Retentive bar overdenture fabrication with preformed castable components: a case report.

Overdenture bar attachment therapy is a rarely chosen treatment option in today's aggressive environment of implant treatment. However, overdenture therapy preserves the sensation of proprioception, preserves the edentulous ridge, maintains the border seal, and provides the patient with good speaking ability and chewing efficiency. The use of preformed components for impression posts, plastic burnout post patterns, plastic burnout bar patterns, attachable screw attachments, and nylon retention clips, which are quickly replaced clinically and induce minimal wear on the bar, have made the fabrication of the overdenture bar attachment easier, quicker, and more precise. This article details the fabrication of a canine splint bar for a bar and clip-retained mandibular overdenture that opposes a complete maxillary denture.
