Effectiveness of Dental Bleaching Using Different Designs of 3D-Printed and Conventional Customized Nightguards
Sponsor: Universitat Internacional de Catalunya
Summary
This randomized, double-blind, split-mouth clinical trial evaluates the effectiveness of at-home dental bleaching using customized nightguards fabricated by digital (3D-printed CAD-CAM) and conventional methods, with and without reservoirs. Adult participants with good general and oral health and a baseline tooth shade of A2 or darker undergo bleaching with 10% carbamide peroxide. Outcomes include tooth color change (subjective and spectrophotometric measures), tooth sensitivity, gingival irritation, patient comfort, and patient satisfaction over time.

Conditions
Interventions
Customized bleaching tray fabrication
Customized bleaching trays were fabricated using either a conventional vacuum-forming technique or a digital CAD-CAM 3D-printing technique, according to randomized allocation within a split-mouth design.
Reservoir tray design
Tray designs were prepared either with a reservoir or without a reservoir, according to randomized allocation across hemiarches within the split-mouth design.
Carbamide peroxide 10%
At-home bleaching gel containing 10% carbamide peroxide applied in customized trays according to the study protocol
