Abstract :
A pier abutment is the lone standing abutment tooth between two critically situated edentulous spaces, in a frequently seen clinical situation, a missing first premolar and first molar is seen, which leads to a design where canine and the second molar acts as a terminal abutments and second premolar acts as a pier abutment. This pier abutment acts as a fulcrum which may lead to debonding of the less retentive terminal abutment during function, to overcome this situation a non rigid connector is advised. This paper presents a clinical case report which describes the incorporation of non rigid connector to rehabilitate the pier abutment case in unilateral maxillary and mandibular region.
