THE EFFECT OF BIOSCAFFOLD ALVELAC™ IN PRESERVATION OF ALVEOLAR BONE AFTER EXTRACTION OF TEETH (CLINICAL AND RADIOGRAPHIC STUDY)

Abstract

ABSTRACT Introduction: After tooth extraction, the extraction socket heals by forming a blood clot which leads to the formation of new bone within 3-4 months. Although bone deposition in the socket will continue for several months, it will not reach the crestal level of the neighboring teeth. Objective: Is to clinically and radiographically evaluate the use of Bioscaffold Alvelac™ in preservation of dimensional measure of alveolar bone after extraction of teeth. Materials and methods: This study was conducted on twelve patients divided in to two equal groups (study group and control group). Indicated for extraction of anterior maxillary teeth, in the study group, the bioscaffold Alvelac™ was inserted into the empty socket after extraction and was supported by 3-0 silk with figure of eight sutures. In the control group, extraction of upper anterior teeth was done without introducing any material and the wound was sutured. Results: There was a statistically significant decrease of alveolar bone width and height in both groups at three months postoperative interval compared with the bone width and height at the immediate postoperative period. Conclusion: Immediate tooth extraction stabilizes the bioscaffold Alvelac™ material in the socket and allows it to act as a scaffold for bone deposition. From this study, it is clear that, this material allows preservation of the dimensional measure of the alveolar bone.
