The patients were recruited between 16/11/2009 and 18/12/2012. Theclinicalprocedurewasperformedaccordingtothe manufacturer's guidelines. Depending on the bone density, a wider final drill was used to prevent over- compression of the bone. Both clinicians saw the pa- tients again after 3 months, 6 months and every year after that, unless check-ups were performed by the colleague who referred the patient to them. For the calculation of the implants' cumulative survival rate, the patients who did not have any check-ups were contactedbyphonetoverifytheproperfunctioningof the implants. Panoramic images or preferably intra- oral X-rays (using the long-cone, parallel technique) were made at the time of placement, at the time of loading and every year after that. Two independent clinicalresearchers(J.MerhebandW.-F.Simons)eval- uated the X-rays. An extra analysis was performed in caseswheretherewasadifference≥1mm. _Results The GC Aadva implant is made from grade V tita- nium and is cylindrical in shape, slightly tapered to- wards the apex to improve its self-tapping character- istics.Theneckoftheimplant(1.8to2.5mmwide)has micro-threads.Moreapicallythethreadsarelargerto- wards the apex, with a spacing of 1 mm.
