Abstract

The purpose of this multicentre observational study was to determine patient satisfaction with either conventional dentures or mandibular 2-implant overdentures in a 'real world' setting. Two hundred and three edentulous patients (mean age 68·8 ± 10·4 years) were recruited at eight centres located in North America, South America and Europe. The patients were provided with new mandibular conventional dentures or implant overdentures supported by two implants and ball attachments. At baseline and at 6 months post-treatment, they rated their satisfaction with their mandibular prostheses on 100-mm visual analogue scale questionnaires. One hundred and two (50·2%) participants had valid baseline and 6-month satisfaction data. Although both groups reported improvements, the implant overdenture group reported significantly higher ratings of overall satisfaction, comfort, stability, ability to speak and ability to chew. These results suggest that edentulous patients who choose mandibular implant overdentures have significantly greater improvements in satisfaction, despite their relatively higher cost, than those who choose new conventional dentures.
