Laboratory light-curing units are bench-mounted UV or LED curing systems used to polymerize light-cure resins, sealants, and coatings applied during laboratory fabrication, such as denture base repairs, temporary crown materials, and light-cure orthodontic resins. Compared to handheld clinical curing lights, laboratory units typically offer larger curing chambers and multi-directional light exposure to ensure uniform cure across a full appliance or prosthesis. This category supports laboratory workflows that rely on light-cure rather than heat-cure or self-cure materials, offering faster turnaround for provisional and repair work.
