Problems solved by technology

[0003] The present invention aims to solve the problem that existing adhesives cannot satisfy the bonding of oral dental implants and their upper restorations such as porcelain crowns and porcelain fixed bridges due to the existence of bonding strength, elastic modulus and biological safety performance. As a result, artificial root implants have the defect of traumatic impact on alveolar bone tissue due to chewing stress during the chewing process, and provide an oral adhesive with a low elastic modulus that can buffer the traumatic impact of chewing stress on alveolar bone tissue.

Abstract

The invention relates to a bonding agent used between an oral implant and an upper prosthesis, which comprises a powder agent and a liquid agent. In the powder agent, ultrafine fully vulcanized powder rubber or plastic shock resistant modifier MBS or processing modifier ACR is prepared by respectively mixing organic resin, padding, a reducing agent and other auxiliary components or blending powder prepared from zinc oxide, magnesium oxide, calcium fluoride, tin fluoride and aluminum oxide (trace). The liquid agent comprises a resin substrate, an adhesive monomer, a thinning agent, an oxidizing agent, a polymerization inhibitor or polyacrylic acid, and the balance water, wherein the mass fraction of polyacrylic is 30%-48%. The using process comprises the following steps: weighing the powder and the liquid according to the proportion of 1:1, uniformly mixing the powder and the liquid into paste, and curing the paste for 3-5 minutes under the condition of room temperature.

Description

technical field [0001] The invention relates to an adhesive used between an oral cavity implant and an upper restorative body, and is particularly suitable for bonding an oral dental implant and its upper restorative body such as a porcelain crown, a porcelain fixed bridge, and the like. Background technique [0002] The artificial tooth root implant and the alveolar bone tissue in oral implant restoration treatment are osseointegrated. In order to reduce the traumatic impact of mastication force on the alveolar bone tissue during mastication, the artificial tooth root implant should have bone tissue matching mechanical properties. Studies have shown that reducing the elastic modulus of denture implants is more conducive to transferring the load to the surrounding bone tissue in the form of compressive stress, which is conducive to maintaining the stability of the interface and improving the biomechanical compatibility of the implant. . At present, the vast majority of imp...
