Demineralized Bone Allograft Fibers Versus Particulate In Sinus Augmentation

Purpose

The purpose of this clinical trial is to assess if the addition of DFDBA fibers to DBBM results in greater vital bone formation than the addition of DFDBA particles to DBBM. The study team will examine the effects of the addition of DFDBA fibers to DBBM on vital bone formation. Specifically, we will assess histologically the percent vital bone formation with each of the groups during implant placement, six months after the sinus augmentation procedure. We will also evaluate the radiographic volume achieved with both groups of materials.

DFDBA Fibers with DBBM
After standard of care elevation of the Schneiderian membrane, a mix of DFDBA fibers with DBBM (50%-50%) will be introduced in the space created between the Schneiderian membrane and the alveolar crest of the maxilla.

Detailed Description

This entire protocol involves procedures that are standard care and will randomize subjects to of one two routine care procedures. Patients needing maxillary sinus augmentation will be enrolled. There will be two subject groups in this study both of which will randomized to one of two standard care procedures. No risk or benefit is expected from being assigned to either group as both procedures are both standard care. In both groups a bone sample (core) will be obtained as a by-product of implant placement. Bone will not be extracted solely for research purposes, the bone sample attained for research will only be from bone left over after the SOC implant placement. Allocation of subjects into test group or control group will be based on numbers drawn from a stack of sealed envelopes.
