Abstract：
This case series assessed the efficacy of Orthodontic Implant Site Development with Labial Root Torque (OISD-LRT) as a nonsurgical technique for addressing labial bone deficiencies in seven patients. The procedure involved strategically placing a multi-bracket of 2-3 mm apically on the hopeless teeth, gradually shifting them with Ni-Ti wires at the rate of 2 mm per month and maintaining overcorrection for 2 months before extraction. OISD-LRT consistently augmented tissue for flapless guided implant surgery, with an average treatment duration of 404Å}311.7 days. Cone-beam computed tomography (CBCT) scans at various stages revealed increases in both vertical and horizontal bone dimensions, especially in the sockets with complete labial bone loss. Despite inevitable post-extraction reductions in bone height and width, sufficient dimensions were maintained to ensure long-term implant stability. This case series highlights the effectiveness of OISD-LRT as a valuable method for horizontal bone augmentation, particularly in patients with labial bone deficiency. This approach provides a robust foundation for subsequent implant placement, showcasing its success in addressing challenging anatomical conditions and contributing to the broader field of implant dentistry.
摘要：
该病例系列评估了使用唇根扭矩（OISD-LRT）进行正畸种植部位发育作为解决7例患者唇骨缺陷的非手术技术的有效性。该程序涉及策略性地在无望的牙齿上放置2-3毫米的多托架，用Ni-Ti线以每月2mm的速度逐渐移动它们，并在提取前保持过校正2个月。OISD-LRT持续增强组织，用于无翼引导植入手术，平均治疗时间为404µ}311.7天。不同阶段的锥形束计算机断层扫描（CBCT）扫描显示垂直和水平骨骼尺寸均增加，尤其是唇骨完全丢失的插座。尽管骨高度和宽度在拔牙后不可避免地减少，保持足够的尺寸以确保植入物的长期稳定性。本系列案例强调了OISD-LRT作为一种有价值的水平骨增强方法的有效性，尤其是唇骨缺损患者。这种方法为随后的植入物放置提供了坚实的基础。展示了其在解决具有挑战性的解剖学条件方面的成功，并为更广泛的种植牙科领域做出了贡献。
