Building on the proceedings of the McGill conference: implant-retained overdentures in an area of South America.
OBJECTIVE
Since the McGill consensus conference, numerous reports have proposed the advantages of the 2-implant-retained overdenture over the conventional denture in the restorative management of the edentulous mandible. The purpose of this article was to demonstrate the use of the 2-implant-retained overdenture in the restorative management of patients with edentulous mandibles in an impoverished population.


METHODS
To address the study's purpose, the investigators initiated a retrospective cohort study and enrolled a sample of subjects who had mandibular 2-implant overdenture treatment using the protocol described within. The primary predictor variable was whether the patient had mandibular 2-implant overdenture treatment. The primary outcome variable was survival of mandibular 2-implantoverdenture treatment as defined within.


RESULTS
The study sample included 35 patients each of whom had 2 mandibular implants placed for a total of 70 implants inserted with the purpose of retaining a mandibular overdenture. The mean clinical follow-up time was 74.7 months, during which there were no incidences of implant failure. Therefore, analytical and survival analyses could not be performed.


CONCLUSIONS
Given the increase in quality of life and ease in implementation, clinicians should now be suggesting the mandibular 2-implant overdenture as the treatment of choice in the management of the edentulous mandible.
