The objective of this study was to determine the effects of using intraoral prosthesis on women's body image and sexual quality of life. This study was performed as a crosssectional study. The study sample included 60 women who presented to a prosthodontics department in Turkey. The study data were collected with the Personal Information Form, The Multidimensional Body-Self Relations Questionnaire (MBSRQ) and Sexual Quality of Life Questionnaire-Female (SQLQ-F). After filling in the forms, they were examined by a dentist. Prostheses were made in approximately 15 days and placed (inserted) into the patient's mouth. The SQLQ-F and MBSRQ were readministered to the women 6 months after they started with their prostheses. The participants' sexual quality of life changed for the better after they used fixed or removable prostheses. While perceived body image of the participants using fixed prostheses changed positively, there was no change in the body image perception of the participants using removable prostheses. The mean scores obtained from the Appearance Evaluation and the Body-Areas Satisfaction subscales by the participants using fixed and removable prostheses at baseline significantly increased at the sixth-month follow-up.
