The radicular post. Specifications

The radicular pivot, the key component in Richmond and Davis crowns, was initially devised to maintain a permanent link between an artificial crown and the residual root of a monoradicular tooth. The success of such structures depends on three parameters: pivot rigidity (to prevent its fracture or deformation), rigidity of the link of between pivot and artificial crown, permanence of the cemented junction between pivot and root (pivot retentivity).
