The client has requested a fixed bar to be designed for the maxillary arch on 6 implants. The client has also requested the design to incorporate individual crowns which will be permanently bonded to the framework.
Based on the requirements a fixed crown bar was chosen. The characteristics of this arrangement allow for a profile that will incorporate individual crowns. These crowns are intended to be bonded to the framework whilst still allowing access to the retaining screws.
The profile of the bar also incorporates polished lingual and intaglio surfaces so that any lingual bulk can be kept to a minimum, this profile also aids in longer term maintenance and cleanability between the appliance and soft tissues.
