Description
Technical field
The present invention relates to a kind of 3-D scanning structures, and in particular to one kind is for improving 3-D scanning precision in polydonita position mouthful
Auxiliary device and application method.
Background technique
Spatial digitizer is one of the milestone of oral cavity Digital Medicine Technology in mouthful, has overturned producing for conventional dental stamp
Mode, it is no longer necessary to the stamp and plaster cast of entity, and the 3 D graphic data of a mouthful inner teeth gear, gum can be directly acquired,
For all kinds of oral cavity digitadiagnosis and design.However, due to the limitation in scanning motion space in mouth, current optical principle
Spatial digitizer scanning form is smaller in mouthful, when it is higher to scan single tooth precision, but scanning polydonita position, since multiple haplopia windows scan
The continuous splicing of data is easy to cause biggish accumulative stitching error.
Summary of the invention
The object of the present invention is to provide a kind of for improving the auxiliary device of 3-D scanning precision in polydonita position mouthful, the device
When can be used for the joint reparation of polydonita position, the exact space position relationship of polydonita position is directly acquired with 3-D scanning in mouth, reduces mouth
Multi-view data stitching error when interior three-dimensional polydonita position.
In order to achieve the above object, the present invention has following technical solution:
Of the invention is a kind of for improving the auxiliary device of 3-D scanning precision in polydonita position mouthful, comprising:
Shape is the semicolumn of diameter 3-10mm, the material of the semicolumn be can room temperature moulding soft material；It is described
Semicolumn is can be directly realized by polydonita position mouthful for bonding or bundled fixed in abutment or dental implant scan shaft
3-D scanning；
On the semicolumn, it is equipped with several convex-concave profile structures, in 12cm length, each individual convex concave
The three-dimensional profile of shape structure all has uniqueness；
On the semicolumn top, middle part, lower part, three holes are respectively equipped with, are for covering or being adhered to tooth kind
In implant scan shaft or dental preparations.
Wherein, the cross-sectional shape of the semicolumn is semicircle, several described convex-concave profile structures are 0-9, a-z
Three-dimensional symbol shape, for being conducive to the splicing of more form scan datas on the surface of semicolumn.
Wherein, several described convex-concave profile structures are uniformly distributed in semi-cylinder surface, several convex-concave profile structures
Height be 0.5-1mm；It is described can the soft material of room temperature moulding include tin welding wire, copper wire, aluminium wire with plastic foreskin or
Elastic force rubber band.
Wherein, the planar section of semicolumn can be reduced the interference formed with gum towards gum；Half circular surfaces of semicolumn
It is partially toward to jaw tooth, scanning when scans semicircle surface portion, can increase feature area when multi-angle scanning.
The present invention has the advantages that being directly acquired when the device can be used for the joint reparation of polydonita position with 3-D scanning in mouth
The exact space position relationship of polydonita position reduces multi-view data stitching error when three-dimensional polydonita position in mouth.
Detailed description of the invention
Fig. 1 is the schematic diagram of structure of the invention.
Fig. 2 be Fig. 1 schematic diagram from A-A to cross section.
In figure, 1, hole；2, several convex-concave profile structures；3, planar section；4, semicircle surface portion.
Specific embodiment
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
Referring to Fig. 1,2, of the invention is a kind of for improving the auxiliary device of 3-D scanning precision in polydonita position mouthful, comprising:
Shape is the semicolumn of diameter 3-10mm, the material of the semicolumn be can room temperature moulding soft material；It is described
Semicolumn is can be directly realized by polydonita position mouthful for bonding or bundled fixed in abutment or dental implant scan shaft
3-D scanning；
On the semicolumn, it is equipped with several convex-concave profile structures, in 12cm length, each individual convex concave
The three-dimensional profile of shape structure all has uniqueness；
On the semicolumn top, middle part, lower part, three holes are respectively equipped with, are for covering or being adhered to tooth kind
In implant scan shaft or dental preparations.
The cross-sectional shape of the semicolumn is semicircle, several described convex-concave profile structures are the solid of 0-9, a-z
Symbol shape, for being conducive to the splicing of more form scan datas on the surface of semicolumn.
