Definitions

  • the prior art also describes mechanical devices by means of which cosmetically relevant parameters can be detected by manually recording salmon and lip line or canine guidance as lines on a Plexiglas plate.
  • This type of recording of cosmetically relevant parameters also uses the creation of a model to then perform the dental work. Consequently, this method of modeling is associated with inaccuracies and deviations from the original situation in the mouth of the person concerned.

It is further preferred that either exclusively or additionally an image area is selected on which both the mouth part and parts of the nose can be seen. This is advantageous because it is possible to carry out a holistic tooth analysis. By including the lower part of the nose in the image area, the dental consultation and dental analysis can also be done on the basis of features of each face.

  • a small circle displayed on the touch screen is the axis of rotation and a half circle shown with two arrows pivots the axis of rotation.
  • the positioning of the midline as a technically relevant parameter serves in particular to check a possible deviation from the center of the face.
  • the smile line is preferably determined.
  • the smile line is defined by four markers.
  • the line is placed along the cutting edges of the upper row of teeth.
  • the course of the incisal edges of the maxillary anterior teeth should harmonize with the course of the lower lip.
  • the visualization makes deviations visible.
  • To determine the smile line the image displayed on the touchscreen is tapped on the left edge of the cutting edge and then tapped on the right edge of the cutting edge. A yellow line appears.
  • the two outer loops on the screen move the endpoints of the yellow line representing the smile line. With the inner two loops you move the line of the smile line.
  • the tooth color or discoloration is preferably analyzed.
  • the width of the smile is preferably determined.
  • the image is tapped on the left and right in the area of the corners of the mouth. It appear two yellow chambers each. A large circle moves the pair of clips, a small circle moves the distance between the parentheses. This determination includes the evaluation of the buccal corridor, which are shown as dark triangles on the screen, for example. If present, the brackets mark the respective dark area.
  • the tooth axes are preferably determined.
  • the image displayed on the touch screen is in each case tapped per desired tooth axis, for example six times. In each case a yellow line appears.

  • an evaluation of the tooth position and inclination takes place. Any deviations are defined and visualized by positioning or tilting the axis.
  • the golden section is preferably determined.
  • the golden section describes a harmonious width ratio of the maxillary anterior teeth (ratio: 1, 6/1, 0 / 0.6). Positioning is done by clicking, then the size is determined by dragging with your finger.
  • the image displayed on the touch screen is tapped once between the teeth. Then the image is tapped at the level of the 3er teeth.
  • a yellow section appears.
  • a middle loop appears on the screen. The middle loop moves the center of the cut, which should be placed with the horizontal one directly at the cutting edge and the vertical one at the center line between the edges.
  • the side loop which is displayed on the screen, should be pulled to the outer edge of the canine.
  • the length-width ratio is preferably determined. This serves to assess the tooth shape. In particular, a length-to-width ratio of 70-80% is ideal.
  • the assessment is made, for example, on the central incisor. The assessment can also be done on several teeth in succession. The selected tooth is tapped at the top left and bottom right of the screen - a yellow one appears Rectangle. With the loops that are shown on the screen, the rectangle is adapted to the tooth contours.
  • the interdental triangles are preferably determined. This is done by tapping each time, which causes a yellow triangle to appear which can be moved to the desired position with the circle.
  • the triangles should grow larger from the center of the face as the points of contact move from incisal to cervical. The row of teeth appears loosened.
  • the red-white ratio is preferably determined. This is used to assess the gingival course from the central incisor to the canine (on both sides). The lateral incisor should be shorter than the tangent between 1 tooth and 3 tooth.
  • tap on the left side of the screen of the touchscreen until a yellow line appears. The line is aligned with the zenith of the central incisor by means of the circle displayed on the touchscreen, and the line drawn on the touchscreen aligns the line with the zenith of the canine. Thereafter, the touch screen is tapped on the right and the determination is carried out as on the left side.
  • the gingival pills are preferably determined. This is to assess the status of the gingival papillae.
  • the interdental spaces should be well filled and no black triangles should be visible. By tapping a yellow arrow appears, which can be moved with the circle to the desired location.
