Article Synopsis
- - The study evaluated how different ceramic materials (lithium disilicate glass-ceramic—IPS e.max CAD vs. IPS e.max Press) and resin cement shades affect color changes in laminate veneers.
- - Researchers prepared 40 veneer samples, divided them into groups based on material and cement shade, and measured color changes using a colorimeter before and after cementation.
- - Results showed that IPS e.max Press veneers had more significant color changes compared to IPS e.max CAD veneers, particularly with the B1 cement shade showing the greatest color change, indicating that material and cement shade selection is crucial for minimizing color alterations.
Objectives: Mechanical properties are cardinal for the long-term clinical success of laminate veneer restorations but the selection of new restorative materials should ideally be based on clinical evidence, therefore, in vitro testing of dental materials is a good alternative to evaluate their properties and understand their behavior so this study aimed to compare and evaluate the effect of two different thicknesses and yttria percentage on the fracture resistance of laminate veneer zirconia restorations.
Materials And Methods: Forty laminate veneer restoration prepared from partial sintering zirconia of 3Y (yttria), 5Y (yttria), combined 3Y&5Y (yttria), and lithium disilicate. Specimens were assigned into four main groups according to their percentage of yttria content (n = 10) and subgrouped into two thicknesses (0.
