Abstract
The present invention relates to a kind of jaw relationship digital reconstruction methods based on tooth crowding analysis, comprising: uses tooth crowding recording device records rest position tracing point, record lower jaw habituation is opened and closed mouth motion profile line collection；The highest trajectory line of multiplicity is found on trajectory line collection, and extracts subpoint of the rest position tracing point on the line；The top trace point with subpoint at a distance of 2-4mm is found in trajectory line, is denoted as data 1；Lower jaw plaster cast in scanning obtains model scanning data, is denoted as data 2；Data 2 are registered against data 1；It obtains and is located at a upper mandibular model scan data for sexual compatibility jaw relationship.Present invention digital reconstruction and the jaw relationship designed and produced substitute traditional bite plate production method, it can objective in a short time, accurate, directly measure the jaw relationship between the upper lower jaw of patient, data are provided for subsequent digitation design and fabrication artificial tooth, improve the efficiency and precision of jaw relationship three-dimensional reconstruction.
Description
Technical field
It the present invention relates to a kind of jaw relationship digital reconstruction and designs and produces, and in particular to one kind is based on tooth crowding
The jaw relationship digital reconstruction method of analysis.
Background technique
Full occlusion of dentition is rebuild when repairing, jaw relationship digital reconstruction and to design and produce be very crucial one of step.
By taking edentulous jaw complete denture restoration as an example, in conventional method, the method made of bite plate, step is very cumbersome, and jaw
Position relationship all has personalization features, in practice, does not implement personalized jaw relationship digital reconstruction and designs and produces, be difficult
Meet clinical requirement.
Summary of the invention
The object of the present invention is to provide a kind of jaw relationship digital reconstruction methods based on tooth crowding analysis, use number
The jaw relationship that word is rebuild and designed and produced substitutes traditional bite plate production method, realizes that clinical oral produces artificial tooth jaw position automatically
The target of relationship personalized function can objective in a short time, accurate, directly measure the jaw relationship between the upper lower jaw of patient,
Data are provided for subsequent digitation design and fabrication artificial tooth, the efficiency and precision of jaw relationship three-dimensional reconstruction is improved, effectively improves
The clinical treatment operating technology of base doctor is horizontal, improves diagnosis and treatment efficiency and quality.
In order to achieve the above object, the present invention has following technical solution:
A kind of jaw relationship digital reconstruction method based on tooth crowding analysis of the invention, comprising the following steps:
1) tooth crowding recording device records rest position tracing point is used, record lower jaw habituation opening and closing mouth moves rail
Trace collection；
2) the top trace point with subpoint described in step 2) at a distance of 2-4mm is found in the trajectory line, is denoted as data
1；；
3) the top trace point with subpoint at a distance of 2-4mm is found on track, is denoted as data 1；
4) upper lower jaw plaster cast is scanned, model scanning data is obtained, is denoted as data 2；
5) data 2 are registered against data 1；It obtains and is located at a upper mandibular model scan data for sexual compatibility jaw relationship；
6) data are provided for subsequent digitation design and fabrication artificial tooth, to improve the efficiency and essence of jaw relationship three-dimensional reconstruction
Degree.
Wherein, the upper lower jaw plaster cast of the step 4) is that the pre-production completed in step 1) is completed.
The present invention has the advantages that
Traditional bite plate production method is substituted with digital reconstruction and the jaw relationship designed and produced, realizes that clinical oral is automatic
The target of complete denture jaw relationship personalized function is produced, the upper lower jaw of patient can objective in a short time, accurate, be directly measured
Between jaw relationship, provide data for subsequent digitation design and fabrication artificial tooth, improve the efficiency of jaw relationship three-dimensional reconstruction
And precision, the clinical treatment operating technology for effectively improving base doctor is horizontal, improves diagnosis and treatment efficiency and quality.
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 jaw relationship digital reconstruction method based on tooth crowding analysis of the invention of the invention, including with
Lower step:
1) tooth crowding recording device records rest position tracing point is used, record lower jaw habituation opening and closing mouth moves rail
Trace collection；
2) the highest trajectory line of multiplicity is found on trajectory line collection, and extracts throwing of the rest position tracing point on the line
Shadow point；
3) the top trace point with subpoint described in step 2) at a distance of 2-4mm is found in the trajectory line, is denoted as data
1；；
4) upper lower jaw plaster cast is scanned, model scanning data is obtained, is denoted as data 2；
5) data 2 are registered against data 1；It obtains and is located at a upper mandibular model scan data for sexual compatibility jaw relationship；
6) data are provided for subsequent digitation design and fabrication artificial tooth, to improve the efficiency and essence of jaw relationship three-dimensional reconstruction
Degree.
The upper lower jaw plaster cast of the step 4) is that the pre-production completed in step 1) is completed.
Tooth crowding recording device or tooth jaw motion profile recording device can improve data precision and expand tooth
The covering surface of jaw；It is easy to use；It can stablize, accurately and reliably reappear mandibular centric relation position；Lower jaw can be reappeared to the upper jaw
Various eccentric relations；It can reappear, simulate individual patients mandibular movement feature.
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.
