Method for improving dentin bonding with negative pressure

The invention relates to a method for improving dentin bonding with negative pressure, and relates to the technical field of oral tooth restoration. According to the method, the bonding surface of a tooth to be bonded are conventionally treated; a bonding agent is applied; with a negative pressure generation device, negative pressure is generated at the bonding surface of the tooth to be bonded through a suction nozzle; the pressure is changed to natural atmospheric pressure (normal pressure) or elevated pressure; and the process of negative pressure to normal pressure or elevated pressure can be repeated. With the negative pressure-normal pressure or elevated pressure process, the bonding agent applied on the bonding surface of the tooth to be bonded can more deeply penetrate into the deep layer of dentin, such that the quality of a mixed layer is improved. Therefore, the adhesion and durability of the bonding agent on the tooth can be improved. 种负压改善牙本质粘接的方法，属于口腔牙体修复技术领域。待粘接牙齿粘结面常规处理，涂布粘接剂后，利用产生负压装置通过吸嘴使待粘接
