U.S., Feb. 28 -- ClinicalTrials.gov registry received information related to the study (NCT07439237) titled 'Implant-supported Maxillary Overdentures; a 15-years Evaluation' on Feb. 23.

Bar-retained implant overdentures can be supported by 4 or 6 implants, splinted by a bar. Evidence on maxillary implant overdentures has been mostly short to medium term, non-comparing or retrospective. Even more, 15-years data of comparative studies are lacking.
