Non-rigid connector: The wand to allay the stresses on abutment

Saurav Banerjee et al. Contemp Clin Dent. 2011 Oct.

Abstract

The use of rigid connectors in 5-unit fixed dental prosthesis with a pier abutment can result in failure of weaker retainer in the long run as the pier abutment acts as a fulcrum. Non-rigid connector placed on the distal aspect of pier seems to reduce potentially excess stress concentration on the pier abutment.

Keywords: Matrix; non-rigid connectors; patrix; pier.
