CAD/CAM and Telescopic Technology: Design Options for Implant-Supported Overdentures
Bergler, Michael / Holst, Stefan / Blatz, Markus B. / Eitner, Stephan / Wichmann, Manfred
There are many options with respect to materials, construction methods, and design concepts for the technical implementation of implant-supported dental prostheses. Different methods of anchorage can be used to attach removable superstructures to implants. Telescopic crowns make it possible to fabricate inexpensive superstructures with precise and passive fit. Computer-aided design/computer-assisted manufacture (CAD/CAM) technology allows copings to be fabricated from materials such as zirconia or titanium. Moreover, CAD/CAM crown copings can serve as a base for fabricating customized ceramic replacement teeth. Different veneering techniques, such as pressed-on ceramics for zirconia cores, ensure a fast and economic work process. With the use of electroforming it is possible to manufacture highly precise secondary structures that ensure passive seating of the prosthesis in a stable position. This article demonstrates a restorative treatment option using current techniques with the aim of rehabilitation with an esthetic and functional implant- supported removable denture.
