Abstract
The present invention relates to a kind of malocclusion dentures to rescue rear three-dimensional configuration high efficiency digitlization preferred method, there is following steps: 1) mandibular dentition as standard form data establishes dental arch curve on batch scanning bioocclusion；2) 3-D scanning needs to receive the malocclusion denture of orthodontic therapy, is denoted as data D1；3) selection is a set of from step 1), is denoted as data D2；4) it is wrinkled with upper jaw palate for common region, data D2 is registered against data D1；5) three-dimensional data of every tooth corona root in data D1 is extracted, is registered against on the correspondence tooth of data D2, generate preliminary preferred result data；6) the near and far contact relation of every tooth bizet is adjusted, final preferred result data are generated；7) die sinking will be turned over after the printing of preferred result data three-dimensional, the entity of preferred result is presented directly in patient's oral cavity model.The present invention is able to achieve digitlization correction diagnosis and treatment process, improves the function aesthetics preferred levels of operator.
Description
Technical field
The mode of priority is digitized after rescuing the present invention relates to a kind of malocclusion denture, and in particular to a kind of malocclusion tooth
Column rescue the rear three-dimensional configuration high efficiency digitlization mode of priority.
Background technique
In the prior art, the mode of priority that malocclusion denture is rescued, generally requires the experience by doctor to complete,
Problem: first is that rescue rear three-dimensional configuration manufacturing process more complicated for denture, it is easy to appear mistake；Second is that needing the long period could
It completes, working efficiency is low；Third is that the denture that cannot be preferentially beautified；Fourth is that cannot be used for digitlization correction diagnosis and treatment process,
The function aesthetics preferred levels of operator cannot be improved.
Summary of the invention
The object of the present invention is to provide a kind of malocclusion dentures to rescue rear three-dimensional configuration high efficiency digitlization preferred method,
Denture can be simplified and rescue rear three-dimensional configuration manufacturing process, improve precision；Deadline is short, and working efficiency is higher；It can obtain preferential
The denture of beautification；It is able to achieve digitlization correction diagnosis and treatment process, improves the function aesthetics preferred levels of operator.
In order to achieve the above object, the present invention has following technical solution:
A kind of malocclusion denture of the invention rescues rear three-dimensional configuration high efficiency digitlization preferred method, there is following step
It is rapid:
1) batch 3-D scanning is located at mandibular dentition on the bioocclusion of intercuspal position, as standard form data, surveys
The numerical value for measuring the sum of near and far diameter of every secondary template all teeth of list jaw denture, selects foundation as template, establishes dental arch curve；
2) 3-D scanning needs to receive the malocclusion denture of orthodontic therapy, is denoted as data D1；It is all to measure single jaw denture
The numerical value of the sum of the near and far diameter of tooth；
3) selection is a set of identical or closest as wait rescue the sum of single near and far diameter of jaw tooth numerical value from step 1)
Standard form data are denoted as data D2；
4) it is wrinkled with upper jaw palate for common region, with common region registration Algorithm, data D2 is registered against data D1；
5) three-dimensional data of every tooth corona root in data D1 is extracted, is registered against the correspondence tooth of data D2
On, generate preliminary preferred result data；
6) the near and far contact relation of every tooth bizet is adjusted, when data interference occurs, by remote Tooth along dental arch song
Line sliding, until no interference, generates final preferred result data；
7) die sinking will be turned over after the printing of preferred result data three-dimensional, preferred result is presented directly in patient's oral cavity model
Entity.
The present invention has the advantages that can simplify denture rescues rear three-dimensional configuration manufacturing process, precision is improved；Deadline
Short, working efficiency is higher；The denture that can be preferentially beautified；It is able to achieve digitlization correction diagnosis and treatment process, improves operator's
Function aesthetics preferred levels.
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 malocclusion denture of the invention rescues the rear three-dimensional configuration high efficiency digitlization mode of priority, there is following step
It is rapid:
1) batch 3-D scanning is located at mandibular dentition on the bioocclusion of intercuspal position, as standard form data, surveys
The numerical value for measuring the sum of near and far diameter of every secondary template all teeth of list jaw denture, selects foundation as template, establishes dental arch curve；
2) 3-D scanning needs to receive the malocclusion denture of orthodontic therapy, is denoted as data D1；It is all to measure single jaw denture
The numerical value of the sum of the near and far diameter of tooth；
3) selection is a set of identical or closest as wait rescue the sum of single near and far diameter of jaw tooth numerical value from step 1)
Standard form data are denoted as data D2；
4) it is wrinkled with upper jaw palate for common region, with common region registration Algorithm, data D2 is registered against data D1；
5) three-dimensional data of every tooth corona root in data D1 is extracted, is registered against the correspondence tooth of data D2
On, generate preliminary preferred result data；
6) the near and far contact relation of every tooth bizet is adjusted, when data interference occurs, by remote Tooth along dental arch song
Line sliding, until no interference, generates final preferred result data；
7) die sinking will be turned over after the printing of preferred result data three-dimensional, preferred result is presented directly in patient's oral cavity model
Entity.
The bioocclusion (normal occlusion), including individual normal occlusion and ideal normal occlusion.
Individual normal occlusion: all slight patho-occlusions, for physiology course without big intruder, all can example enter normal tooth
Scope is closed, the individual tooth in this normal scope closes, and has different, therefore referred to as individual normal occlusion each other.
Ideal normal occlusion: saving full tooth, and tooth arranges very neat on upperdental arch, the Jian Woguan of upper lower tooth
System is completely correct, and the tooth conjunction relationship of upperdental arch is ideal, referred to as ideal normal occlusion.
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.
