Periodontal Evaluation of One-Piece and Two-Piece Single Implant Loaded in Esthetic Zone

Abstract

Background: Soft tissue around dental implant is an important anatomical feature contributing to the long-term implant success and esthetics, different factors may influence the soft tissue-implant interface. The purposes of the current study were to evaluate the soft tissue profile around one-piece and two-piece implants loaded in esthetic zone. Method: Totally thirty patients who had single missing tooth in premaxillary region were included in the study. Fifteenth patients’ group-A were assigned to immediate loading one-piece implant and fifteen patients’ group-B were assigned to early loading two-piece implant protocol. Flapless approach was performed for both groups. In group-A, implants were loaded immediately with a temporary crown within 48h, while group-B, were loaded after two months following conventional impression for metal ceramic crown. Clinical outcomes were evaluated after two and six months in terms of success rate, papillary index, plaque index and width of keratinized mucosa. Results: The success rate in group-A found to be 80%, which was lower than the success rate in group-B (100%). On comparison, there was no statistically significant difference in success rate between the two study groups. There was no statistically significant difference between both groups over time in clinical parameters like plaque index, width of keratinized gingiva and papillary index. Conclusion: The results of this study indicated that using either immediately loading one-piece implants or early loaded two-piece implants protocol demonstrated the same enhancements of implant esthetics
