Problems solved by technology

[0002] At present, in the process of stomatology teaching, oral models are required for dental teaching. Most of the current oral model teeth are integrally formed on the upper jaw model and the lower jaw model, and the rear part of the teeth can be inserted into the upper jaw by interference fit. The model and mandibular model are used for tooth extraction learning. This interference fit me

Embodiment

[0024] Embodiment: a kind of oral cavity model for practice, comprises maxillary articulator 20, mandibular articulator 30, model maxilla 70, model mandibular 60 and model tooth 67, and described maxillary articulator 20 can be rotated and is installed on the mandibular of setting angle On the articulator 30, the model upper jaw 70 is fixedly installed on the upper jaw articulator 20, and the model lower jaw 60 is fixedly installed on the lower jaw articulator 30. The model upper jaw 70 and the model lower jaw 60 are provided with several alveoli, and the model teeth 67 are one by one. Correspondingly inserted in each alveolar, and the model teeth 67 are detachably fixedly connected to the alveolar through at least one of a buckle structure and a connecting piece. Any model tooth 67 of the oral cavity model can be installed and disassembled quickly, and is easy to use. The model tooth 67 is 32 teeth or 28 teeth. The side wall of the root of the model tooth 67 is provided with ...

Abstract

The invention discloses an oral cavity model for practice. The model comprises an upper jaw occluder, a lower jaw occluder, a model upper jaw, a model lower jaw and model teeth. The upper jaw occludercan be mounted on the lower jaw occluder in a manner of rotating and keeping a set angle, the model upper jaw is fixedly mounted on the upper jaw occluder, and the model lower jaw is fixedly arrangedon the lower jaw occluder. A plurality of tooth grooves are formed in the model upper jaw and the model lower jaw, the model teeth are inserted into the tooth grooves in a one-to-one correspondence manner, and the model teeth and the tooth grooves are detachably and fixedly connected through at least one of a buckle structure and a connecting piece. The oral cavity model is simple in structure, high in simulation degree and stable in structure, facilitates various operations in the practice process and is beneficial for students to improve the operation skills.

Description

technical field [0001] The invention relates to an oral cavity model, in particular to an oral cavity model for practice. Background technique [0002] At present, in the process of stomatology teaching, oral models are needed for dental teaching. Most of the current oral model teeth are integrally formed on the upper jaw model and the lower jaw model, and the latter part of the teeth can be inserted into the upper jaw by interference fit. The model and mandibular model are used for tooth extraction learning. This interference fit method, after long-term insertion and extraction learning, is easy to maintain a stable connection due to wear and tear. The model teeth are easy to fall off and lost, which is inconvenient to use. The models do not have a tongue, which makes the students not pay enough attention to the tongue during the practice, and it is easy to damage the patient's tongue during the actual dental treatment. Contents of the invention [0003] In order to over...
