Laboratory processing of housing-retained attachments for implant-supported overdentures.
The use of a metal housing-retained attachment for implant-supported overdentures: (1) facilitates easy removal and replacement of a matrix attachment during routine recall examinations, and (2) ensures correct alignment and retention to the implant-supported bar assembly. This article describes a laboratory technique for processing the bar assembly (without allowing acrylic resin to seep under it) with the master cast invested in the metal flask. The technique ensures a precise fit of retentive attachments at the delivery of the overdenture to the patient.
