About this study

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.

Treatment and study plan

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.

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

Primary outcomes

  1. Accuracy

    Time frame: From enrolment to the end of treatment after 4 weeks

    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
