Quality of Life of Edentulous Patients with Single Mandibular Implants and Mandibular Overdentures Using Two Different Attachments: A Randomized Clinical Trial.

Purpose: To compare the changes in quality of life in edentulous patients with single implants supporting mandibular overdentures with two different attachment types before implant placement and after 6 and 24 months.

Materials And Methods: Eighty edentulous patients were recruited, and all patients completed the validated Oral Health Impact Profile (OHIP)-EDENT-19 questionnaire before implant surgery. A single implant was placed in the midline of the edentulous mandibles.

Implant Stability Changes for a Single Implant Mandibular Overdenture.

Objectives:  To compare the changes in implant stability for the nonsubmerged and submerged protocols for a single-implant retained mandibular overdenture using Cendres and Metaux Locator attachment throughout a 24-month follow-up.

Materials And Methods:  Eighty edentulous patients who were seeking to install a single implant in the midline of the completely edentulous mandible. At the day of implant installation, patients were randomized into two groups using sealed envelopes: the nonsubmerged and submerged groups.
