Abstract

 
Purpose: This study was directed to evaluate the electromyographic activity
(EMG) of patients with rapid prototyped (RP) complete denture. Subjects and
methods: A total of ten completely edentulous subjects aged between 45-50 years were
selected following specific inclusion criteria from the outpatient clinic of Removable
Prosthodontics Department, Faculty of Dental Medicine for Girls, AL-Azhar University.
All Patients had received two complete dentures; one constructed by rapid prototyped
technology and the other constructed by conventional heat compressed method.
Patients were classified into two groups, five patients in each. First Group received the
RP complete denture first then the conventional complete denture (CCD) while, second
group received the (CCD) first then RP complete denture. All patients were instructed
to 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 showed
significant higher EMG than RP denture at different testing periods and with different
tested foods. Also, the EMG of both masseter and anterior temporalis muscles improved
with time for each tested denture. Conclusion: Conventional complete dentures still the
best rehabilitation choice for completely edentulous patients. Rapid prototyped denture
could be suitable alternative for completely edentulous patients.
