TCS Partials

tcs logoThe tcs® Unbreakable RPDs are thin, flexible, lightweight, and extremely comfortable. Doctors and patients enjoy the unparalleled simplicity, comfort and aesthetics. Today, more and more dental practitioners are relying on nylon-based removable partial dentures for their patients. Acrylic denture bases are hard and they can break. In addition, partials that contain metal clasps can be unsightly, causing many patients to feel self-conscious about the way they look. Partials utilizing cast clasps are becoming increasingly undesirable to patients who want to limit the amount of metal in their mouth.

As chosen by the readers of Dentistry Today, our tcs® partial has been selected as a Top 100 product for 2014.

Why choose a tcs® partial?

  • tcs® Unbreakable material is manufactured in the U.S.A. from the highest quality materials.
  • Unbreakable: Replacing or repairing broken partials is expensive and inconvenient. Patients have to be without their partials while they're waiting for them to be repaired. A tcs® partial won't break if it is dropped or mishandled. Please remember, however, that the resin teeth are still breakable.
  • Lightweight and Comfortable: Patients get used to them quickly and soon forget they're wearing them!
  • Aesthetic: tcs® Unbreakable blends naturally with the surrounding tissue and gums. In fact, they're practically invisible. Younger patients will appreciate the natural look of tcs® Unbreakable. Our strict quality control means they don't vary in shade, you can always count on consistent color.
  • Biocompatible: tcs® Unbreakable RPDs are biocompatible, making them ideal for patients who are allergic to monomers.


Instertion Technique

  • The Hot Water Treatment is very important as it allows for a smooth initial insertion and a good adaptation with your patients natural tissues.
  • Submerge the tcs® Unbreakable restoration in very hot tap water for approximately one minute.
  • When the partials cools to a tolerable temperature, gently insert it into the patients mouth.


Adjustment technique

  • If the patient senses discomfort due to tightness of the clasp, the clasp may be loosened slightly by submerging that part in hot water for approx 30 seconds, removing it and gently bending the clasp outward while holding it underneath running cold tap water.
  • The clasp can also be tightened by following the same procedure but bending the clasp inward.
  • If further adjustments are needed, they can be made easily with the proper tools and techniques. If patient feels persistent irritation, reduction of the partial may be necessary.
  • There are a variety of burs that are specifically designed for thermoplastic materials. Specifically, the following carbide burs 50C25-01 50C79-01 50G79-01, 50251G-01 and the green mounted point 4501-01. These can be purchased directly from Thermoplastic Comfort Systems, Inc.
  • Set your handpiece on a low speed and use fast, light scraping back and forth movements to reduce area. Do not keep bur in one spot, be sure to keep it in constant motion. Do not use too much pressure as this may burn or distort the restoration.
  • Rubber Wheels or Points are ideal for making small adjustments and/or smoothing after adjustments have been made. Usually the brown rubber wheel/point will leave the case smooth and shiny and it will not be necessary to re-polish. These are part numbers 4503-01, 4510-01 and 4511-01 and can also be purchased from Thermoplastic Comfort Systems, Inc.
  • If there are any threads remaining, these can be removed with a sharp blade



Proper Care of tcs® Unbreakable Appliances

tcs® Unbreakable partials are fabricated from a strong biocompatible nylon thermoplastic. They are very easy to care for. In order to keep your restoration looking and feeling like new, please have your patients follow these simple recommendations:

  • Continue to brush your natural teeth and gums as directed by your dentist.
  • Clean your restoration daily. Simply rinse your restoration under warm running water for approximately 30 seconds to one minute in order to remove any food particles prior to soaking it in the denture cleaner.
  • With a very soft denture brush, brush your restoration using water only. Rinse again.
  • Place your restoration in tcs® Concentrated Denture Cleaner for at least 30 minutes per day.
  • Keep your restoration in water or tcs® Concentrated Denture Cleaner when you are not wearing it.
  • DO NOT use bleach, toothpaste or similar cleaning products as these may scratch the surface of your restoration.
  • Please remember that although tcs® is unbreakable, the teeth are not. Please handle your partial with care.
  • The cleaner can be purchased directly from the company by visiting

When a tcs® partial requires a reline, it is usually jumped to a new base (rebase). To have us add a tooth, reline, or rebase the partial, please follow the following steps.

  • A wash impression is taken inside the partial using light body PVS material. Be sure to use a light coating of adhesive inside the partial.
  • Before you insert the partial into the mouth for the wash impression, inject a small amount of impression material around the buccal of the teeth that are clasped. This will ensure that the undercut areas are captured
  • When the wash impression is made, the patient closes his/her mouth gently to ensure the partial if fully seated and the occlusion is accurate, as the PVS material is setting.
  • Once the PVS material has set, an impression is taken inside a tray and the impression is removed from the mouth with the partial and the wash material reline in place.
  • Carefully examine the partial to assure that it is positioned correctly and did not unseat when the pick up impression was made.
  • Send the pick up impression with wash reline inside the partial to us for rebase or reline.
  • If you use alginate material for the pick up impression of the partial and PVS wash/reline impression, then you must pour the impression before sending it to us.
