The invention relates to the technical field of oral treatment equipment, and discloses a positioning device for oral implant surgery and a surgical path planning method, wherein the positioning device for oral implant surgery includes an upper dentition positioning component, a lower dentition positioning component and a visual Sensor; the upper dentition positioning assembly includes a first dental template and a first visual marker, the first dental template is used to fit the upper dentition, the first visual marker is connected to the first dental template, and Out of the oral cavity; the lower dentition positioning assembly includes a second dental template and a second visual marker, the second dental template is used to fit the lower dentition, and the second visual marker is connected to the second dental template plate and protrudes out of the mouth; the lens of the vision sensor faces the surgical field. The positioning device uses a machine vision system to convert the three-dimensional model in the occlusal state, and can perform preoperative measurement and intraoperative monitoring of the patient's jaw position, improving surgical safety.
Description
technical field [0001] The invention relates to the technical field of oral treatment equipment, in particular to a positioning device and a surgical path planning method for oral implant surgery. Background technique [0002] The main purpose of oral implant treatment is to restore the patient's masticatory function. In order to ensure healthy and stable implant osseointegration and normal and long-lasting masticatory ability, the design of implant placement and the production of restorations must follow reasonable biomechanical principles. In order to restore the patient's occlusal force, it is necessary to determine the occlusal relationship (also known as the jaw relationship), that is, the mutual positional relationship between the upper and lower dentition. An abnormal occlusal relationship can lead to masticatory dysfunction. Patients with malocclusion have poor fit between the upper and lower teeth, and often swallow the food without grinding it completely, which af...
