoir spacing will be created post-op because of recontoured and apically positioned gingiva.

2. Cure block out
Cure LC Block-Out for ~2 minutes in light curing unit/box. A hand-held intraoral light can be used instead, with a curing time of 20-40 seconds per tooth. (Alternatively, try VALO at 10-20 seconds per tooth.) Wipe off oxygen inhibition layer.

3. Vacuum form
With vacuum former (UltraVac), heat a Sof-Tray 0.035” sheet until it sags ~1 inch. Activate vacuum and adapt softened plastic over mold. Cool and remove model.

4. Trim
Cut excess bulk of material away with serrated plastic trimmers. Trim excess tray material, allowing 4-6mm to overlap onto gingival tissue. Contour tray margin to avoid anatomical structures such as frenum attachments, tori, etc.

5. Flame polish and adapt
Return tray to model; check tray extensions. Gently flame polish edges, one quadrant at a time. While still warm, hold periphery of each segment firmly against model for three seconds with water-moistened finger. If an area is short of the desired length, gently heat and push tray material to the desired location. If this thins the material too much, a new tray should be fabricated.

Block out sensitive areas.
Block out areas where patient is experiencing sensitivity.

Deliver desensitizing gel into custom tray.
Deliver a desensitizing gel like UltraEZ or Flor-Opal into sensitivity tray. Recommended wear time depends on the patient and condition. With UltraEZ, average treatment times range from 15 minutes to one hour. With Flor-Opal, 2 to 8 hours is typical.

Flor-Opal sustained release fluoride gel.
Flor-Opal® is a unique, sustained-release, 0.5% fluoride ion in a sticky, viscous gel with a pH of ~6.5.

UltraEZ potassium nitrate and fluoride gel
UltraEZ is a unique, sustained release, 3% potassium nitrate and 0.11% weight by weight fluoride ion, sticky, viscous gel.
