Status data dentulous, the current denture data after being detected, the current denture data are according to scheduled denture number
It further include current dental property parameters according to the current dental status data that format generates；
After being detected to current dental, by the detected status of each tooth in denture according to aforementioned predefined
The format of AA-B-C-DD is encoded, so that the denture coded data after being detected, re-records when other of labial teeth condition are related
Property parameters.In one embodiment, association attributes parameter includes age, the gender etc. of corresponding tooth owner.
Step S2 can also be according to the setting requirements of subsequent step first to current portion dentulous, institute in one embodiment
Dtex sign is detected, such as only acquires the deletion condition of denture, so as in the next steps just for for placing card
The non-missing tooth of ring carries out the acquisition and analysis of other property parameters, thus when saving computing cost and data collection and analysis
Between.
S3 successively analyzes the data of the flag bit of each numbering teeth according to the current denture data of acquisition, root
According to the optimal artificial tooth attribute of its Corresponding matching of the numerical analysis of each respective flag position, obtained after having analyzed all flag bits just
Walk dentures repai numbering plan；
Further step S3 is described in detail as follows:
S3.1 generates current denture status data AA- according to preset denture data format in abovementioned steps
B-C-DD first analyzes AA and B, and AA expression tooth positions, its data indicate tooth position, B expression teeth
Tooth whether there is (there are 1/ missings 0), thus first AA and B analyze substantially be to each tooth first whether
There is missing to be analyzed, to filter out the preliminary artificial tooth scheme that can be suitable for repairing missing tooth position, tables of data
Up to for EE-F-G-HH, concrete analysis includes the following steps:
S3.1.1 first determines whether there are the tooth position of which missing and judges the affiliated subregion of target tooth position；
It indicates that its corresponding AA tooth lacks when B data are 0, indicates its corresponding AA tooth when being 1
It does not lack, thus identify that all tooth position AA-0-X-X lacked and as the target tooth further analyzed
Position；
Denture is divided into four areas, including 1st area of the upper jaw, 2nd area of the upper jaw, 3rd area of lower jaw, 4th area of lower jaw, AA indicate when being 1X
1st area of the upper jaw, AA indicate 2nd area of the upper jaw when being 2X, AA indicate 3rd area of lower jaw when being 4X, AA indicate 4th area of lower jaw when being 4X；
S3.1.2, judges whether missing tooth position belongs to non-subclass；
When AA are X7 and B are 0, tooth position missing belongs to the free deletion of non-subclass, while also needing further to sentence
Break the specific generic of the non-subclass free deletion, and preliminary screening goes out all be suitable for from dentures repai scheme database
The recovery scenario of all non-subclass free deletion classifications and the number expressional scheme { EE-F-G- for obtaining all recovery scenarios
HH }, { } indicates set；
S3.1.2.1, when AA-B data be the upper jaw in 17-0&27-0 exist simultaneously or lower jaw in 37-0&47-0 simultaneously
In the presence of then tooth position missing belongs to the bilateral free deletion of Ken Shi I class；
S3.1.2.2, when AA-B data be in the upper jaw 17-0 or 27-0 exist and 17-0&27-0 do not exist simultaneously or under
37-0 or 47-0 exists in jaw and 37-0&47-0 does not occur simultaneously, then the unilateral side that tooth position missing belongs to Ken Shi II class, which is dissociated, to be lacked
It loses；
S3.1.2.3, when AA-B data be the upper jaw in without 17-0&27-0 exist or lower jaw without 37-0&47-0 in the presence of,
Then tooth position missing belongs to Kennedy III, the non-free missing of IV class.
S3.1.3, further judges whether missing tooth position belongs to subclass, and is adjusted according to differentiation classification to recovery scenario
It is whole；
S3.1.3.1, when the tooth position, missing has been identified as Ken Shi I class in a previous step, if existing simultaneously PQ-1-
X-XX it is close in there are missing tooth PR-0-0-00, PQ-1=PR, then the tooth position missing be further considered to belong to subclass, at this time
Corresponding deformation adjustment is carried out to the dentures repai scheme of the suitable non-subclass of Ken Shi I class, obtains the preliminary artificial tooth of Ken Shi I class subclass
Recovery scenario；Such as be the tooth condition of 15-17,25-27,13 missings for tooth position missing data, if 17-0-0-00&27-0-0-00
Occur simultaneously, be identified as Ken Shi I class, matches design (15-17,25- of first edentulous region that two sides encounter from back to front at this time
27 missings), if 14-1-0-00 and 13-0-0-00 occurs simultaneously, tooth position missing is identified as Ken Shi I class subclass, at this time scarce
It loses tooth (13) two sides abutment (14.12) default and places three-arm clasp, i.e. EE=12,14, HH=01；
S3.1.2.2, when the tooth position, missing has been identified as Ken Shi II class in a previous step, if there is PQ-1-X-XX
It is close in there are PR-0-0-00, PQ-1=PR, then the tooth position missing be further considered to belong to subclass；Such as tooth position 15-
17, the tooth condition of 13 missings, if 17-0-0-00 individually occurs, tooth position missing is identified as Ken Shi II class, matches two sides at this time
The design (15-17 missing) of first edentulous region encountered from back to front；If 14-1-0-00 and 13-0-0-00 occurs simultaneously,
Tooth position missing is identified as Ken Shi II class subclass, defaults in missing tooth (13) two sides abutment (14.12) place three arm cards at this time
Ring；
When the tooth position, missing has been identified as Ken Shi III, IV class to S3.1.2.3 in a previous step, then matches two sides and encounter
First edentulous region design, if there are also other tooth positions lack, missing tooth two sides default place three-arm clasp.
If the judgement of S3.1.4 missing tooth position belongs to subclass, further determines whether other problems occur and accordingly be adjusted
It is whole；
If the abutment that closes on of the subclass tooth position S3.1.4.1 also lacks, the direction Xiang Jinzhong is jumped；
If S3.1.4.2 different recovery scenarios occurs to same tooth, (> symbol indicates excellent to setting snap ring priority
It is first), such as:
1) snap ring group priority is RPI (21)/RPA (22) > tri- arm (10.01)；
2) priority ratio of snap ring and rest more snap ring (XX) > rest (31.32.33)
If S3.1.4.3. abutment be premolar teeth (X4-0-0-00.X5-0-0-00) or first molar (X6-0-0-00),
Three-arm clasp (01.10) is replaced with into half and half clasp (05).
Next S3.2 divides for placing the corresponding tooth condition data in tooth position C of snap ring in Primary screening setup
Analysis, due to C expression Movable degrees (not loose 0/ loosens 1), carrying out analysis essence to C data first is the loosening to tooth
Situation is analyzed, and judges it if appropriate for for placing snap ring, and according to the adjustment for loosening situation and carrying out recovery scenario, in number
It is expressed as being adjusted each flag bit data of Project expressing EE-F-G-HH on word logical expression.
Indicate that I ° of class does not loosen, and does not carry out any modification to snap ring scheme at this time when C data=0；
Indicate that II °/III ° class loosens, and needs to jump periodontal splint at this time, after jumping when C data=1
Tooth position position, that is, EE data are adjusted correspondingly.
If desired it jumps, then jumping direction is the direction far from missing tooth position, and the selection of snap ring HH is needed into one
Step judgement is as follows:
1) if snap ring of the same name exists, snap ring of the same name is directlyed adopt；
If 2) snap ring of the same name is not present, three-arm clasp is used.
For example, since snap ring could be placed only in natural teeth, if there is a ring (EE=16) on No. 16 tooth positions,
It has loosened (C=1), then needs to jump on No. 15 tooth positions (EE=15), if just also there are a ring clasp in No. 15 tooth positions,
So just selection ring clasp (HH=02), if no ring clasp on No. 15 tooth positions, that just selects three-arm clasp (HH=
01)。
S3.3 further judges whether tilt for the tooth position for placing snap ring, due to DD expression inclined directions,
Which kind of selection or adjustment can be analysed whether to tilt and need to carry out recovery scenario by analyzing DD data,
It is expressed as being adjusted each flag bit data of Project expressing EE-F-G-HH in Digital Logic expression；
Be divided into two kinds of cheek-tongue directions, middle-distant directions in the case where firstly for inclination the present embodiment, for DD data and
