To enable the easy peeling of a silicone rubber member adhered by using an adhesive to a base material of a resin dental plate or the like backed by a silicone backing material from this base material by penetrating a solvent which enables solving on swelling a synthetic resin into a joint part at the time of removing this silicone rubber member.

When the silicone member is peeled from the resin base material of the dental article formed by adhering the silicone member to the front surface of the resin base material consisting essentially of the synthetic resin by using the adhesive, a specific solvent is penetrated into the joint part between the resin base material and the silicone member. While a method of penetrating this solvent into the joint part is not particularly restricted, a method of dropping or applying the solvent near to the peripheral edge of the joint part by using a syringe or brush, etc., is exemplified. At least one kind of the solvent selected from acetone, methylene chloride, ethyl acetate, chloroform, etc., are preferably used as the specific solvent if the synthetic resin which is the essential component of the resin base material is an acrylic resin.
