Multi-Fiber-Reinforced Composites for the Coronoradicular Reconstruction of Premolar Teeth: A Finite Element Analysis

Table 3

Risk of fracture of different parts of ferrule and nonferrule models.

	MIC	sFRC	mFRC	mFRCG
With ferrule
CRR	0.38	0.37	0.15	0.14
Interface	8.76	0.58	0.90	0.84
Root	0.98	0.96	0.96	0.99
Without ferrule
CRR	0.40	2.80	0.45	0.42
Interface	7.23	0.61	0.57	0.79
Root	1.29	1.50	1.25	1.26

The risk of fracture is expressed for MIC (metal inlay core), single-fiber-reinforced composite (sFRC), multifiber-reinforced composite (mFRC), and multifiber-reinforced composite with gutta (mFRCG) for ferrule and nonferrule models.
