Conventional Dentures
Tooth loss increases with age
the number of edentulous people will continue to increase for
several decades because of the increase in mean age.
Complete dentures have been the traditional standard of
care for edentulous patients for more than a century.
Complete denture wearers are usually able to wear an
upper denture without problems, but many struggle with
the complete lower denture because they are loose.
Conventional dentures have a bite force of 25% and 20%
chewing efficiency of natural teeth.
