Evaluating the Mechanical Properties Between Printable Resins of Differing Ceramic Particle Compositions

Figure 1: The maximum force that rods of increasing ceramic concentration withstood was determined in a 3-point flexure test. Control and 20% resin samples were not significantly different, but both were significantly less than the 50% resin sample. Data represent mean ± sem of n=15 per group.

Figure 2: The maximum force that buttons of increasing ceramic concentration withstood before breaking off of a 3D-printed premolar was determined. The 20% and 50% resin samples were not significantly different, but both were significantly more than the Control sample. Data represent mean ± sem of n=15 per group.

Table 1. Pins remaining on premolars after buttons debonded. The score represents the range of the number of pins that were present on the premolar.
