The Role of CAD/CAM in Contemporary Fixed and Removable Beam and Bar Prostheses
Reliable single crowns and two to four unit bridgework have been made using implant-supported substructures or copings made by CAD/CAM for more than ten years, with high success rates.
However when all teeth in an arch are missing the diagnostic and aesthetic issues become much more complicated and the prosthodontic options increase. Larger fixed and removable prostheses are now possible with substructures made from various metals, zirconia and resin/fibre materials, all of which can all be milled using CAD/CAM. These substructures need to be compatible with porcelain, acrylic or resin veneering materials and need to have a good appearance and a good life expectancy. Several designs for the fixed full arch maxillary prosthesis - the most complicated dental implant restoration - will be discussed as well as the need for its easy removal when required. Not all CAD/CAM is the same. Evidence supporting various techniques and combinations of materials will be presented. A patient’s expectations may rise with the cost of the prosthesis and the amount of chair time required. Patient satisfaction is at the core of GDC guidance protocols and this presentation will consider the various issues that affect prosthetic success.
Oral hygiene issues will also be discussed, as will parafunctional patients and ‘Teeth in a Day’ full arch protocols. This presentation will also briefly look at the traditional concepts behind the traditional implant-supported overdenture, and will give some evidence-based recommendations regarding modern retentive elements.
