Официальное название
Color Stability and Wear Resistance of Direct Flowable and Preheated Resin Composite Veneers Using the Injectable Resin Technique: A Randomized Controlled Clinical Trial.
Обзор
The aim of this study is to conduct the first clinical trial to assess the color stability and wear resistance of the highly filled injectable flowable composite materials compared to preheated conventional ones and evaluate the in vivo performance of the injectable composite technique.
Подробное описание
The design of study will be a modified split-mouth randomized clinical trial with two study groups. 20 patients will be recruited with the need of at least 6 anterior aesthetic restorations. A total of 142 restorations will be assigned into two groups. In the first group, 71 anterior teeth will be restored with flowable composite veneer restorations, and the second group 71 anterior teeth will be restored with heated composite veneer restorations. Both treatment groups will be done using the injectable resin technique. The following parameters will be evaluated at baseline, 6 months and 12 months of clinical service. Color stability will be evaluated using the Vita classical shade guide and a spectrophotometer. Wear resistance will be evaluated by measuring the volumetric material loss through superimposition of images taken at each follow up on baseline images taken by scanning of gypsum replicas using a 3D laser scanner. Clinical performance will be evaluated using the USPHS criteria. It is expected that the color stability, wear resistance and clinical performance of the heated composite restorations will be superior to the flowable restorations.
