The lone standing abutment: A case report
Journal Title: International Journal of Applied Dental Sciences - Year 2016, Vol 2, Issue 1
Abstract
Pier abutment is characterized by a lone standing abutment with edentulous regions on either side of it. The goal of this case report is to discuss the use of key and keyway, a type of non-rigid connector to rehabilitate a patient with a pier abutment situation. Following radiographic evaluation of the abutment teeth, tooth preparation was done and the key and key way were fabricated in the prosthesis in such a way that the keyway was placed on the mesial side and the key on the distal side of the retainer or pontic. Rehabilitating a patient with a key and key way type of non-rigid connector is an ideal and recommended option when a patient presents with a pier abutment situation.
