Outcomes

Primary Outcomes

Change of Retention

Retention was measured for both groups using the universal testing machine. Modification in each denture was made where two small metal tubes (3 mm diameters) were placed a few millimeters above the laterals in maxillary dentures by self-cure acrylic resin. The distance between the right tube and the geometric center was almost the same distance as between the left tube and the geometric center. The exact distance was checked using an orthodontic wire.
