title: A new clapsing system for unilateral distal-extension removable partial dentures.
abstract: The background, rationale, and technique for fabricating the remodified Hart-Dunn attachment system have been presented. This subpontic attachment is a product of clinical experience in managing the unilateral distal extension removable partial denture patient. Minimal retention, reduced torque throughout the arch during function, and distribution of force according to sound mechanical principles make this remodified subpontic attachment the preferred method of treating most unilateral distal extension removable partial denture patients.
