Esthetic Zone Reconstruction Combining Root Retrieval and Guided Bone Regeneration With a Non‐Resorbable Membrane for Implant Rehabilitation: Case Report

Background After multiple traumatic episodes, an avulsion of tooth 21 resulted in noticeable hard‐ and soft‐tissue loss. Methods Soft‐tissue reconstruction began with a procedure performed through a four‐month root‐retrieval protocol, allowing for progressive coronal migration of the gingival tissues. One month after the atraumatic extraction, guided bone regeneration was performed using a combination of autologous bone, xenograft, and a titanium‐reinforced PTFE membrane to re‐establish adequate ridge volume. Due to early membrane exposure, the implant was placed at five and a half months in the correct three‐dimensional position. Soft‐tissue shaping was subsequently carried out with a provisional crown over a period of six months, until delivery of the final zirconia cemented‐screw crown. Results At the 18‐month follow‐up, the hard and soft tissues remained stable, with no complications. Conclusions The patient's expectations for both aesthetic and functional outcomes were achieved.
