Abstract
Question: Does use of dental implants in edentulous patients result in better quality of life compared with conventional treatment?
Objective To compare the effect on health-related quality of life of two treatments for edentulism, conventional mandibular dentures and implant-supported prostheses.
Design A randomised controlled trial in a hospital setting.
Intervention A total of 102 people were assigned randomly into either implant or conventional treatment groups. The implant group received two implants in the lower canine region connected by a short bar. Either a conventional denture or over denture was provided in the lower jaw with conventional upper denture. Patients were analysed using the intent-to-treat principle, with patients who withdrew being allocated their pretreatment OHIP scores
Outcome measures An oral health impact profile (OHIP) was conducted at the initial appointment and 2 months after the fitting of the prosthesis.
Results See Table 1.
Conclusions Using a validated standard assessment tool, this trial suggests that patients who had implant treatment experienced more improvements in perceived oral health than patients having conventional treatment.
