Abstract
After tooth extraction, alveolar bone resorption and labial bone plate thinning occur
due to the lack of periodontal ligaments. The socket shield method was developed to
preserve the alveolar ridge. A split-mouth study was performed in which eight patients
were treated using alloplast with socket shield on one side (alloplast group, control)
and autogenous dentin graft with socket shield on the contralateral side (dentin group,
test). After 3 months, a trephine bone core was collected from all sites and evaluated
by histological, histomorphometric, and radiographic analysis. Thin bony trabeculae
were formed surrounding the residual alloplast, while thicker trabeculae of bone formed
and fused to the autogenous dentin. The percentage of newly formed bone was significantly
higher in the dentin group when compared to the alloplast group (P = 0.020). Radiographically, there was no significant difference in the mean percentage
increase in bone density from preoperative to post-grafting between the two groups.
Moreover, when comparing the change in labial bone level from preoperative to 3 months
post-grafting between the two groups, there was no significant difference. The autogenous
dentin graft combined with socket shield could be a promising technique for socket
preservation.
