SINGLE DENTURES...
The pressures applied to the upper denture by natural teeth are many times greater than those supplied by the lower dentures. As a result, the single upper denture can easily be moved and tissue changes occur at a much faster rate.
Any slight deviation from an ideal mouth magnifies itself when an upper denture is subjected to the tremendous forces of natural teeth. The majority of people who wear single upper dentures are not happy about the retention, but when they lose the lower teeth and wear upper and lower dentures, they no longer complain about this same retention.
The reason is the failure to create the forces formally exerted by the lower natural teeth. Every time a patient with a single upper denture has a meal, it is easy to subject their denture to pressures that are damaging. Patients with single upper dentures are often tempted to eat everything, and being free of a troublesome lower denture, most of them see no need to change their eating habits.
Actually, the same limitations that are placed on upper and lower dentures apply to single uppers. Failure to heed this warning will only result in trouble.
