Semiprecision attachment: a connecting link between the removable and fixed prosthesis

Abstract

Oral rehabilitation of partially edentulous arches requires careful treatment planning before any prosthodontic intervention. The connection of the metal framework of fixed (fixed dental prosthesis (FPD)) and removable partial denture using adhesive attachments is a good alternative prosthetic option when solely fixed prosthesis (FPD or implant) cannot be used due to anatomical limitation. Attachments are the tiny interlocking devices that act as a hybrid link to join removable prosthesis to the abutment and direct the masticatory forces along the long axis of the abutment. This joint acts as a non-rigid stress breaker, which helps in distributing the occlusal load. Precision and semiprecision attachment have always been bordered by an aura of mystery due to technique sensitive procedure and lack of knowledge. The following case describes a combined contemporary and conventional approach and treatment sequence with the use of attachments for the rehabilitation of partially edentulous arches.
