Description
Technical Field
The utility model belongs to tooth and jaw just abnormal apparatus field, concretely relates to customization formula correction system that can arrange the tooth fast.
Background
The irregular arrangement of teeth is one of the important contents of orthodontic treatment. Orthodontists and children dentists typically align crowded teeth using slow arch expansion devices, 2X4 orthodontic procedures, and the like during the mixed dentition period and the initial period of the permanent dentition. These devices and means, although effective, have problems of long time, high cost, frequent re-diagnosis, etc. In recent years, some preformed orthodontic appliances have appeared, which substantially separate upper and lower teeth by using preformed silicone pads, so that the upper and lower teeth cannot be engaged together in the wearing process of the orthodontic appliances, thereby reducing the locking relationship between the upper and lower teeth, and extruding the teeth by using soft lip blocks and tongue blocks on the upper and lower sides of the pads to produce the effect of aligning the teeth. There are already a number of patents related to personal and organizational applications worldwide, such as chinese patent application CN201621165508.8, chinese patent application CN201810200931.4, chinese patent application CN201320803403.0, us patent application USD 717449S, german patent application DE 102005005503B 3, etc.
The Chinese patent application CN201621165508.8 discloses a personalized preformed dental appliance, wherein a framework body made of a thermal memory material is arranged on a bracket body, so that the appliance has a personalized adjusting function. The invention is intended to give a patient a muscle function trainer with standard size, then realizes the individuation of the appliance through a processing mode of heating and softening the framework body firstly, adjusting according to the tooth model and then cooling and shaping, and overcomes the defect that only large, medium and small sizes are selected before.
However, there are two major types of disadvantages associated with current preformed dental appliances:
the common disadvantages are: the doctor is difficult to monitor due to the multiple times of the return visits; the force applied to the teeth is difficult to estimate and some teeth may be stressed too much causing side effects. The accelerated movement of the teeth cannot be promoted with a suitable vibration device.
The unique disadvantages are as follows: non-customized appliances (e.g., USD 717449S) do not guarantee that each tooth will receive the corrective force with equal force magnitude. The appliance (such as CN 201621165508.8) which can be personalized by simple adjustment has a simple process of adjusting temperature rise and fall, and does not have a function of adjusting each tooth individually, and the degree of personalization is too coarse.
In conclusion, each patient has different and complicated malocclusion conditions, and the existing preformed dental appliance has a plurality of defects, so that the using effect is difficult to achieve.

In addition, the pressure point "corresponds to" the receding area, which means that the pressure action direction of the pressure point is consistent with the material reduction direction of the receding area, so that when the pressure point acts on the teeth to move the teeth to the normal position, there is a space for the teeth to move, i.e. the receding area. Thus, the teeth can be smoothly straightened to the normal positions.

In addition, in the above examples one to ten, in order to precisely design the amount of pressure applied to the deformed tooth, the calculation can be performed according to the elastic modulus of the material used for the appliance, so as to obtain the specific size of the deformed tooth, which needs to be thickened or retracted.
Materials commonly used for existing appliances are exemplified by: material 1: polymeric plastics may be used.
Such as PETG, as shown in fig. 6, 8, 10, 12. The name of Chinese: polyethylene terephthalate-1, 4-cyclohexanedimethanol ester. The name of English: poly (ethylene terephthalate-1, 4-cylcohexylenedimethylene terephthalate). The material is a transparent sheet, shaped by hot pressing on a 3D printed dental model. The thickness of the material sheet is generally between 0.75mm and 3mm, and the material sheet can be a soft film sheet or a hard film sheet. When a force of 50g is applied, the material needs to be deformed by about 0.25 mm. When a force of 25g is applied, the material needs to be deformed by about 0.15 mm.
Material 2: a silicone material may be used as shown in fig. 7, 9, 11, 13. Such as high temperature vulcanizable silica gel (HTV), room temperature vulcanizable silica gel (RTV). When 50g of force is applied, it is necessary to deform a silica gel having a thickness of 2 to 3mm by about 0.4 mm. When a force of 25g is applied, it is necessary to deform a silica gel having a thickness of 2 to 3mm by about 0.3 mm.
In addition, it should be further noted that the thickness dimension of the thickened material of the pressure part can be the same as the thickness dimension of the reduced material of the buffer part. However, since there is a physiological periodontal ligament space between the tooth and the alveolar bone supporting tissue itself (the periodontal ligament space on one side is about 0.18-0.25mm, doubled bilaterally), the distance of movement of the tooth after a force is applied may be greater than the actual amount of material thickening. As another embodiment of this embodiment, the thickness of the reduced material of the buffer portion may be designed to be slightly greater than the thickness of the thickened material of the pressure portion, so as to achieve a better correction effect.
In addition, a process flow for manufacturing the orthodontic system of the embodiment is also provided:
in the first step, a model of a tooth is obtained by directly optically scanning the patient's tooth, performing three-dimensional modeling on the patient's tooth, or preparing a negative tooth mold from a material (including but not limited to impression materials such as alginate, silicone rubber, polyether, and the like) and casting the positive tooth mold with plaster or similar materials.
And secondly, based on the tooth model of the individual, under the guidance of biomechanical analysis, the tooth correction system with the characteristics is designed in a personalized mode. The design process is characterized as follows: and the thickness and the shape of the pad, the upper lip block, the lower lip block, the upper tongue block and the lower tongue block are designed individually by analyzing the irregular degree of the arrangement of each tooth. For the teeth outside the dental arch, the outer side of the ectopic direction of the teeth is thickened with a gear or a tongue gear to ensure that the teeth move towards the direction in which the teeth are arranged; meanwhile, the thick stop or the tongue stop is properly buffered at the inner side of the ectopic direction, so that the teeth are not hindered by the appliance when moving to the orderly arrangement direction. For teeth needing to apply torque force, the thick stop or the tongue stop is thickened and buffered in a proper position on one side of the crown and the thick stop or the tongue stop is thickened and buffered in a proper position on the opposite side of the crown through biomechanical analysis so as to apply paired torque force to the teeth. For the teeth needing to be elongated, the thick gear and the tongue gear on the root of the crown are thickened simultaneously through biomechanical analysis, and the cushion is properly buffered. For the teeth needing to be pressed down, the thick and tongue shelves of the combined pad and the incisal end of the teeth are properly heightened through biomechanical analysis so as to press down the teeth. For the teeth needing to be moved integrally, the thick gear or the tongue gear is thickened at a proper position and buffered at a proper position through biomechanical analysis so as to realize the integral movement of the teeth. For the teeth needing oblique movement, the thick shelves or the tongue shelves are thickened at proper positions and buffered at proper positions through biomechanical analysis so as to realize the oblique movement of the teeth.
Finally, the appliance is made of silica gel material or medical polymer material based on personalized design so as to ensure that the appliance has enough elasticity.
The customized orthodontic system of the embodiment can be oriented to individually customize teeth of a specific patient, and can realize quick and accurate correction.
