Evaluation of Implant Stability Following Sinus Augmentation Utilizing Bovine Bone Mixed with Platelet-Rich Fibrin

Abstract

Background: Lateral sinus augmentation and simultaneous insertion of dental implants is a highly
predictable procedure and associated with high rate of implants success.
Aims: To evaluate implant stability changes following maxillary sinus augmentation utilizing deproteinized
bovine bone alone or mixed with platelet-rich fibrin.
Materials and Methods: A total of 34 lateral sinus augmentation procedures were performed and 50 dental
implants simultaneously installed. The lateral sinus augmentation cases were allocated randomly into 3
groups: Group A comprised 13 procedures and 21 dental implants utilizing solely deproteinized bovine bone.
Group B involved 10 cases and 16 dental implants using deproteinized bovine bone mixed with leukocyte
and platelet-rich fibrin. Group C included 11 operations and 13 dental implants employing deproteinized
bovine bone mixed with advanced platelet-rich fibrin. Resonance frequency analysis test was performed
immediately after implant installation and 24 weeks postoperatively for the measurement of the implant
stability.
Results: Implant stability quotient values increased significantly for all study groups 24 weeks after dental
implants installation (P= 0.001). The implant stability quotient at T1 (day of implant installation) was 56.93
±12.01 for group A, 58.34 ±12.82 for group B, and 61.35 ±8.47 for group C. The implant stability quotient
at T2 (24 weeks after implant insertion) was 69.17 ±5.10, 69.43 ±5.32, and 68.50 ±7.44, respectively.
Conclusion: The addition of leukocyte and platelet-rich fibrin or advanced platelet-rich fibrin to the bovine
bone for sinus floor augmentation did not increased the implant stability quotient value in comparison to the
bovine bone alone.
