Biomechanical changes under the conditions of the loss of an implant in the canine or molar area for the mandibular overdenture on four MDIs, two of which were inserted in the canine area and two in the molar area.

	Four MDIs		Three MDIs, after the Loss of an Implant in the Molar Area		Three MDIs, after the Loss of an Implant in the Canine Area
Occlusal Loading	von Mises Stress (MPa)	Displacement (mm)	von Mises stress (MPa)	Displacement (mm)	von Mises Stress (MPa)	Displacement (mm)
On the frontal teeth (using the frontal area in mastication)	35.8	0.061	91.67	0.088	166.1	0.11
On three lateral teeth on both sides (maximum intercuspation and bilateral mastication)	40.87	0.028	55.13	0.15	50.92	0.07
On three lateral teeth on one side (unilateral mastication)	82	0.057	110.66	0.28	113.08	0.15
