Embodiment
The present invention provides a kind of forming method for having reeded digitlization appliance, to make the purpose of the present invention, technologyScheme and effect are clearer, clear and definite, and the present invention is described in more detail below.It should be appreciated that described herein specificEmbodiment only to explain the present invention, is not intended to limit the present invention.
Fig. 1 is refer to, it is the reeded forming method preferred embodiment for digitizing appliance of tool of the present inventionFlow chart.As shown in figure 1, the forming method of the reeded digitlization appliance of tool, comprises the following steps：
Step S1, diaphragm is placed in film laminator preheated；Wherein, preheating temperature is 300 ~ 400 DEG C, and preheating time is 25-35s；
It is pressurized in step S2, the closing space for forming diaphragm and film laminator, is pressurized to 2.5 ~ 2.7MPa；
Step S3, tooth plaster cast is placed in film laminator and positioned at the lower section of the diaphragm；
Step S4, diaphragm pushed, until diaphragm is placed on tooth plaster cast, the digitlization appliance being molded for the first time；
Step S5, the side wall for clamping the digitlization appliance being molded for the first time for the metal pliers of L-type by one end, are obtained with recessedThe digitlization appliance of groove；Wherein, the groove of the reeded digitlization appliance of the tool caves inward.
In embodiments of the invention, in step sl by diaphragm progress preheating be in order to first be softened after, it is convenient thereafterContinuous shaping faster.In step s 4, after being pressurized in diaphragm and the closing space of film laminator formation, meeting after diaphragm is pushedShaping is gradually softened according to tooth plaster cast, helps to be molded here also with pressure difference.
Printing tooth plaster cast is successively accumulated by DLP-3D printing instruments in step s3；Wherein, each layer of printingPiling height is 0.05mm.The liquid bath of resin can be accommodated comprising one in DLP-3D printing instruments, can be by certain wave for holdingThe resin of long ultraviolet light solidify afterwards（Such as polymethyl methacrylate）, DLP imaging systems are placed in below liquid bath, and it is imagedFace is placed exactly in liquid bath bottom, by energy and Graph Control, each curable certain thickness（Such as 0.05mm）And shape is thinLayer resin（This layer of resin is identical with the cross-sectional shape obtained by above cutting）.One shift mechanism is set above liquid bath, oftenCertain altitude is lifted upwards after the completion of secondary section exposure（This is highly consistent with lift height）So that the solid-state of current curing completionResin is separated with liquid bath bottom surface and is bonded on the resin bed that lifting plate or last time are molded, so by successively exposing and being liftedTo generate 3D solid.
It is preferred that, as shown in Fig. 2 the metal pliers specifically include the first tong arm 100 and be hinged with the first tong arm secondTong arm 200；First tong arm 100 includes L-type binding clip 110, the first articulated section 120 and the first handle 130 set gradually；InstituteState linear pattern binding clip 210, the second articulated section 220 and second handle 230 that the second tong arm 200 includes setting gradually；Described firstThe articulated section 220 of articulated section 120 and second is by being hinged fixation.
It is preferred that, the step S5 is specifically included：
Step S51, the outer wall side that L-type binding clip is placed in the digitlization appliance being molded for the first time, and linear pattern binding clip is placed in justThe inwall side of the digitlization appliance of secondary shaping；
Step S52, first handle and/or second handle are exerted a force so that L-type binding clip and linear pattern binding clip clamp what is be molded for the first timeThe side wall of appliance is digitized, obtains having reeded digitlization appliance.
As shown in figure 3, after the digitlization appliance 10 being molded for the first time is clamped through L-type binding clip and linear pattern binding clip, formed toInterior groove 20.So tooth needs the patient corrected to have after reeded digitize on appliance band, each in applianceTooth is under the active force of appliance to be that the point of rotation is gradually moved to position to be corrected at all.If not in digitlization applianceSide wall on set groove 20, then may make root of the tooth this tooth rotate during outwards bucktooth go out, so take applianceOrthodontic is not only gone back into original position afterwards, also make it that also bucktooth goes out root of the tooth.And in the present invention, in the digitlization appliance being molded for the first timeSide wall, by one end for L-type metal pliers clamp after forms groove 20, the groove 20 tooth with all for the point of rotation it is insideDuring rotation, due to many restriction effects of groove, it can ensure that and be not subjected to displacement at all during the rotation, it is ensured that rescuedAccuracy of the device to orthodontic.
It is preferred that, L-type binding clip and linear pattern binding clip clamp the side for the digitlization appliance being molded for the first time in the step S52The duration of wall is 5-10s.
The forming method of the reeded digitlization appliance of tool, wherein, the depth of groove described in the step S5For 0.5-5mm.
It is preferred that, preheating temperature is 350 DEG C in the step S1, and preheating time is 30s；Closing space in the step S2In be pressurized to 2.6MPa；The pressing time for pushing diaphragm in the step S4 is 30-60s；Optimal, will in the step S4The pressing time that diaphragm is pushed is 45s.
In summary, the forming method of the reeded digitlization appliance of tool provided by the present invention, method includes：By filmPiece is placed in film laminator and preheated；Wherein, preheating temperature is 300 ~ 400 DEG C, and preheating time is 25-35s；By diaphragm and press moldIt is pressurized in the closing space of machine formation, is pressurized to 2.5 ~ 2.7MPa；Tooth plaster cast is placed in film laminator and is located atThe lower section of the diaphragm；Diaphragm is pushed, until diaphragm is placed on tooth plaster cast, the digitlization being molded for the first time is rescuedDevice；The side wall for the digitlization appliance being molded for the first time is clamped for the metal pliers of L-type by one end, obtains having reeded numeralChange appliance；Wherein, the groove of the reeded digitlization appliance of the tool caves inward.The present invention is L-type using one endMetal pliers clamp be molded for the first time digitlization appliance side wall so that groove is precisely molded, and the tool formed is reededAppliance is digitized to the control effect of root of the tooth more preferably.
It should be appreciated that the application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, canTo be improved or converted according to the above description, all these modifications and variations should all belong to the guarantor of appended claims of the present inventionProtect scope.
