PARTS OF CLASPRetentive Arm- Retention*a. Orginates from the occlusal third and terminates in the cervical thirdb. Placed on the buccal aspectc. The retentive terminal engages the undercut – ie apical to the highest point of contour / the survey line.d. Rest of the clasp has to be above the hight of contour.e. It has tapering thickness when you talk about shapef. It has to be sated passively, ie no force when already seated, and be only active or provide retention when dislodging forces are applied.Reciprocal Arm- Stability*a. Is placed on the lingual aspectb. It originates from the occlusal third and terminates above the highest point of contourc. Doesn’t have to engage in any undercutd. Resists lateral movement of the prosthesise. Counteracts the force produced by clasp/ retentive armf. Resists potential orthodontic movement of the abutmentBody/Minor connector = stability*Rest = support* to entire armShoulder = connects the parts of clasp assembly, function – stability
