IMPLANT TRIBUNE Purpose  Scientists aimed to establish a bio- mechanical approach to directly mea- sure relative motion at the implant- abutmentinterfaceandtoquantifymicro- motion in a variety of implant-abutment combinations. Geometry of the implant- abutment interface, fabrication method of the abutment, engagement of antirota- tional features, abutment material, tight- ening torque and type of manufacturer (original, clone) were investigated. Materials and methods  Implant-abutment assemblies were fixed in a universal testing machine at a 30-degree angle. A cyclic load of 200 N (Newtons) was applied to the specimens 10 times at a cross head speed of 100 N/s while relative displacement between the implant and the abutment was quantified using extensometers. For five consecutive loading cycles per specimen, micromo- tion was recorded as a basis for statistical analysis. Comparative analysis was based on Welch tests. Results Investigated implant-abutment combina- tions produced a broad range of micromo- tion values. Researchers did not find per- fect implant shoulder geometry or perfect fabrication technique that would result in undetectable micromotion. The values for micromotion at the implant-abutment in- terface ranged from 1.52 to 94.00 µm (mi- crometers). Researchers found tightening torque significantly affected the level of micro- motion when one specific abutment type was investigated. Implant shoulder design did not reveal a significant effect in all cases. Lack of engagement of antirotational features of the implants resulted in increased micromotion, regardless of the implant system investigated. Casting onto prefabricated gold cylin- ders resulted in abutments with signifi- cantly less micromotion as compared to copy-milled stock abutments. Computer- aided design/computer-assisted manu- facture (CAD/CAM) zirconia abutments showed less micromotion than CAD/ CAM titanium abutments. Inconsistent levels of micromotion were recorded for CAD/CAM abutments coupled to propri- etary and competing implant systems. In most cases, the CAD/CAM abut- ments performed as well as stock abut- ments. Great variations in micromotion were found with clone abutments and clone implant systems.

In their own words: I attended the AO 2014 Annual Meeting as a second year graduate prosthodontic resident, and it was an enriching experi- ence. The comprehensive accumulation of lectures by specialists in the field of prosthodontics, oral surgery and peri- odontics elevated my clinical and academ- ic benchmark. I had the opportunity to present a table clinic, which gave me a chance to interact with many co-residents going through the same training as myself. It was a great edu- cational experience, and an environment in which to share new thoughts and ideas about what’s up and coming in our respec- tive fields. The AO meeting also had the perfect circumstances for me to connect with eminent members of our field, like Dr. Steve Eckert and Dr. Dennis Tarnow, and to talk about future professional goals and tips on how to achieve them. As a graduate resident, my aim was to collect maximum information for my masters thesis, and the various lectures on CBCT scanning and virtual treatment planning of implants were of immense value. The most comprehensive and up- to-date data provided on these subjects greatly helped my research. My keen in- terest being in immediate loading and virtual planning of implants, I found it very beneficial to interpret the long-term follow up of experienced professionals in this discipline. Vrinda Mohunta, BDS graduate resident advanced prosthodontic program Ohio State University, College of Dentistry I attended the AO 2014 Annual Meeting as an advanced surgical implant trainee at UCLA. It was my third time attending, and I consider it to have been the most profit- able in all aspects regarding education, ex- perience and networking. I used the meeting to make new contacts with other residents and colleagues from other programs, as well as have fun and relax at the social events with my friends. I also did an oral presentation at the meet- ing, and my advice to students and resi- dents is to attend these presentations and visit the posters. Do not be shy of asking questions and discussing them with oth- ers. AO has such an amazing environment, which makes it easy to introduce oneself and have good conversation with the most important leaders in the field. It’s a won- derful opportunity to be at the forefront of implant science around the globe. I will be attending AO’s 2015 Annual Meeting, so I can continue to learn and see my friends again!  Rodrigo G. Beltrao, DDS, PhD oral maxillofacial surgery and implant dentistry Prof. Implant Dentistry Sobracid/Imed UCLA Advanced Surgical Implant I attended the AO 2014 Annual Meet- ing as a graduate prosthodontics resident at University of Michigan. The meeting provided a great opportunity to combine learning with socializing. It was an op- portunity to exchange ideas and lay the groundwork for future collaborations, as well as meet up with old friends and make new ones. The uniqueness of this meeting is that it gives you multidisciplinary exposure to clinical advances and interventions, while also giving you an opportunity to partici- pate in social events that allow you to have fruitful dialogue about the progress being made in our field. The opportunity to meet leaders in this field is nothing less than inspiring for the new dental generation. Plus, the destina- tion gives you a chance to experience cul- tural and culinary flavors while mingling with future colleagues from around the world. I am looking forward to this year’s meeting.
