Abstract
The utility model discloses a tool for assisting to make a denture. The tool is characterized by comprising a lower base plate and an upper base plate which are capable of locking mutually, a groove for holding a dental impression is placed on the lower base plate, simultaneously, three or more guiding posts are arranged on the periphery of the groove, a plurality of positioning portions are in sunk arrangement on the lower surface of the upper base plate according to arrangement of teeth in the mouth, three or more positioning holes corresponding to the guiding posts are arranged on the peripheries of the positioning portions of the upper base plate, and three or more register marks for three-dimensional laser scanning are disposed on the periphery of the upper base plate. By employing the tool combined with the three-dimensional laser scanning technology, a dentist or a dental technician can design and trim shapes and sizes of a denture on a computer auxiliary design software after obtaining three-dimensional information of teeth, thereby shortening denture making time and improving denture making quality.
Description
Technical field
This utility model is about a kind of instrument, more particularly, and about a kind of instrument that is used to assist to make artificial tooth.
Background technology
At present dental field, odontologist is when the reparation of carrying out tooth, finishing or treatment, and is not only quite complicated, but also very time-consuming.Its concrete process is: the concrete shape of the tooth that odontologist repairs is as required produced dental impressions, produces Gypsum Fibrosum tooth mould by the dentistry skilled worker according to dental impressions again.On the basis of Gypsum Fibrosum tooth mould, dentistry skilled worker need prepare the wax-pattern and the transition piece of interior hat of tooth or bridge, uses to make artificial tooth.Because this process is all finished by hand by the dentistry skilled worker, so difference of making by hand of not unifying and technical merit, make the quality of artificial tooth uneven, and in para-position, cause a deviation inevitably, thereby cause frequent and time-consuming later stage finishing, even often defective work occurs and need make artificial tooth again, can cooperate the shape of patients teeth to guarantee artificial tooth.
The utility model content
The purpose of this utility model provides a kind of instrument that is used to assist to make artificial tooth that can avoid too much using manual work, and backward three-dimensional laser retaining is retouched measure and machining convenient.
The instrument that is used in this utility model assist to make artificial tooth is made up of upper and lower two infrabasal plates that can fasten mutually, upper substrates, on described infrabasal plate, be provided with a groove that is used to place dental impressions, simultaneously be provided with lead more than three or three at the periphery of described groove; The lower surface of described upper substrate down convexes with a plurality of location divisions that distribute and arrange according to the oral cavity inner teeth gear, be provided with the locating hole corresponding with described lead more than three or three at all location division peripheries of described upper substrate, the periphery at described upper substrate also is provided with the alignment mark of establishing for 3 D laser scanning more than three or three simultaneously.
Described location division is L-shaped.
Described upper substrate and infrabasal plate are made by the material of high-dimensional stability.
Described lead, locating hole and alignment mark are three, and distribution all triangular in shape.
The lower surface of described upper substrate is convexly equipped with 14 location divisions.
Described groove is an open-work.
Utilize the instrument in this utility model to cooperate the 3 D laser scanning measuring technique after obtaining the three-dimensional data of tooth, odontologist or dentistry skilled worker can shape, the size to artificial tooth design and repair on CAD software, thereby shorten artificial tooth Production Time and improve the artificial tooth fabricating quality.

The specific embodiment
The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 4, the mould that is used to make artificial tooth in this utility model is made up of upper and lower two upper substrates that can fasten mutually 1, infrabasal plate 2, be provided with a groove 10 that is used to place dental impressions 3 on infrabasal plate 2, wherein dental impressions 3 is used to inject the dental plaster raw material to make Gypsum Fibrosum tooth mould.Simultaneously be provided with lead 11 more than three or three at the periphery of groove 10, this utility model is an example with three leads 11, but is not limited to this, and wherein three leads 11 are equilateral triangle and distribute.
As shown in Figures 2 and 3, upper substrate 1 down convexes with a plurality of location divisions 20 at the lower surface corresponding with infrabasal plate 2 fastenings, and this utility model is an example with 14 location divisions 20, as shown in Figure 3, but is not limited to this.Each location division 20 is L-shaped, and each location division 20 is to arrange according to the distributing position of oral cavity inner teeth gear in the position distribution of upper substrate 1 lower surface, be provided with more than three or three the locating hole 21 corresponding with lead 11 on the infrabasal plate 2 at the location division of upper substrate 1 20 peripheries, promptly lead 11 can fasten with locating hole 21.The position opposite triangular in shape with locating hole 21,20 peripheries are provided with three alignment marks 22 in the location division of upper substrate 1, lead 11, locating hole 21 and alignment mark 22 are all triangular in shape, and the para-position process is faster and accurate when making three-dimensional computer scanner uni CAD (computer aided design).Upper and lower base plate 1,2 in this utility model is made by the material of high-dimensional stability.
As shown in Figure 3, location division 20 is fixed on the lower surface of upper substrate 2 according to the mode that the human teeth arranges, and this location division 20 can be integrally formed with upper substrate 1, also can be fixed by the connector (not shown).
As shown in Figure 5, be located at the groove 10 on the infrabasal plate 2, also can by be directly arranged on the infrabasal plate 2 open-work with substitute, be printed on dental impressions 3 and just embed as long as can make.
The concrete use of mould that is used to make artificial tooth in this utility model is as follows:
1, at first makes patient's Buccodental die 3.
2, then dental impressions 3 is inserted in the infrabasal plate 2 intermediary grooves 10, in dental impressions 3, inject gypsum raw material to make Gypsum Fibrosum tooth mould, during Gypsum Fibrosum tooth contour forming, utilize lead 11 and locating hole 21 that upper and lower base plate 1,2 is fastened, make each tooth napex form L shaped location shrinkage pool, for each tooth provides accurate position and direction data, the para-position process in the three-dimensional computer scanner uni CAD (computer aided design) is more fast reached accurately.
3, in instrument, take out the Gypsum Fibrosum tooth mould that is shaped, after utilizing location shrinkage pool on the Gypsum Fibrosum tooth mould to cooperate the 3 D laser scanning measuring technique to obtain the three-dimensional data of tooth, odontologist or dentistry skilled worker can shape and the size to artificial tooth design and repair on computer aided design software, thereby shorten artificial tooth Production Time and improve the artificial tooth fabricating quality.
