Denture, method of repairing denture and dental soft relining material used therefor

A method of repairing a denture comprising applying a dental soft relining material containing:

• (E) 100 parts by weight of an organopolysiloxane;
• (F) 0.05 to 15 parts by weight of an organic peroxide;
• and
• (D) 5 to 300 parts by weight of a fine particle of a polyorganosilsesquioxane;
• onto the mucosa surface of the denture and/or onto an alveolar model, and then adhering said denture to the alveolar model with force followed by heat-curing.

A denture comprising a denture and a layer of a soft relining material provided on the side of the mucosa surface of said denture, wherein said soft relining material comprises a cured product of a composition which contains:

• (A) 100 parts by weight of an organopolysiloxane having in a molecule thereof at least two organic groups with a terminal unsaturated bond;
• (B) an organohydrogenpolysiloxane having in a molecule thereof at least three hydrogen atoms bonded to silicon atoms, in such an amount that the number of said hydrogen atoms is 0.5 or greater per one unsaturated bond in the component (A);
• (C) a platinum catalyst in an amount of 0.1 to 1000 ppm reckoned as platinum atoms with respect to the total amount of the component (A) and the component (B);
• and
• (D) 5 to 900 parts by weight of a fine particle of a polyorganosilsesquioxane.

• and
• (D) 5 to 300 parts by weight of a fine particle of a polyorganosilsesquioxane.

A method of repairing a denture with a dental soft relining material which comprises removing a portion of the denture to thereby expose a new surface to be relined with the dental soft relining material, applying to the exposed surface a dental soft relining material comprising:

• (A) 100 parts by weight of an organopolysiloxane having in a molecule thereof at least two organic groups with a terminal unsaturated bond;
• (B) an organohydrogenpolysiloxane having in a molecule thereof at least three hydrogen atoms bonded to silicon atoms, in such an amount that the number of said hydrogen atoms is 0.5 or greater per one unsaturated bond in the component (A);
• (C) a platinum catalyst in an amount of 0.1 to 1000 ppm, measured as platinum atoms, with respect to the total amount of the component (A) and the component (B);
• and
• (D) 5 to 300 parts by weight of a fine particles of a polyorganosilsesquioxane,
• fitting the denture with relining material into the oral cavity of a patient, allowing the applied dental soft relining material to cure, and removing the denture with cured relining material from the oral cavity.
