Abstract: Computer implemented method of generating a dental design, comprising: (a) capturing a facial image comprising a head of a patient and a smile; (b) displaying it as a first image; (c) capturing a 3D intraoral scan; (d) aligning the 3D scan to the head; (e) determining bounding boxes in the 3D scan, each comprising a single tooth; (f) showing a view of the 3D scan and the bounding boxes as a second image; (g) showing the bounding boxes as overlay on the first image; (i) allowing the bounding boxes to be resized/repositioned; (ii) defining a limited set of parameters to characterize the tooth inside the bounding box, and searching a number of candidate matching teeth from a 3D digital library of teeth, and proposing a candidate matching tooth; (iii) overlaying the first image with a digital representation of the proposed candidate matching tooth from the digital library.

Abstract: A computer implemented method (1000) of characterising a tooth by analysing at least one digital representation of said tooth in its clinical environment, comprising: a) determining a parameter indicative for the position of the tooth in a mouth; b) determining a limited set of parameters for describing the tooth in a clinical environment, comprising parameters indicative of a size and shape of the tooth, and parameters for describing adjacent papilla's. Computer implemented method (1100) for adding teeth to a database. Computer implemented method (1200) for determining a matching score between teeth. Computer implemented method (1300) of searching a database to find matching teeth. Computer implemented method for allowing a user to design or define a dental restoration, and producing a 3D file for producing the dental restoration. Computer program product for any of these computer implemented methods. A digital database.

Abstract: A computer implemented method of generating a dental design comprising the steps of: a) displaying a 2D image of a smile containing at least two teeth; b) displaying a plurality of visual objects, preferably including a lower curve to characterise said teeth; c) performing at least once: i) determining a limited set of parameters for said teeth based on said visual objects; ii) searching and retrieving a limited number of candidate matching teeth from a digital library; iii) proposing or selecting a matching tooth from said candidate matching teeth; vii) displaying the 2D image with an overlay of the proposed or selected matching teeth. Optionally saving the digital design, providing a 3D digital file, producing a physical object. A computer program product is described herein. A method of dental treatment is described herein.
