AO commences new series on research
Each year, more than 2,000 dental colleagues from around the globe converge at AO’s Annual Meeting. Among other benefits of attending the premier dental conference of the year, participants have access to an immense wealth of the latest research presented by hundreds of clinicians, researchers, residents and their faculty.
2017 was no exception, with nearly 260 abstracts submitted and more than 200 e-posters on display. Out of these, a very elite group of six researchers were recognized and the top posters were selected and received honors by a committee of their peers for their outstanding contributions to the field of implant dentistry.
To help share more of the research that is presented every year, AO is kicking off a brand new CONNECT series, which begins with one of 2017’s top research award winners.
Justin Kang, DMD, MPH, 2017 1st Place e-poster winner
“The 2017 AO poster presentation was an incredible educational experience. It was not only an opportunity to learn about new and exciting research conducted by other participants, but also to discuss and receive feedback from reviewers who have expertise as researchers and clinicians,” said Dr. Kang. “I would like to sincerely thank Dr. Daewon Haam and Dr. Dennis Tarnow for their guidance and mentorship throughout the entire process.”
Dr. Kang’s presentation was on how Alveolar ridge resorption in vertical and horizontal dimensions is an inevitable biologic process following tooth loss. He said promotion of early bone formation to counteract alveolar dimensional loss and to preserve the volume and shape of the alveolar process is critical to the delivery of predictable esthetic and functional implant therapy.
The primary objective of Dr. Kang’s study was to evaluate whether early bone formation can be promoted via application of atelocollagen in a bioabsorbable polylactide-polyglycolide carrier in comparison to healing by natural clot.
All experiments were approved by the Institutional Animal Care and Use Committee (IACUC) at Columbia University. Mandibular 2P2, 3P3, 4P4 and 1M1 were extracted in four male mongrel dogs. Each hemi-mandible was then randomly assigned by method of healing: natural clot, 3% aqueous atelocollagen, atelocollagen plug type, and commercially available collagen plug.
Extraction sockets healed for six weeks. A bone core was taken from each extraction socket using a trephine bur, and evaluated for bone and tissue volume, and % mineralized bone, woven bone and total bone.
Atelocollagen plug type resulted in a significantly greater increase in both woven bone and total bone in comparison to healing by natural clot. This result was further supported by non-significant difference in total bone between atelocollagen plug type and commercially available collagen plug.
“To the best of our knowledge, this is the first study of its kind to observe early socket healing using atelocollagen in the dog model. This study demonstrates the efficacy of atelocollagen in a PG-PL carrier in promoting early bone formation in healing extraction. Further research is required to determine the exact mechanism of the effects of atelocollagen in hard and soft tissue healing, as well as its application in conjunction with bone substitute materials,” concluded Dr. Kang.
