Denture with Overbar

Implant bar overdentures combine the stability of an implant with the look of a denture, seating directly onto the gum line implant using as few as four screws. This hybrid implant option gives a patient a lifelike strength and firmness.

Indications

Edentulous patients requiring enhanced retention and stability through implant support
Cases with sufficient bone volume for bar-supported implants
Patients seeking improved chewing efficiency and speech over traditional dentures
Individuals with difficulty retaining conventional dentures due to ridge resorption
Situations where a removable solution is preferred over a fixed restoration

Contraindications

Insufficient bone volume or quality for implant placement
Poor oral hygiene or lack of compliance with maintenance protocols
Uncontrolled systemic health conditions (e.g., diabetes, immune suppression)
Bruxism or parafunctional habits that may damage the bar or attachments
High esthetic demands in areas where bar components may be visible

Preparation

Comprehensive evaluation and planning using CBCT and digital models
Surgical placement of 2–6 implants, depending on arch and design
Healing period of 3–6 months before bar and prosthesis fabrication
Precise impression taking using open or closed tray techniques for implant position
Try-in of framework and wax setup to assess esthetics and function before processing

Cementation

The overdenture is removable and typically retained with clip attachments on the bar. The bar itself is screw-retained onto implants.

Tech Notes

The bar is milled or cast from titanium or a cobalt-chrome alloy
Attachments (e.g., Hader, Dolder, or Locator bars) provide retention and can be replaced as needed
Overdenture is processed with a reinforced acrylic base and high-impact denture teeth
Regular maintenance of clips and periodic reline may be required over time
Patient education on hygiene around implants and under the bar is critical
