Abstract

---

Introduction: The precise reproduction of the abutment (implant) provides clinician with crucial clinical information of the relative position and orientation of the implant to other implants, teeth and soft tissue that allow them to fabricate exact- fitting, bio-integrated restoration. For that it is necessary to expose, access & isolate the implant region, especially when cement retained implant prosthesis are in consideration, where conventional crown and bridge impression and optical impression technique is used. Material and Method: Patient who accepted to participate were chosen for the study. Coincidentally all 15 patients were female. They were explained the purpose and methodology, agreed for periodic follow up at the interval of one month after placement of healing abutment and 7 days after using the retraction cord. Conclusion: The conclusions that were drawn from this study are: Both materials showed clinically and statistically significant amount of vertical soft tissue displacement. Among the both soft tissue displacement agents, nonimpregnated retraction cord showed the more vertical soft tissue displacement than Expasyl Paste. But, the amount of retraction offered by this paste is limited with extremely subgingival margins. But the advantages with Expasyl paste over the retraction cord were its ease of application, painless, quick, and without agony to the patient.
