Description
Technical field
The invention belongs to oral cavity medical assistance technique with the apparatus field and in particular to a kind of face Digital Three-Dimensional image with upper
The transfer device of jaw denture Digital Three-Dimensional imaged image coupling.
Background technology
Digital Three-Dimensional image collecting device is flourishing in oral medical field development, and the image matching method of cranium Maxillary region
Become the new opportunities of this field development.Conventional method is by the use of CT scan Three-dimension Reconstruction Model as face three
Dimension image and the images match medium of maxillary dentition 3-dimensional image, but the method is obtaining tomoscan Three-dimension Reconstruction Model mistake
The radiological dose being related in journey is big, if multiple check, is unfavorable for very much health.Also having been reported that can be by during collection facing exposure
Facial 3-dimensional image carry out mating of assisted face 3-dimensional image and denture 3-dimensional image image, but because facing color and luster is reflective,
It is difficult to be accurately identified by facial 3-dimensional image harvester, thus accuracy and the reliability finally mated can be affected.
Brought to solve the problems, such as that facing color and luster is reflective, Eneko Solaberrieta, PhD, Asier
Garmendia,PhD,Rikardo Minguez,PhD,Aritza Brizuela,PhD,andGuillermo Pradies,
PhD " Virtual Facebow Technique " discloses a kind of facebow transfer fork, and this facebow transfer fork is by a semicircle
Jaw denture pallet, intermediate connector and imaging plate are constituted, and are first coated with moulage in semicircle maxillary dentition pallet during use,
Then the maxillary dentition tray portion being coated with moulage is placed at patient's maxillary dentition, and makes imaging plate be located at patient
Outside mouthful, at this moment pass through the three-dimensional relationship that facial three-dimensional camera first records patient's denture and imaging plate, then carry out face
3-dimensional image gathers, and recycles the three-dimensional relationship of aforementioned denture and imaging plate, coupling face 3-dimensional image and maxillary dentition
3-dimensional image.Although this facebow transfer fork can be used in mating of facial 3-dimensional image and maxillary dentition 3-dimensional image image,
Positioning maxillary dentition 3-dimensional image is with respect to the position of facial 3-dimensional image, but there are following some deficiencies：1) imaging plate form
Excessively simple, for the face of identification coupling, line very little, it is unfavorable for later image coupling accuracy；2) because this facebow shifts fork
Tray portion and imaging plate be to be fixed with one it is impossible to according to the personalization of different patient's denture forms, only replace different
Pallet and use same imaging plate, lead to the waste of material and the increase of medical treatment cost；3) due to the support of this facebow transfer fork
Disc portion and imaging plate are fixed with one, and volume is larger, are unfavorable for gathering image using dentistry three-dimensional model scanner.
Content of the invention
Present invention aims to the deficiencies in the prior art, provide a kind of face Digital Three-Dimensional image and maxillary teeth
The coupling transfer device of column of figure 3-dimensional image, so that accurate recording face Digital Three-Dimensional image is digitized with maxillary dentition
The three-dimensional relationship of 3-dimensional image, increases device reusability, reduces medical treatment cost, is conducive to using existing dentistry number
Word three-dimensional model scanner gathers image, improves device practicality.
The facial Digital Three-Dimensional image that the present invention provides mates transfer device with maxillary dentition Digital Three-Dimensional image,
This device includes pallet and imaging plate, and pallet is to be made up of with the tray handle being integrally connected tray body, and tray body is
One mate with patient's maxillary dentition and semicircular in shape indent disk body, tray handle is located at the outer middle side part of semi-circular disks wall；Imaging plate
Then it is made up of 5 pieces of rectangular slabs and a connecting post, using one of rectangular slab as mesion, remaining 4 pieces with mesien level
On the basis of face, the equidirectional angle at least 15 ° is located at mesion surrounding respectively, forms ramp, lower inclined plane, left tilted surface and the right side
Inclined-plane, connecting post is located at mesien rear middle part and is connected as a single entity with it, and connecting post is had the slot being mated with tray handle, or
Imaging plate is the plate body of a undulate along the horizontal or vertical direction, and after plate body, middle part is additionally provided with the connecting post being connected as a single entity, even
Connect and the slot being mated with tray handle is had on post.
The ramp of imaging plate, lower inclined plane, left tilted surface and right tilted surface described in above transfer device and mesien angle
For 15 ° -45 °.
