Aim: This study was conducted to evaluate the masticatory efficiency and
perceived masticatory ability among completely edentulous patients rehabilitated with
a thermoplastic denture base Subjects and methods: This study was done in the Faculty
of Dental Medicine, Al-Azhar University. The masticatory efficiency was evaluated
in 60 completely edentulous patients. The patient received a complete thermoplastic
denture. (Vertex™ ThermoSens, Vertex-Dental B.V. Netherlands). The masticatory
efficiency and the perceived masticatory ability were evaluated at one month and after
six months of denture use. Data were collected and statistically analyzed with SPSS@
V25 to evaluate the masticatory efficiency before and after the adaptation period
for each patient to assess the association between both indices Results: Masticatory
efficiency and the perceived masticatory ability increased considerably after six months
of denture use, and they were significantly higher than values recorded one month
after prosthesis placement. Conclusions: A significant association was also observed
between masticatory efficiency and perceived masticatory ability, and both can be used
to evaluate masticatory performance among complete denture wearers.
