While the typical bleaching tray fabrication is well described, sometimes there are situations for which either different tray fabrication options or different impression techniques may serve the patient and the practice better. For some patients, a typical alginate impressions may not be desirable, so thermoplastic trays may be indicated for children, orthodontic patients, and high caries patients.

Learning Objectives: 

1. Understand bleaching vs. whitening.

2. Review general bleaching principles.

3. Learn Carbamide and hydrogen peroxide differences.

4. Discuss different types of novel bleaching tray fabrication technique other than conventional, including thermoplastic trays and impression techniques.
