Clinical procedure for stabilizing and connecting O-ring attachments to a mandibular implant overdenture.

Conventional overdentures can be made with or without attachments, whereas implant-supported overdentures require bar or stud type attachments. Accurate placement of the attachments in the overdenture is critical for the success of the prosthesis and implants. An improved procedure is presented for stabilizing the existing denture with vinyl polysiloxane impression material during the clinical incorporation of stud attachments to the implant-supported overdenture.
