The loss of a tooth can generate the displacement of the neighbouring teeth as well as those that would crush or rub against it which causes a distortion of the occlusion (the way the upper teeth link or interlock with the lower or near teeth). The successive loss of teeth brings along a deterioration in normal functions such as chewing, swallowing and speech impediment. The stomach is the organ that will suffer most because it will have to replace the teeth to accomplish the task of chewing food.
The recovery of those functions through the replacement of the lost teeth can be done through implants, lag screws of titanium biocompatible with the root bone and able to perform the task, from a single tooth in an individual implant to a general rehabilitation in the case of many implants.
