Introduction: The implant-retained overdenture is an alternative treatment option for edentulous patients that provides
better retention, stability, function, esthetics, and better quality of life. Because of continuous alveolar bone resorption,
implant-retained overdentures need to be relined. The purpose of this presentation is to step by step describe a
method of relining an implant-retained overdenture.
Method: A 65-year-old ASA I patient sought care for trauma and pain in the oral mucosa underneath his mandibular
implant-retained overdenture. In addition, the patient mentioned the denture’s lack of stability during function. On the
basis of the patient’s dental history, clinical and radiographic examination, there was alveolar bone resorption.
Relining a mandibular implant-retained overdenture with a Locator attachment system on 2 implants is achieved
through clinical and laboratory steps.
Results: The first part of the clinical steps involve the removal of the undercuts, creation of tissue stops, check of the
occlusion in centric relation, removal of the Locator housing from the denture, placement of the locator impression
copings and impression with polyether medium-bodied consistency material.
The laboratory steps consist of snapping the Locator analogs into the Locator impression copings, pouring of the
master cast, investment of the cast with the denture in a flask, boil it out and discard of the green compound material,
placement of the block-out spacer rings over the analogs and pressure of the Locator housing onto the analogs using
the black resilient caps, processing after packing with heat-polymerizing acrylic resin, deflask, finish and polish of the
The second part of the clinical steps involve the replacement of the black resilient processing liner caps with the
extralight angled, retention-resilient red liner caps, placement of the denture intraorally, check of the stability and the
occlusion, and final delivery to the patient.
Conclusion: The technique that was described in this case report, analyzed the procedure of the relining of an
implant-retained overdenture using a Locator attachment system. The goal of this technique is to eliminate patients’
tissue trauma and pain and increase the stability and support of the prosthesis.
