It has been proven that the close interaction of dental rows plays a significant role in the unity of the dentofacial system in terms of morphology and function. Their integrity is a necessary condition for the physiological functioning of the oral cavity. In the presence of dentofacial anomalies, chewing function, speech, and aesthetics are disrupted. The absence of even one tooth negatively affects not only the function of the dentofacial apparatus, the psychological state of the person, but also the entire organism as a whole. As a result of the loss of teeth, the process of chewing food is disrupted, which negatively affects digestion. The absence of teeth negatively affects the patient's articulation and communication capabilities, which cannot but affect their psycho-emotional status. Long-term presence of dental defects contributes to the distal displacement of the CNS, resulting in abnormalities in the anatomy and function of the CNS, as well as the activity of the maxillofacial nerve apparatus. Total adentia leads to significant changes in the facial skeleton.
