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

Table 2

Extreme stress values of the different parts of ferrule and nonferrule models.

	MIC (MPa)	sFRC (MPa)	mFRC (MPa)	mFRCG (MPa)
With ferrule
CRR	55.4	5.6	14.7	13.9
Interface	26.3	8.7	12.9	12.7
Root	101.4	100.6	100.8	103.1
Without ferrule
CRR	57.4	4.2	45.3	42.2
Interface	21.7	9.1	8.6	11.8
Root	134.5	156.2	130.0	131.2

Extreme stress values (ESV) are expressed in MPa 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.
