Question: 1 / 400

What type of custom tray would be made for a vital bleaching procedure?

Silicone resin

thermoplastic resin

A silicone resin custom tray would not be used for a vital bleaching procedure as it is not able to withstand the high temperatures involved and may distort in shape. Acrylic resin is not recommended as it can be porous and absorb bleaching agents, causing them to be less effective. Metal trays are also not ideal as they may cause uneven distribution of the bleaching agent and can potentially cause irritation to the patient's gum tissue. The best option for a custom tray for a vital bleaching procedure is a thermoplastic resin as it is able to withstand the high temperatures and provides a snug fit for the bleaching agent to effectively whiten the teeth.
