HYDROPHOBIC DENTAL BLEACHING SYSTEMS AND METHODS OF APPLICATION Russian patent published in 2009 - IPC A61K8/23 A61K8/89 A61Q11/02 

FIELD: individual supplies.

SUBSTANCE: present invention refers to dental bleaching systems containing the compositions including hydrophobic polymers. There is disclosed dental tray for dental bleaching treatment, comprising a dental tray essentially enclosing anterior and posterior surface of tooth. Said dental tray has essentially water-insoluble bleaching composition of viscosity approximately 50000 centipoises to approximately 900000 centipoises and containing a bleaching agent and hydrophobic polymer, representing a condensation product of silicone resin and organosiloxane. Said polymer consists of approximately 50-70 parts of silicone resin and 30-50 parts of organosiloxane polymer.

EFFECT: disclosed invention provides intensified bleaching effectiveness, higher available concentration of the bleaching agent, adhesion of the bleaching composition to surface of a tooth even without saliva, and prolonged and controlled release of the bleaching agent for a long period of time.
