The replacement of single anterior teeth by means of endosseous implants implies the achievement of success in restoring both aesthetic and function. However, the presence of wide endoperiodontal lesions can lead to horizontal hard and soft tissues defects after tooth extraction, making it impossible to correctly place an implant in the compromised alveolar socket. Vertical augmentation procedures have been proposed to solve these clinical situations, but the amount of new regenerated bone is still not predictable. Furthermore, bone augmentation can be complicated by the presence of adjacent teeth, especially if they bring with them periodontal defects. Therefore, it is used to restore periodontal health of adjacent teeth before making any augmentation procedures and to wait a certain healing period before placing an implant in vertically augmented sites, otherwise risking to obtain a nonsatisfactory aesthetic result. All of these procedures, however, lead to an expansion of treatment time which should affect patient compliance. For this reason, this case report suggests a surgical technique to perform vertical bone augmentation at a single gap left by a central upper incisor while placing an implant and simultaneously to regenerate the periodontal attachment of an adjacent lateral incisor, without compromising the aesthetic result.
通过骨内种植体替换单个前牙意味着在恢复美观和功能方面都取得成功。然而,广泛的牙周病变的存在可能导致拔牙后水平方向的硬组织和软组织缺损,使得无法在受损的牙槽窝中正确植入种植体。已经提出了垂直增量手术来解决这些临床情况,但新再生骨的量仍然不可预测。此外,骨增量可能因相邻牙齿的存在而变得复杂,特别是如果它们伴有牙周缺损。因此,在进行任何增量手术之前,通常会先恢复相邻牙齿的牙周健康,并在垂直增量部位植入种植体之前等待一定的愈合期,否则可能会获得不理想的美学效果。然而,所有这些程序都会导致治疗时间延长,这可能会影响患者的依从性。因此,本病例报告提出了一种手术技术,即在植入种植体的同时,对上颌中切牙留下的单个间隙进行垂直骨增量,并同时再生相邻侧切牙的牙周附着,而不影响美学效果。
