Background and aims. There are
some studies comparing bone replacement grafts. The aim of this study was
clinical evaluation of the effect of Osteon (as a new bone material) and
Bio-Oss (Bovine-derived hydroxyapatite) in the treatment of mandibular molar
class II furcation defects in humans.
Materials and methods. Eleven patients (10 females and 1 male, age
range of 27-59 years ; mean age of 45.5±11.8 years) who had at least 22
mandibular class II buccal or lingual furcation defects were treated either
with Osteon (as the case group) or Bio-Oss (as the control group). Each defect
was randomly assigned to either the case group or the control group. Clinical parameters
and the soft tissue and hard tissue measurements, including plaque index (PI),
gingival index (GI), gingival recession of furcation area (GR), pocket depth
(PD), clinical attachment level (CAL), horizontal defect depth (HDD), vertical
defect depth (VDD) were recorded at baseline and six months after surgery. Data
were analyzed using t-test or Wilcoxon's test.
Results. Similar
healing results were observed for both treatments. The results showed
significant probing depth reduction (case group: 0.77 mm and control group:
0.84 mm) and HDD reduction (case group: 0.51 mm and control group: 0.8 mm) and
PI reduction. There was not statistically significant difference between the
groups in all soft and hard tissue parameters.
Conclusion. The
results of this study showed that the effect of using Osteon as a bone graft
material is the same as that of Bio-Oss in the treatment of mandibular class II
furcation defects.
