Over time, patients treated in developmental stages of implantology may need additional treatment,as teeth adjacent to implants may fail and require replacement themselves with new implants. Blending newer implant rehabilitations into a dentition with existing implant-supported restorations can be challenging. The use of implants with a subcrestal angle correction (SAC) enables predictable screw-retained anchorage of temporary and definitive restorations. An SAC implant often can be placed into the palatal bone of an extraction socket, along the incisal angle of the crown, allowing screw retention of the prosthesis. This case report demonstrates the use of both straight and SAC implants combined with hard- and soft-tissue augmentation and serial provisionalization to replace hopeless teeth adjacent to pre-existing implants and improve esthetics in the anterior maxilla.
随着时间的推移,接受种植学发展阶段治疗的患者可能需要额外的治疗,因为相邻的牙齿可能会失效,需要用新的种植体来替换。将更新的种植体修复体融入到具有现有种植体支持修复体的牙列中可能具有挑战性。使用具有骨下倾角度校正(SAC)的种植体可实现临时和永久性修复体的可预测螺钉固位。SAC 种植体通常可以放置在拔牙窝的腭骨中,沿着牙冠的切缘,允许通过螺钉固定修复体。本病例报告展示了使用直型和 SAC 种植体结合软硬组织增量和系列临时修复体来替换相邻于先前存在的种植体的无望牙齿,并改善上前牙的美观度。
