A case of report of esthetic restoration of anterior maxilla applying digital smile design

<p>I.Objective: The digital information from the Digital Smile Design (DSD) was employed to determine the position of the maxillary central incisal edge for the patient with esthetic disorders in the maxillary anterior region, and the final superstructure was designed in consideration of the teeth with poor prognosis and the direction of placement of the existing implants in harmony with the facial configurations and lips. II. Methods: A 47-year-old female patient presented with the chief complaint of loss of lateral incisor. 1 was elongated and only a residual root was seen in the 2 site. The maxillary anterior teeth showed poor esthetics when smiling due to irregular morphology of the gingival margin. An implant placed 22 years earlier was present in 1 . Cone beam computed tomography (CBCT) showed X-ray transmission at the root apex of 2 and 1 , and their prognoses were judged to be poor——hence the following treatment plan: 1 to be replaced with immediately placed implant along with immediate provisionalization, and 2 to be extracted and six maxillary anterior teeth to receive crown restorations. III. Results: The DSD was employed in the examination and diagnosis, and esthetic restorations of the maxillary anterior teeth were performed in harmony with the patient's facial configurations and lips. IV. Discussion and Conclusion: The application of DSD enabled us to determine the threedimensional placement position of the implants in consideration of the morphology of the final prostheses, which were in harmony with her facial configurations and lips. We believe that the patient's understanding of and satisfaction with the treatment were improved by the visual approach. </p>
