Management of Long Span Kennedy’s Class IV Situation with a Fixed Removable Entity

Abstract

The treatment modality for treating a patient within the Kennedys class IV with long edentulous span situation demands biomechanical level of balance followed by good aesthetics. The long edentulous span complicates the matter due to the unavailability of sufficient number of abutments to support the synthetic oral prosthesis. Conventional removable prosthesis is not advised for an equivalent reason. This case report describes a way for the fabrication of a custom attachment to retain prosthesis. A cast partial removable denture is retained by a custom attachment. The patrix a part of the custom attachment is fabricated using castable semi precision attachment Rhien 83. The matrix a part of the attachment is fabricated using castable precision attachment 83 which is constituted by embedding inside the tissue-fitting surface of the prosthesis. This manuscript describes custom attachment for rehabilitating the long-span Kennedy class IV situation.
