| 제목 | Dental adhesive and use thereof in preparing dental impression |
| 초록 | An organopolysiloxane adhesive contains an organopolysiloxane pressure sensitive adhesive, organopolysiloxane rubber base, an aliphatic unsaturated-functional MQ resin and a polyhydrido-functional organopolysiloxane in an organic solvent, and exhibits differential adhesion between dental impression material and dental impression tray material. In restorative dentistry, for example the preparation of crowns, bridges, and dentures, a casting operation is used which requires reasonable degree of accuracy in recreating the natural contours of teeth and gums. For such purposes, a female casting, or "impression" is made in the mouth, using a curable dental "impression" material. In preparing such impressions, an impression tray is used. This impression tray is a U-shaped trough which fits over the teeth and gums, and which may be made of plastic, metal or other materials. A curable polymer impression material is placed in the tray, and the tray pushed down(or up) onto the teeth and gums. Following cure, the tray and cured impression material is removed. However, in order to remove the cast impression from the oral cavity, it is necessary for the impression matefial to exhibit greater adhesion to the dental tray than to the teeth and gums. In general, impression materials have insufficient adhesion for this purpose, and thus a dental adhesive is used between the tray and impression material. However, the nature of the impression tray surface on the one hand, and the impression material on the other hand, makes formulation of an adhesive which can suitably adhere to both tray and impression material difficult.
