摘要:

牵引保存患者健康的龈下残根是当前修复与正畸联合治疗的经典内容。以满足最终目标修复体空间(TRS)需求为核心,通过TRS数字化模型,可以选择预设适合的龈下残根的最终牵引位置,并自动评估牵引后的冠根比、最小冠高度等关键参数后,预估治疗时间,并排除预设位置不良的病例,最终获得符合TRS的正畸牵引-修复方案,可以有效地减少牵引治疗时间,也提高了整个修复正畸联合治疗的效率和疗效。

关键词: 龈下残根, 正畸牵引, 计算机辅助设计

Abstract:

The use of orthodontic traction to preserve healthy subgingival residual root is a classical method combining the treatment of restoration and orthodontics. Based on the target restoration space (TRS), by establishing a TRS digital model, the final traction position of the subgingival residual root can be preset. After evaluating the key parameters such as crown-to-root ratio and minimum crown height, clinicians can estimate the treatment time and exclude cases with bad preset position. The time of traction treatment can be effectively reduced, and the efficiency and efficacy of the entire treatment can also be improved.

Key words: subgingival residual root, orthodontic traction, computer-aided design
