Brief Summary

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

Conditions

Esthetic Restorations

Keywords

Injection moulding; Veneers; Accuracy; Geomagic; resin composite

Outcome Measures

Primary Outcomes (1)

• Accuracy

  The root mean square (RMS) values were obtained through the "3D-compare" method followed by comparison at each surface point between the reference digital design desing and the final outcome using injection moulding

  From enrolment to the end of treatment after 4 weeks

Study Arms (2)

Injection moudling technique

EXPERIMENTAL

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

Procedure: Injection moulding technique

Digital smile design

OTHER

Baseline smile design

Diagnostic Test: Digital smile design

Interventions

Injection moulding technique 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.

Injection moudling technique

Digital smile design 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
