Abstract
Objective: The aim of this randomized clinical study was to compare changes in alveolar ridge dimensions six months after surgery using an alveolar ridge preservation (ARP) technique with anodized titanium foil (Tseal) and blood clot, compared to natural healing.
Materials and Methods: Twenty-four patients requiring extraction of a single hopeless tooth in maxilla were included in this randomized controlled clinical trial. Participants were randomly allocated to either the test group, in which extraction sockets were protected using anodized titanium foil associated with blood clot stabilization, or the control group, in which sockets healed spontaneously after tooth extraction. Cone-beam computed tomography (CBCT) scans were obtained at baseline and after 6 months. Horizontal ridge dimensions were measured at 1 mm, 3 mm, and 5 mm below the palatal crest.
Results: Both groups demonstrated reduction in horizontal ridge dimensions after 6 months. However, the test group showed significantly greater preservation of alveolar ridge width compared with the control group at the 1-mm and 3-mm levels below the palatal crest (p < 0.05). At the 5-mm level, dimensional changes were less pronounced and no significant intergroup differences were observed. Overall, the test group demonstrated greater maintenance of horizontal ridge dimensions throughout the healing period.
Conclusion: The use of anodized titanium foil associated with blood clot stabilization demonstrated beneficial effects on alveolar ridge preservation after tooth extraction, particularly in the coronal portion of the socket, when compared with spontaneous healing. This minimally invasive approach may represent a viable alternative for reducing post-extraction horizontal ridge resorption without the use of grafting materials.
