Palateless Maxillary Implant-Supported Overdentures: A Review of Patient Satisfaction and Clinical Outcomes Along...

Implant-supported overdenture is a lifesaver treatment plan for edentulous patients. Implant numbers and positions in the maxilla and mandible are controversial, but in more studies on a minimum number of implants, which is at least four implants in the maxilla and two implants in the mandible, there is a consensus. Also, the attachment system (splinted vs. unsplinted) does not have a significant effect on bone loss, implant and prosthesis survival rate, and clinical complications. Palateless maxillary overdentures supported on four implants may improve taste sensation and reduce gag reflex without negatively affecting retention, resistance, and chewing ability. The aim of this study was to present three maxillary implant-supported overdenture cases with four implants without palatal coverage.
