Abutment manipulation, namely repeated screwing and unscrewing may have an affect on the final marginal bone level, consequently, soft tissue position around endosseous implants. In order to maintain the crestal bone level constant and avoid the apical recession of gingiva final abutment (Direct Abutment, Astra Tech) has been connected to submerged OsseoSpeed 4.5 dental implant (Astra Tech) in position of tooth 14, immediately after second surgical exposure. Following a healing period of three weeks, impression was taken using closed tray system and plastic impression pic-up for laboratory manufacturing of zirconium crown restoration. The functional and aesthetic result of the reconstruction was highly met patient is the satisfaction. The maintenance of marginal bone level and the excellent health of the peri-implant tissues, as registered at 6-month recall, may support the benefit of the idea of final abutment insertion immediately after one-, or two-stage surgery.
基台操作，即反复旋拧和松开，可能会影响最终的边缘骨水平，进而影响骨内种植体周围的软组织位置。为了保持牙槽嵴骨水平恒定并避免牙龈最终基台的根尖退缩，在第二次手术暴露后，立即将最终基台（直接基台，Astra Tech）连接到14号牙位置的埋入式OsseoSpeed 4.5牙科种植体（Astra Tech）上。经过三周的愈合期后，使用封闭式托盘系统和塑料印模取模，以便在实验室制作锆冠修复体。重建的功能和美学效果高度满足了患者的满意度。在6个月复查时记录到的边缘骨水平的维持以及种植体周围组织的良好健康状况，可能支持在一期或二期手术后立即插入最终基台这一理念的益处。
