the aim of this study is to assess the difference between patient specific root analog implant and conventional root form implant in terms of implant stability. Materials and methods: 24 males patients with badly decayed non-restorable anterior tooth were treated with immediate implant placement. Patients were randomly assigned to one of two groups. They were either treated by placing milled titanium immediate root analogue implant or placing conventional root form implant to replace single tooth in anterior maxillary area. Implant stability was measured using periotest for both approaches at the day of surgery then after 3 and 6 months later. Results: after 6 months there was no statistical difference in implant stability on comparing Root Analogue implant (RAI) and Conventional root form. However, there was statistically significant difference between the stability at implant placement and after 3 and 6 months in both groups. Conclusion: Replacing badly decayed teeth with a Root Analogue implant can be used as an alternative to conventional immediate root form implant.
