Due to a number of complicated factors, implanting the edentulous posterior maxilla is often a difficult procedure. It is stated
that maxillary sinus floor elevation is a predictable treatment option to obtain sufficient bone height and volume for implant
placement. In this study, it was aimed to compare the resorbable collagen sponges which are thought to be used in maxillary
sinus floor elevation with xenogen graft particles, histopathologically and histomorphometrically in terms of new bone formation.
For this purpose; In 16 New Zealand white rabbits, bilateral sinus floor elevation was performed, the cavities formed under the
sinus membrane were augmented by placing a collagen sponge on the right side and an equal volume of xenogen grafts on the
left side. In the postoperative period, the rabbits were sacrificed at the end of the 4th and 8th weeks, 8 each time. The obtained
samples were divided into 4 groups and evaluated histopathologically and histomorphometrically. Results: Histopathological
evaluation revealed that the two materials were biocompatible materials and formed a suitable environment for the transfer
of osteogenic cells. Histomorphometric evaluations showed that there was no difference between the materials in terms of
percentage of new bone formation. (p≤0.05) However, the newly formed bone area and osteoid area were found to be much larger
in the areas where xenogen grafts were used (p ≤0.05). Collagen sponge was unable to maintain its volume during the test period
and resorbed. Minimal resorption was observed in xenogen graft particles.
