Satisfactory restoration in a patient with a partially edentulous situation can be challenging especially when unilateral or bilateral posterior segment of teeth is missing. Successful restoration can be done with various conventional and contemporary treatment options. One such treatment modality is attachment-retained cast partial dentures. This paper describes a case report of a patient with mandibular bilateral distal extension edentulous span restored with a cast partial denture having an extracoronal castable precision attachment (RHEIN 83 OT CAP attachments system). Keywords: Precision attachment, Removable denture, Retentive denture.
