Abstract
There are various grafting materials used for socket preservation of the
alveolar ridge following tooth extraction. The purpose of this study was to evaluate
clinically and histomorphometrically healing after tooth extraction with or without
placement of a synthetic bone graft and determine the effect on alveolar ridge
preservation following extraction. 30 subjects in need of extraction of non-molar teeth
were recruited for this study. Recruited subjects were randomly assigned to the group
A (with graft material) or control (without graft material) group B. Data were recorded
at 6 months after socket preservation procedures. At 6 months, a surgical re-entry was
performed; Clinical Measurements and bone core biopsies were obtained for
histomorphometric analysis. The control group B had a mean reduction in ridge height
of 1.26mm, whereas alveolar ridge height in the test group A was 0.73mm. The test
group A was 7.33 ± 1.01 mm compared to 7.23 ± 1.13 mm in group B which were not
statistically significant (p = 0.684). Histomorphometric analysis revealed total new
bone volume in group A represented 65.6 ± 11% connective tissue 25.6 ± 10.18 %
and 8.8% was occupied by residual graft material. The mean new bone volume in
group B was 31.23 ± 7.24%, whereas connective tissue formation was approximately
68.78 ± 7.24 %. Both these values were statistically significant when compared with
group A. There was no relation with residual graft material as there was no graft
material used in group B. A positive response was observed when synthetic graft was
applied to extraction sockets, suggesting that it may be useful for preservation of ridge
height prior to dental implant placement.
