Abstract
The invention discloses a manufacturing method of an individualized tongue-side orthodontic retainer, comprising the following steps: taking a dental model; establishing a three-dimensional CAD model;drawing an arch wire flat surface and an arch wire, and designing a single retainer CAD structure model; guiding the single retainer CAD structure model into a fast wax pattern machine to obtain a retainer wax pattern; casting the retainer wax pattern, and obtaining the retainer after necessary surface processing; guiding a two-dimensional CAD model of the arch wire into a precise marking machineto obtain a pattern with the same shape and size with the arch wire; bending to obtain the arch wire according to the pattern, and welding the arch wire and the retainer together by a laser welding method; and then placing the retainer on the dental model to carry out integral vacuum film pressing to obtain a positioning pallet. The invention can realize the individualized production according toindividual demand; in addition, the prepared retainer is matched with a tooth shape, has high precision and lasting non-deformation, is suitable for being worn for a long time by patients and has thin thickness, good anchorage stability and convenient clinical operation. The manufacturing method is widely used for the production process of the orthodontic retainer.
Description
Technical field
The present invention relates to be used for the orthodontic retainer manufacturing technology of straightening of teeth, particularly a kind of DLP digital image projective technique rapid shaping manufacture method of individuation lingual orthodontic retainer.
Background technology
For irregular tooth arrangement is neat, clinical medicine is widely used the just abnormal technology of employing.Every through the patient behind the orthodontic treatment, all need to wear orthodontic retainer with the after treatment effect, it is to rescue indispensable important component part in the process, wear orthodontic retainer and be and prevent that deformity from recurring effective measures, present stage, orthodontic retainer commonly used can be divided into removable retainer and fixed retainer.Wherein removable retainer is owing to oral cavity functions such as obstruction is chewed, pronunciations, and part patient is unwilling to wear removable retainer because feel uncomfortable and inconvenient, thereby causes the deformity recurrence.And fixed retainer can overcome the influence of patient's factor of co-operation, and keeps effect stability, reliably reaches advantages such as comfortable, thereby fixed retainer usually is subjected to the favor of most of patients.
The fixed retainer of just abnormal clinical normal employing at present can be divided into two kinds: a kind of is the universal product that standardized production has base plate and connected by steel disc, and this standardized universal product is for the tooth of Different Individual, and appropriateness is smaller.Because the configuration of surface of Different Individual tooth has nothing in common with each other, the space of keeper base plate and dental surface is filled up by bonding agent.If dental surface curvature changes greatly, the bonding agent that then needs is more, causes the keeper base plate away from tooth surface, and it is uncomfortable that the patient feels, and get loose easily, and final influence keeps effect.Another kind is the mucosity type keeper of making of twisted wire, but this type of keeper clinical manipulation is comparatively loaded down with trivial details, and the other working time of chair is long, even keeper may occur and get loose and cause shortcoming such as maintenance failure.
Summary of the invention
In order to solve above-mentioned technical problem, overcome the shortcoming and defect of above-mentioned prior art, the DLP digital image projective technique rapid shaping manufacture method that the purpose of this invention is to provide the individuation lingual orthodontic retainer, this method can not only realize the manufacturing of individuation high accuracy according to individual variation, and the orthodontic retainer of producing keeps effect stability, reliable, comfortable wearing, is fit to the patient of needs long periods of wear.
