Abstract
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...
