An Contemporary Techniques for Recording Severely Resorbed Mandibular Ridge: A Case Report

Resorption of mandibular ridges is a multifactorial and biomechanical disease that is chronic, progressive,
irreversible, and cumulative leading to loss of sulcular depth, vertical dimension loss, and decreased lower
facial height. Some common neurological, hormonal, and metabolic disorders affect the adaptability of
dentures, and this can be diagnosed by a trained prosthodontist with proper history-taking and clinical
examination. The denture becomes passive due to complex neuromuscular control and causes difficulties
in impression-making, mastication, and swallowing, which in turn leads to loss of retention and stability in
complete dentures. The loose and unstable lower complete denture is one of the most common problems
faced by denture patients. One of the methods used to solve this problem is the neutral zone technique.
Neutral zone technique is long being used for the management of severely resorbed mandibular ridges. The
piezography technique, a special functional approach is described in order to overcome the difficulties of the
mandibular denture. Piezography, prosthetic space recorded by pronunciation, can be used as a reference for
arrangement of artificial teeth and polishing surface of a denture.
