Problems solved by technology

However, composite resins also have certain problems. The mechanical strength is not high enough to be used on the heavily loaded posterior teeth, the wear resistance is also poor, and the volume shrinks greatly when polymerization and curing occur. These limit the application range of composite resins. and service life

Embodiment 1

[0044] A modified silane coupling agent is prepared as follows:

[0045] 3-Chloropropyltriethoxysilane and triethylamine (the molar ratio of 3-chloropropyltriethoxysilane and triethylamine is 1:1) were added to a chamber equipped with a reflux device, a thermometer and a dropping funnel. In the four-necked flask, start the strong stirrer, dropwise add isopropyl 3-aminocrotonate (the molar ratio to 3-chloropropyltriethoxysilane is 1:1) into the flask within 30min, and gradually heat up to 80 ℃, reflux reaction for 5h; suction filtration to remove amine salt precipitation, the filtrate is purified by vacuum distillation, that is, modified silane coupling agent; the whole reaction process is nitrogen protected and strictly waterproof. The structural formula of the modified silane coupling agent is:

Abstract

The invention discloses a dental restoration material for stomatology and a preparation method thereof, and relates to the field of medical materials. The dental restoration material for oral science comprises: base resin, the above-mentioned base resin includes at least one of Bis-GMA and UDMA; filler, the above-mentioned filler includes modified silane coupling agent modified barium glass powder, modified silane coupling At least one of agent-modified micro-silica powder; photoinitiator. The dental restoration material prepared by the present invention has excellent mechanical strength, strong wear resistance, and low polymerization shrinkage; and the water absorption and solubility are significantly reduced, thereby enhancing the service life of the restoration material, reducing its toxicity in use, and reducing the risk of periodontitis Incidence, expanding the scope of use of restorative materials.

Description

technical field [0001] The invention belongs to the field of medical materials, and in particular relates to a tooth restoration material for oral science and a preparation method thereof. Background technique [0002] With the continuous development of medical materials and technologies in China, more and more advanced materials are being continuously applied. The number of patients with oral diseases continues to increase, and the application of high-tech materials in advanced materials has a very good clinical effect. Especially in the use of high-tech materials as fillings in tooth defects, great achievements have been made. Restorative dentistry is the preparation of teeth based on the removal of damaged or severely weakened tooth tissue, according to the principles of retention, resistance and protection of the pulp-dentin organ, and finally restores its original shape with specific materials through a certain procedure. and function. The main cause of tooth loss is...
