Description
Technical field
The present invention relates to artificial tooth preparation field, in particular to a kind of complete denture one based on DLP photocuring 3D printing
Change preparation method.
Background technique
Traditional dentures repai requires after tooth extraction wound healing and the alveolar ridge absorption trend stabilization sub stage can just carry out, usually
Patient need to wait about 3 months after extraction, and prolonged dentition defect swallows function to the psychological condition, face and chewing of patient
Energy, pronunciation etc. have an immense impact on.Patient forwardly wants to restore denture as early as possible, as far as possible the shortening agomphosis time.Cause
This, needs to wear to patient as early as possible after extraction and complete denture at once or half mouthful of artificial tooth is used to allow patient to exempt to cater to the demand of patient
Except the extraction phase, restore the physiological function sexual stimulus of patient edentulous region in time, while meeting the beauty and psychological needs of patient, subtracts
It is few to give patient's bring various damages because of dentition defect, increase the confidence of patient, compressing tooth extraction wound can also be played, reduced out
The purpose of blood.
At once full mouth or half mouthful of artificial tooth produce record cast before tooth is pulled out, and record Centric relation position and interarch distance, make
Reference when to determine jaw relationship later and arrange tooth.The functional impression at remaining tooth and anodontia usually is obtained with individual tray,
Stone model is perfused, jaw relationship is recorded according to the natural teeth remained in mouth.Heel row tooth is tried in restocking on, completes full mouth or half
Mouth artificial tooth immerses spare in thimerosal.After pulling out remaining tooth, finishing alveolar bone, wear immediately into immediate denture, and tune mill.
Traditional complete denture at once or half mouthful of artificial tooth production mostly clog work using heat setting using polymethyl methacrylate
Skill production, manufacturing process need by mounted box, filling, pressurization, water-bath polymerization and etc., manufacturing process is cumbersome, time-consuming and laborious.And
And complete denture or half mouthful of artificial tooth be in the manufacturing process of traditional heat setting filling technique, usually due to the deformation of base wax pattern, poly- first
Base methacrylate powder liquid proportional is not easy accurately to control, and flask is placed on squeezer in uneven, heat treatment process of pressurizeing and heats up
Speed and the retention time be not easy accurate perception and control etc. factors influence, there is slight crack so as to cause plaster cast, or
The defects of basal seat area after completing deforms or there are bubbles.And it can be generated after the polymerization of thermohardening type denture base resin
A degree of contraction will make basal seat area tissue surface and the adaptability in mucous membrane of mouth face poor if contraction is excessive, influence solid
Position.In addition row's tooth of traditional complete denture or half mouthful of artificial tooth is completed by skilled worker, and consuming time is long, and arranges the quality and skill of tooth
The technical level of work is closely related, is easy to appear the deviation of quality.And immediate denture is different from conventional dentures repai, needs one
Secondary property pulls out more teeth, therefore the cast trimming before extraction is difficult accurately to will have a direct impact on the steady and maintenance of dummy,
It causes patient assessment often, is related to repeatedly repairing.
It can constantly be absorbed additionally, due to alveolar bone in 3 months after extraction is unstable, therefore full mouth or half mouthful at once
Artificial tooth is worn with easily occurring the symptoms such as loosen, not closely sealed, maintenance is poor after a period of time, needs to remake provisional full mouth or half mouthful
Artificial tooth, and remake needs and take an undesirably long time, it makes troubles to patient.
In order to shorten fabrication cycle, cost of manufacture and improve quality, occur making artificial tooth using 3D printer in the market；
Due to 3D printer printing artificial tooth have the advantages that the period is short, at low cost and quality is relatively good, thus accelerate 3D printer in
The application of dental industry.
But during 3D printer manufactures complete denture, base and artificial tooth are individually printed by 3D printer
Come, then again by base together with artificial tooth cementation, to complete the manufacture of complete denture；Base and justice just due to printing
Tooth also needs cementation together, therefore the integration system that cannot achieve base and artificial tooth is standby；Simultaneously as base also needs to glue with artificial tooth
Gu together, thus the two bond strength and the poor quality after combining, and manufacturing process is relative complex；Furthermore in printing base
And during artificial tooth, print platform is larger from the peeling force in hopper, then due to density unevenness everywhere in the solution in hopper, from
And cause the density CONSENSUS of base and artificial tooth everywhere poor, thus influence the intensity of complete denture.
Therefore, it is badly in need of wanting a kind of and realizes that complete denture integration system is standby and peeling force is small and base and artificial tooth density everywhere
Consistency is good to overcome above-mentioned defect based on the complete denture integral preparation method of DLP photocuring 3D printing.
Summary of the invention
In order to overcome the disadvantages mentioned above and deficiency of the prior art, it is solid based on DLP light that the purpose of the present invention is to provide one kind
It is standby to be able to achieve complete denture integration system for the complete denture integral preparation method for changing 3D printing, and has peeling force small and base
Support and the good advantage of the density CONSENSUS of artificial tooth everywhere.
