Abstract
Purpose: The aim of the present clinical study was to display the benefits of three innovative direct attachment incorporation methods in order to prevent or minimize metal housing debonding from dentures, attachment malpositioning, and acrylic resin entrapment within attachment undercuts in implant supported mandibular overdentures.
Methods: Three innovative methods: Pre-coating of metal housings with autopolymerizing acrylic resin (AAR), fabrication of acrylic resin bars for optimal parallelism, and block-out of attachment undercuts with light-cured composite resin onto circumferential plastic spacers were applied to totally 9 patients in order to minimize the incorrect positioning of the attachment components, to prevent debonding of metal housings from the denture and the avoid entrapment of the AAR around the implant-attachment interfaces.
Results: Not any acrylic resin entrapment within implant-attachment interface was detected. The positioning of the attachments was correct. After a follow-up period of 1 year, not any debonding of metal housing was seen and all patients used their dentures without any severe complaint. Clinical and radiographic evaluations did not reveal any pathological sign.
Conclusion: It was concluded that the 3 innovative direct attachment incorporation methods used in the present study could be used as appropriate alternatives in the attachment incorporation procedures of implant-supported mandibular over-dentures.
