Al-Azhar Journal of Dentistry

Purpose: The purpose of the current study was to evaluate marginal accuracy and color stability of lithium disilicate laminate veneer compared to hybrid ceramic veneer. Materials and Methods: Forty maxillary teeth were collected and prepared (but joint preparation) to receive a laminate veneer. They were equally sub grouped (n= 20) to receive 2 types of laminate veneers (IPS E-max CAD and vita enamic). The veneer was milled from the blocks in a CEREC 3 Machine.
