This second of a two-part series reviews the single dental implant as the most current treatment alternative for replacement of a missing or lost maxillary lateral incisor. Assessments of dental maturity for implant placement, implant space requirements, surgical and restorative influence on soft tissue profiles, and implant success are reviewed.
Recent data indicates that implant success rates are high, and esthetics and soft tissue profiles appear to be stable for maxillary lateral incisor implants. Implant placement should be assessed by dental maturity of the specific patient as opposed to chronological age, and implant spacing should be developed and assessed by all team members.
Implant replacement of a missing lateral incisor is a predictable treatment mode if implant placement is deferred until dental maturity and then accurately placed in a well-developed site. Treatment involves more complicated planning and execution from team members than other alternatives, but innovations in techniques and materials render it a favorable alternative for lateral incisor replacement.
Implant restoration of a missing or lost maxillary lateral incisor is surgically and restoratively more complex than space closure or a resin-bonded fixed dental prosthesis but demonstrates high success rates and high esthetic potential when team members follow strict treatment protocols.
这是两部分系列中的第二部分，回顾了单颗牙种植体作为缺失或脱落上颌侧切牙的最新治疗选择。评估种植体放置的牙齿成熟度、种植体空间要求、手术和修复对软组织轮廓的影响以及种植体的成功率。
最近的数据表明，种植体的成功率很高，上颌侧切牙种植体的美观和软组织轮廓似乎很稳定。种植体的放置应根据特定患者的牙齿成熟度进行评估，而不是根据年龄进行评估，并且种植体间距应由所有团队成员开发和评估。
如果将种植体放置推迟到牙齿成熟后，并准确地放置在发育良好的部位，缺失侧切牙的种植体替代是一种可预测的治疗方式。与其他替代方案相比，治疗需要团队成员进行更复杂的规划和执行，但技术和材料的创新使其成为替代侧切牙的有利选择。
缺失或脱落的上颌侧切牙的种植体修复在手术和修复方面比间隙关闭或树脂粘结固定修复体更为复杂，但如果团队成员遵循严格的治疗方案，种植体具有很高的成功率和很高的美观潜力。
