INFRABULGE- COMES FROM BELOW THE BULGE
 I bar
 T bar
 Modified T bar
 Y bar

Bar clasp (Gingivaly approaching clasp/ infrabulge)
 Anterior canines in maxillary
 Aesthetic situations
 Most retentive
 Because canines have very less undercuts.
 Contraindication
o When there is not enough vestibular depth
o When there is undercut in that area – coz it will engage there while removal, and traumatize the tissue, hurt the patient
