The invention belongs to the technical field of medical diagnosis in oral medicine, and relates to a sensing system and method for detecting biting force of a 3D printing dental implant. A titanium plasma nano-coating is smeared around the 3D printing dental implant and a micro-nano sensor is wrapped in the inner layer of the titanium plasma nano-coating; the 3D printing dental implant, which is integrated with the micro-nano sensor, can sense data and signals of the biting force; the data and signals are saved in cloud by virtue of a cloud storage database of intelligent equipment; three-dimensional data of the 3D printing dental implant is acquired through a point cloud data reverse engineering in the cloud storage database of the visible intelligent equipment; and the data and signals in the cloud are analyzed by virtue of the visible intelligent equipment, so that a prevention system for handling the service life of the 3D printing dental implant with the simultaneous participationof a doctor and a patient can be constructed. With the application of the sensing system and method provided by the invention, the attitude to the service life of the 3D printing dental implant is improved; the transfer of medical care equipment from wards or hospitals to homes is achieved; and non-healthy life styles and cost burden of aging populations are reduced.
