When placing a prosthesis in a patient with challenging anatomy, a clinician can benefit from using an attachment system like a Hader Bar, the most popular and versatile bar attachment in the world. Its low profile provides secure retention options and is simple to service.
The Hader Bar overdenture can be effective for cases where:
• The bone quantity and quality requires splint-like support to protect the implants.
• The prosthesis needs to be stabilized because the denture flange cannot engage the atrophied ridge.
• Divergent implants need to be accommodated.
The Hader Bar’s design provides advantages over other overdenture systems. Its strength and flexibility allows for vertical and rotational movement, making it ideal for:
• A two-abutment bar with a single straight section
• Protecting abutments
• Multiple bar sections
• Rigid or fully abutment-supported prostheses
The bar itself comes in plastic or Plasti-Wax, and there are two types of metal housing to encase the plastic retentive clips in the denture, the Traditional Hader Housing and the Alignment Hader Housing. The Alignment Housings are ideal for the anterior—0.8mm thinner than the Traditional Housings, and only 0.3mm taller. If vertical space is not an issue, they may also be used in the posterior as well as they provide more mechanical retention in acrylic and help parallel the clips. The Traditional Housings are wider yet shorter, but don’t have the mechanical retention of the Alignment Housings. If space is at a premium, consider these in the posterior.
However, the most important piece of the system is the green processing spacers. They maintain attachment parallelism and create a tunnel wide enough for the clips to function and flex during insertion and removal. The Hader clips come in four retention levels so you can provide the appropriate retention level to fit your patient needs.
The Hader Bar can also save space in your patient’s mouth compared to other bar attachments. The bar is 2.5mm high; the attachments are 1.5mm high; the total width is 4.2mm.
The Hader Bar is also easy for a clinician to examine and maintain. Replacing a clip takes less than 30 seconds.

“Hader Bars are very easy to work with if you’re using the correct protocol and procedures,” Bormes explains, reviewing how to get the most effective results with the system.
