title: Completely Digital Two-Visit Immediately Loaded Implants: Proof of Concept.
abstract: Implant dentistry has become a common treatment alternative, yet only a small percentage of patients missing teeth are receiving its benefits. Significant limitations are the small percent of practitioners placing implants due to the long learning curve, as well as the time commitment on the part of the patient. This proof of concept demonstrates clinical implant treatment requiring years of manual skill development on the part of the surgeon, restorative dentist, and technician can be accomplished in 2 visits, completely digitally, without the need for conventional impressions, laboratory procedures, and advanced manual skills. This technique results in reduced learning curve and treatment time. The first visit consists of consultation, diagnosis, CT and optical surface scans of the implant site to include: soft tissue, adjacent teeth, and opposing arch. This digital information is imported and interactively reconstructed in a 3-D open format implant planning software. The implant and restoration are now precisely planned into the optimal bone position with the ideal emergence profile for biologically and esthetically designed restoration. This information is then electronically forwarded to a production facility, where all necessary models are digitally printed and the immediate crown is digitally milled. On the second visit, the patient returns for guided implant insertion and immediate restoration. As digital procedures are refined, many more dental professionals will become involved in providing implant therapy earlier in their careers. This promises to result in reduced costs, making implants available to millions more patients who could benefit from them.
