Abstract
A method of providing an accurate three-dimensional scan of a dental arch area is disclosed. The arch area has two segments and a connecting area between the two segments. The connecting area has homogeneous features. A connecting-geometry tool with at least one definable feature is affixed to the arch area. The definable feature overlays at least part of the connecting area. The arch area is scanned to produce a scanned dataset of the arch area. The definable feature of the connecting-geometry tool on the connection area is determined based on the scanned dataset. The dimensions of the arch area are determined based on the data relating to the definable features from the scanned dataset.
Claims20
A method of providing a three-dimensional scan of a dental arch area, the arch area having two segments and a connecting area between the two segments, the method comprising:
- affixing a connecting-geometry tool with at least one definable feature relative to the dental arch area, the at least one definable feature overlaying at least part of the connecting area;
- scanning the arch area to produce a scanned dataset of the arch area;
- determining data relating to the definable feature of the connecting-geometry tool overlaying the connecting area based on the scanned dataset;
- and
- determining the dimensions of the connecting area based on the data relating to the definable feature.
A system for producing a scanned dataset of a dental arch area, the dental arch area including two segments and a connecting area between the two segments, the system comprising:
- a controller;
- an intra-oral scanner coupled to the controller;
- a connecting-geometry tool affixable to the dental arch area to overlay the connecting area, the connecting-geometry tool including at least one definable feature;
- and
- wherein the controller is operative to accept scan data from the intra-oral scanner and determine the dimensions of the connecting area based on data relating to the definable feature.
