Satisfaction of patients with mandibular implant-supported overdentures using a generalized estimating equation model: A prospective study :

Abstract

Aims: To assess the effect of history of conventional denture use, number of implants, age, gender, and time passed since delivery (1 and 3 months) on satisfaction of patients with mandibular implant-supported overdentures. Materials and Methods: This prospective study was conducted on 54 eligible edentulous patients (48-74 years, 30 males and 24 females). After obtaining written informed consent and ethical approval, the patients filled out a questionnaire regarding their satisfaction level with the overdenture. Data were analyzed by the generalized estimating equation (GEE) model at 5% level of significance. Results: History of denture use (P=0.232) and number of implants (P=0.609) had no significant effect on the overall satisfaction of patients. The overall satisfaction was not significantly different between males and females (P=0.415). The effect of time passed since delivery and age on satisfaction level was significant, such that the overall percentage of satisfaction was higher at 3 months after delivery (P<0.001) and in older individuals (P=0.040). Conclusion: The satisfaction level of patients with mandibular implant-supported overdentures depended on the time passed since delivery and age of patients; number of implants (2 or 3) and history of denture use had no significant effect on patient satisfaction with the overdenture.
