As edentulousness increases, there is more lingual positioning of the neutral zone at the molar region of both sides of the arch. At the premolar region, there is no change in position of the neutral zone; it remains constant as resorption of the alveolar ridge is directly under the buttress. In the anterior region, there is more labial positioning of the neutral zone as edentulousness increases.</p><p><strong>Conclusions: </strong>This technique proves itself to be an easy and inexpensive way to determine the relationship between the crest of alveolar ridge and neutral zone.
