Benefits of technology

[0014] A denture fixative composition comprising a combination of these three ingredients resists the stresses at the denture-mucosal interface encountered upon mastication. This combination also works well immediately after application and retains its fixative properties for prolonged periods of time. Additionally, denture fixatives with these three ingredients perform well under the environmental changes typically encountered in the user's mouth.

Problems solved by technology

This is sometimes difficult to achieve particularly where dentures are not fitted perfectly or where the denture fit deteriorates over time due to denture wear or changes in the mucosal denture surfaces.

Abstract

A denture fixative composition containing lower alkyl vinyl ether-maleic anhydride copolymers, water-insoluble and water-swelling polymers, and at least one additional adhesive material which can be used as a denture fixative paste, liquid, powder, aerosol, dissolving tablet, liner or adhesive-like strip.

Description

FIELD OF THE INVENTION [0001] The present invention relates to adherent compositions, and, more particularly, to denture fixative compositions. BACKGROUND OF THE INVENTION [0002] Dentures are removable appliances that serve as a replacement for missing teeth and neighboring structures in the oral cavity. Denture fixative compositions are widely used to hold dentures in place, both while the user's mouth is at rest and particularly during mastication. Such denture fixative compositions should also perform their intended function without causing irritation to the mucosal denture surfaces. Ideal denture fixative compositions make the users of dentures confident that their dentures will remain fixed in place while functioning as intended. This is sometimes difficult to achieve particularly where dentures are not fitted perfectly or where the denture fit deteriorates over time due to denture wear or changes in the mucosal denture surfaces. [0003] Denture fixatives come in many forms incl...
