Abstract

The utility model provides a telescope crown denture produced by the gold deposit technology. The telescope crown denture comprises a inner crown and an outer crown, wherein the inner crown is fixed on the tooth of a patient who needs installing the denture; the outer crown is sheathed on the inner crown; a pure gold layer is covered on the inner surface of the outer crown; and the pure gold layer is obtained by deposition of pure gold electrolytic solution. The telescope crown denture has the advantages that the pure gold structure of the pure gold layer is a no-cellular dense non-cube crystal structure with higher strength; meanwhile, the errors caused by the casting technology for other precious metals do not exist, thereby improving the manufacture accuracy greatly; furthermore, under the condition that the sealing property between the inner crown and the outer crown is good, the additional adhesion effect is achieved by the mutual action of the saliva of the patient based on the adhesion principle, so as to provide the perfect retention for the denture and solve the problem of abrasion caused by relative movement between the inner crown and the outer crown of the telescope crown denture in the prior art.

Description

The telescope crown artificial tooth that the golden deposition technique of a kind of usefulness is made

Technical field

This utility model relates to the field of artificial tooth structure, particularly the manufacturing structure of telescope crown artificial tooth.

Background technology

The problem that the telescope crown artificial tooth mainly exists is to lack static friction between interior hat and the outer hat, causes relatively moving of interior hat and outer hat, and this can greatly influence therapeutic effect, raising patient's treatment cost.

The method that therefore static friction between being preced with in the multiple reinforcement and being preced with is outward arranged in the prior art.First method is the inner chamber that outer hat is dwindled in pointwise, and method is two metal dots of weldering on the inner surface of secondary crown, strengthens inside and outside hat static friction each other with this.The shortcoming of this method is, can't on purpose accurately control the size of metal coating, always needs further to revise in clinic trial telescope crown artificial tooth, thereby has improved doctor's work difficulty and treatment cost greatly.Second method is that the inner surface of being preced with outside is coated with the friction lacquer.Though this method is directly carried out when treatment, its complicated operating process mainly by means of doctor's skill and experience, is not easy to grasp.The third method is to be preced with inwall outside to add the caoutchouc elasticity cushion pad, its shortcoming is preced with inwall as thin as a wafer outside being, will embed cushion pad again is no small challenge for the processing technique of artificial tooth, and its performance depends on the free space in the outer hat and the placement location of cushion pad fully, and reliability is not good.The 4th kind of method is to be preced with inwall outside to smear synthetic resin.Same skill and the empirical shortcoming that has the dependence doctor the same of this method with smearing friction lacquer method, simultaneously, because there is situation about sticking together between the inside and outside hat in the use of synthetic resin.

In sum, though said method can improve the static friction between the inside and outside hat of telescope crown artificial tooth to some extent,, all existing process technology difficulty height, precision is difficult to grasp or is the high problem of cost.

The utility model content

In order to solve existing problem in the prior art, this utility model provides a kind of telescope crown artificial tooth of making by golden deposition technique.By smear the conductive silver lacquer on the preparation body die surface that is used to make artificial tooth, put it in the electrolyte that contains gold ion, make the gold ion in the electrolyte and the silver ion generation displacement reaction on die surface, thereby form the proof gold layer that one deck is used for being preced with outside the overlay denture inner surface on the surface of preparation body die.The thickness of proof gold layer is 0.2-0.3mm.The proof gold structure of proof gold layer is the non-cube crystal structure of the densification of pore-free, and compared to the typical natural proof gold cube crystal structure that other noble metal process technology is produced, it has higher intensity.Because the artificial tooth that provides of this utility model uses golden deposition technique manufacturing, so there is not the error that is produced in other noble metal foundry engieering in it, and the accuracy of manufacture of artificial tooth improves greatly.And then, under the good situation of inside and outside hat driving fit, just be not only tribology principle with the outer hat of artificial tooth of golden deposition technique manufacturing and the basis of the structure adhesion between the interior hat, but adhesion principles, i.e. interaction by patient's saliva produces additional adhesiving effect, outer hat inner surface and interior hat outer surface produce adhesion, thereby for artificial tooth provides perfect maintenance, have solved the generation wear problems that relatively moves between the external tooth in the prior art middle sleeve hat artificial tooth.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Introduce the specific embodiment of the present utility model below in conjunction with accompanying drawing.

As shown in Figure 1, hat 3 and outer hat 2 in the telescope crown artificial tooth that this utility model provides comprises, interior hat 3 are fixed on the tooth 4 that the patient need install artificial tooth, be preced with outward 2 be set on the hat 3.Wherein, be preced with 2 inner surface outward and have a proof gold layer of making by golden deposition technique.By smear the conductive silver lacquer on preparation body die (plaster mold) surface that is used to make artificial tooth, put it in the electrolyte of the proof gold solution that contains gold ion.Make the gold ion in the electrolyte and the silver ion generation displacement reaction on die surface, thereby form the proof gold layer 1 that one deck is used for being preced with outside the overlay denture inner surface on the surface of preparation body die.Have the brightener about 5% in the described electrolyte, make proof gold layer 1 any surface finish of final formation.The making of proof gold layer 1 needs about 6 hours time, forms the proof gold layer 1 that thickness is approximately 0.2-0.3mm afterwards, and concrete thickness depends on the clinical treatment needs.Proof gold layer 1 by golden deposition technique generation, because it forms by displacement reaction, therefore, the non-cube crystal structure of the densification that its proof gold structure is a pore-free, compared to the typical natural proof gold cube crystal structure that other noble metal process technology is produced, it has higher intensity.Because the artificial tooth that provides of this utility model uses golden deposition technique manufacturing, the displacement reaction in the golden deposition technique is by computer control, so there is not the error that is produced in other noble metal foundry engieering in it, and the accuracy of manufacture of artificial tooth improves greatly.And then, under the good situation of inside and outside hat driving fit, just be not only tribology principle with the outer hat of artificial tooth of golden deposition technique manufacturing and the basis of the structure adhesion between the interior hat, but adhesion principles, i.e. interaction by patient's saliva produces additional adhesiving effect, outer hat inner surface and interior hat outer surface produce adhesion, thereby for artificial tooth provides perfect maintenance, have solved the generation wear problems that relatively moves between the external tooth in the prior art middle sleeve hat artificial tooth.
