A Clinical and Histomorphometric Evaluation of Socket Preservation Using Resorbable Collagen Membrane and an Alloplast: A Comparative Interventional Study
Journal Title: Saudi Journal of Oral and Dental Research - Year 2017, Vol 2, Issue 9
Abstract
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.
