Description

an oral appliance

technical field

The invention belongs to the technical field of oral medical devices, and in particular relates to an oral appliance.

Background technique

Lockbite is a malocclusion of the posterior teeth, where individual or most posterior teeth of the upper jaw are locked to the buccal side of the lower posterior teeth, or individual or most posterior teeth of the lower jaw are locked to the upper posterior teeth On the buccal side, it is a lockbite deformity. Ortholocking is the lingual slope of the tongue tip of the upper posterior teeth and the buccal slope of the buccal cusp of the lower posterior teeth. There is no occlusal contact on the occlusal surface. More common. In severe positive lockbite, the teeth tilt and elongate very seriously, which not only causes the pair of teeth to lose their occlusal function, but also causes severe wear and tear on them, causing symptoms such as tooth sensitivity and even root canal inflammation, which eventually leads to tooth extraction, and also leads to Temporomandibular joint disorders. In the traditional method, the teeth in front of the maxillary first molars can be directly lowered vertically by implant screws, but for the second molars, the area of the palatal bone plate corresponding to the second molars is very thin and cannot be implanted. Therefore, it is necessary to use force to correct the ortholocking of the second molars. Due to the thick roots of the mandibular posterior teeth, if the implant screws cannot be implanted between the roots, and the external oblique line is relatively steep, the implant screws cannot be directly used to pull the vertical teeth. Straight lock teeth.

Contents of the invention

The invention provides an orthodontic arch expander. The oral orthodontist has a simple structure, is easy to operate by a doctor, can quickly correct the interlocking phenomenon of mandibular posterior molars, and is suitable for mild posterior interlocking.

To achieve the above object, the present invention adopts the following technical means.

An oral orthodontic device, comprising a maxillary belt ring, a connector, a connecting rod and a guide plate, the upper jaw belt ring is used to be set on the maxillary molars, and the connecting rod is used to connect the upper jaw belt rings on the left and right sides, The shape of the connecting rod is consistent with the shape of the dental arch; the connecting piece includes a fixing post, a connecting cross bar and a fixing nut, the fixing post is fixed on the lingual side of the maxillary belt, and the fixing post is provided with a connecting cross bar Matching through holes, the two ends of the connecting cross bar are provided with external threads that match the fixing nuts, the guide plate is provided with a connecting hole matching the connecting cross bar, the connecting cross bar passes through the connecting hole, and passes through The fixing nut is fixed.

Further, the side surface of the guide plate abutting against the mandibular teeth is provided with a curved surface matching the lingual side of the mandibular teeth. This structure can make the force applied to the mandibular teeth uniform when the guide plate pushes the mandibular teeth outward. Improve the correction effect and correction efficiency.

Further, the guide plate is also provided with a silicone gasket, which is fixed on the side of the guide plate that abuts against the lingual side of the mandibular teeth, and the silicone gasket can prevent the guide plate from pushing the mandibular teeth outward. , damage the mandibular teeth.

Further, the guide plate is made of hard resin material.

Further, the upper jaw belt ring, connecting rod and connecting piece are titanium alloy components.

The beneficial effects of the present invention are as follows: the present invention sets a guide plate, and corrects the patient's rear molar interlocking through the external push of the guide plate to the mandibular molars; the present invention does not need to use implant nails and rubber bands for traction, which is convenient for doctors to operate. The comfort level of the patient is improved to a certain extent; the present invention is applicable to mild posterior molar interlocking.
