Fundamental model for the classification of topography of the human mandibular canal with bone atrophy caused by loss of the masticatory teeth

Abstract

When teeth are lost, not only the collar part of the jaw undergo pronounced pathological changes, but also the neurovascular roots of the same name with reflection on the central neurovascular bundle in the mandibular canal, which should provide nutrition and innervation of its toothless segments, and is also an ethio-pathogenetic factor of irreversible bone atrophy (Liu M, Sun Y, Zhang Q, 2018; Oshurko AP, Oliinyk IYu, Kuzniak NB, 2021).
