Description
Technical Field
The invention relates to the field of teaching auxiliary tools, in particular to a use method of a centering relation position demonstration device.
Background
Fig. 1 is a schematic diagram of the bone structure of a human head, and as shown in fig. 1, the central relationship is the positional relationship between a lower jaw 101 and an upper jaw 102, and the positional relationship between a condyle 103 in a glenoid fossa. When the maxillary and mandibular teeth do not define a stable maxillomandibular relationship, the only stable connection available between the maxillomandibular teeth is the positional relationship of the condyles 103 to the glenoid fossa. Therefore, the median relationship can be clinically used to establish median occlusion. There are many definitions of The median relationship, and seven versions are already defined in "The Glossaryof Prosthodontic Terms". The current latest version of the definition of the centering relationship is: the condyles are located at the uppermost and foremost position of the glenoid fossa.
For complex clinical cases such as occlusal reconstruction, determining median occlusion, determining non-median occlusion, and determining vertical distance are the three most important factors in occlusal reconstruction. With determination of median occlusion being the most central problem. When the residual upper and lower jaws can not determine the stable occlusion relation of the upper and lower jaws or the original occlusion relation has pathological problems, a new median occlusion relation needs to be established again. That is, the most important clinical meaning of the median occlusal relationship is to guide the doctor to determine the median occlusal relationship in complicated cases such as occlusion reconstruction.
For example, when studying and treating "adult mandibular posterior malocclusion", the different states of the mesial relation position and the mesial occlusion cause a shift in the position of the condyles 103, and if the shift in the position of the condyles 103 can be visually displayed, it can bring clear and intuitive feelings to the oral medical students and oral clinicians for understanding and analyzing "adult mandibular posterior malocclusion".
In the process of oral medicine teaching and training, the used teaching aid is usually a common oral orthopaedic model sold in the market, or the theoretical position of the central relation position and the central occlusion relation is displayed by utilizing the occlusal frame, but the condylar position of the common oral orthopaedic model sold in the market is usually fixed and cannot be changed, and the occlusal frame is used for converting and displaying the central relation position and the central occlusal position according to a specific tooth plaster model, so that the displaying of the condylar position by the occlusal frame is not intuitive.
