DSD is a technical tool which is used to design and modify the smile of patients digitally and help them to visualise it beforehand by creating and presenting a digital mockup of their new smile design before the treatment physically starts. Digital imaging and designing helps patients to visualize the expected final result before the treatment itself starts which enhances the predictability of the treatment. It also helps to evaluate and compare pre and post treatment changes. The patient can evaluate, provide opinion, and approve the final shape of the new smile before any treatment procedures are performed thus enhancing patients satisfaction. A design created digitally involves participation of the patients on the designing process of their self-smile design, leading to customization of smile design as per individual needs and desires, relating patient to an emotional level, increasing their confidence in the process and better acceptance of the anticipated treatment. Hence Digital smile design concept is a helpful tool in aesthetic visualization of patient’s problem.
