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.

Study Groups

Injection moudling technique

A dental procedure where a patient-approved tooth shape, established from a diagnostic wax-up, is replicated using a transparent silicone index

Group Type: EXPERIMENTAL

Injection moulding technique

Intervention Type: PROCEDURE

A dental technique that uses a transparent silicone index or stent to inject a low-viscosity composite into a pre-planned and approved tooth shape.

Digital smile design

Baseline smile design

Group Type: OTHER

Digital smile design

Intervention Type: DIAGNOSTIC_TEST

A modern approach that uses digital imaging, videos, and software to create a customized, virtual 3D model of a patient's ideal smile before any treatment begins
