Randomized Clinical Trial on Direct Composite and Indirect Ceramic Laminate Veneers in Multiple Diastema Closure Cases: 2-years Follow-up

Brief Summary

Detailed Description

Restorative materials and curing device In the current study, the manufacturer's instructions were followed for the use of the nanofilled composite resin (Estelite Asteria, Tokuyama Dental, Japan) for direct laminate veneers and IPS e.max Press (Ivoclar Vivadent, Amherst, NY, USA) for indirect laminate ceramic veneers. A light curing device with an output density of 655 mW/cm2 (LED Bluephase C5, Ivoclar, Vivadent, Amherst, NY, USA) was used. Demetron LED light meters were used to measure the light curing unit's intensity regularly (Demetron Research Corp., Danbury, CT, USA). Brand name, description, chemical composition, and manufacturers of the materials are presented in Table 1. Study design, blinding \& randomization The Consolidated Standards of Reporting Trials statement was adhered to in the description of the experimental design. This study was a randomized controlled clinical trial that was double-blinded for both trial participants and outcome assessors. Randomization was performed using the flip of a coin for the choice of material. Using computerized sequence generating (www. randomizer.org), participants were divided into two groups with a 1:1 allocation ratio.
