TCS Removable Dental Appliances

TCS thermoplastic resins are manufactured from the highest quality materials and under a strict quality management system that meets ISO 13485:2003 and NS-EN ISO 13485:2012 requirements

An aesthetic solution for missing teeth without the cost associated with crown/bridge or implants. Additionally, TCS flexible partials are very popular as a transitional appliance during the healing period for implants.


Lightweight and Comfortable
TCS resins have properties that allow partials to be fabricated very thin without compromising durability, making them very comfortable for the patient.
TCS restorations are manufactured to blend naturally with the surrounding tissue and gums. A well designed and fabricated TCS
appliance will be unnoticeable in the patient’s mouth.
TCS restorations are biocompatible, and ideal for patients that are allergic to monomers found in acrylic dentures.
TCS flexible partials offer the ideal degree of flexibility, and patients find the adjustment period much smoother when compared to conventional partial dentures.
Unlike permanent tooth replacement options, such as crown/bridge and implants, TCS partials are non-invasive, making them ideal for patients with a low threshold for pain and/or the very elderly. The unique characteristics of TCS partials utilize the tissue undercuts and portions of abutment teeth for retention.

General Techniques for TCS Flexible Partials

Preparation for Adding Teeth

The laboratory will utilize either a welding technique or an injection technique.
• Be sure the partial is free of any pastes or adhesives before taking the impression.
• An alginate impression is taken with the partial in the mouth.
• Remove the impression from the mouth with the partial in the impression.
• Be sure the partial is fully seated in the impression material.
• Immediately pour the model with regular yellow stone.
• Forward to the laboratory with instructions.

Preparation for Rebase

The laboratory will register the position of the teeth with a plaster matrix and remove the base. A new base will be waxed up and reprocessed using the existing teeth.
In most cases where an overall rebase is needed, the case
is jumped into a new base.
• A rubber base impression is taken under the TCS partial in a closed-mouth condition.
• The patient closes his/her mouth gently to ensure correct occlusion as the rubber base is setting.
• Once the rubber base material has set, an alginate impression is taken and the impression is removed from the mouth with the partial and the rubber base in place.
• Carefully examine the partial to assure that it is positioned correctly in the alginate material.
• Immediately pour the model with regular yellow stone.
• DO NOT separate the partial from the stone model.
• Forward to the laboratory with instructions.

Impression Techniques

One of the many benefits of TCS restorations is that little-to no tooth preparation is needed. The laboratory only needs a good alginate impression (poured promptly), a counter model and the bite registration.
TCS recommends a lightweight alginate material for impression taking, however, irreversible hydrocolloid, polyvinyl siloxane and polyether impressions are also suitable.
• An accurate impression is the first step and is key to the success of a TCS partial. If an alginate impression is taken,
promptly pour it up using lab stone. Then take a counter-impression and a bite registration.
• Examine the impression. The impression should have all the anatomical details for a successful TCS partial. Also check for voids and air bubbles.

Proper care

TCS appliances are very easy to care for. In order to keep them looking and feeling like new, please have your patients follow these simple recommendations:
• Continue to brush natural teeth and gums as directed
• Clean the appliance daily. Rinse under warm running water forapproximately 10-30 seconds to remove any food particles.
• Brush appliance with a soft denture brush using water only. Rinse again.
• Place appliance in a denture cleaner for at least 15 minutes daily.
We recommend TCS Concentrated Dental Appliance Cleaner.
• When possible, keep appliance in water or a denture solution when not wearing it.
DO NOT use bleach, toothpaste, or similar cleaning products, these may scratch or discolor the surface of the appliance.
