This prospective cohort study1 evaluated the clinical outcomes of NobelActive implants in the maxillary esthetic zone.
15 patients received 15 narrow or regular platform implants in fresh extraction sites which were immediately provisionalized. As a definitive restoration, all patients received a crown on either Procera Esthetic Abutments (Zirconia; n=13) or Esthetic Abutments (titanium; n=2) within six months.
At two-year follow-up, success and cumulative survival rates were 100%, and marginal bone level was changed to –1.4±1.89mm (from- 2.34±1.98mm at implant insertion), resulting in 0.83 mm of bone gain. Soft tissue assessment at two years showed improved mean Jemt Papilla scores (2.1 at insertion to 2.55), low bleeding on probing (9%) and no plaque accumulation.
The authors concluded that NobelActive can be used effectively in extraction sites in the maxillary esthetic zone.
