Editorial note: Reprinted by permis- sion of Inclusive™ magazine, ©2016, Glidewell Laboratories. Dr. Jack A. Hahn earned his DDS from The Ohio State Uni- versity College of Dentistry and com- pleted postgraduate coursework at Boston University, New York University, the University of Michigan and the University of Kentucky. A pioneer in the field of implant dentistry, Hahn has been placing and restoring implants for more than 45 years. Hahn developed the Nobel-Replace dental implant system for Nobel Biocare and oversaw the design of the Hahn Tapered Implant. Recipient of the Aaron Gershkoff Lifetime Achieve- ment Award in implant dentistry and the Venue and LEAD magazine Healthcare Leadership Award, Hahn was honored with the Lifetime Achievement Award from the American Academy of Implant Dentistry in June 2015. Hahn is also edi- tor-in-chief and clinical editor of Inclusive magazine. He lectures to dentists around the world and maintains a private prac- tice in Cincinnati, Ohio.

I told them, “We need a tapered im- plant that doctors can easily place, stays right where you want it, and gets maximum primary stability.” They looked at my drawings, and their team of engineers helped me fine-tune the design until we got the thread pattern just right. We ended up with an implant that can be directed against the palatal bone, avoids the facial plate and fits within tight anatomical spaces. The Hahn Tapered Implant includes a 1 mm- machined collar. Because both hard and soft tissue is stable around a ma- chined collar, this design affords doc- tors the flexibility in crestal position- ing they need to meet the esthetic demands of each case. We designed the implant with a conical connec- tion to ensure a strong, stable seal. The prosthetic connection also facili- tates platform switching, which has been shown in numerous studies to preserve bone and gingival tissue around the implant-abutment inter- face.2–4 To ensure an optimal restora- tive outcome, the Hahn Tapered Implant System features contoured healing abutments and matching transfer copings. Since we launched the Hahn Tapered Implant in 2015 and began work- ing with experienced practitioners, we’ve received nothing but positive feedback. The comment that I hear repeatedly is: “Jack, I love your im- plant.” Looking back at this patient’s radiograph, I know that we’ve come a long way with implant design. Conclusion The various implants I’ve designed and placed in this patient through- out the years demonstrate that suc- cess is highly predictable as long as we adhere to the proper diagnostic, surgical and restorative principles. At the same time, advancements in implant design have simplified sur- gery and made it easier to establish the implant positioning and stability Fig. 7: Dr. Hahn in his Cincinnati office holding the patent for the original tapered im- plant design. The patient’s root-canal-treated mandibular canine needed to be separated from the posterior bridge connected to the patient’s JAH 2000 blade implant. Because both of the Hahn Tapered Implants achieved excellent initial stability, immediate provisional crowns were delivered. The patient’s other implants have performed well, but required more work to get the outcome I wanted. With the Hahn Tapered Implant, there are fewer steps. The Hahn Tapered Implant’s ability to remain engaged with the palatal bone and attain maximum primary stability is the result of its deep, sharp threads, which I consider the im- plant’s most important design inno- vation. By the time I began develop- ing the Hahn Tapered Implant, I had concluded that the thread patterns of the previous implant systems I designed weren’t aggressive enough. As a result, the implant could wan- der toward the thin cortical bone of the facial plate during placement. Other implant systems on the mar- ket that had a sharper-cutting thread design were too aggressive and could cause microfractures in narrow bone or ridges. So I designed a new tapered im- plant, including threads that were just aggressive enough, and brought it to Glidewell Laboratories.
