technical field

The utility model relates to the technical field of orthodontics, in particular to a production system of an alveolar bone shaping device and the alveolar bone shaping device.

Background technique

Children's dental arch development goes through three stages: deciduous dentition, mixed dentition and permanent dentition. The width, depth and circumference of the dental arch undergo changes from deciduous dentition to permanent dentition to adapt to the eruption and arrangement of permanent teeth, and finally Forms neat upper and lower dentition. Due to the abnormal (insufficient) development of the dental arch due to genetic and environmental factors, the eruption space of the permanent teeth is not enough, and clinically leads to occlusal developmental deformities such as dentition crowding, deep overbite, overbite, and anterior/posterior crossbite. The most common abnormalities in dental arch development are insufficient width between canines, bicuspids, and permanent molars, resulting in reduced arch circumference and dental crowding. Expansion is the first choice clinically to solve underdevelopment of the dental arch. Generally, removable appliances are the mainstay. The timing of treatment is for children aged 7-9. The purpose is to expand the maxillary palatine suture and achieve the effect of bony arch expansion.

S5. Generate a correction model based on the current model according to the correction amount and growth amount of each tooth.

Since the utility model is aimed at children, the growth and development of children's dental arches and teeth need to be considered. Therefore, in addition to the amount of correction, the growth amount is also reserved for each tooth, that is, when designing the shaper, it is reserved for Space for teeth to grow. In this way, an induction groove is provided for the eruption of the permanent teeth, which can effectively induce the normal growth of the permanent teeth while correcting the shape of the dental arch, and further improve the effect of the orthodontic treatment.

S6, making a shaper according to the correction model.

Further, generate a correction model, including the following sub-steps:

S51, according to the personal information of the user, determine the single correction amount n _i of the i-th tooth;

S52, calculating the correction times P _i of the i-th tooth, said P _i =N _i /n _i ;

S53, based on the current model, generate a plurality of orthodontic models, the latter orthodontic model is based on the previous orthodontic model, and the sheath position of the i-th tooth is changed S _i until the sheath of the i-th tooth reaches the standard model position.

Further, generating the correction model also includes the following sub-steps:

S54. Obtain the total number Q of corrected models, where Q is the maximum value of the corrected times Pi;

S55, calculating the single growth amount m _i of the i-th tooth, where m _i =M _i /Q;

S56, the plurality of correction models, the latter correction model is based on the previous correction model, and the sheath position of the i-th tooth is changed by m _i .

In the above sub-steps S51-S56, the single correction amount refers to the correction range for the teeth each time. Due to the limited capacity of people, each correction can only correct a small amount, that is, the single correction quantity. It should be further explained that the single correction amount is not limited to the position of the teeth, but combines the parameters of the joint correction position of the dental arch and the teeth, that is, on the basis of the correction range of the dental arch, the specific correction value of each tooth is fitted. The value obtained. The single growth amount is calculated on the basis of the single correction amount, the number of corrections, and the growth value of the child's permanent teeth calculated in conjunction with the replacement time of the shaper. To sum up, on the basis of the former orthodontic model, the latter orthodontic model first needs to make shape adjustments according to the single correction amount, and then increase the size of the eruption induction groove of permanent teeth according to the single growth amount to achieve Steady successive induction of growth effects.

Optionally, the value range of the single correction amount S _i is 0.1 mm to 0.5 mm.

Preferably, the value range of the single correction amount S _i is 0.2 mm to 0.3 mm.
