Abstract
The present invention provides a kind of method that multi-point scanning is used for dental articulation compensation data, includes the following steps：（1）Maxillary teeth is scanned using scanner, obtains maxillary teeth data；Equally lower jaw tooth is scanned using scanner, obtains lower jaw tooth data；（2）Maxillary teeth and lower jaw tooth are modeled by the data obtained in step 1；（3）After maxillary teeth is engaged with lower jaw tooth, the left cheek side of occlusal surface and right cheek side are scanned again by scanner, obtain multigroup occlusion data；（4）Preferable biting point is finally determined to occlusion data analysis, by increasing the biting point near occluding relation, can realize comprehensive compensation, more accurately occluding relation can be obtained, improve repair capsule accuracy and correction design it is correct, be also beneficial to promote oral cavity digitlization industry development.
Description
Technical field
The present invention relates to dental care technical fields more particularly to a kind of multi-point scanning for dental articulation compensation data
Method.
Background technology
Digital scan has stepped into the stomatological hospital of various scales as the important ring in oral cavity digitlization industry
And clinic, digital scanning are experienced with its high-precision, good patient, and to the good support of CAD/CAM design processing, obtain
The good support of sufferer, doctor, artificial tooth processing factory etc. is arrived, and developing prospect is good.
But there is a problem of in dentistry at present one it is more universal, that is, not accurate problem is engaged, if stung
The problem of closing inaccuracy, then leading to subsequent dummy design inaccuracy, correction design mistake, or even can not be designed,
And the reason for causing occlusion inaccurate includes mainly：1, scanner precision is bad, 2, occlusion scanning it is inaccurate, existing scanning
It is scanned outside scanner uni mouth predominantly in mouth, the bad problem of current scanline instrument precision is solved by promoting scanner quality
Certainly, therefore, the inaccurate problem of occlusion scanning is urgently to be resolved hurrily.
Invention content
The present invention is in view of the shortcomings of the prior art, provide a kind of method that multi-point scanning is used for dental articulation compensation data, energy
Enough improve is engaged inaccurate problem caused by occlusion scanning is inaccurate.
In order to solve the above technical problems, the present invention is addressed by the following technical programs：A kind of multi-point scanning is used for tooth
The method that tooth is engaged compensation data, includes the following steps：（1）Maxillary teeth is scanned using scanner, obtains maxillary teeth number
According to；Equally lower jaw tooth is scanned using scanner, obtains lower jaw tooth data；（2）By the data that are obtained in step 1 to upper
Jaw tooth and the modeling of lower jaw tooth and conjunction tooth；（3）After maxillary teeth is engaged with lower jaw tooth, again by scanner to the left cheek side of occlusal surface
And right cheek side is scanned, and obtains multigroup occlusion data；（4）Preferable biting point is finally determined to occlusion data analysis.
The step（3）In left cheek side, right cheek side and lip buccal side can also be to the scanning element of occlusal surface, pass through increase
Scanning element, with the more scan datas of determination.
Compared with prior art, the present invention has the advantages that：It is generally only done when relative to traditional scanning occlusion
The scanning of unilateral occlusal surface is only carried out in single buccal aspect, cheek side dental surface is generally all more smooth, lacks relative to occlusal surface
Abundant feature matches, therefore is easier to cause the error of splicing, therefore, increase the biting point near occluding relation, energy
Enough realize comprehensive compensation, more accurately occluding relation can be obtained, improve repair capsule accuracy and correction design
Correctly, it is also beneficial to promote the development of oral cavity digitlization industry.
Specific implementation mode
Present invention is further described in detail With reference to embodiment.
A kind of method that multi-point scanning is used for dental articulation compensation data, includes the following steps：（1）Using scanner to upper
Jaw tooth is scanned, and obtains maxillary teeth data；Equally lower jaw tooth is scanned using scanner, obtains lower jaw tooth data；（2）
Tooth is closed to maxillary teeth and the modeling of lower jaw tooth by the data obtained in step 1, and passes through data automatic identification maxillary teeth and lower jaw
The occlusion splicing of maxillary teeth and lower jaw tooth is obtained after tooth feature；（3）After maxillary teeth is engaged with lower jaw tooth, again by scanner pair
The left cheek side and right cheek side of occlusal surface are scanned, and obtain the occlusion data of left cheek side and right cheek side, when to left cheek side with
It, can be to being located at left cheek side when two groups of occlusion data deficiencies of acquisition are operated in next step with supporting and after right buccal aspect is scanned
And the multi-point between right buccal aspect is scanned and obtains multigroup occlusion data, can also include lip buccal side；（4）To being engaged number
Preferable biting point is finally determined according to analysis, to obtain more accurate occluding relation.
In above-described embodiment, it is not limited solely to the scanning of natural tooth in human oral cavity, can be also widely applied to various artificial teeth
Processing and reparation, design etc. to tooth mould occluding relation, by being scanned in human oral cavity or various artificial teeth are swept
It retouches, although the feature there are buccal aspect is few, the problem that matching may not be accurate still may be used in occlusion shooting face near zone
It is comprehensive by increasing the shooting point of occlusion, and on the basis of the occluding relation near each occlusion scanning element to keep relatively accurate
Compensation is closed, more accurate occluding relation can be obtained.
Protection scope of the present invention includes but not limited to embodiment of above, and protection scope of the present invention is with claims
Subject to, any replacement being readily apparent that those skilled in the art that this technology is made, deformation, improvement each fall within the present invention's
Protection domain.
Claims (2)
1. a kind of method that multi-point scanning is used for dental articulation compensation data, which is characterized in that include the following steps：（1）Using
Scanner is scanned maxillary teeth, obtains maxillary teeth data；Equally lower jaw tooth is scanned using scanner, obtains lower jaw
Tooth data；（2）Maxillary teeth and lower jaw tooth are modeled and are closed tooth by the data obtained in step 1；（3）Maxillary teeth is stung with lower jaw tooth
After conjunction, the left cheek side of occlusal surface and right cheek side are scanned again by scanner, obtain multigroup occlusion data；（4）It is right
Occlusion data analysis finally determines preferable biting point.
2. the method that a kind of multi-point scanning according to claim 1 is used for dental articulation compensation data, which is characterized in that institute
State step（3）In left cheek side, right cheek side and lip buccal side can also be to the scanning plane of occlusal surface.
