MANDIBULAR IMPLANT-SUPPORTED PRECISION ATTACHMENT-RETAINED FIXED PROSTHESIS: CASE REPORT

Background: A common clinical problem confronting prosthodontists is the design and maintenance of edentulous mandibular by the fixed implant-supported prosthesis. Purpose: Aim of the paper is to study and describes the rehabilitation of a patient with edentulous mandible via precision attachment-retained implant-supported fixed prosthesis to compensate for the effect of mandibular deformation. Materials and Methods: In one patient scheduled for the implant-supported prosthetic substructure was divided into three parts, the interforaminal region, and the posterior segments were not connected rigidly, but by a precision, attachment reducing the tension that can occur around the implant by increasing the precision and passive fit. Results: Two years after the delivery of the prosthesis to the patient, the fit of the substructure and, the bone adaptation around the implant were observed not to have deteriorated in the radiograph. Conclusions: Precision attachment-retained mandibular implant-supported fixed prosthesis used in an edentulous patient is a good alternative to reduce mandibular deformation and provide good stabilization and retention.
