Comparing nano-hydroxyapatite to Deprotenized bovine bone through a two-stage maxillary sinus floor elevation
AUTHOR(S): Mahmoud Ahmed, Maha Hakam and Mohamed Atef
ABSTRACT:The purpose of this study is to compare the use of Nano HA (Nanostreams) as a predictable augmentation material for two-stage maxillary sinus floor augmentation compared to deprotenized bovine bone (Tutogen) Twenty patients from both sexes between the ages of 34 –52 years were enrolled in this study. Patients were all indicated for lateral window sinus lifting with residual bone height of less than 5 mm. A titanium micro mesh was placed into the sinus and fixed to the lateral wall to maintain the elevated Schneiderian membrane in place. The twenty patients were divided into two groups, Nano hydroxyapatite (Nano streams) was used as the grafting material in the first group (Test group) while in the second group, a deprotenized bovine bone (Tutogen) was used as a control grafting material. An absorbable collagen membrane was used to cover the lateral window. An immediate and Six-month postoperative CBCT were carried out for all patients and the height of the newly formed bone beneath the mesh measured when the implant was inserted, bone-core biopsies were obtained by means of a trephine bur and submitted for histomorphometric analysis. a typical residue vertical ridge height among the 20 sinuses preoperatively was 3.68 mm +/- 0.95 mm in the Nano HA group and 3.74 mm +/-0.59 mm in DBB group. The vertical ridge height as measured on the 6-month postoperative CBCT average 12.1 mm +/- 1.53 mm for the Nano HA group and 12.6 mm +/-1.11 mm in the DBB group. The average new bone percentage in the Nano HA group was 29.84% -/+ 6.7% and 34.73% -/+ 7.9% in the DBB group. Statistical analysis proved there was no discernible difference between the two groups in terms bone height gain and percentage of new bone formation.
