Innovative Approach Utilizing Combined Swallowing and Phonetic Method to Establish Neutral Zone in a Severely Resorbed Complete Edentulous Lower Arch: A Case Report.

Abstract

Retention in lower complete denture prosthesis, most of the time is a rare achievement for the dental surgeons due to the configuration of the lower denture bearing surface and its associated tissues. Neutral zone technique is a firmly established method to achieve stability of the prosthesis in situations with difficulty in achieving retention. Even then, severely resorbed ridges often pose challenges with conventional neutral zone technique. This case report focuses on a unique technique in achieving stability of a complete denture prosthesis in Atwood’s class IV and class V ridge resorption by using the advantageous effects of combined swallowing and phonetic technique. Imprint of the potential dead space area at the most non-disturbed zone, where soft tissues oral musculature and tongue produces minimal deflective and dislodging force on the prosthesis has been the goal of the technique used in this particular case report.
