If you have ever had the unfortunate incident of losing a cell phone - maybe accidentally leaving it in a bar - you probably know the frantic stress that can come with searching for the device.
By applying a matrix approach, thestress wave propagating in an elastic bar is studied.

Results: thestress values of the ball attachment in the palate area, alveolar bone and implant bone interface were much higher than that of the bar attachment.
