Two-piece dental zirconia implants in the posterior region
31 October 2022
|This study aimed at evaluating the clinical performance of two-piece zirconia implants in the posterior jaws over 9 years.
Sixty partially edentulous patients were treated with two-piece zirconia implants. In eight no primary stability could be achieved. Fifty-two patients received the final restoration.
|Thirty patients responded. The mean observation period was of 111.1 ± 2.2 months. One implant was lost. Data recorded from the remaining 29 implants were analysed.
PI (Plaque Index) values increased overtime. Mean BOP (Bleeding on Probing) and PD (Probing Depth) remained unchanged during follow-up. No additional cases of peri-implantitis were recorded over the 10 diagnosed during the first 2 years of follow-up.Conclusion: Within the limitations of the present study, a high survival rate was registered. Albeit frequent mechanical and technical complications, two-piece zirconia implants could represent a valid solution for the replacement of single teeth in the posterior jaws.
