Individualized mandibular navigation and registration guide and its registration method

Abstract

The invention belongs to the field of medical technology, in particular to an individualized mandibular navigation registration guide plate and a registration method thereof, comprising a guide plate and a gypsum model of mandibular teeth, the bottom surface of the guide plate is designed with occlusal grooves, and the two end surfaces of the guide plate are provided with There are wings, the sides of the guide plate and the surface of the wings are provided with registration mark points, and the plaster model of the mandibular teeth is scanned by laser to form a virtual mandibular tooth model, and its dentition partially replaces the one reconstructed from the imaging data. The dentition part of the virtual mandible model is used to make the occlusal groove of the guide plate; in the present invention, the shape of the occlusal groove matches the shape of each patient’s mandibular teeth, and at the same time, the registration marker points are discretely distributed on the sides of the guide plate and the wing plate, For system registration, there is no need to implant titanium nails in the patient's mandibular alveolar bone as a registration reference point, no invasive operation, no need for a second CT examination, which not only reduces the damage to the patient, but also facilitates the doctor's operation, practical Strong.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to an individualized mandibular navigation and registration guide plate and a registration method thereof. Background technique [0002] The field of craniofacial surgery includes neurosurgery, oral and maxillofacial surgery, ophthalmology, otolaryngology, head and neck surgery, plastic surgery and many other disciplines. Its common treatments include malignant tumor resection, compound trauma, and deformity restoration. . Due to the proximity to the cranium, the complex anatomical structure, and the close relationship between treatment needs and appearance, precise intraoperative operations must be performed with minimal trauma. Traditional technical methods have been unable to meet the needs of treatment and professional development in terms of preoperative prediction and simulation, surgical execution accuracy, and operational stability. Reluctantly doing so will gr...

Problems solved by technology

Although the implantation of titanium nails is performed under local anesthesia, it is an invasive operation for patients. Some patients will feel discomfort or even strong pain after the implantation of titanium nails, and need to take painkillers, and the CT examination again is also difficult. Can cause secondary radiation damage to the patient
