Intraoral Positioning Devices (IPD)

With a growing number of patients being treated with Intensity Modulated Radiation Therapy each year, there is a need for ever improving positioning devices. One of the key benefits of IMRT is its precise targeting abilities, allowing the separation of beam entry sites and thus the sparing of healthy tissues.

IMRT treatments for head and neck cancer are often performed five days a week for up to six weeks in duration. Each session involves precise planning and a need for highly accurate positioning. This is where our custom IPD’s come into use. We design a unique IPD for each IMRT patient to maximize the protection of healthy tissues and structures, while creating a comfortable position that can be replicated every day of the treatment.

Using the latest in 3D design and manufacturing, we create positioning devices that are not only more comfortable than off- the-shelf pieces currently available, they are also more effective. RadTec Intraoral Positioning Devices represent a breakthrough in 3D manufacturing that allows customized medical devices to be deployed in everyday use for patients around the world.

Every IPD is custom made for the individual, thus maximizing the benefits and comfort of IMRT treatment, while simultaneously improving the quality of life for each patient.


Customized intraoral placement devices:

  • Designed for the patient based on anatomic structure and treatment plan
  • Able to set incisal separation and mandibular position
  • Biocompatible, non-toxic materials
  • Sterilizable

Instructions for deployment of Open Bite Registration Device:

  1. Take physical molds of upper and lower teeth using impression putty, or similar materials • It is suggested to use quick set stone when pouring the models to expedite the final check process. It is also suggested that the final check is done when the patient is still in the office, thus saving another visit should something not work properly
  2. Take the Open Bite stent with the top side up • Denoted with a T on the handle • Make sure the proper incisal opening distance has been chosen
  3. Place the Open Bite Registration Device in the patients mouth and have them open and close their bite until a natural, comfortable position has been found for the positioning of the mandible
  4. Using blue mouse or other injectable molding material, inject mouse along the top and bottom of each arm • pushing from front to back while applying slight pressure to allow mouse to work between the teeth and registration arms
  5. Allow mouse to cure as recommended by manufacturer
  6. Once mouse is set have patient open their bite and remove the Open Bite Registration Device
  7. Place the upper and lower molds onto the Open Bite Registration Device and insure a proper fit was achieved
  8. Once complete determine what method will be used to transfer device and molds to: RadTec Medical Devices Inc. 170 Glenn Way Suite #5 San Carlos, CA 94070

Instructions for deployment of finished IPD:

  1. Sterilize device.
    • Inspect for cracks or other defects. If defects are found take note and contact RadTec Medical Devices immediately for a replacement IPD.
  2. Once inspected, give the sterilized IPD to the patient and have them place the device in their mouth, fitting both upper and lower teeth into the appropriate positions
  3. Make sure the tongue is positioned, as needed, and inspect fitment.
  4. Fitment of the positioning mask should leave enough room for the IPD handle without putting pressure on the IPD.
    • Leave enough room around handle, so that when the mask cools there isn’t pressure pushing down in the IPD as this will cause discomfort and difficulty with positioning.
  5. Have the patient verify that the position is comfortable and they are able to maintain this position during treatment.
    • Tips for ease of use:
    • Instruct the patient to breathe through their nose, not mouth.
    • Try to minimize swallowing with IPD in place (suction may be applied if available).
    • Other means of sedation may be used for patients presenting continued difficulty of use.
  6. Once treatment session is complete, remove mask and IPD.
  7. Rinse the IPD in clean water and dry before placing in storage container.
  8. Storage:
    • Store in cool dry area.
    • Keep IPD in proper storage container for product safety.
    • Do Not Drop IPD.
    • Do not expose to excessive heat or intense light.
    • Handle and store in manor that maintains proper sterilization.
    • If any questions arise contact RadTec Medical Devices immediately at 1(844)Rad-Tec1 or email

*Fitment may only be adjusted by trained personnel and must be documented.

  • Minor adjustments such as smoothing or rounding of corners and edges may be performed using lite sand paper or files.
  • Do not use power tools to make adjustments.
  • Do not apply excessive heat.
  • Do not cut.
  • Any modifications void all warranties written or implied.
