Device and method for subgingival measurement |
摘要 |
A method for measuring regions of a tooth in a mouth including: measuring at least one surface point on a surface of the tooth with respect to an element mechanically coupled to said surface point; determining a location of at least one visible reference mechanically coupled to said surface point with respect to said element; estimating a location of said surface point with respect to said visible reference. A device used for such measuring may include a main body comprising a final optical element of an imager which defines an optical field of view directed in a first direction; and a measurement element coupled to said main body extending generally in said first direction; where a tip of said measurement element is sized and shaped to be inserted between a tooth and adjacent gingiva; where said optical field of view is sized to image at least part of a tooth. |

1. A device for measuring regions of a tooth comprising:
a main body comprising a final optical element of an imager which defines an optical field of view directed in a first direction; an elongate measurement element coupled to said main body and extending generally in said first direction; and circuitry for estimating a movement of a tip relative to said body based on an image acquired via said imager; wherein said tip of said measurement element is sized and shaped to be inserted between a tooth and adjacent gingiva; wherein said a distance between said tip and said body is small enough so that said device can fit inside an adult human mouth; and wherein said optical field of view is sized to image at least part a tooth when such tooth is contacted by said tip. |
