Patient satisfaction with two designs of implant supported removable overdentures; ball attachment and magnets.

Objective: The aim of this study was to compare ball and magnet attachments within implant-supported mandibular overdentures (ISMOD) using patient centred outcome measures. Our a priori hypothesis was that there is no difference in patient satisfaction between the two attachment types.

Material And Methods: In this within-subject crossover randomised clinical trial, edentulous patients were recruited to the study and completed a denture satisfaction questionnaire before having two implants placed in the intraforaminal region of the mandible.
