Mechanical principles associated with removable partial dentures

  1. 1. Removable Partial Dentures by design are intended to be placed into and removed from the mouth.  Because of this they cannot be rigidly connected to the teeth or tissue. This makes them subject to movement in response to functional loads, such as those created by mastication.
  2. 2.  In human body, movement can occur in any of the three fundamental planes which are mutually perpendicular to each other and therefore intersect at right angles.  There are also three axes called the transverse axis, vertical axis and the saggital axis.  Rotation movement of RPD around any of the three axes can occur only within the plane that runs exactly perpendciular to that axis.
  3. 3. Movement occurs in this plane relative to a mediolateral axis that is perpendicular to the saggital plane
  4. 4. Movement in this plane occurs around a vertical axis that is perpendicular to the horizontal plane
  5. 5. Movement in this plane occurs relative to an anteroposterior axis running perpendicular to the frontal plane
