Monitoring Of Implant Stability When Placed Simultaneously In Platelet Rich Fibrin Enhanced Maxillary Sinus Bone Augmentation

Abstract

Background: Restoring posterior maxilla with implants is challenging due to lack of bone quantity and quality.Objective: Assess the effect of adding platelet rich fibrin (PRF) to bovine bone mineral (Bio oss) as sinus graft with simultaneous implant placement. Patients and methods:Sixteen implants were placed in 16 augmented sinuses divided into two groups; the first (study) group sinus augmentation was done using Bio oss and PRF and the second (control) group using Bio oss alone. Implant stability and bone density were assessed. Results:The sinuses grafted with Bio oss mixed with PRF showed significantly higher bone density and implant stability after 6 months. Conclusion:The use of Bio oss mixed with PRF as a graft materiel in sinus lifting procedure is highly superior to Bio oss alone with respect to the implant stability and bone density around the implant.

Review on evaluation of using piezoelectric ultrasound surgery versus conventional technique in sinus lifting procedure

“…An rise in antral pneumatization occurs as a result of continual bone remodeling, lack of stimulation, and loss of bone height and density [8]. The maxillary sinus pneumatization is caused by progressive hollowing out of alveolar process of apical aspect mediated by osteoclasts and by increase in positive intra-antral pressure [9]. The remaining vertical bone height is reduced in this case, making normal implant placement challenging [10].…”
