Why does maxilla or mandible atrophy?
The loss of single or multiple teeth is one of the reason for the occurrence of mandible or maxillary bone atrophy. Then, atrophy processes occur in the bone surrounding extracted teeth. Maxilla and mandible without a tooth remain unloaded functionally, do not take part in physiological functions, e.g. mastication. And – similarly to muscle tissue that is not used – atrophy, as unloaded bone always atrophies.
Other factors that cause bone loss include e.g. trauma, inflammation within the gums and bone caused by bacterial plaque (periodontitis).
