Clinical Indications

  • Flexible and easier to insert
  • Design versatility for a patient does not want metal clasps to show
  • Short term/transitional tooth replacement (implant healing or extraction site healing)
  • Patients with metal sensitivity
  • Acrylic Allergies
  • History of partial frame breakage
  • Cost concerns (flexible partials are much less expensive to fabricate)
  • Compromised abutment teeth
  • Patients demanding a more comfortable and lighter fit
  • Alternative to implants or fixed products
  • Presence of tori
Back To Top


  • Need for more rigid appliance due to poor soft tissue support or few remaining teeth
  • Quality of teeth is too poor to support DuraFlex
  • Minimal vertical clearance, less than 3mm
  • Flat ridge
  • Immediate applications
  • Should not be used with patients with
    • poor oral hygiene,
    • very short or heavily worn lower anteriors,
    • over a closed vertical dimension or
    • protruding tori.
  • When there is minimal undercut on abutment teeth, metal clasp will be recommended.
  • Artistic Dental Laboratories can rebase, repair and add teeth to DuraFlex.

Case Planning for Duraflex Flexible Partials

  • Unlike acrylic dentures, there is no chemical bond between acrylic teeth and flexible partial material.
  • The denture must be surrounded by flexible partial material, therefore, teeth cannot be ridge tapped or abutted to the ridge.
  • The teeth are drilled to create mechanical retention.
  • It is necessary to have 5mm vertical space to achieve the proper mechanical retention of the denture teeth, any less and the teeth will fail.
  • The flexible material is nearly unbreakable, but the teeth WILL fail fromover reduction and lack of clearance.

Preparation Requirements

  • One of the many benefits of thermoplastic partials is that little to no tooth preparation is needed.
  • Artistic Dental Laboratories requires only a master and an opposing model.
  • A custom tray is normally not necessary.
  • For precise fit and minimal adjustments we highly recommend an alginate impression be used. Alginate impression material will record the tissue at rest instead of under load and result in a better fitting flexible partial.
  • Please send an
    • Opposing model
    • Bite registration, and,
    • Tooth shade (see below)
  • Flexible partials are tissue born and free movement stresses the abutments.
  • Flexible partial denture bases typically flex towards the center of the mouth. This can create undue stress on abutments. To eliminate this, follow these guidelines:
    • Lower arches with few abutments, e.g., 22, 27, and/or extremely resorbed ridges should incorporate a metal substructure to keep the partial more rigid.
    • Tall isolated teeth and teeth with large degrees of undercut to the buccal should be avoided as abutments when possible.
Tooth Shade
Duraflex comes in these shades
  • Tissue tone pink (standard) produced to remain translucent after processing
  • Meharry tone
  • Medium blend

  • Adjustments with Duraflex are cleaner than nylon thermoplastics so there is no gumming of your instruments.
  • Use a rubber wheel lightly for adjustments.
  • Polishing can be accomplished with a 50% coarse / 50% fine pumice mixture using a rag wheel only (no brush wheels).
  • For a high shine, simply use a rag wheel and lightly buff denture (on a slow lathe speed) using Tripoli buffing compound.

If the patient senses discomfort due to tightness of the clasp, the clasp may be loosened slightly by submerging in hot water for approximately 30 seconds, removing it and gently bending the clasp outward while holding it underneath cold running tap water.

Following the same procedure but bending the clasp inward can also tighten the clasp.

If there is a need for adjustment when trying the partial in the patient‘s mouth, the thermoplastic must be handled differently than an acrylic material.

It is best to use carbide burs when adjusting the flexible partials. We recommend fine stone and rubber points for most adjustments and a coral stone for areas that require more material to be removed.
  • Set your hand piece on a low speed and use fast, light scraping back and forth movements to reduce area.
  • Do not keep bur in one place, be sure to keep the bur in constant motion.
  • Do not use too much pressure as this may burn or distort restoration.
  • If there are any threads remaining, remove them with a sharp blade.
Preparation for adding a tooth
  • A pick-up impression must be used. It is essential to remove all pastes or adhesives from the tissue-surface of the partial before taking the impression.
  • With the partial in place in the mouth, take an alginate impression.
  • Remove the impression with the partial in the impression. Be sure the partial is fully seated in the impression material.
  • Pour the model promptly.
  • DO NOT separate the partial from the stone model.
  • Ship the materials to Artistic Dental Laboratory, Inc., with instructions to add the missing tooth, teeth and retention.
Preparation for a Rebase
  • In most cases, when an overall rebase is needed, the case is jumped to a new base. A rubber base impression is taken under the partial in a closed-mouth condition.
  • The patient closes his/her mouth gently to ensure a 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.
  • It is advisable to also take a new fully edentulous alginate impression of the arch to facilitate the rebase.
  • Ship the materials to Artistic Dental Laboratory, Inc., with instructions.
Patient care of the partial
  • We recommend the patient soaks and rinses their partial daily to keep it clean.
  • Abrasive toothpastes may be harmful to your partial. (Most toothpaste indicates whether or not they are abrasive.)
  • We recommend TCS® Concentrated Denture Cleaner to clean your patient‘s partial.

Patient Delivery

Prior to the first insertion, soak the partial in hot water (not boiling) for one (1) minute to soften the material and ease the insertion process. The Hot Water Treatment is very important as it allows for a smooth initial insertion and a good adaption with your patient‘s natural tissues. When the partial cools to a tolerable temperature, gently insert it into the patient‘s mouth. Back To Top
