Description
Technical Field
The utility model relates to a tooth appliance field especially relates to a take stealthy just abnormal ware of rescuring of special device.
Background
The expansion of the arch is a common method in orthodontics, and the expansion of the arch has better effects on the situations of narrow arch, undersize upper and lower jaw arches, inward inclination of the upper and lower jaw anterior teeth, shortening of the lower jaw arch anterior segment caused by congenital missing incisors and the like. In the daily orthodontic treatment, the gap required for straightening teeth is generally obtained by an arch expansion operation in the case of a narrow dental arch.
The common arch expansion appliance is a movable appliance or a fixed appliance, and is performed by a bracket-free invisible appliance, but the common arch expansion appliance has various advantages and disadvantages. Wearing the removable appliance or the fixed appliance is a better correction auxiliary tool for a customer who does not want to select tooth extraction correction, the two ends of the arch expander are fixed on the back teeth, the situations of narrow dental arch, undersize upper dental arch and lower dental arch and the like can be improved through the expanded elastic force applying device, the wearing is convenient, the period is short, but the defects are obvious, speaking is influenced, the discomfort in the mouth is obvious, the difficulty is caused for cleaning the periodontal, the occurrence rate of gingival inflammation is high, and the rebound is easy. For the patient who wears the stealthy ware of correcting in bracket of nothing and carries out the expansion of bow, the stealthy volume of correcting in bracket of nothing is preset when correcting the ware preparation and is enlarged, and the patient wears according to the order and corrects the ware and just can play the effect of expanding the bow, nevertheless corrects the cycle and slightly longer a little relatively, and the target position that the stealthy ware of correcting in bracket of nothing is realized, and its adaptation disease scope is limited.
Disclosure of Invention
The utility model aims at providing a to do without support groove stealthy and rescue the ware and go up equipment special device, be a device that combines together with the stealthy ware of rescuring of support groove with fixed arch device that expands of molar particularly. The device is characterized in that the force application part of the device is completed by a bracket-free appliance, and the retention part is completed by combining a special device and the bracket-free appliance.
The utility model discloses an useful part lies in, can be effective and can accomplish in short time and expand the bow operation. When the bracket-free appliance applies force, the special device can play a role in retention and positioning in the force application process, thereby ensuring the high efficiency and accuracy of correction. And due to the integrated joint anchorage of the bracket-free appliance, the tooth can not be displaced unpredictably in the correction period.

Fig. 2 is a top view of the structure of this particular device.
Fig. 3 is a schematic plan view of this particular device.
Detailed Description
The utility model is used for correct earlier stage, especially correct to expanding the bow. The present invention will be described with reference to the accompanying drawings by taking the crowding of the jaw teeth as an example.
Crowding of teeth is one of the most common types of malocclusions, accounting for about 60% to 70% of malocclusions, which manifests as malposition and misalignment of teeth due to greater tooth mass than bone mass. As shown in fig. 1 and 2, the appliance is used for the mandible and is composed of an appliance body 1 and a special device 2.
The special device 2 has wire devices 213 and 214 on premolars and molars in the area of the site 3, and the special device 2 has wire devices 211 and 212 on premolars and molars in the area of the site 4, and a resin base portion 2E on the lingual tissue surface, which are integrally formed to constitute the special device 2.
The specific operation is, as shown in fig. 3:
taking a section of stainless steel wire with d =0.7mm or d =0.8mm, wherein the buccal surface of the abutment forms a bridge part 2A of a snap ring in the middle of the steel wire, and the bridge part has the length of
Width near to or far from the abutment
In a relationship of
And the bridge body is parallel to the occlusal surface,approximately positioned in the middle of the diameter of the gingiva of the abutment teeth;
secondly, the longitudinal beam 2B and the bridge body 2A are in an inverted trapezoidal structure, the included angle is 90-95 degrees, the intersection angle of the longitudinal beam 2B and the tooth long axis is about 20 degrees, and the longitudinal beam is tightly attached to the tooth surface close to the far-middle axial angle of the buccal surface to play a role in retention;
thirdly, using a pair of sharp pliers to enable the steel wires at the near and far middle ends to reach a lingual tissue surface along the near and far middle jaw abduction gap and the tongue abduction gap of the abutment to form a jaw spanning section 2C and a connecting body 2D, wherein the intersection angle of the jaw spanning section 2C and the longitudinal beam 2B is positioned at the intersection point of the abutment and the buccal side of the occlusal surface of the near and far adjacent tooth;
and fourthly, embedding the tail end of the connector 2D into a resin base 2E, wherein the thickness of the resin base 2E is 2 mm-2.5 mm, the tissue surface of the base is tightly attached to soft and hard tissues, the shape of the polished surface is similar to the shapes of the jaw arch and the tongue side, and the manufacturing is finished until the polished surface is cured.
And fifthly, buckling the special device 2 on a dental cast, and then carrying out hot forming process operation on the basis, so as to press the polymer membrane material into the bracket-free invisible appliance.
The special device is used together with the invisible appliance, the molar is pushed to increase the length of the dental arch towards the middle, the molar relation is corrected, and the arch expansion treatment in the early stage of correction is completed.
