Click “measurement analysis” on the workflow bar to generate the automatic analysis result.
Dental Crowding
Check the malocclusion situations. A pop-up can show all information for users, including dental arch and tooth width. You can check the measurement results and tell the crowding situation.
General standards are as shown below.
Dental Crowding (mm) | Class |
0<a≦4 | I (Mild Crowding) |
4<a≦8 | II (Moderate Crowding) |
8<a | III (Severe Crowding) |
The program empowers users to modify the arch lines and tooth width manually. Click the arch line on a model, a sub-window will appear in the lower right corner. You can move the points to adjust the arch line carefully.
You can modify the width of the teeth. Move your cursor on a tooth, and the width of the tooth will appear. Click the tooth that you want to modify, and rotate the tooth in the sub-window to adjust the width. Subsequently, the measurement results will be changed simultaneously.
Bolton Ratio
The Bolton Ratio serves as a tool for determining tooth size abnormality. The Bolton Ratio mainly provides the anterior ratio and the overall ratio, and a pop-up will show the results for measurements.
General standards are as shown below.
Bolton Ratio | Default Template 1 | Default Template 2 |
a | 78.8±1.72% | 77.2±1.65% |
o | 91.5±1.51% | 91.3±1.91% |
You can switch default templates in the settings> template. The default template 2 is applicable to Chinese. Similar to dental crowding, you can also modify the width of teeth.
Overbite and Overjet
Check the overbite and overjet conditions. A measurement table will show all results.
And the general standards are shown as below.
Overbite | Class | Overjet(mm) |
Within incisal edge 1/3 | I | 3~5 |
Within incisal edge 1/3~2/3 | II | 5~7 |
Over incisal edge 2/3 | III | >7 |
The red lines on the mandibular teeth divide teeth into 3 parts, which can intuitively show the overbite conditions.
The program can calculate the distance between the mesiobuccal points of the maxilla and mandible or the middle points of the incisal edge in the maxilla and mandible. You can click the results in the measurement table, subsequently, the corresponding teeth will be highlighted, and the sub-window will show the details of the teeth in the lower right corner.
Molar Relationship
A measurement table can provide the judgment of the relationship of the first permanent molar on both side.
Click the points on models or the results in the measurement table, a sub-window will appear to show the detailed conditions of molars. In general, the molar relationships could be divided in neutral, mesial and distal relationships.
Tips:
The 2 grey straight lines on both sides can assist users in telling the relative positions of the mesiobuccal cusp in the maxilla and the buccal groove in the mandible.
Curve of Spee
The program simulated a fitted curve of Spee and planes, and automatically calculated the distance from the lowest point of the curve to the plane, namely, the depth of the curve of Spee. In general, the standard of the depth is limited to 2±0.7 mm.
Users can drag the points to adjust the incisor edges, canine cusps, molar buccal cusps and the shape of the curve. Simultaneously, the results will be changed.
