The following is a case presentation for a bar overdenture.

Learn about our Unibase System that will save you time and money!


Implant exposed after removal of the healing abutment.
The Dual-Purpose impression/bar copings are screwed into place, ready for an ,open tray impression technique.
An open tray impression technique is used to ensure greater accuracy of the master cast
Master cast is poured and the dual-purpose impression/bar copings are now ready for modification
After model is poured, retention heads are removed
Once the retention heads are removed the remainder of the dual-purpose component serves as a solid titanium bar coping

Titanium DolderTM Bar

A variety of pre-fabricated titanium bar stock is available

Once the bar copings are modified, pre-fabricated titanium bar stock is measured and cut to fit between the copings
Non-critical laser welds
Critical welds are carefully completed

Bar assembly prior to attachment configuration

Bar assembly can now be returned to the doctor for fit verification

A light cured base is made with screw access holes. A bite block is added. Doctor can now verify model accuracy and register centric relationship.
Attachment configuration is determined by treatment plan and is laser welded to place
A variety of retention options are available and reversible without risk of remake.

 
Laser assembled implant bars go through metamorphosis, starting as a verification bar...

…and evolving into a completely laser assembled implant support frame.

 


UNIBASE- the final overdenture base at try-in

Saves master cast for future bar maintenance
Determine retention at try-in
Can fabricate 2nd denture now!

The UNIBASE is the final overdenture base processed with attachments. . We block-out the bar and undesirable undercuts in wax and process the UNIBASE in pour acrylic. The dentist can test the retention of the prosthesis at the wax try-in. After try-in, we simply process the teeth to the UNIBASE with conventional acrylic processing. The bar is spared from harsh acrylic packing procedures and the master cast is saved for future bar maintenance or reconstruction. This technique also allows us to fabricate a second overdenture without additional impressions or jaw relationship. This spare prosthesis can be fabricated at a greatly reduced cost.
