Individual lower jawbone navigation registration guide plate and registration method thereof

Abstract

The invention belongs to the technical field of medical care, and particularly relates to an individual lower jawbone navigation registration guide plate and a registration method thereof. The individual lower jawbone navigation registration guide plate comprises a guide plate and a mandibular tooth plaster model, wherein the a biting groove is designed in the bottom surface of the guide plate; wing plates are arranged on the end surfaces of two sides of the guide plate; registration mark points are arranged on the side of the guide plate and the surfaces of the wing plates; and the mandibulartooth plaster model forms a virtual mandibular tooth model through laser scanning, and dentition parts can replace that of the virtual mandibular tooth plaster model reconstructed by imaging data, and are used for making the biting groove of the guide plate. The shape of the biting groove cooperates with that of the mandibular teeth of each patient, and besides, discrete-distribution registrationmark points are formed on the sides of the guide plate and the wing plates, so as to register the system; and titanium nails do not need to be transplanted in mandibular alveolar bone of the patientto be used as registration reference points, wounded operation is not needed, and secondary CT examination does not need to be performed, so that the damage to the patients can be reduced, the operation is convenient to the doctors, and the practicality is high.

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
