Description

Technical Field

[0001] This invention relates to the field of adhesive technology, and more specifically, to a dental adhesive. Background Technology

[0002] Dental adhesives have a long history of use in dentistry. Tooth restoration typically involves applying dental adhesives and subsequent restorative materials to the tooth structure. Dental adhesives are also used for tooth restoration, reattachment of broken teeth, veneers for stained or malformed teeth, stabilization of loose teeth, fixation of alveolar and frontal bone injuries, bonded bridges, and orthodontic treatment.

[0003] With advancements in medical technology, clinical requirements for surgical procedures and auxiliary materials are becoming increasingly stringent, driving the research and development of dental adhesives. However, existing dental adhesives still suffer from low adhesion to teeth and poor antibacterial properties, significantly limiting their application. Summary of the Invention

[0004] This invention proposes a dental adhesive that solves the problems of low adhesion and poor antibacterial properties in related dental adhesives.

[0005] The technical solution of the present invention is as follows:

[0006] A dental adhesive comprises the following components in parts by weight: 25-40 parts of an acrylate compound, 5-8 parts of an initiator, and 45-50 parts of a diluent, wherein the initiator comprises camphorquinone and a hydrated terpene diol elixir.

[0007] As a further technical solution, the acrylate compound includes any two combinations of dimethacrylate, 2-hydroxyethyl methacrylate, and bisphenol A glycidyl methacrylate.

[0008] As a further technical solution, the acrylate compound includes glyceryl dimethacrylate and 2-hydroxyethyl methacrylate.

[0009] As a further technical solution, the mass ratio of the dimethacrylate to the 2-hydroxyethyl methacrylate is 20~30:5~10.

[0010] As a further technical solution, the mass ratio of the glyceryl dimethacrylate to 2-hydroxyethyl methacrylate is 26:8.

[0011] As a further technical solution, the mass ratio of camphorquinone to hydrated terpene diol elixir is 1~2:4~6.

[0012] As a further technical solution, the mass ratio of camphor quinone to hydrated terpene diol elixir is 2:5.

[0013] As a further technical solution, the diluent is acetone.

[0014] The present invention also proposes a method for preparing a dental adhesive, comprising the following steps: mixing the components uniformly to obtain a dental adhesive.

[0015] As a further technical solution, the mixing is carried out by stirring at a speed of 10-25 rpm for a time of 30-60 min.

[0016] As a further technical solution, the order of addition of each component is: acrylate compound, initiator, diluent.

[0017] The working principle and beneficial effects of this invention are as follows:

[0018] 1. This invention uses hydrated terpene diol elixir and camphor quinone as initiators to provide a dental adhesive. The hydrated terpene diol elixir can not only increase the antibacterial properties of the product, but also improve the shear strength of the adhesive, thus solving the problems of low adhesion and poor antibacterial properties of dental adhesives in related technologies, and achieving the effect of improving the adhesion and antibacterial properties of dental adhesives.

[0019] 2. This invention uses hydrated terpene diol elixir and camphor quinone in a mass ratio of 2:5 as initiators, which further improves the shear strength and antibacterial properties of dental adhesives. Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] Add 26 parts of glyceryl dimethacrylate, 8 parts of 2-hydroxyethyl methacrylate, 2 parts of camphorquinone, 5 parts of hydrated terpene diol elixir, and 48 parts of acetone to a mixer in sequence. Mix at 20 rpm for 45 minutes until the color is uniform. Fill into containers to obtain the dental adhesive.

[0023] Example 2

[0024] Add 26 parts of glyceryl dimethacrylate, 8 parts of 2-hydroxyethyl methacrylate, 2 parts of camphorquinone, 4 parts of hydrated terpene diol elixir, and 48 parts of acetone to a mixer in sequence. Mix at 20 rpm for 45 minutes until the color is uniform. Fill into containers to obtain the dental adhesive.

[0025] Example 3

[0026] Add 26 parts of glyceryl dimethacrylate, 8 parts of 2-hydroxyethyl methacrylate, 2 parts of camphorquinone, 6 parts of hydrated terpene diol elixir, and 48 parts of acetone to a mixer in sequence. Mix at 20 rpm for 45 minutes until the color is uniform. Fill into containers to obtain the dental adhesive.

[0027] Example 4

[0028] Add 26 parts of bisphenol A glycidyl methacrylate, 8 parts of 2-hydroxyethyl methacrylate, 2 parts of camphorquinone, 5 parts of hydrated terpene diol elixir, and 48 parts of acetone to a mixer in sequence. Mix at 20 rpm for 45 minutes until the color is uniform, then fill into containers to obtain a dental adhesive.

[0029] Example 5

[0030] Add 20 parts of glyceryl dimethacrylate, 5 parts of 2-hydroxyethyl methacrylate, 1 part of camphorquinone, 4 parts of hydrated terpene diol elixir, and 45 parts of acetone to a mixer in sequence.

[0033] Comparative Example 1

[0034] The only difference from Example 1 is that no hydrated terpene diol elixir is added.

[0035] The dental adhesives obtained in Examples 1-6 and Comparative Example 1 were tested for shear strength according to the method in YY / T0518-2009 and for antibacterial properties according to the method in GB / T 23763-2009. The test results are recorded in Table 1.

[0036] Table 1 Shear strength and antibacterial properties of dental adhesives

[0037]

[0038] As can be seen from Table 1, the dental adhesive provided by the present invention has good shear strength and antibacterial properties.

[0039] Compared to Examples 2 and 3, the dental adhesive obtained in Example 1 had a better shear strength than that obtained in Examples 2 and 3, with a mass ratio of camphorquinone to hydrated terpene glycol elution of 2:5 in Example 1, 2:4 in Example 2, and 2:6 in Example 3. This indicates that the dental adhesive exhibits optimal adhesion and antibacterial properties when the mass ratio of camphorquinone to hydrated terpene glycol elution is 2:5.

[0040] Compared with Example 4, Example 1 added glyceryl dimethacrylate and 2-hydroxyethyl methacrylate, while Example 4 added bisphenol A glycidyl methacrylate and 2-hydroxyethyl methacrylate. The dental adhesive obtained in Example 1 had higher shear strength and antibacterial properties than that obtained in Example 4, indicating that the combination of glyceryl dimethacrylate and 2-hydroxyethyl methacrylate produces a dental adhesive with better adhesion and antibacterial properties than the combination of bisphenol A glycidyl methacrylate and 2-hydroxyethyl methacrylate.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
