The invention discloses a method for bonding and combining a zirconia restoration body and a natural tooth, which does not adopt the prior sand blasting process for treatment, but carries out milling processing on the surface of dental zirconia-based ceramic, carries out surface roughening by preparing micro-textures on the surface under the conditions of not causing mechanical trauma of materials and not influencing the later mechanical strength of the dental zirconia-based ceramic, improves the specific surface of the zirconia ceramic, and further strengthens the bonding and combination between the zirconia restoration body and the natural tooth by using resin as an adhesive through the methods of surface treatment, film coating, novel sand blasting and the like. |
