        Article history:                   Background: In multidisciplinary dentistry, it is common to observe clinical cases that present
        Received: July 1, 2024             multiple complications at the end of orthodontic therapy, such as differences in gingival height,
        Accepted: October 8, 2024          alterations in size and shape of the teeth, and reduced residual spaces for implant therapies.
        Published Online: October 24, 2024  Aim: The aim of the study was to solve an esthetic case with the help of digitally assisted prosthetic
                                           and surgical design.
        Keywords:                          Methods: A young patient had been treated orthodontically for the agenesis of tooth 12 and the
        Computer-guided implantology       conoid shape of tooth 22. Previous therapy consisted of opening the space for tooth 12 by positioning
        Surgical diagnosis and design software  a  Maryland-type  composite  bridge,  followed  by  reconstruction  with  a  composite  of  tooth  22.

        Artificial intelligence            elements had discordant coronal axes, the diastema was observed at the incisal level, and tooth 21
        Lithium disilicate veneers         was approximately 1 mm longer than tooth 11. Radiographic analysis revealed that the roots of
                                           teeth 11 and 13 converge, providing sufficient space for the insertion of a small-diameter implant.

                                           Relevance for Patients: Digital techniques are now widely used across all fields of dentistry. This
                                           has led to the need for operators of all ages to adjust their decision-making process compared to
                                           traditional techniques. These new techniques have also improved communication with patients,
                                           allowing  the  dental  team  to  have  a  clearer  understanding  of  the  clinical  path  to  follow  and
                                           consequently offer their patients precise dentistry solutions.
