Description
Technical field
This utility model relates to a kind of oral cavity prosthesis support increasing material manufacture based on metal.
Background technology
Jawbone and defected, it is the illness of a class serious harm human health in stomatology, the obstacle of the physiological functions such as it not only causes patient to chew, swallow, language, and the Face deformity that patient is serious can be caused, make patient produce serious mental maladjustment, even make some patients lose life confidence, cause individual and domestic tragedy.The reconstruction of defect upper jaw bone, is generally divided into surgery reduction and oral cavity Maxillofacial prosthesis two kinds of methods.In recent years, although various surgery taxis makes much progress, but due to the special anatomic form of Maxillary region organ and organizational structure, many defects are still difficult to adopt autologous tissue to carry out surgical repair, and the oral cavity prosthesis that most of patient adopts artificial material to make is repaired.
The manufacture of traditional oral prosthesis support mainly adopts foundry engieering, detailed process mainly contains, first patient need allow surgeon dentist observe before having an operation, and to reach the pre-object cured, and surgeon dentist meeting and surgeon together talk about concrete operation plan.The firm patient performed the operation, because the soft tissue after operation is more responsive, change also larger, therefore, oral cavity doctor can make the larger oral cavity prosthesis of a magnitude of interference to patient.Object is that such as appropriateness is chewed in order to allow patient carry out basic oral cavity function, basic sounding etc.After adapting to a period of time Deng patient, the soft tissue of patient finalizes the design almost, and after not changing, doctor goes to the final oral cavity prosthesis of patients design manufacture again.
Oral cavity prosthesis metal rack often adopts traditional foundry engieering, and lost-wax casting is one of foundry engieering usual way.Adopt standard wax to make stent model, have plurality of advantages, easy to operate, the low and high temperature melting of cost, good fluidity, can be good at standard wax to apply in foundry engieering.
But the making of wax-pattern also exists again the deficiency being difficult to avoid simultaneously.1, the thickness of standard wax is certain, is difficult to arrive individual requirement.Many patients are different to metal base portion thickness requirement, and standardized thickness is difficult to satisfied different patient to the demand of backing thickness.2, wax disk(-sc) sticker model is by the rising of wax disk(-sc) temperature, there is certain viscosity to be then pasted onto on plaster model.Skilled worker workman's mainly armrest pressing, the temperature of hands and be all the key factor to bond quality quality to the power that wax disk(-sc) applies, the impact of these anthropic factors, cannot avoid, and the proficiency level for workman requires high.3, the size of wax disk(-sc) is certain, needs workman to cut its requirement according to support.The degree of accuracy that workman cuts the edge of wax disk(-sc) edge and support will directly affect the quality of casting frame, and the support that produces even can be made defective.4, wax disk(-sc) pastes after on plaster model, needs the refine of skilled worker, the edge of refine wax pattern, is also require high to the proficiency level of skilled worker.
In order to solve the formation problems of oral cavity prosthesis support, PM technique is suggested as the another kind of processing method can extracing skeleton of partial denture.Powder metallurgy is the Technology making metal material, composite and all kinds goods using metal dust as raw material through compressing or sintering process.Its general process is: (1) makes die according to a conventional method, fills with mould, and makes plaster model; (2) Dai Mo is copied; (3) die cavity is made; (4) metal dust is filled in die cavity pressurizes, produce pressed compact and correction of the flank shape, make it have certain density and intensity; (5) be heated to above the temperature of its fusing point 2/3-3/4 in a vacuum, make firmly to combine between powder particle.But powder metallurgy Problems existing is metal forming and the contraction problem after sintering, and this must reduce the formed precision can extracing skeleton of partial denture, and manufacturing process operation is more, and cost of manufacture is even taller than casting technique.
The appearance of computer-aided design and rapid shaping technique and emulation Facial Reconstruction material, effective means is provided to these problems unsolved, especially the selective laser fusion technology that can print metal recently occurred, for digitized manufacturing system oral cavity prosthesis metal rack provides opportunity.Based on dentistry CT (CBCT) view data, patient's jaw face threedimensional model is generated through image procossing, carry out the prosthesis design of personalized oral cavity on this basis, printing rapid forming equipment by 3D again utilizes repair materials to carry out superposition manufacture, the digitized of oral cavity prosthesis treatment can be realized, this series technique will significantly improve the accuracy for the treatment of, realize painless, noinvasive, fast and rebuild the therapeutic goal of Maxillofacial defect.
Increase material manufacture, be 3 D-printing again, wherein the increasing material manufacture of metal material or the development of SLM technology and maturation, can be applied to three-dimensional printing technology in the middle of making.Because three-dimensional printing technology successively prints, thus the result of piling up layer by layer, does not affect by Workpiece structure, can go out the workpiece of labyrinth by printing and making.At present, SLM technology directly can print metal, such as titanium or titanium alloy, rustless steel etc., and applies to medical domain.So the snap ring that choice for use three-dimensional printing technology makes slender construction and complexity is a method comparatively new and feasibility is high.Further, utilize SLM technology well can not only produce oral cavity prosthesis network structure, and degree of accuracy is high, significant for making oral cavity prosthesis support.
Summary of the invention
