Abstract
The present invention relates to a kind of digitalized design methods of individual character function bionics corona shape, there is step: mandibular dentition on batch scanning bioocclusion, as standard form database；It scans tooth position to be repaired Tooth preparation and adjacent teeth, to jaw tooth, is denoted as data D1；Using in D1 adjacent teeth, jaw tooth is matched with data in standard form database respectively as common region, select matched data D2；It is merged with the corona data of tooth identical as tooth to be repaired position in D2 with tooth position to be repaired Tooth preparation, generates dummy primary data；In intercusping
Description
Technical field
The present invention relates to a kind of three dimensional designs of the most suitable fixed denture form of the function of corona shape, and in particular to a kind of
The digitalized design method of the bionical corona shape of sexual function.
Background technique
Existing fixed denture shape digitalized design method, is broadly divided into database method, image method and replica method, although
It is able to achieve the quick reconstruction of corona anatomic form to be repaired, but significantly insufficient for the designed capacity of individual character physiological function shape,
Not up to ideal Bionic Design target.
Summary of the invention
The object of the present invention is to provide a kind of digitalized design methods of individual character function bionics corona shape, can imitate advanced
Dentist designs the process of the bionical axial plane of tooth, working bite relation face and physiology wearing course, realizes the most suitable fixed denture of function
Quick bionic intelligence Design of digital.
In order to achieve the above object, the present invention has following technical solution:
The digitalized design method of a kind of individual character function bionics corona shape of the invention, it is characterised in that: have following step
It is rapid:
1) mandibular dentition on batch scanning bioocclusion, as standard form database；
2) tooth position to be repaired Tooth preparation and adjacent teeth are scanned, to jaw tooth, is denoted as data D1；
3) using in D1 adjacent teeth, to jaw tooth as common region respectively with normal data each in standard form database carry out
Matching selects the smallest one group of deviation as matched data D2；
4) it is merged with the corona data of tooth identical as tooth to be repaired position in D2 with tooth position to be repaired Tooth preparation, generates and repair
Body primary data；
5) in intercuspingAdjust to between jaw tooth without intersection；
6) near and far two adjacent teeths and dental arch opposite side are extracted with working bite relation face on the corona of region, and is accordingly generated to be repaired
The functional movement track of multiple tooth position；
7) the whole fantasy sport to jaw denture is guided with the motion profile；
8) the working bite relation face form with the enveloping surface moved to jaw cusp, as tooth to be repaired.So far, function is completed
Can most suitable fixed denture form three dimensional design.
The present invention has the advantages that the bionical axial plane of advanced dentist design tooth, working bite relation face and life can be imitated
The process of wearing course is managed, realizes the Design of digital of the quick bionic intelligence of the most suitable fixed denture of function.
Specific embodiment
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
The digitalized design method of a kind of individual character function bionics corona shape of the invention, it is characterised in that: have following step
It is rapid:
1) mandibular dentition on batch scanning bioocclusion, as standard form database；
2) tooth position to be repaired Tooth preparation and adjacent teeth are scanned, to jaw tooth, is denoted as data D1；
3) using in D1 adjacent teeth, to jaw tooth as common region respectively with normal data each in standard form database carry out
Matching selects the smallest one group of deviation as matched data D2；
4) it is merged with the corona data of tooth identical as tooth to be repaired position in D2 with tooth position to be repaired Tooth preparation, generates and repair
Body primary data；
5) in intercuspingAdjust to between jaw tooth without intersection；
6) near and far two adjacent teeths and dental arch opposite side are extracted with working bite relation face on the corona of region, and is accordingly generated to be repaired
The functional movement track of multiple tooth position；
7) the whole fantasy sport to jaw denture is guided with the motion profile；
8) the working bite relation face form with the enveloping surface moved to jaw cusp, as tooth to be repaired.So far, function is completed
Can most suitable fixed denture form three dimensional design.
As described above, the present invention more can be realized adequately.The foregoing is merely relatively reasonable implementations of the invention
Example, protection scope of the present invention include but is not limited to this, and those skilled in the art is any to be based on the technology of the present invention side
Unsubstantiality denaturation change is included within the scope of the present invention includes in case.
Claims (1)

1) mandibular dentition on batch scanning bioocclusion, as standard form database；
2) tooth position to be repaired Tooth preparation and adjacent teeth are scanned, to jaw tooth, is denoted as data D1；
3) using in D1 adjacent teeth, to jaw tooth as common region respectively with normal data each in standard form database carry out
Match, selects the smallest one group of deviation as matched data D2；
4) it is merged with the corona data of tooth identical as tooth to be repaired position in D2 with tooth position to be repaired Tooth preparation, at the beginning of generating dummy
Beginning data；
5) in intercuspingAdjust to between jaw tooth without intersection；
6) near and far two adjacent teeths and dental arch opposite side are extracted with working bite relation face on the corona of region, and accordingly generates tooth to be repaired
The functional movement track of position；
7) the whole fantasy sport to jaw denture is guided with the motion profile；
