I recently commented (in a wonderful post by @denturequeen) that Hader Bars can be an extremely useful option in certain situations. Here is one of them.
Why did I make a removable prosthesis here utilizing a Hader Bar? Especially with 5 implants and a very favorable A-P spread? Below are my reasons, what would you have done?
1. Why removable rather than fixed? I choose removable when a flange is needed for proper lip support (the situation here), and when patients prefer/ request it. Yes, these patients do exist! And it’s usually for reasons like it’s what they are used to or they want better access for hygiene.
2. Why not individual stud-type attachments such as Locator abutments? Some studies suggest lowest implant survival rates with unsplinted dental implants utilized with overdentures in maxillary bone (this has also been my experience). Studies also show highest implant survival rates with splinted implants. And the situation here was a maxilla with very low bone density.
3. Why a Hader Bar? While I typically use Locators attachments for my overdentures, Locators placed on a milled bar (see second pic) consume more vertical height than a Hader Bar. For Locator, there is the minimum bar height plus the Locator height and then the housing as well, while the Hader Bar itself already has the retentive element in its design and no additional housing needed. It’s much shorter! And Hader clips are very retentive and hold up very well over time.
