DIGITAL SMILE DESIGN (DSD) AND WAX UPĀ : DETERMINING THE LATERAL INCISORS DIMENSIONS (image 2)
This step must be done during the orthodontic phase, at the stage of the last finishes. Using the DSD, we can determine the ideal dimensions of the future restoration (height and width), its morphology and gingival margin. The DSD also allows us to determine if modifications to other anterior teeth are necessary.
When the DSD is validated by the practitioner and the patient, it will be communicated to the orthodontist in order to guide him/her in the position of the anterior teeth. In order to facilitate the movement of the riziform tooth, the DSD can be transformed into a wax up and then mock up if the situation permits (29,30). In our clinical case the DSD was not performed because it would not provided us with any additional information.
