Polymerizable monomer composition for dental restorations and its method of manufacture and use

Abstract

A polymerizable monomer composition for dental restorations, and methods for making and using the same, are provided. [Solution] The present invention provides a polymerizable monomer composition for dental restoration, and its manufacturing method and use. The polymerizable monomer composition comprises a combination of a polymerizable monomer, an initiator, and a crosslinking agent. The addition of a crosslinking agent increases the double bond conversion rate of the polymerizable monomer composition and reduces its residual rate. Adding the crosslinking agent to a resin ceramic restorative material can increase the strength and toughness of the resulting resin ceramic restorative material. Furthermore, when used in dental restoration, the resin ceramic restorative material can maintain a good shape regardless of the processing process or when worn by a patient. Furthermore, the resin ceramic restorative material has a reduced water absorption and dissolution value and an improved mechanical strength, thereby extending its service life and meeting market needs.

Description

[Technical field]

[0001] [CROSS REFERENCE TO RELATED APPLICATIONS] This application claims priority to a Chinese patent application filed with the China Patent Office on July 21, 2021, with application number 202110826681.7, entitled "Polymerizable monomer composition for dental restoration and its manufacturing method and use," the entire contents of which are incorporated herein by reference.

[0002] The present invention is in the field of composite materials, and specifically relates to a polymerizable monomer composition for dental restorations, and its preparation and use. [Background technology]

[0003] At present, digital restoration based on CAD / CAM technology has become an important development direction in oral restorative science. A variety of oral restorations can already be processed and manufactured by digital means. Among the dental restorative materials cut by CAD / CAM, ceramic materials are the most widely used materials in CAD / CAM technology due to their excellent mechanical properties, optical properties, and biocompatibility. However, ceramic materials are very brittle and prone to porcelain crack phenomenon, which causes great wear on the cutting bit, and also causes serious wear on the jaw teeth due to their high hardness. Resin materials occupy a large proportion in CAD / CAM cutting due to their low price, good toughness, easy machining and cutting, short repair cycle, and no wear on the jaw teeth. However, resin materials cannot be used as permanent restorative materials due to their low strength, poor wear resistance, and short service life.

[0004] Resin ceramic restorative materials combine the high strength of ceramic materials with the good toughness of resin materials, but there are two problems: (1) Resin ceramic restorative materials inherit the biocompatibility of ceramic materials to a certain extent, avoid the disadvantages of ceramic materials such as high strength, easy wear of jaw teeth, and easy brittle fracture, and also have significantly improved mechanical properties compared with resin materials, but in actual dental restorations, the mechanical performance of resin ceramic composite materials cannot reach a completely satisfactory level; (2) The high water absorption value of resin ceramic restorative materials will reduce the mechanical properties of the materials, cause microleakage, reduce the thermal stability of the materials, cause the precipitation of unreacted monomers in the materials, and even cause hydrolysis of polymer segments, ultimately shortening the service life of the materials.

[0005] Patent Document 1 discloses a polymerizable monomer composition for dental materials having a cured product that simultaneously achieves high toughness and rigidity, a composition for dental materials containing the polymerizable monomer composition for dental materials, and a cured product thereof with high mechanical properties. In the present invention, the polymerizable monomer composition for dental materials contains a urethane acrylate compound and a polymerizable compound, and the urethane acrylate compound is obtained by reacting a specific hydroxyacrylate with a diisocyanate, and the diisocyanate is formed by a bond between a methylene group, in which a hydrogen atom can be replaced by a hydrocarbon group, and two isocyanate groups by a divalent aromatic hydrocarbon group having 6 to 9 carbon atoms or a divalent crosslinked cyclic hydrocarbon group having 6 to 9 carbon atoms. The polymerizable compound contains at least one polymerizable group selected from a methacryloyl group and an acryloyl group. Patent Document 2 discloses a dental hardenable composition, in which the resin monomer and the filler are contained in a weight ratio of 10:90 to 70:30, and 0.01 to 10 parts by weight of a polymerization initiator and 0.001 to 1 part by weight of a terpenoid compound are contained relative to 100 parts by weight of the resin monomer. By adding a terpenoid compound as a chain transfer agent, the thermal polymerization rate of the resin monomer, which has a high thermal conductivity among the components contained in the dental hardenable composition and begins to polymerize rapidly due to heat, is slowed down, and thus uniform thermal polymerization is performed, the occurrence of microscopic and macroscopic strains is suppressed, and the occurrence of cracks and chips can be suppressed. In addition, the addition of this chain transfer agent suppresses the foaming of the low-boiling resin monomer, so that the inclusion of air bubbles can also be suppressed. However, the addition of the chain transfer agent and the design of the polymerizable monomer cannot improve the mechanical properties such as bending strength and hardness of the final ceramic resin material, and therefore cannot effectively improve the service life of the material.

[0006] Patent Document 3 discloses a thermosetting composite resin block, which is composed of a polymerizable resin containing an ethylenically unsaturated group, an initiator that dissolves in the resin and is activated at a temperature of about 100°C to about 150°C, and an inorganic filler mixed with the resin, and the bending strength, wear resistance, and aesthetic properties of the resin block are greatly improved. In addition, due to the high decomposition temperature of the initiator, it will not decompose prematurely into monomers under normal processing conditions, and the blank will not be discolored by the decomposition process. However, the improved mechanical strength is only 200 MPa, which cannot fully meet the needs of patients.

[0007] Therefore, the development of a polymerizable monomer composition to improve the mechanical properties, biocompatibility, and life span of resin ceramic restorative materials is an urgent technical problem for those skilled in the art to solve. [Prior art documents] [Patent documents]

Using a tensile testing machine, a three-point bending test was performed under the conditions of a support interval of 12 mm and a crosshead speed of 1.0 mm / min, and the average values ​​of 10 samples were used for evaluation. (2) Vickers hardness: Using 2000 grit sandpaper, the test surface of the resin ceramic restorative material after curing was polished with water polishing to ensure that the surface of the sample was smooth, and then tested using a Vickers hardness tester: the test force value of "2" was selected, and three different positions of the resin ceramic restorative material were measured, and the average value was obtained. (3) Wear resistance: Using the machining equipment, the resin ceramic restorative material after curing was processed to produce a sample with a diameter of (10±0.1)×(6±0.5)mm. Three samples of various materials were produced, pre-polished with 400-grit sandpaper, the wear load was 22N, and the number of friction times was 75 times. The sandpaper was removed, the tray, the kinetic friction member, the sample, and the fixture were rinsed and wiped dry. Abrasives were used for pre-polishing, and the wear load was 172N, and the sample was rubbed 150 times. After cleaning, it was weighed and recorded as the mass of the sample before polishing m1. A cow's tooth was used to rub the sample 1500 times with a wear load of 172N, and after cleaning, it was weighed and recorded as the mass of the sample after polishing m2. A total of three samples were worn, and the kinetic friction member and the abrasive were replaced before each wear, and the sample density ρ was measured before the measurement, and the volume loss of the sample was ΔV=(m1-m2) / ρ. (4) Water absorption and dissolution values: The hardened resin ceramic restorative material was processed into samples with a size of φ(15±1)×(1.0±0.2) mm, and the surface of the sample was polished by wet grinding with 2000-grit sandpaper. The diameter and thickness of the sample were measured, and the volume V of the sample was calculated. The sample was then placed in a desiccator and dried in an oven at 37°C. After 24 hours, the samples were taken out and weighed one by one on a 1 / 10,000 balance with an accuracy of 0.1 mg. The above steps were repeated until a constant weight was reached, and recorded as m1. The constant weight sample was placed in a zippered storage bag containing about 30 mL of pure water, and immersed in a thermostatic water bath at 37±1°C. After immersion for 7 days, it was taken out, rinsed with clean water, and then the surface was dried before testing, weighed on a 1 / 10,000 balance, and recorded as m2. Finally, it was placed in a 37°C oven to dry for 14-21 days until a constant weight was reached, and weighed on a 1 / 10,000 balance, and recorded as m3. Water absorption value ρ ws =(m2-m3) / V, solubility value ρ sl =(m1-m3) / V.

[0079] In addition, the water absorption values ​​of the resin ceramic restorative materials obtained in Examples 1 to 10 were 11 to 15 μg / mm 3 , the dissolution value is 0.8-1.2μg / mm 3 These values ​​are obviously lower than the water absorption and dissolution values ​​of the resin ceramic restorative materials obtained in Comparative Examples 1 and 2, which demonstrates that the resin monomer residue in the resin ceramic restorative material obtained by the present invention is low.
