Ultra-low frequency-transcutaneous electric nerve stimulation for functional border molding and cameo surface recording for enhanced complete denture success: A novel approach

Ultra-low frequency transcutaneous electric nerve stimulation (ULF-TENS) is one of the therapeutic devices used for relaxation of orofacial musculature by the use of low frequency, low current stimulation of the certain branches of trigeminal and facial nerve. Complete denture fabrication is the most widely used modality for rehabilitation of completely edentulous maxillary and mandibular arches. Numerous efforts and techniques have been introduced to improve retention and stability of prosthesis, in order to improve form, function, esthetics, phonetics, and health of the patient. These include modifications in impression making and cameo surface recording to improve the adaptation of the prosthesis. Accurate tracing of functional borders during border molding and recording cameo surface of the prosthesis using ULF-TENS in patients with poor neuromuscular incoordination can play an important role in improving the stability and enhance the performance of the masticatory system. This clinical report describes recording of border molding and cameo surface using ULF-TENS in a completely edentulous patient, resulting in enhanced adaptation with adjacent stomatognathic system.
