Precision attachments are retainers for removable bridgework partial dentures and full dentures (overdenture) where few abutments remain. The main purpose besides retention is its concealment within or under a restoration as a better alternative to a visible clasp retainer. As precision attachment consists of two functional units. The primary part is incorporated into the abutment construction and the secondary part is built into the removable appliance, bridge, partial denture or full denture. A dentist who wishes to use precision attachments should have a basic understanding of fine mechanics.
