A structurally strong restorative system.
Spirapost consists of surgical stainless steel wires twisted around biocompatible natural color polyfiber strands.
The polyfiber strands work similarly to rebar-type construction in the building industry. The resin cement (within the canal) and composite core material integrate with the strands, creating a homogenous unit that effectively and safely adds reinforcement and structural integrity to the final restoration. It does not hold memory, so there is no concern for undue stresses within the canal.
This strong structure facilitates the safe absorption and distribution of external forces and virtually eliminates the risk of failure due to flexibility discrepancies between the post and restorative material.
