Embodiment 1

[0041] by As biphenyl di(meth)acrylate monomer (100 parts by weight), bis(2,4,6-trimethylphthalide)phenylphosphine oxide (BAPO) was used as bisacylphosphine oxide (0.5 parts by weight parts), with camphorquinone (CQ) as α-diketone (0.5 parts by weight), and 4-N, N-dimethylaminobenzoic acid ethyl (PDE) as tertiary amine (0.5 parts by weight), prepare the present invention dental composition.

[0042] The liquid-type adhesive material prepared by using the composition has a bonding strength of 18.1 MPa with dentin; after the liquid-type adhesive material is placed in a thermostat at 50° C. for 4 weeks, the material hardly changes color by visual inspection.

Embodiment 2

[0044] by As biphenyl di(meth)acrylate monomer (100 parts by weight), bis(2,4,6-trimethylphthalide)phenylphosphine oxide (BAPO) was used as bisacylphosphine oxide (6 parts by weight parts), with camphorquinone (CQ) as α-diketone (4 parts by weight), and 4-N,N-dimethylaminobenzoic acid ethyl (PDE) as tertiary amine (1 part by weight), prepare the present invention dental composition.

[0045] The liquid-type adhesive material prepared by using the composition has a bonding strength of 20.1 MPa with dentin; after the liquid-type adhesive material is placed in a thermostat at 50° C. for 4 weeks, the material hardly changes color by visual inspection.

Embodiment 3

[0047] by As biphenyl di(meth)acrylate monomer (100 parts by weight), bis(2,4,6-trimethylphthalide)phenylphosphine oxide (BAPO) was used as bisacylphosphine oxide (4 parts by weight parts), with camphorquinone (CQ) as α-diketone (6 parts by weight), and 4-N, N-dimethylaminobenzoic acid ethyl (PDE) as tertiary amine (5 parts by weight), prepare the present invention dental composition.

[0048] The liquid-type adhesive material prepared by using the composition has a bonding strength of 19.4 MPa with dentin; after the liquid-type adhesive material is placed in a thermostat at 50° C. for 4 weeks, the material hardly changes color by visual inspection.

Abstract

The invention discloses a dental composition suitable for an LED light source. The dental composition is characterized by comprising (1) a photopolymerization initiator composition, and (2) biphenyl di(methyl) acrylate monomer with more than two aromatic rings connected by a C-C bond. The photopolymerization initiator composition (1) contains a photopolymerization initiator component only comprising bisacylphosphine oxide (A) and alpha-diketone (B), and tertiary amine (C). Under light curing by an LED illuminator, the dental composition performs high curability and excellent adhesion to dentin; the dental composition is not easy to change color even after long-term storage, and has small adhesion reduction and excellent storage stability.

Description

technical field [0001] The invention relates to the field of dental technology, in particular to a dental polymerizable composition suitable for photopolymerization by using a light emitting diode (LED) light source. Background technique [0002] In dental treatment, in order to restore the caries and defect of the tooth, the caries and defect are filled with a photocurable dental material containing a photopolymerization initiator, and the dental material is cured by irradiating light with a dental irradiator. to repair. [0003] For example, as a material used in tooth restoration, Patent Document 1 discloses a photocurable dental material, which is characterized in that it contains a (meth)acrylic acid ester polymerizable monomer, a phthaloyl oxide-based polymerization initiator, and an amine compound. [0004] Patent Document 2 discloses a polymerizable composition containing two or more different polymerization initiators. Specifically, a polymerizable composition con...
