Bleaching Tray Fabrication

Bleaching tray fabrication

A bleaching tray is a clear, custom-fitted dental retainer that applies the whitening gel to your teeth while you wear it, and holds it against your teeth for at-home treatment. Custom trays are much more comfortable as they are designed to give a snug fit, and you will also achieve better results with a custom whitening tray as less gel is lost through spillage and gum irritation, which is typical with store bought trays.

Step-by-Step procedure for fabricating bleaching tray

Patient Assessment

• Examine the mouth and determine cause of stain.
• Treat decay, leaking restorations, or gum infection prior to bleach.

Prepare the Cast

Create Reservoirs (Optional)

• Apply a thin coat (about 0.5 mm) of light-cured block-out resin or tray spacer on the facial surfaces of the teeth you will be bleaching.
• Stop the spacer 1 mm short of the gingival margin.
• Some practitioners elect not to use reservoirs based on evidence that suggest no difference in whitening results with or without them.

Vacuum Form the Tray

• Place the stone model on the vacuum-forming device.
• Heat the thermoplastic sheet until it softens.
• Using vacuum pressure, form the sheet over the mold.
• Let stand until cool.

Trim the Tray

• Remove the tray from the mold it was formed on.
• Trim it about 0.5 to 1 mm above the gingival margin or scalloped the tray to trail the gingival contour.
• All edges should be rounded off for comfort.

Test the Fit

FAQ

How long does it take to do a bleach tray? 

• The production process is usually 30–60 minutes in the dental lab, but the dental office may require one or two visits to complete the entire procedure based on its workflow.

Should I wear the bleaching tray for how many hours? 

• The amount of time you should wear it depends on the whitening gel's type and concentration. Some gels are worn for 30-60 minutes and some for the whole night. Follow your dentist's advice always.

Are bleaching trays reusable? 

• Yes. Custom bleaching trays are intended to be reused for future whitening touch-ups, if they are cleaned correctly and stored in a protective case.

Is it safe for my teeth to be sensitive while I use bleaching trays? 

• Some people will feel temporary sensitivity in their teeth and mild gum irritation when whitening. Such effects are typically short-lived and can be mitigated by decreasing the amount of time the bleaching tray is worn, or by using a lower-strength bleaching gel.

Do I need reservoirs in a bleaching tray? 

• Not necessarily. Although reservoirs provide additional space for the bleaching gel, a lot of contemporary bleaching trays do not have reservoirs and still deliver excellent whitening outcome using less gel.

How to Clean & Store a Whitening Tray? 

• After each use rinse the tray with cool water, if necessary, gently brush the tray with a soft-bristled toothbrush and allow the tray to dry naturally before placing in your case. Do not use hot water, as this can warp the tray.
