Channel retention for fixed implant superstructures: A clinical report

摘要

This clinical report describes the treatment of a patient with anatomic and biomechanical problems that made retrievability of an implant-supported prosthesis a design priority. During treatment, the patient was found to be intolerant of local anesthesia, prompting an alternative retrievable design from the screw-retained interim restoration. A channel retention technique for fixed implant superstructures is presented.
