NAIL POST

Gridwork Relief

Relief wax is placed in edentulous areas 1 mm of relief

Relief Under the Gridwork

Should begin 1.5 - 2 mm from the abutment tooth



3-Proximal minor connector
Shifted slightly lingually Increases rigidity Enhances reciprocation Improves esthetics Often a triangular space below the guiding plane (undercut)


4-surface minor connector -are located on the lingual surface of incisors and canines connector -they connect lingual rests to the major connector
