Purpose: To assess and compare the retentive force of two female matrix retention system
(RS with a conventional O-ring [OR] attachment system) in tooth-supported overdenture.
Materials and Methods: Completely edentulous mandibular model with two canine root-
anchored ball attachments for overdentures were fabricated. A total of 30 mandibular
