Abstract: Disclosed is a computer implemented method for generating a dental appliance comprising: - obtaining a first 3D digital surface representation of one or more teeth of a patient; - creating a number of points in 3D space around the 3D digital surface representation, - calculating the shortest distance from each of the points to the 3D digital surface representation; - generating a modified 3D digital surface representation by dilating the surface of the object a defined value by using the calculated distances; and - generating a resulting 3D digital surface representation of the dental appliance by erosion of the modified 3D digital surface representation inwards.
