Description
Technical field
The utility model relates to teaching equipment field, in particular to a kind of remporomandibular joint simulation demonstrating apparatus.
Background technique
Remporomandibular joint is also known as " temporomandibular joint " or " mandibular joint ".By head of mandible and fossa mandibularis ossis temporalis and tuberculum articulare group
At, one articular joint of left and right synthesis, silent and masticatory movement of dehiscing of supervising the cooking.Loosening of articular capsule, side are added by the ligament of medial and lateral
By force.Intracapsular articular disc is in oval, is made of fibrocartilage, three parts before, during and after dividing into.Above be in saddle, it is preceding it is recessed after
It is convex, it is corresponding with the convex-concave profile of tuberculum articulare and mandibular fossa；Recessed face head of mandible, periphery connect with joint capsule below, leading edge
It is connected with the lateral pterygoid muscle tendon for passing through joint capsule.Articular cavity is divided into upper and lower two halves by articular disc.More there is sphenomandibular ligament outside joint
(butterfly spine to mandibular lingula) and stylomandibular ligament (belemnoid to angle of mandible) are reinforced.
The locomotory mechanism of remporomandibular joint is that mandibular joint permission lower jaw above mentions, declines, advancing, retreating and lateral movement.
In opening, silent activity, head of mandible is rotated on the intracavitary edge of mandibular joint by the frontal axis of head of mandible, and mandibular body is shown as down
It drops and above mentions.When making forward and backward movement, articular disc is together with head of mandible around the volume being located in tuberculum articulare in upper joint cavity
Shape axis, makees arc sliding.Lateral movement is then to make to rotate on vertical axis in situ in lower joint space by side head of mandible, and opposite side
Head of mandible moves forward in upper joint cavity together with articular disc.Upper and lower incisor edge distance is up to 50~60mm when dehiscing, forward and
Mobile when lateral movement is 10mm or so.
Fig. 1 is human body head skeleton structural schematic diagram, and shown in Figure 1, the change in location of head of mandible 103 corresponds under temporo
The movement relation in jaw joint, and in Oral preventive medicine and clinical oral doctor to the study understanding process of remporomandibular joint principle
In, it is used in other teaching and communication process in addition to true direct feel can be obtained in the process of dissection study
Apparatus for demonstrating is usually common commercial oral orthopaedics model, or closes frame using tooth to show the theoretical operation original of remporomandibular joint
Reason, but the head of mandible position of common commercial oral orthopaedics model is usually fixed, and cannot be changed, and it is for basis that tooth, which closes frame,
Specific tooth plaster cast is come the positional relationship for showing head of mandible that converts, therefore tooth closes frame for the movement relation of remporomandibular joint
Show it is not intuitive.That is, existing apparatus for demonstrating is generally difficult to intuitively show the movement relation of remporomandibular joint.
