WHY HADER BARS ARE THE BEST OPTION

FOR BAR OVERDENTURES

Indications:

• In the maxillae, the bone quality and quantity often dictates the use of a bar to protect the
implants in weaker bone via splinting.

• In the resorbed mandible, the atrophied ridge can not be engaged by the denture flange and

therefore does not provide prosthesis stability.
• Extremely divergent implants are easier to accommodate with a bar overdenture.

Advantages of the Hader Bar:

• Flexibility in Prostheses Function:
o Metal Ackermann clips provide both vertical
and rotational movement, ideal for 2 abutments bar
with a single straight section and for protecting abutments.
o Plastic Hader clips provide rotational movement.
Ideal for restorations utilizing multiple bar sections
and/or for rigid/fully abutment supported prostheses.

• Space Saving:
o Total vertical height of bar, 2.5mm.
Total vertical of attachments, 1.5mm.
Total width of attachment, 4.2mm.
• Easy to Service:
