Partial dentures are designed to replace missing dentition and prevent healthy dentition from migrating due to a loss of approximating or opposing teeth.
The general objective with partial dentures is to prevent problems which might occur if teeth migrate out of their natural dimension and position. Various problems can arise due to migrating dentition, bite problems, such as temporomandibular Joint (TMJ) problems can create headaches, ear aches, or even difficulty moving the jaw due to extreme pain. These issues can sometimes be initially identified by a clicking or popping sound.
Generally, partial dentures have appropriately placed retaining clasps, these can be made of flexible metal or alternatively from flexible and colour assimilated material for aesthetic purposes. Partial dentures can be constructed in a combination of metal and acrylic, or purely out of the diverse acrylic available.
When treating patients with sensitive mouths or other oral health considerations, flexible dentures may be found to be more tolerable since they mould and bend over and around the dentition.
