Ridge preservation with the socket-shield technique and immediate provisionalization for delayed implant placement. A...

The present case report with medium-term follow-up aims to report on the successful outcomes of ridge preservation using anorganic bovine bone mineral (ABBM) combined with the socket-shield technique (SST) in conjunction with immediate ovate pontic provisionalization of the extraction site, followed by delayed flapless implant placement and immediate implant provisionalization in the rehabilitation of the maxillary anterior esthetic region. Clinical protocol: Three consecutive patients with failing maxillary anterior teeth were treated with this protocol. The alveolar ridge dimension was preserved utilizing ABBM, combined with the retention of a partial tooth root segment in the buccal portion of the extraction socket, to minimize ridge resorption following tooth extraction. An immediate fixed provisional restoration with an ovate base in direct contact with the extraction site was fabricated and delivered immediately to maintain the soft tissue contour. At 4 months postextraction, flapless implant placement was performed via a computer-generated surgical guide, along with immediate implant provisionalization. Definitive restorations were delivered 4 months following implant placement.

At the 2-year follow-up after loading, prosthetic and implant success was demonstrated, with a favorable esthetic outcome and a high level of patient satisfaction.

The immediate ovate pontic provisionalization in conjunction with ridge preservation combining ABBM and the SST, followed by flapless computer-guided implant placement with an immediate implant provisionalization protocol, as proposed in this article, offers a viable method to minimize alveolar ridge resorption as well as optimize esthetic outcomes.
