Embodiments provide the manufacture method of another kind of orthodontic bracket, as in figure 2 it is shown, described method includes:
201, the initial three-dimensional dental arch model before orthodontic treatment is obtained.
For the embodiment of the present invention, described step 201 specifically includes: comprise the three-dimensional digital information of root of the tooth, corona, alveolar bone, skull before obtaining orthodontic treatment；According to described three-dimensional digital information, generate initial three-dimensional dental arch model.
Specifically, it is possible to obtain the oral cavity three-dimensional digital model before orthodontic treatment by medical image acquisition device, including the tooth data utilizing Cranial Computed Tomography scanning to obtain and skull, alveolar bone data；Utilize the corona information data that mouth interscan instrument (or plaster model scanner) obtains.The initial three-dimensional dental arch model comprising corona, root of the tooth, alveolar bone, skull data is built by Medical Image Processing software (or other third party softwares).In this threedimensional model, each tooth (containing corona and root of the tooth) should be the independence " part " that can individually move.
202, according to presetting normal population cephalometry value scope and default index point, initial three-dimensional dental arch model is digitized virtual orthodontic row's tooth, builds the threedimensional model obtaining normal dentition state.
For the embodiment of the present invention, described step 202 specifically includes: according to default index point, described initial three-dimensional dental arch model is carried out three-dimensional measurement, and building upper lower jaw arch so that the measured value obtained through three-dimensional measurement is within the scope of default normal population cephalometry value；According to described upper lower jaw arch, described initial three-dimensional dental arch model is digitized virtual orthodontic row's tooth, builds the threedimensional model obtaining normal dentition state.
Specifically, initial three-dimensional dental arch model configures index point, carries out three-dimensional measurement.The selection of index point and measure the item are all according to correction subject the recognized standard, for instance, the width of alveolar basal bone and length, upper and lower central incisor gradient and bulging, angle of mandible etc..Lower jaw arch on structure so that initial three-dimensional dental arch model is according to after the upper lower jaw arch marshalling built, and above-mentioned measure the item value is within the scope of default normal population cephalometry value.According to the upper lower jaw arch built, initial three-dimensional dental arch model is digitized virtual orthodontic row's tooth, sets up neutral molar relation, normal occluding relation and normal laminating covering, thus building the threedimensional model obtaining normal dentition state.
203, according to the lip buccal side corona form in threedimensional model, smooth upper lower jaw arch wire is built.
Specifically, extract the corona buccal labial surface shape information of central incisor, left and right canine tooth, left and right first molar in the threedimensional model of normal dentition state, utilize quadravalence Function Fitting to go out a smoothed curve being positioned at clinical crown height midpoint.Then by above-mentioned smoothed curve along corona buccal labial surface normal direction outward expansion 2mm.Then with this smoothed curve for inboard boundary, build the square arch wire that a sliver transvers section is 0.020 (tooth is axial) X0.025 (corona buccal labial surface normal direction) inch, and then construct smooth upper lower jaw arch wire.
204, the form positioning brackets parent according to the tooth position information in threedimensional model and upper lower jaw arch wire.
Wherein, described bracket parent is without bracket base and unstructured groove.
Specifically, the STL model of standard bracket parent is imported.This bracket model without bracket base, unstructured groove, without parameters such as axial rake set in advance, inclination angle, torques, but comprise the bracket wing and hook.In the threedimensional model of normal dentition state according to tooth position information and on the form positioning brackets parent of lower jaw arch wire.Bracket parent can slide along arch wire, it is also possible to arch wire is that axle rotates, until the bracket parent volume highlighted outside corona buccal labial surface minimum (namely supporter groove is the shortest with the junction of bracket base).
205, deduct from bracket parent through arch wire part, build obtain the supporter groove with groove.
Specifically, utilize Boolean calculation, deduct from bracket parent through arch wire part, obtain the supporter groove with groove.Two sharp right of groove upper surface are done chamfered, thus obtaining the personalized bracket body that can carry out producing.
206, centered by the rectangle that bracket parent intersects with corona buccal labial surface, respectively along normal orientation outward expansion first pre-set dimension on four limits, the plane pattern that bracket base is corresponding is constructed.
Wherein, described first pre-set dimension can configure according to the actual requirements, and for the embodiment of the present invention, the first pre-set dimension is configurable to 0.5mm.
207, by plane pattern along outside uniform expansion the second pre-set dimension of corona buccal labial surface normal orientation, build and obtain bracket base.
Wherein, described second pre-set dimension can configure according to the actual requirements, and for the embodiment of the present invention, the second pre-set dimension is configurable to 0.2mm.
Specifically, intersect centered by rectangle by bracket parent with corona buccal labial surface, respectively along the normal orientation outward expansion 0.5mm on four limits, construct the plane pattern of bracket base.By this plane pattern along the outside uniform expansion 0.2mm of buccal labial surface normal orientation, obtain personalized bracket base plate thus building.
208, supporter groove and bracket base are merged obtain orthodontic bracket.
Specifically, utilize Boolean calculation, personalized bracket body is merged with personalized bracket base plate and obtains complete personalized orthodontic bracket.
