ABSTRACT

Purpose- Immediate implantation has provided the opportunity to achieve better and faster functional results. The placement of implant immediately not only prevents the collapse of the socket by reducing the crestal bone loss, but also enhances the soft tissue esthetics. The placement of dental implant into fresh extraction sockets was introduced in 1970 and is a well-established treatment option for replacing missing teeth, allowing the restoration of masticatory function, speech, and esthetics (Schwartz et al). Aims and objective – 1. Evaluate the crestal bone loss 6 months after surgery with the help of IOPAR, and CBCT.2.Assessment of the Peri implant health by measuring the probing pocket depth, gingival index, plaque index at loading time (3 month after surgery) and 6month aftersurgery. 3.To determine the esthetic outcome around immediate implant by using Pink estheticscore. Materials and methods - This clinical study was conducted on patients, requiring implant placement in both the jaws and was operated under local anaesthesia in the Department of Oral & Maxillofacial Surgery of Guru Nanak Institute of Dental Sciences and Research, Kolkata, West Bengal. The operator and other factors remained same in this study. After having an ethical committee clearance, eight patients were selected according to the previously laid down inclusion and exclusion criteria. Total twelve non-restored teeth selected and twelve implants were placed immediately after teeth extraction, as few patients received multiple implants within esthetic region. Prior to surgery, patients were randomized single blindly into one of the two treatment groups. Group A- received Immediate implant along with xenograft alone. Group B- received Immediate implant along with xenograft and platelet rich fibrin. All the implants were placed according to the manufacturer’s protocol and gingival former was placed at same time. A healing period of 3rd months was maintained in each case. At the end of 3rd month the loading was done. The marginal bone level was checked with CBCT and IOPA grid x-ray, right after implant placement and 6 months post surgery. All the implants were also clinically evaluated for plaque index, gingival index and pink esthetic score and mobility. Results- All the results of this study were statistically insignificant (p>0.05). Conclusion- Platelet rich fibrin could not be shown any additional effect on hard tissue and soft tissue around implants.
