Physical properties:

+ Cement resistance is given by specific physical properties: resistance to compression forces ( 329 MPa ) and hardness ( 85 Rockwell ). A very high resistance to compression prevents the appearance of cracks after cementing, caused by the difference in hardness of the veneer, cement and dental tissue. High hardness and resistance to compression ensure durability and resistance to stress and the forces that are applied to ceramic veneers every day.

+ Colour stability: prevents shade pigmentation over time. Choice 2 cement stability is given by polymerization mode - strictly photopolymerization. Amines found in resins with self / dual cure are usually aromatic tertiary amines that oxidize very easily, leading to resin pigmentation in a relatively short time. Studies have confirmed that Choice 2 has a Delta E color change of less than 1.2. Any value less than 3 is not detectable by the human eye.

Figure 1 - In this study, five well-known cements were used, exposed to an accelerated aging process. Delta E ( ΔE ) measurements were compared to determine the degree of color change. The value ΔE for Choice 2 was 1.2. Any value of ΔE less than 3 is not detected by the human eye. As expected, not all cements had very good results.

Figure 2 - Rockwell hardness test was performed to determine compression resistance. Choice 2 demonstrated superior hardness and high compression resistance. Choice 2-fueled veneers are resistant to fracture. Information provided by Dr Nasser Barghi, University of Texas, San Antonio
