Advancements in digital dentistry have streamlined implant therapy to the point where restorations can be produced more quickly and accurately than ever before. Custom prosthetic components designed and fabricated with CAD/CAM technology facilitate an ideal emergence profile for implant restorations and can typically be delivered with minimal or no adjustments. The digital workflow initiated by intraoral scanning produces time and cost savings while improving the precision and quality of care. In this presentation, Dr. Timothy Kosinski outlines the advantages of CAD-designed custom abutments produced from digital impressions. Several cases are reviewed that illustrate the benefits of this “model-less” approach to implant dentistry. Topics include:
- Facilitating restorative-driven treatment with intraoral scanning and CAD/CAM technology
- Improving turnaround times and esthetic outcomes with digital technology
- The advantages of digital impressions vs. conventional impressions
- The step-by-step restorative workflow initiated by intraoral scanning
- Utilizing digital impressions and CAD/CAM technology to visualize prosthetic outcomes
- Optimizing soft-tissue contours and emergence profiles with custom abutments
- Proper seating of custom abutments using acrylic positioning jigs
- Application of CAD/CAM technology in the design and production of restorations
The combination of intraoral scanning and CAD/CAM technology unlocks a streamlined workflow that results in well-fitting restorations, controlled costs and less time between appointments. Addressing the emerging emphasis on esthetic outcomes in implant therapy, CAD-produced custom abutments maximize gingival contours and margins while allowing doctors an opportunity to evaluate the digital design prior to fabrication of the restoration. By submitting the final impression for the custom abutment and final crown via intraoral scanner, doctors are able to deliver exceptionally accurate restorations and maximize clinical efficiency.
CAUTION: When viewing the techniques, procedures, theories and materials that are presented, you must make your own decisions about specific treatment for patients and exercise personal professional judgment regarding the need for further clinical testing or education and your own clinical expertise before trying to implement new procedures.
