Steel-backed soft-lined dentures

technical field

The invention relates to the technical field of dentures, in particular to a steel-backed soft-lined denture.

Background technique

Dentures are dentures that are inlaid to restore functions such as chewing, aesthetics, and pronunciation after tooth loss or extraction. The bases of existing dentures are mostly made of resin materials. The contact between the hard base and the oral cavity will make the wearer feel uncomfortable, and the strength of the resin is not high. The bite force during chewing will cause the base base to deform or crack, thus affecting wearing In addition, a small number of bases are made of stainless steel plate, which enhances the strength of the base, but increases the discomfort of the wearer. The direct contact between the metal base and the oral cavity sometimes causes damage to the inner wall of the oral cavity and gums. Damage greatly affects the wearing practicality and wearing effect.
