Application of dental implant has been expanding from single missing cases to completely edentulous cases. However, some researchers pointed out conventional oral rehabilitation modalities, e.g., full denture, could substantially promote the quality of life (QOL). There was a question as to why the implant rehabilitation is necessary in some cases and whether the implants can improve the patient's QOL has not been sufficiently examined. The superiority to conventional complete denture is still unknown. In this study, QOL levels between two groups of subjects, 1) bone-anchored fixed implant denture group (n=6) and 2) conventional complete denture group (n=60), were compared. A questionnaire was developed on the basis of a well-known QOL questionnaire (OHP) and the reliability level was confirmed in each subscale (mean kappa value=0.77) prior to the experiment. This questionnaire consisted of three categories of questions, QOL (12 items), patient's satisfaction (3 items), and oral handicap levels before and after therapy (5 items:food chewing, appearance, speech, comfort, and pain).<br/> The questionnaire was sent to all patients in the two groups after treatment and from the responses, the age, sex, and conditions of the opposing tooth in the two groups were extensively matched. Finally, 6 implants patients (mean age:57.7±11.3 years) and 24 conventional complete denture wearers (mean age: 62.0±5.6 years) were recruited.There was no difference in the general QOL scores between the two groups, while the implant denture group showed a higher satisfaction level with their oral condition and their daily activity than the conventional complete denture group. On the other hand, the oral handicap level before treatment tended to be higher in the implant group than complete denture group. However, the levels were improved by the treatment, so the oral handicap level regarding chewing, appearance, and pain was significantly less in the implant denture group after rehabilitation. Based on these findings, it was concluded that the dental implant patient group in this study suffered more from the oral condition before treatment. However, their satisfaction level with the bone anchored rehabilitation was higher than that of the conventional complete denture group.
