Abstract
fourteen readymade mandibular edentulous epoxy resin models were used. Two implant analogues were installed in the canine area. Two non-hex titanium base (Ti-base) abutment were connected to the implant analogues. The epoxy cast with Ti-base abutment was scanned by a laboratory scanner. Designing of the bar on the software was done and converted to STL file. The STL file was transferred to the milling machine for manufacturing of the bar. The milled PEEK bar (BioHPP) was cemented to the abutment by resin cement adhesive material. group A was ready made plastic clip and group B was milled PEEK (BioHPP) clip. Dentures were constructed by the conventional method and direct pickup of the clips were done. The final constructed mandibular overdentures were subjected to 150,000 cycle of bi-axial chewing simulating cycles which equal 1 year follow up and 1440 insertion removal cycles which equal 4 times insertion and removal per day.
