Abstract: A computer-aided method for designing a surgical template for dental and/or orthodontic implants comprises acquiring a first 2D or 3D image of the oral cavity and of the overlying anatomical structures of a patient, processing the first image for defining one or more second 2D images showing corresponding views or sections of the oral cavity, realizing a digital model of the upper dental arch and of the palate of the patient to identify one or more suitable sites for inserting a corresponding implant, selecting one or more slices of the digital model at one or more sagittal or parasagittal planes passing through respective insertion sites, overlapping the slices with corresponding second 2D images for generating a third 2D image, providing a digital library of implants for the selection thereof and for their virtual positioning into the third image in order to allow the adjustment of the inclination and/or the deepness of insertion.
