Description
Technical field
The present invention relates to a kind of designing and manufacturing methods of dental implant, and in particular to a kind of dental implant automation is virtual
Method for implantation.
Background technique
Tooth-implanting refer to it is a kind of based on the substructure being implanted into bone tissue support, maintenance top dental case
Agomphosis repair mode.Planting body (general similar to root form), underwent operative is made using artificial material (such as metal, ceramics etc.) in it
(lower jaw is usually gone up) in method implanting tissue and obtains the firm maintenance of bone tissue and is supported, is connected by special device and mode
Connect the dental case for supporting top.Tooth-implanting can obtain and natural teeth function, structure and aesthetic effect are quite similar repairs
Multiple effect, has become the preferred repair mode of more and more agomphosis patients.But in the prior art, the main experience using people come
Realize completing for planting body；It is difficult to accomplish high efficiency, safety and accuracy, can not accomplishes to improve Dental implantion reparation
Success rate.
Summary of the invention
The object of the present invention is to provide a kind of automations of dental implant to be virtually implanted method, is able to achieve the accurate of dental implant
It is virtually implanted, in conjunction with automatic measurement algorithm software, the full-automatic digitized mine of virtual Dental implantion can be further realized, had
Help improve efficiency, safety and the accuracy of Dental implant surgery guide device, and improves the success rate of Dental implantion reparation in turn.
In order to achieve the above object, the present invention has following technical scheme:
A kind of dental implant automation of the invention is virtually implanted method, there is following steps:
1) edentulous region alveolar ridge mucous membrane, adjacent teeth are obtained, to jaw tooth surface and occlusion three-dimensional data with spatial digitizer in mouth；
Edentulous region alveolar bone and adjacent teeth three-dimensional data are obtained with CT；
2) in CAD software, using remaining tooth as common region, with common region registration Algorithm, by two kinds of data fusions,
And the denture of CT scan is replaced with the denture in 3 d scan data in mouth；
3) alveolar ridge edentulous area is virtually filled and led up in CAD software；
4) it when single tooth is virtually planted, measures and defines the plant of the middle-distant direction of edentulous region, cheek-tongue direction midpoint as planting body
Angle of striking；It when polydonita is virtually planted, selects the central den of tooth to be repaired to plant site, while guaranteeing that distance is neighbouring natural
Root of the tooth 2mm；
5) in CAD software, the vertical direction of bite plane is measured as implantation direction, polydonita will also guarantee more when planting
It is parallel to each other between a planting body；
6) in CAD software, length of the measurement crest of alveolar ridge apart from Sinus floor/mandible incisor upper limb on implantation direction
Spend the length as planting body；
7) in CAD software, measurement plantation the two sides site Jia She bone wall thickness and subtract 2-3mm as planting body can
Select maximum gauge；
8) selected planting body three-dimensional data is virtually implanted；
9) virtual plantation data are exported after manual interaction fine tuning and generate plantation guide plate corresponding with virtual plantation data
Operation auxiliary device.
Wherein, the step 3) is to be completed in CAD software with filling-up hole algorithm.
The present invention has the advantages that
It is able to achieve precisely being virtually implanted for dental implant, in conjunction with automatic measurement algorithm software, can be further realized virtual
The full-automatic digitized mine of Dental implantion helps to improve efficiency, safety and the accuracy of Dental implant surgery guide device,
And the success rate of Dental implantion reparation is improved in turn.
Specific embodiment
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
A kind of dental implant automation of the invention is virtually implanted method, there is following steps:
1) edentulous region alveolar ridge mucous membrane, adjacent teeth are obtained, to jaw tooth surface and occlusion three-dimensional data with spatial digitizer in mouth；
Edentulous region alveolar bone and adjacent teeth three-dimensional data are obtained with CT；
2) in CAD software, using remaining tooth as common region, with common region registration Algorithm, by two kinds of data fusions,
And the denture of CT scan is replaced with the denture in 3 d scan data in mouth；
3) alveolar ridge edentulous area is virtually filled and led up in CAD software；
4) it when single tooth is virtually planted, measures and defines the plant of the middle-distant direction of edentulous region, cheek-tongue direction midpoint as planting body
Angle of striking；It when polydonita is virtually planted, selects the central den of tooth to be repaired to plant site, while guaranteeing that distance is neighbouring natural
Root of the tooth 2mm；
5) in CAD software, the vertical direction of bite plane is measured as implantation direction, polydonita will also guarantee more when planting
It is parallel to each other between a planting body；
6) in CAD software, length of the measurement crest of alveolar ridge apart from Sinus floor/mandible incisor upper limb on implantation direction
Spend the length as planting body；
7) in CAD software, measurement plantation the two sides site Jia She bone wall thickness and subtract 2-3mm as planting body can
Select maximum gauge；
8) selected planting body three-dimensional data is virtually implanted；
9) virtual plantation data are exported after manual interaction fine tuning and generate plantation guide plate corresponding with virtual plantation data
Operation auxiliary device.
The step 3) is to be completed in CAD software with filling-up hole algorithm.
