Brief summary
The present study is a human, prospective, parallel, randomised controlled clinical trial conducted to explore the efficacy of injectable PRF around dental implants. The trial is in accordance with the Consolidated Standards of Reporting Trials (CONSORT) criteria, 2010.
Detailed description
Ten healthy individuals satisfying the inclusion and exclusion criteria were recruited for the study. A detailed, thorough medical and dental history was obtained and each patient was subjected to comprehensive clinical and radiological examination. All patients were informed about the nature of the study, the surgical procedure involved, potential benefits and risks associated with the surgical procedure and written informed consent were obtained from all patients. All the patients were treated with immediate implants. The injectable -PRF was coated on implants as well as injected in the socket in both the maxillary and mandibular anterior region. The clinical and radiographic parameters were recorded at baseline, three months and six months postoperatively.
Interventions
BIOLOGICALI-PRF
Local anaesthesia was administered and mucoperiosteal flap was reflected. Atraumatic tooth extraction was performed. Socket was curetted to remove the granulation tissue present in the socket with the help of curettes. The socket was well irrigated with saline. Implant osteotomies wasl performed with sequential drilling with standardized drills.I-PRF was freshly prepared 600rpm for 7 min(50g). 1ml of the i-PRF was applied in to the osteotomy site and the implant surface will be thoroughly coated followed by placing of the implant. The surgical site was thoroughly irrigated and debrided. Flap closure was achieved using 3-0 silk sutures to protect the implant site.

Intervention model description
Two groups were made one test and control. All the subjects were treated with immediate implants. In the test group subjects, injectable platelet-rich fibrin was coated around dental implants and was also injected in the socket. The control group received only dental implants.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Crestal bone level | 6 months | Measured using CBCT scan both on mesial and distal sides .The coronal surface of the implant will be taken as reference line from where two perpendicular lines are dropped on both mesial and distal aspect of implants to first bone to implant contact. |
| Bone density | 6 months | measured using CBCT scan using Hounsfield units at mid point of the implant both on mesial and distal side with coronal portion of implant as reference line. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Angular bleeding index | 6 months | A periodontal probe passed along the buccal margin at 60 degrees angulation in gingival sulcus. The resultant bleeding is recorded as present (+) or absent (-). |
| Peri-implant Probing pocket depth | 6 months | measured mesially and distally using a UNC-15 probe (university of North Carolina-15 periodontal probe- Hu-Friedy, Chicago, IL, USA). |
| Pink esthetic score | 6 months | Digital photographs will be used for evaluation of the pink esthetic score(PES). Charts containing the seven variables will be designed. These include: mesial papilla, distal papilla, soft tissue level, soft tissue contour, alveolar process deficiency, soft tissue colour and texture. Each variable will be recorded with a 2-1-0 score, where 2 is the best and 0 is the poorest score. |
