U.S., July 31 -- ClinicalTrials.gov registry received information related to the study (NCT07093853) titled 'Mandibular Overdentures Retained by Four Locator Attachments Versus Four-Implant Bar Attachments' on July 22.

Brief Summary: This 10-year retrospective study investigates residual ridge changes in edentulous patients treated with mandibular overdentures (ODs) retained by either four Locator attachments or a four-implant bar system. Although two-implant ODs are well established, four-implant configurations may offer enhanced stability and function. Locator and bar attachments are commonly used, but their long-term effects on bone resorption patterns-especially posterior mandibular and anterior maxillary resorption-remain unclear. By ...
