The restoration of the missing maxillary incisors is a complex and delicate treatment challenge. When implant therapy is used, proper treatment planning is critical, as selecting the proper number, location, and dimension of the implants is a difficult task. Thus, this article discusses the issues that must be addressed during diagnosis and treatment planning to achieve a predictable esthetic outcome when using implants to replace the maxillary incisors. The advantages and disadvantages of several implant-supported treatment options-using a combination of regular- and narrow-neck implants-are presented. Ultimately, the use of narrow-neck implants at the lateral incisor sites is presented as the best option for ensuring excellent esthetic outcomes, and the corresponding indications and contraindications are discussed. Further, all treatment options are ranked based on the predictability of their esthetic outcomes.
上颌切牙缺失的修复是一项复杂而精细的治疗挑战。当采用种植治疗时，恰当的治疗计划至关重要，因为选择合适的种植体数量、位置和尺寸是一项艰巨的任务。因此，本文讨论了在诊断和治疗计划过程中必须解决的问题，以便在使用种植体替代上颌切牙时获得可预测的美学效果。文中介绍了几种种植支持治疗方案（使用常规颈和窄颈种植体组合）的优缺点。最终，提出在侧切牙部位使用窄颈种植体是确保出色美学效果的最佳选择，并讨论了相应的适应证和禁忌证。此外，根据美学效果的可预测性对所有治疗方案进行了排序。
