摘要
Severe horizontal bone deficiency of the maxillary anterior region is considered a major challenge in reconstruction and successful implant placement. Various approaches have been developed to augment bone volume. Of these approaches, onlay bone graft, alveolar bone splitting, and guided bone regeneration have been suggested.A 22-year-old female patient, with no previous medical history, presented to the Department of Oral Implantology, Wuhan University due to a missing right maxillary incisor. The X-ray results showed severe horizontal bone deficiency, with an available bone width of 3.1-4.0 mm. The two bone blocks sandwich technique was performed to augment the bone volume. After 6 months healing, X-ray results showed that the newly formed alveolar ridge dimension increased to 4.7-9.5 mm horizontally. Implant insertion surgery was performed and all-ceramic restorations were fabricated. The implant was stable at the 1-year follow-up visit after restoration, and the X-ray showed a stable bone level around the dental implant. The scores for the pink esthetic score and white esthetic score were 12 and 8, respectively, and the patient was satisfied with the esthetic outcome.The two bone blocks sandwich technique may be an alternative treatment option in augmenting severe horizontal bone deficiency of the anterior maxilla.
