Designing and Fabricating Implant Prosthesis For a Single Missing Tooth

AbstractImplant supported single tooth restorations have become a predictable and widely accepted treatment option for the replacement of missing teeth, offering improved functional, biological, and esthetic outcomes compared with conventional fixed dental prostheses. Unlike traditional restorations, implant supported crowns preserve adjacent tooth structure and help maintain periimplant bone and soft tissue architecture, contributing to long-term stability and patient satisfaction.The success of these restorations depends not only on accurate implant placement but also on precise prosthetic planning and meticulous laboratory procedures. This article reviews the design and laboratory fabrication processes involved in implant prostheses for single tooth replacement. It discusses the three principal restoration types: cement retained crowns, screw retained crowns, and screw cement retained prostheses. Both conventional and digital workflows are described, including implant impression procedures, master cast fabrication, abutment selection or customization, and definitive crown fabrication. The role of different abutment systems such as stock titanium abutments, UCLA abutments, and CAD-CAM milled customized abutments is also highlighted.Advances in digital dentistry, including intraoral scanning and CAD–CAM technology, have enhanced the precision, efficiency, and reproducibility of implant prosthesis fabrication while improving communication between clinicians and dental laboratories. A well coordinated clinical and laboratory workflow is essential to achieve accurate fit, optimal emergence profile, esthetic integration, and long-term success of single tooth implant restorations.
