A sensing system and method for detecting occlusal force of 3D printed implants

Abstract

The invention belongs to the technical field of medical diagnosis in the medical oral cavity, and relates to a sensing system and method for detecting the 3D printing implant tooth biting force. Miniature flexible pressure sensors are uniformly arranged in the 3D printing implant teeth for sensing the biting force; an active RFID embedded into the dental crown is used for transmitting the signals;a set of tooth biting force measuring warning system is formed; a titanium slurry nanometer coating is covered on the periphery of the tooth roots of the 3D printing implant teeth; a pressure sensitive material is distributed and plated on the outer side of a planting body; the pressure sensitive material is connected to the active RFID chip in the tooth crown; data is transmitted to the mobile terminal end and the like through the RFID chip. The accurate quantitative basis is provided for the service life of the 3D printing implant teeth, so that the medical care health care equipment is transferred from sickrooms or hospitals to families; the unhealthy life mode and the aging people cost burden can be reduced.

Description

technical field [0001] The invention belongs to the technical field of medical diagnosis of medical oral cavity, and in particular relates to a sensing system and method for detecting the occlusal force of 3D printing implant teeth. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] 3D printed dental implants are a good way to repair missing dentition, and are widely accepted by the majority of patients due to their good stability and appearance. In a true sense, no matter whether it is biochemically bonded to fibers or osseointegrated, bone modules and implant dentures cannot form periodontal ligament tissue, so it lacks the buffering function of periodontal ligament for natural teeth. And the sensory ability of nerve endings, it is very easy to be traumatized by excessive bite force without knowing it. For example, in the case of occlusal overload, the occlusal forces that the implants are subjected ...

AI Technical Summary

Problems solved by technology

[0010] At present, after 3D printing implant restoration, there is no postoperative maintenance technical problem caused by weak sensation; it is easy to cause secondary trauma, but it cannot be sensed; it cannot assist professional dental implant doctors after implantation, and in the event of an accident, the doctor is more Diagnose corresponding diseases relatively visually, and make corresponding treatment; moreover, it is impossible to provide quantitative data prompts for the patient's response to jaw trauma and periodontal inflammation caused by the chewing process, and to apply reasonable chewing pressure; As the implementer of the bite force, the patient cannot participate in the prevention, diagnosis and treatment, which makes the treatment effect poor; the lack of professional knowledge between doctors and patients makes the patient's unconscious compliance poor; the data cannot be collected in time , preserved and sorted out, so that there is almost no reason for the implant to fall off; the existing sensing devices for occlusal detection of 3D printed implants cannot provide guidance for practical applications in terms of theory and application
