5 SCIENCE / CLINICAL RESEARCH preliminary results confirm the outcomes of the on-going multicenter study per- formed on CAMLOG ® Implants with and without Platform Switching (Guerra et al., 2014) [3], which demonstrated an excel- lent maintenance of the crestal bone level with a bone-level change at one-year post loading of only 0.08 mm (with Platform Switching). Conclusion The solid documentation of the CAMLOG ® and CONELOG ® Implant Systems is based on independently collected data or on scientific evidence sponsored by the company. This is an important contribution to CAMLOG’s success story. More than 11,000 implants with a Promote ® surface present follow-up data of at least 5 years. The use of Platform Switching (Rocha et al., 2012, 2014) [9,10] and the stability of the implant-abutment connection are key fac- tors contributing to the good integration of CONELOG ® Implants. 4th Research Award – Deadline for registration November 30, 2015 The CAMLOG Foundation plays an im- portant role in the promotion of research of young talented scientist. The competi- tion for the 4th CAMLOG Foundation Research Award is open. You can find more information on our website at www.camlogfoundation.org .
