Abstract

After tooth extraction, a significant reduction of the alveolar ridge in
the horizontal/buccal-palatal dimension occurs if the socket does not
receive some types of treatment. So the maturation and mineralization of
the newly formed bone in the extraction socket can be accelerated or
improved by bone graft materials.
In the present study, the efficacy of Nanobone bone graft on socket
healing process after tooth extraction was evaluated
The study was conducted on twenty eight mature (ranged from 1-2
years old) male Mongrel dogs, weighing about 15-20 kg each.
The animals were divided into three groups:
 group Ι (control group): consisted of four animals with extracted
lower 2nd premolar.
 group II: consisted of twelve animals; the animals in this group
were treated with nano hydroxyapatite (NanoBone®) to seal the
socket after simple a traumatic extraction of lower 2nd premolar.
 group IΙI: consisted of twelve animals; the animals in this group
were treated with nano hydroxyapatite (NanoBone®) with platelet
rich fibrin (PRF) to seal the socket after simple atraumatic
extraction of lower 2nd premolar.
One animal from group I and three animals from group II and group
III were sacrificed with an overdose of anesthesia at 15,30,45and 90 days
postoperative intervals. Microscopic examinations were done for the
histological sections of extracted bony socket.
Summary & Conclusion
49
On the basis of the histological results recorded in current study, it
was observed that the materials tested exhibited varying degrees of bone
regeneration. Direct bone apposition was evident to the implanted
materials on a different level.
group III (Nanobone + PRF) showed highest results in the rate of
bone formation more than group II (Nanobone alone) and group I
(control group) respectively through the postoperative study intervals.
Also the bone formation in group III (Nanobone + PRF) & group II
(Nanobone alone) showed higher quality more than group I (control
group) after 45 and 90 days postoperative study intervals
