Lateral Sinus Augmentation Utilizing Bovine Bone Mixed with Platelet-rich Fibrin

Lateral Sinus Augmentation Utilizing Bovine Bone Mixed with Platelet-rich Fibrin: Evaluation of Graft Volume Changes Based on CBCT Imaging

Background:

In sinus augmentation procedure, graft resorption remains a major dilemma of various graft materials.

Objective:

To estimate the graft volume changes following lateral sinus augmentation utilizing cone beam computed tomography.

Methods: A total of 34 lateral sinus augmentation operations were performed and 50 dental implants were concomitantly inserted. The sinus augmentation cases were distributed randomly into 3 groups according to graft material: Group A comprised utilizing deproteinized bovine bone alone, group B using deproteinized bovine bone mixed with leukocyte and platelet-rich fibrin, and group C employing deproteinized bovine bone mixed with advanced platelet-rich fibrin. Cone-beam computed tomography was obtained 2 weeks (baseline record) and 24 weeks postoperatively for the measurement of the graft volume changes.

Inclusion Criteria:

• requiring lateral sinus lift for implant placement

Exclusion Criteria:

• available bone permits implant placement without need for sinus lifting
