When the mandibular leading amount of the patient is larger, the power arms 21 with different lengths can be designed according to the leading amount, and the whole power arm 21 with different lengths can be directly replaced
The pad 2 can also be used for realizing the mandibular step-by-step front guiding by adding glue at the front end of the power arm 21. Because of different front guide amounts and different front tooth depression amounts, a third buccal tube is arranged on the first metal coping 1 and positioned on the buccal side of the second front molar or the second deciduous molar, the third buccal tube also has certain axial inclination, and is different from the axial inclination of the first buccal tube, and the main arch wire can be fixed on buccal tubes with different axial inclinations so as to realize different front tooth depression amounts.
The utility model discloses a use method specifically does: firstly carrying out occlusion reconstruction, determining mandibular leading amount and occlusion records, producing a personalized appliance, then installing an upper jaw appliance and a lower jaw appliance on an upper jaw and a lower jaw in the oral cavity, and then installing the upper jaw appliance and the lower jaw appliance
The pad 2 is arranged on the first metal combined crown 1, then an orthodontic bracket is arranged, and finally the main arch wire is arranged in the corresponding buccal tube and the bracket. When the mouth is closed, the lower jaw blocking arm slides forwards and upwards along the upper jaw power arm, and finally the upper jaw blocking arm and the upper jaw power arm form a locking effect to force the lower jaw to be in a forwards extending position, so that the lower jaw is corrected in a backwards retracting mode. The problem that the upper and lower jaws are not adjusted even if the front lower jaw is cut to be incised and the problem that the rear teeth do not establish occlusion contact after functional correction are finished due to the fact that the lower incisor lip is inclined can be effectively avoided by matching with the process of adduction and depression of the front teeth in the process of guiding the lower jaw forwards, and the fact that the angle from the lower jaw forwards to the ANB is a normal value can be well achieved. In addition, if necessary, the planting nail can assist the posterior teeth to be pressed down to control vertically, so the utility model is also suitable for high-angle cases; during the process of depressing anterior teeth, the patient is taken off during the re-diagnosis
Cushioning, gradually regulating and grinding
Thickness of pad to keep anterior teeth normally covered
When the mandibular leading amount of the patient is large, the length of the patient can be designed to be different according to the leading amount
The cushion 2 and the power arm 21 realize the mandibular step-by-step leading. At the later stage of functional correction, when the combined gasket is ground to a thinner thickness, the combined gasket is removed
And (3) replacing a metal power arm with a cushion, inserting the metal power arm into the accessory tube 9, continuing correcting and maintaining, removing the functional corrector after a period of time, continuing fixing orthodontic treatment, closing the residual tooth extraction gap, and adjusting occlusion. Because the double-stage correction is carried out simultaneously, the treatment time can be greatly shortened, and the seamless connection of occlusion, leading and holding stages of the posterior teeth can be smoothly established, so that the leading effect is more stable.
Example 2
As shown in fig. 6 to 9, this embodiment is basically the same as embodiment 1, and only the positions of the power arm 21, the stopper arm 41, and the accessory tube 9 are changed, and the power arm 21, the stopper arm 41, and the accessory tube 9 are disposed on the tongue side. Specifically, the power arm 21 is specifically arranged at the lingual side close to one end of the second premolar or second deciduous molar, the blocking arm 41 is arranged at the lingual side of the second metal coping 4 and is matched with the power arm 21, specifically, when in occlusion process, the power arm 21 at the upper jaw is matched with the blocking arm 41 at the lower jaw, the lower jaw slides to the front upper side along the inclined plane of the power arm 21 at the upper jaw to realize the forward guiding of the lower jaw,
the pad is in occlusal contact with the posterior mandibular teeth to further stabilize the anterior mandibular position and ensure that the patient eats normally.
The above is only the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and the utility model should be covered in the protection scope of the present invention.
