研究目的: |
通过对比评估经磨牙区即刻种植术、位点保存术与常规拔牙后延期种植修复三种术式对牙槽嵴骨组织及软组织变化差异,为磨牙区种植修复的术式选择提供高质量的临床证据。 |

Objectives of Study: |
By comparatively evaluating dimensional changes in alveolar bone and soft tissues following three distinct protocols—immediate implant placement in the molar region, socket preservation, and conventional delayed implant placement after extraction—this study aims to generate high-level clinical evidence to inform the selection of optimal implant rehabilitation approaches in the molar region. |
