Several attachment systems for implant-supported removable dental prostheses (ISRDPs) are currently available. The bar attachment option includes cast or milled alloyed male and female parts. Replaceable slide attachments made from elastic materials can be inserted into the female part of the bar to counter loss of friction that develops due to wear. Another approach involves milling the female part from organic thermoplastic polymers. In the present case history report, an edentulous maxilla was restored with a digitally fabricated ISRDP with the female part of the bar milled from polyether ether ketone (PEEK) polymerized into a zirconia framework.

When immediately temporizing an implant, relining and cementation of the provisional can be a challenging, time-consuming, and contaminating procedure. Excess resin and cement need to be carefully removed from the fresh wound. This can be overcome by digitally backward planning the treatment with subsequent production of a surgical guide to be used by both the technician and the dentist. In this report, a patient with a fractured and hopeless central incisor and an apical radiolucency at his compromised (root-canal treated, post and core build-up) contralateral counterpart was treated using guided implant installation, immediate placement of a prefabricated screw-retained provisional, and apicoectomy. Dehiscence of the buccal plate after tooth extraction resulting in the need for hard- and soft-tissue grafting and delayed surgery did not affect the clinical outcome.
