Easily Grips Tray Material

​The precise tip ends of the Ultra-Trim Scalloping Scissors grip the tray material, which makes trimming even easier.


Tray Fabrication Step by Step

  1. 1

    ​Pour impression with fast-set plaster or dental stone. Pour alginate shortly after making impression to ensure accuracy. Trimming is less work if quantity of stone is kept to a minimum.

  2. 2

    ​For reservoir spaces, apply Ultradent LC Block-Out Resin approximately 0.5mm thick onto the labial surfaces. Stay about 1.5mm from gingival line. Do not extend onto incisal edges or occlusal surfaces.

  3. 3

    ​With vacuum former, heat tray material (Sof-Tray® Classic Sheets) until it sags approximately 1 inch. Adapt plastic over mold. Cool and remove model.

  4. 4

    ​Use Ultradent® Ultra-Trim Scalloping Scissors to precisely trim tray 0.25 to 0.33mm occlusal from gingival margin.

  5. 5

    ​Return tray to model; check tray extensions.

  6. 6

    ​Gently flame polish edges one quadrant at a time.

  7. 7

    ​Finished custom tray, precisely trimmed, is now ready for final adaptation in the patient’s mouth.


  • When trimming the tray, how close should I come to the gingival margin?

    ​Try to leave about a 0.25 to 0.33mm from the gingival margin.

  • Do Ultra-Trim Scalloping Scissors need to be sharpened?

    ​If properly cared for, Ultra-Trim Scalloping Scissors will provide years of satisfactory use. Like any pair of scissors, over time the blades will begin to dull. When that happens, we recommend retiring the old pair and using a new pair, rather than trying to have the blades sharpened.

  • Do I really need special scissors for trimming a whitening tray?

    ​Other scissors may be able to do precise trimming as well, but the Ultra-Trim Scalloping Scissors are specially designed to easily cut through the durable vinyl material with precise detail, in the safest and quickest way possible.
