Abstract
Background: Implant-supported overdentures could have many benefits for patients, especially in the lower jaws. As a matter
of fact, the most common reason for prescribing mandibular overdenture is dissatisfaction of patients with mandibular dentures
usually because of a lack of retention, stability and function and speech difficulties. On the other hand, patients’ expectations of
overdenture treatments are their main disadvantage.
Objectives: The aim of this study was to evaluate the satisfaction of patients who had received mandibular implant supported
overdenture treatment with different number of implants.
Patients and Methods: This study was a descriptive cross-sectional study. Twenty-five patients with a mean age of 62.7 years who
had received mandibular implant supported overdenture treatment at the dental school of Hamadan University of Medical Sciences
were enrolled. Among these patients, six had overdentures supported by one implant, nine had overdentures supported by
two implants, two had overdentures supported by three implants, five had overdentures supported by four implants and three
had overdentures supported by five implants. The visual analogue scale (VAS) questionnaire was used to evaluate the general satisfaction,
comfort, esthetic, fitness, satisfaction of chewing and social communication, and the data was analyzed by the analysis of
variance (ANOVA) test.
Results: All patients in all five groups were satisfied with their overdentures; however there was no significant relationship between
the number of implants and fitness (P = 0.446), esthetic (P = 0.843), comfort (P = 0.805), satisfaction of chewing (P = 0.133), social
communication (P = 0.322) and general satisfaction (P = 0.493).
Conclusions: There was no difference in satisfaction level of patients who had received mandibular overdentures with different
number of implants.
