ASSESSMENT OF SINUS TENTING OF SIMULTANEOUS DENTAL IMPLANTS WITH AND WITHOUT SOLID PLATELET RICH PLASMA FOR MAXILLARY SINUS LIFT WITHOUT GRAFTING

Introduction: Platelet-rich plasma (PRP) is an autologous product with a nativecontent of fibrinogen and a high concentration of platelets (5–10 times higher thanwhole blood) Platelets contain growth factors that can trigger cell reproduction andstimulate tissue regeneration or healing. So, we used PRP around implants to acceleratehealing and enhance bone formation quality. Aim: This clinical study aimed to assesssinus tenting of simultaneous dental implants with and without PRP for maxillary sinuslift without bone grafting. Methods: This clinical, trial was carried out on ten patientsrequired bilateral sinus lifts in upper posterior region. Implants inserted simultaneouslywith the sinus lift procedure without grafting. Bilateral sinus tenting was performed foreach patient, then the patients were grouped as: Group I (patients’ one side as a studygroup): obtained a solid PRP was administered above and around the implant. Group < br />B (patients’ other side as a control group): left without loading solid PRP. The secondstagesurgery had been conducted to expose the implant fixture & for prosthetic phasecompletion after 6 months. Assessments were done clinically by Visual analog scale forpain, measurement of edema, implant stability assessment by Osstel (ISQ), surgery timefactor and postoperative complication; and radiographically to assess the bone density,vertical bone gain after six months and crestal bone changes. Results: No significantdifference existed between two groups in pain, edema scores, implant stability, bonedensity and vertical bone gain at T0, no significance differences between two groupswere found in bone density, vertical and crestal bone changes at T6. Significancedifferences between both groups existed with better results in study groups in pain andedema at T1 and T2 and higher values of implant stability in study group at T6. Surgicaltime was longer in study group. Tenderness and nasal obstruction were lesser in studygroup and no nasal bleeding in both groups. Conclusions: Application of solid PRP insinus tenting procedure of simultaneous dental implants for maxillary sinus lift withoutbone grafting can improve pain, edema scores and implant stability.
