3D printing-based mandibular deviation measuring instrument

Abstract

The present invention discloses a 3D printing-based mandibular deviation measuring instrument. The mandibular deviation measuring instrument comprises a U-shaped measuring instrument body; the measuring instrument body is matched with the dental arch; the tooth fitting surface of the measuring instrument body is provided with tooth holes matched with the dentition; and the arc-shaped outer end surface of the measuring instrument body is provided with a graduated scale. The measuring instrument is designed based on a cusp and fossa relationship of the maxillary dentition, and the outer end surface of the measuring instrument is provided with the graduated scale, so that the graduated scale can intuitively measure the mandibular deviation distance of a patient. The mandibular deviation measuring instrument is printed with a 3D printing technology, and the maxillary plane and the face centerline of the patient are obtained by a three-dimensional model to determine the offset distance of the mandible on the coronal centerline. The measuring instrument is used for instructing the mandibular deviation patient to perform rehabilitation training so as to reduce complications of the patient, increase the rehabilitation exercise compliance of the patient, reduce the doctor-seeing frequency, reduce the workload of medical care personnel and improve the life quality of the patient.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a jaw deviation measuring instrument based on 3D printing. Background technique [0002] 3D printing (3DPrinting) technology is a new type of manufacturing technology produced and developed in the late 1980s. Its principle is to use three-dimensional computer-aided design data to accumulate materials layer by layer through a 3D printer, and finally prepare a solid prototype. molding technology. 3D printing can directly and quickly print the designed virtual objects into prototypes or manufactured parts with certain functions, which has the advantages of accuracy and automation. At present, 3D printing technology has been widely used in orthopedics, rehabilitation medicine, oral and maxillofacial surgery and other biomedical fields. The causes of partial jaw deformity are more complex, mainly divided into two categories: congenital and acquired. Among the congenital facto...

Problems solved by technology

However, in searching the existing literature, there is no mention of a simple, intuitive, and visual assessment tool for patients

The effect of patients' rehabilitation exercises often depends on the evaluation of medical staff, which not only increases the number of visits of patients, increases the possibility of complications, but also increases the workload of clinical medical staff, making patients adhere to the compliance of rehabilitation training and life. reduced quality

[0004] At present, there is still no clinically applicable tool for self-rehabilitation evaluation of patients with partial jaw deformity
