发明名称 Dental impression tray with improved adhesion to impression material
摘要 A dental impression tray has a receptacle for receiving a quantity of dental impression material, and the receptacle is coated with an adhesive for enhancing the bond between the impression material and the tray. The adhesive is applied to the tray body at least sixteen hours before the impression material is placed in the receptacle. Advance coating of the adhesive onto the tray body provides a higher bond strength between the impression material and the tray than would otherwise be observed. Precoating of the tray by the manufacturer represents a time savings for the dental practitioner and also reduces the amount of volatilized solvent emitted from the adhesive that might otherwise be emitted in the dental office.
