Milled in versus round bar for mini implant retained mandibular overdentures: a 8-year retrospective radiographic study of peri-implant bone changes and posterior ridge resorption.

Objective: This retrospective radiography study's main objective was to compare round and milled bars for mandibular overdentures assisted by 4 mini-dental implants (MDI) on peri-implant marginal bone loss (MBL)and posterior mandibular ridge resorption(PRR) after 8 years.

Materials And Methods: Thirty male Participants in a retrospective analysis were treated between 2016 and 2024 who had four interforaminal mini implants supporting an overdenture on a milled bar. Two equal groups of 15 patients each were randomly assigned to receive mandibular overdentures: Group I received overdentures retained by milled bars, while Group II received overdentures retained by round joint bars.

A Clinical and Radiographic 3 Years Retrospective Study for Two Types of Locator Retained Mandibular Implant Overdenture.

Introduction: This retrospective study aimed to evaluate peri-implant marginal bone loss (MBL) and prosthetic complications between two types of locator attachments in two implant-supported mandibular overdentures.

Material And Method: From the archived records, information about patients who had two implants inserted utilizing two different types of locator attachments into the interforaminal region between November 2019 and December 2023 was obtained. Overall, 60 patients (Total = 120 implants) from the archive records of the Prosthodontics Department, Faculty of Dentistry, Mansoura University, with ages ranging from 40 to 60 (mean age 50), were included in the study.
