Correcting Tooth Proportions

Noé Orellana DDS, PhD

Published on May 3rd 2022

As part of a year-long celebration to mark BISCO's 40th anniversary, we asked dentists to submit their best cases featuring BISCO products. 

We hope this case continues to inspire you and your team!

Case Study: Correcting Tooth Proportions

The dentist chose to use the indirect technique for this smile design for its superior mechanical behavior.

Case Description: The veneers placed in this case gave the patient a more youthful smile. 

A digital smile design was performed to decide the correct anterior tooth proportions, which included tooth Nos. 12 to. 22. Once the wax-up was complete, a silicone matrix was fabricated for the mock-up technique. The mock-up was done with bisacrylic material. Once the patient approved the mock-up, the preparations were performed, followed by double silicone impression and cementations. This was done according to BISCO instructions, which call for using rubber dam isolation to avoid contamination, allow for a clean restorative environment, correct visualization of the gingival margin during adjustment of the veneer restorations, and to facilitate the removal of excess cement. 
 
After the veneers were cemented, the final result was a beautiful and more youthful smile. The patient confirmed her satisfaction with the smile enhancement after the procedure and during the six-month follow-up consultation.
