The replacement of a lost mandibular incisor involves a variety of therapeutic possibilities, such as conventional fixed dental prosthesis, implant-supported prosthesis, and resin-bonded bridge, with treatment selection based on both general and local selection criteria. This case focuses on a young female patient presenting with the absence of the left mandibular incisor. A two-retainer, high-strength, monolithic, multi-layered zirconia RBFDP (resin-bonded fixed dental prosthesis) was chosen, fabricated through computer-aided design and computer-aided manufacturing technology. This approach leverages the durability of polycrystalline ceramics alongside the color gradient technology of zirconia disks, ensuring minimally invasive preparation for optimal bonding. This type of restoration not only preserves dental tissues and provides long-term durability but also adapts to dental changes, reducing the risk of infraocclusion over time, an issue often associated with implant-supported restoration.
缺失下颌切牙的修复有多种治疗选择，如传统固定义齿、种植支持式义齿和树脂粘结桥，治疗方案的选择基于一般和局部选择标准。本病例聚焦于一名年轻女性患者，其左下颌切牙缺失。选用了一种双固位体、高强度、整体式、多层氧化锆树脂粘结固定义齿（RBFDP），通过计算机辅助设计和计算机辅助制造技术制作而成。这种方法利用了多晶陶瓷的耐久性以及氧化锆盘的颜色渐变技术，确保了微创预备以实现最佳粘结。这种修复方式不仅能保留牙体组织并提供长期耐久性，还能适应牙齿变化，降低随着时间推移出现咬合过低的风险，而咬合过低问题常与种植支持式修复相关。
