A most common clinical situation is presented with missing first premolar and first molar, resulting in FPD design in which the canine and the second molar act as terminal abutments and second premolar act as a pier abutment. In such case there is a tendency of terminal abutments to intrude during function results in a teetering movement, where the pier abutment act as a fulcrum. These movements will eventually lead to debonding of less retentive terminal retainer. An appropriate means of causing a stress breaking action is by use of a precision attachment (ten on-mortise) for adequate dissipation of forces along the long axis of the tooth and not in any other direction. The present case report describes incorporation of precision attachment to rehabilitate pier abutment in 5-unit FPD.
