1. A method of electronic analysis of teeth in a smile area, suited to facilitate identification of aesthetic dental treatments, comprising: performing a photographic examination of a patient's teeth according to an established series of poses and shots to generate digital images; electronically calibrating said digital images as a function of predetermined measures taken directly on the patient's teeth and/or face; performing a computer-assisted analysis of consistency of input data, such to intercept and limit errors due to incorrect measurements of actual data on the patient's teeth and/or face in order to calibrate the digital images; identifying, on said calibrated images, a defined set of characteristic reference points called landmarks or reference points and displaying said characteristic reference points on a computer display; causing an automatic electronic analysis and parameterization of said digital images, either individually or all together, with reference to said characteristic reference points as a function of significant parameters commonly recognized as decisive for aesthetic appearance of teeth; determining possible treatments to achieve a desired aesthetic improvement, parameter by parameter, with appropriate logical and numerical responses; performing a two- or three-dimensional electronic simulation of the patient's teeth that includes the desired aesthetic improvement; and screening and/or printing a complete report of said possible treatments.
