Abstract

Purpose: This study was directed to evaluate the electromyographic activity(EMG) of patients with rapid prototyped (RP) complete denture. Subjects andmethods: A total of ten completely edentulous subjects aged between 45-50 years wereselected following specific inclusion criteria from the outpatient clinic of RemovableProsthodontics Department, Faculty of Dental Medicine for Girls, AL-Azhar University.All Patients had received two complete dentures; one constructed by rapid prototypedtechnology and the other constructed by conventional heat compressed method.Patients were classified into two groups, five patients in each. First Group received theRP complete denture first then the conventional complete denture (CCD) while, secondgroup received the (CCD) first then RP complete denture. All patients were instructedto wear their denture for equal periods and recalled after 1- week, 1- month and 3-months to measure the (EMG). After an interval of 2- weeks, as a wash out period,patients received their other dentures. Results: Conventional complete denture showedsignificant higher EMG than RP denture at different testing periods and with differenttested foods. Also, the EMG of both masseter and anterior temporalis muscles improvedwith time for each tested denture. Conclusion: Conventional complete dentures still thebest rehabilitation choice for completely edentulous patients. Rapid prototyped denturecould be suitable alternative for completely edentulous patients.
