1 Dental implants can also promote dental health. 2  When a tooth is missing, the jaw bone is not stimulated, which can cause the bone to deteriorate. 3  An implant stimulates the bone as a natural tooth would, helping to prevent bone loss.
Longitudinal waves, also known as l-waves, are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave.
In a longitudinal wave, the motion of the medium is parallel to the direction of the wave. This means that the particles move left and right which in turn makes the other particles start to oscillate.
