Summary

Introduction: Green dentistry, is high-technology approach that reduces the environmental impact of dental practices, improper disposal of dental materials wastes results in environmental hazards.

Aim of the study: This studied will be performed o evaluate the effect of repressing of three different types of pressable ceramics, Ips Emax press, Lisi press and Celtra press with different weight percentages on patient satisfaction, mechanical properties, microstructural features and composition of these pressable ceramics.

Materials \& Methods:

Seventy five ( N=75) pressable ceramic discs will be constructed ,The samples will be divided to three groups (n=25 each) according to types and composition of pressed and repressed ceramics .Group 1: IPS Emax press .Group 2: Gc Lisipress Group 3: Celtrapress . Each group willbe divided into 5 sub-groups (n=5) according to the weight percentage of newly pressed and repressed ceramics. Subgroup A: 100% new ceramics. Subgroup B: 75% new and 25 % repressed ceramic .Subgroup C: 50% new and 50% repressed ceramics. Subgroup D:25%new and 75% repressed ceramics. Subgroup E: 100% repressed ceramics. Biaxial flexural strength will be measured using universal testing machine. X-ray diffraction will be performed to identify the crystalline phases, and a scanning electron microscope will be used to describe microstructural features. Energy dispersive X-ray analysis will be used to evaluate change in composition Also surface hardness will be evaluated. Patient satisfaction, plaque, cervical caries and marginal discoloration will be evaluated in a follow- up of one year (in vivo part).
