Embodiment Construction
[0043] In order to illustrate the technical features of the solution more clearly, the solution will be described below through specific implementation modes.
[0044] see figure 1 , a method for detecting the occlusal accuracy of oral restorations, by measuring the data of the maxillary teeth and condyle (including the length from the mesial incisor angle of the maxillary central incisor to the condyle and the length from the mesiobuccal tip of the bilateral maxillary molars to the condyle) distance), and the slope data of the protruding and lateral incisions, transfer the occlusal relationship of the upper and lower jaws to the virtual frame, and design and manufacture the occlusal point of the restoration. The specific steps are as follows:
[0045] Step S1: Use a 3D oral scanner to scan the maxillary and mandibular dentition, generate a three-dimensional image on the computer through modeling software, and construct an occlusal model based on the scanned image;

According to the detection method for the occlusion precision of the dental restoration and the occlusion booster thereof, the occlusion relation between the upper jaw and the lower jaw is transferred to a virtual frame by measuring data of maxillary teeth and condyle processes and inclination data of protraction and lateral incisions, design and manufacturing of occlusion points of the restoration are carried out, and the occlusion precision of the dental restoration is detected. The method comprises the following specific steps: scanning an upper jaw dentition and a lower jaw dentition by using a 3D oral cavity scanner, generating a three-dimensional image through modeling software, and constructing an occlusion model according to the scanned image; in the mouth, blue occlusion paper is used for recording lateral movement, red occlusion paper is used for marking center movement, and red occlusion point positions and blue occlusion point positions are scanned respectively and imported into a computer. According to the detection method for the occlusion precision of the dental restoration and the occlusion booster thereof, provided by the invention, the occlusion precision of the existing dental restoration can be detected, and the occlusion movement of a patient can be accurately simulated, so that the occlusion point in the manufacturing process of the restoration can be accurately designed, and the processing precision of the restoration can be indirectly improved.
Description
technical field [0001] The invention belongs to the technical field of medical stomatology, and in particular relates to a method for detecting the occlusal precision of an oral prosthesis and an occlusal booster thereof. Background technique [0002] As the design of oral restorations becomes more and more complex, the requirements for machining precision are getting higher and higher, and the application of computer scanning technology is becoming more and more extensive. The machining accuracy of restorations directly affects the oral health of patients and the service life of restorations. The machining accuracy of the restoration is greatly affected by the occlusal accuracy. [0003] The production of traditional occlusal points is to record the occlusal relationship through silicone rubber, and transfer it to the mechanical frame through the facebow to simulate the occlusal relationship in the patient's mouth, so as to make the occlusal point. This method cannot repli...
