Purpose: The purpose of the present study was to determine the marginal bone loss and analyze peri-implant soft tissue using PES around single immediate loading implant with different superstructure materials (PMMA, zirconia, PEEK). Materials& Methods: A single center blind and parallel group study applied on 17 patients (17 implants) in the age group 25-40 years with a thick gingival biotype and intact buccal bone wall of healed extracted upper centrals or upper 1st premolar. All patients were receiving delayed implantation with immediate non-occlusal loading utilizing different superstructure material. Group (A) control: PMMA crowns for 6monthes followed by final zirconia crowns, group (B) Zirconia crowns and group (C) PEEK crowns. Patients were recalled for follow-up and PES was analyzed at 3, 6, and 12 months while marginal bone loss was determined at 6 and 12 months. Results: The results of pink esthetic score (PES) and the marginal bone loss (mm) showed no significant difference between different groups at different follow-up intervals (P>0.05) while marginal bone loss for all groups recorded at 12 months a significantly higher mean bone loss value at 12 months than 6 months (P>0.05), Conclusion: within the limitation of the current study, immediate loaded implants with zirconium and PEEK superstructure had a minor role on enhancing peri-implant soft tissue esthetics and decreasing the marginal bone loss |
