The application discloses a multiple controlled-release
drug-loaded
coating modified anti-
heterotopic ossification artificial
temporomandibular joint prosthesis and a preparation method thereof, and comprises the following steps: surface treatment of a biomimetic artificial
temporomandibular joint prosthesis;
dopamine assisted co-deposition is adopted to sequentially form a DF-HA self-assembled nanosphere
coating and a
meloxicam liposome drug-loaded
coating on the surface of the biomimetic artificial
temporomandibular joint porous titanium prosthesis; and RGD is grafted on the surface of the
meloxicam liposome drug-loaded coating by chemical natural deposition, and the anti-
heterotopic ossification artificial temporomandibular
joint prosthesis is obtained. The artificial temporomandibular
joint prosthesis is modified by active drug-loaded
meloxicam liposomes on one hand, and the artificial temporomandibular
joint prosthesis is modified by RGD-DF-HA layered drug loading on the other hand, long-term slow release and programmed release of drugs are realized, anti-inflammatory effects are achieved, the purpose of treating and preventing
heterotopic ossification after artificial
joint replacement is achieved, long-term stability of artificial
joint replacement is beneficial, early prevention, intervention, service life of the artificial joint prosthesis is improved, and the
life quality of patients is improved.
