The congenital absence of permanent teeth, also known as partial anodontia, is a relatively common problem. The patient missing one or both lateral incisors is a frequent occurrence. The treatment of missing laterals involves both functional and esthetic considerations. Options include: cuspid lateralization; implant placement; conventional three-unit bridge; Maryland bridge; and a fiber-reinforced composite bridge (direct or indirect). Direct fiber-reinforced composite bridges provide a minimally invasive restorative option that allows for future implant placement. Selection of appropriate fiber reinforcement and placement of the fibers allows long-term clinical success. Adherence to appropriate adhesive protocol is mandatory.
恒牙先天性缺失,也称为部分无牙症,是一个相对常见的问题。患者缺失一颗或两颗侧切牙的情况屡见不鲜。侧切牙缺失的治疗涉及功能和美观两方面的考虑。治疗选项包括:尖牙侧移;种植体植入;传统三单位桥体;马里兰桥体;以及纤维增强复合桥体(直接或间接)。直接纤维增强复合桥体提供了一种微创修复选择,为未来的种植体植入留出空间。选择合适的纤维增强材料并正确放置纤维可实现长期临床成功。必须严格遵守适当的粘结方案。
