The aim of this study was to report on our experience and outcomes with Certain Prevail Implants and immediate loading via the Diem System after a 16-month follow-up period. Over a 16-month period, 105 (14 maxilla, 91 mandible) expanded-platform implants were placed in 18 patients (15 females, 3 males; 55.97 +/-7.25 SD years). Resonance frecuency analysis (RFA) was measured on the day of placement and at 3, 12 and 16 months. All prostheses were screw mounted on IOL DIEM standard abutments. The follow-up time varied between 3 up to 16 months. One implant (0.9%) failed during final prothetic placement (3 months).The RFA (ISQ) measurements at 16 months evalution for 4 mm- and 5 mm diameter implants were: 76.13 +/- 5.0 SD and 76 +/-7.7 SD respectively. The RFA data related to mandible and maxilla, the day 0 mean was 76.47 +/- 4.75 SD and 70.13 +/- 1.35 SD, at 3 months 70.53 +/- 4.0 SD and 66.07 +/-2.9 SD, at 12 months 68.23+/- 3.6 SD and 66.40 +/-2.7 SD and 16 months 68.23+/- 3.6 SD and 66.60 +/- 2.5 SD respectively. The crestal bone resorption was 0.6 mm at 16 months in platform switching implants. The cumulative implant survival rate during the follow-up period was 99.1% Immediate loading on IOL Diem abutments is a reliable and effective technique for edentulous patients in the maxilla and mandible.
