The impact of implant treatment on oral health related quality of life in a private dental practice: a prospective cohort study.

Background: Very few studies on the impact of implant therapy on Oral Health Related Quality of Life (OHRQoL) in partially edentulous patients have been published.

Aim: This study aimed at analysing the improvement of OHRQoL of patients who underwent dental implant treatment using the "functional", "psychosocial" and "pain and discomfort" categories of the Geriatric Oral Health Assessment Index (GOHAI).

Methods: Within a prospective cohort of patients rehabilitated with Straumann dental implants, the OHRQoL of 176 patients (104 women and 72 men) was assessed using the GOHAI questionnaire, at two different times, before and after implant placement.
