| Abstract | ||
| Objective: This study aimed at comparing clinically and radiographically the marginal bone loss and soft tissue response to titanium dental implants with Zirconia collar versus titanium implants with titanium collar placed in esthetic zone. Subjects and methods: Twenty non-smoking patients (ranging from 22 to 43 years) participated in this randomized clinical study. Patients were randomly assigned into one of 2 groups (10 patients each): patients who received two-piece, one-stage, titanium implants with zirconia collar (Periosave, Z1 Conic, TBR Implants Group, France) will processed as a treatment group (Group I), patients who received two-piece, one-stage, titanium implants with titanium collar will processed as a control group (Group II). Clinical and radiographic parameters including Modified plaque index, Modified bleeding index, Crestal bone loss were reassessed at 9 months after surgery. Results: Specifically, marginal peri-implant hard tissue changes that occurred using an implant system with zirconium collar (Group I), in comparison with another types with titanium collar (Group II) were minimal and with no significant difference during the first 9 months after implant installation. Conclusion: The use of titanium implant with transmucosal zirconium collar (Z1 TBR implant) did not show statistical significance in comparison to titanium implant with titanium collar in terms of limitation of crestal resorption usually seen after loading. | ||
