简要总结
The aim of the study is to evaluate the color stability of full and sectional glass ceramic laminate veneer as esthetic failure is reported to be common failure in laminate following clinical service.
The null hypothesis is that there will be no apparent change in color stability between full and sectional veneer over one year of clinical service
详细描述
The success of any esthetic restorative material depends primarily on the color match and then on the color stability of the material. color changes by time reduce the longevity and quality of restorations.
This in vivo study planned to evaluate the color stability of full and sectional glass ceramic laminate veneer using a digital shade device The primary objective of the study to evaluate the color stability of sectional glass ceramic veneer compared to full laminate veneer
