Clinicians are faced with three common treatment options for the high frequency of missing or lost maxillary lateral incisors; canine substitution, a resin-bonded fixed dental prosthesis (RBFDP), or a dental implant. A review of current data and guidelines for treatment provide new insight into making the most appropriate selection.
The incidence of maxillary incisor agenesis and loss is prevalent. Both canine substitution and RBFDPs exhibit esthetic and functional advantages and disadvantages.
Most missing lateral incisors are detected at an early age as a result of congenital absence; therefore, proper treatment of these young patients is essential. Both canine substitution and RBFDPs can provide long-term success and esthetics when carefully executed. The decision should be based on the patient's expectations, their clinical presentation, cost, and the team's ability to provide the best long-term esthetic and functional prognosis for a specific patient.
Patients regularly present for treatment of missing and lost maxillary lateral incisors. The functional and esthetic aspects of canine substitution and a RBFDP should be clearly understood relative to the clinical parameters of each patient prior to treatment.
对于上颌侧切牙缺失或丢失的高频问题，临床医生面临三种常见的治疗选择；犬齿替代、树脂粘结固定义齿（RBFDP）或种植牙。对当前治疗数据和指南的回顾为做出最合适的选择提供了新的见解。
上颌切牙先天缺失和缺失的发生率很高。犬齿替代和 RBFDP 都具有美学和功能上的优缺点。
大多数缺失的侧切牙由于先天缺失而在早期被发现；因此，对这些年轻患者的适当治疗至关重要。当犬齿替代和 RBFDP 得到精心执行时，都可以提供长期的成功和美观效果。该决定应基于患者的期望、临床表现、成本以及团队为特定患者提供最佳长期美观和功能预后的能力。
患者经常因上颌侧切牙缺失或缺失而接受治疗。在进行治疗之前，应根据每个患者的临床参数，清楚地了解犬齿替代和 RBFDP 的功能和美观方面。
