Communication: a case against underocclusion.
Hypo-occlusion is another term for underocclusion. This condition is often caused during crown-and-bridge procedures where an incorrect mounting of opposing dental casts, the injudicious polishing of the occlusal surface of a cast restoration, or the intended placement of an occlusal shim prior to the casting will guarantee a close occlusal contact--one that doesn't make contact. Hypo-occlusion may also take place during routine restorative work where the clinical operator "ditches" the restoration for assumed longevity. Implant specialists often advocate to the restorative dentist that their implants should be constructed with no lateral interferences and with a light centric contact or one that is just underocclusal contact. What exactly does this mean?
