Embodiment 1 to 6

[0242] Adhesion treatment (application of primer agent / stand for 10 seconds / dry / apply adhesive material / light irradiation for 10 seconds).

[0243] After a filling operation with a photopolymerizable composite resin (BEAUTIFIL, manufactured by SHOFU INC.), a dentin adhesion test, an adhesion durability test, and a storage stability test were conducted. The results are shown in Table 6.

[0244] It is evident from Table 6 that the adhesive system comprising the one-component primer compositions 1 to 6 has good dentin adhesiveness to enamel and dentin (after immersion in water at 37° C. for 24 hours). It was also found that the adhesive system comprising the one-liquid type primer compositions 1 to 6 has good adhesive durability because when compared with the adhesiveness of the dentin after immersion in water at 37° C. for 24 hours, with respect to the enamel Adhesion durability after about 2,000 thermal cycles of both the dentin and the adhesive strength does not decrease. ...

Embodiment 7 to 12

[0262] Adhesive treatment by a two-step type adhesive system comprising a combination of two-polymer two-liquid type adhesive material composition C or D and one-liquid type primer compositions 1 to 6 (primer application / stand for 10 seconds / dry / mix the bonding material in the same amount and apply). After a filling operation with a photopolymerizable composite resin (BEAUTIFIL, manufactured by SHOFU INC.), a dentin adhesion test, an adhesion durability test, and a storage stability test were conducted. The results are shown in Table 6.

[0263] It is evident from Table 6 that the one-component primer compositions 1 to 6 have good dentin adhesion to enamel and dentin even in the adhesive system comprising a dual polymeric adhesive material (immersion in 37 after 24 hours in water at °C). It was also found that the one-component type primer composition has good adhesion durability, because when compared with the adhesion to the dentin after immersion in water at 37° C. fo...

Embodiment 13 to 18

[0265] Adhesion treatment (primer application / standing for 10 seconds / drying / light irradiation for 10 seconds) was performed by a one-step adhesion system using one-liquid type primer compositions 1 to 6 alone, and The same tests as in Examples 1 to 6 were carried out. The results are shown in Table 6.

[0266] As is apparent from Table 6, the adhesive systems using the one-component primer compositions 1 to 6 alone showed: in any one of dentin adhesiveness, adhesive durability, and storage stability, enamel and dentin. Both were stable in adhesiveness, although at a low level compared with an adhesive system using a combination of a photopolymerizable one-component type and a double-polymerized two-component type adhesive material.

Abstract

The invention relates to an adhesive coating composition for dentistry applied to dentistry field, used to bond dental materials, such as restoration materials, tooth crown materials, prosthesis materials, beautifying materials, rectifying materials, preventing materials, supporter constructing materials or pulp canal materials and so on, onto ceramics, metals, resin, compound resin, glass ionomer cement, hard biological tissues (enamel or dentine of natural teeth) and so on. The invention provides an adhesive coating composition for dentistry including an adhesive composition for dentistry which cannot only be used with another adhesive composition together, but also can be used independently.

Description

technical field [0001] The present invention relates to a dental adhesive primer composition for use in the field of dentistry for bonding dental materials such as restorative materials, crown materials, prosthetic materials, aesthetic materials, orthodontic materials materials, prophylactic materials, core build-up materials, and root canal materials bonded to ceramics, metals, resins, composite resins, glassionomer cements, and hard biological tissue (of natural teeth) enamel or dentin). The present invention also relates to a dental adhesive primer composition comprising a dental adhesive composition which can be used not only in combination with another adhesive composition but also Use alone. Background technique [0002] Since composite resins have significantly improved long-term durability and mechanical properties, and also have properties such as fluorine sustained release and X-ray contrast, when defects in the tooth substance are caused by the onset of caries o...
