Patent ID: 8092220

Claim:
A method for reconstructing missing, broken and/or abraded teeth by means of facial analysis to determine the shapes and sizes of the teeth in relation to the face of a patient for whom the teeth are provided, the method comprising the steps of: measuring an original width of the nasal base on the face; ascertaining a spacing between the tips of the two canine teeth of the patient from one another according to the original width of the nasal base; determining the proportional widths of a plurality of teeth from the ascertained spacing between the tips of the two canine teeth of the patient; taking one or more image records of the face; rotating the at least one image record through 180° so that the forehead is pointing downward to determine from the forehead the cutting edge of a front tooth; determining the shape and size of at least one central front tooth by measuring the contours of the image record of the face from the forehead to the chin via the cheek; reconstructing a second central front tooth from the first front tooth mirrored in a vertical line; determining a width of the nasal base and a width of a nasal root by means of the image record; dividing the width of the nasal base by the width of the nasal root; determining a value of the overall facial width of the image record; dividing the value of the overall facial width of the image record by the ratio obtained by the division of the width of the nasal base by the width of the nasal root; and reconstructing a width of at least one of two lateral incisors from the division of the value of the overall facial width of the image record by the ratio obtained by the division of the width of the nasal base by the width of the nasal root.
