Accuracy of Injection Moulding Technique

Not Applicable

Completed

• Conditions: Esthetic Restorations

• Registration Number: NCT07180732
• Lead Sponsor: NewGiza University

Brief Summary

To evaluate the discrepancy between the digital smile design (DSD) and the resulting direct composite veneers via Injection Moulding Technique.

Detailed Description

This study will be aiming at testing the accuracy of the injection moulding technique compared with the digital smile design, therefore improving the outcome of composite veneers for the patients in order to reach more predictable results. Utilizing a quantitative method to assess accuracy of Injection moulding technique is deficient in literature and using a geometrical subtraction software will be an objective method to compare the difference with the digital smile design.
