Flexibility Adds Strength
Today clinicians are prescribing flexible material for removable partial dentures because it makes a better, stronger appliance. Flexible material reduces chair time, eliminates invasive procedures and the cumbersome materials associated with rigid partials. In short, there is no longer any need for metal.
Metal-based RPD design is complex because it has to adapt rigid materials to a flexible environment. This leaves room for error particularly under conditions where ideal designs and clinical preparations are challenged.
In contrast, the material in flexible partials is perfectly suited to the variety of natural conditions in the mouth. It simplifies the design and enables the RPD itself to balance the simultaneous requirements of retention, support and stability.
Flexibility removes many of the unwanted aspects of metal partials. There are fewer steps in the treatment process because preparation of natural teeth is unnecessary. Without the metal frame, the fabrication and try-in processes have also been simplified. In addition, the choice of a flexible partial avoids the placement of metal in your patient's mouth, which allows you to satisfy the patient's interest in metal-free dentistry.
