PURPOSE
The surgical-orthodontic treatment of impacted maxillary canine (IMC) remains a challenge to today's clinicians. The aim of the present paper is to describe an unconventional treatment of IMC with insertion of implant into the retained canine and 3 years follow-up.
CASE REPORT
A 55-year-old female patient attended to rehabilitate her maxillary left canine site. An unconventional approach was proposed to the patient. A large diameter tapered implant (Ø 5 × 18 mm) was inserted (Nobel Active, Kolten, Swisse). An immediate loading prosthetic rehabilitation was performed. After checking for implant stability the prosthetic steps were carried out and a single crown was delivered with Procera system.
CONCLUSION
The patient was happy of this kind of single non-invasive session for treating IMC. At the 3-year control, the implant did not show any mobility or signs of peri-implantitis clinically or radiographically. In addiction patient was satisfied of aesthetic results.
目的
上颌阻生尖牙（IMC）的外科正畸治疗对当今的临床医生来说仍然是一项挑战。本文的目的是描述一种通过将种植体植入保留的尖牙进行IMC非常规治疗及3年随访情况。
病例报告
一名55岁女性患者前来修复上颌左侧尖牙部位。向患者提出了一种非常规方法。植入一枚大直径锥形种植体（Ø 5×18 mm）（诺贝尔活性种植体，科尔滕，瑞士）。进行了即刻负重的修复治疗。在检查种植体稳定性后进行修复步骤，并用Procera系统交付了单冠。
结论
患者对这种治疗IMC的单一非侵入性治疗方式感到满意。在3年复查时，种植体在临床和影像学上均未显示任何松动或种植体周围炎的迹象。此外，患者对美学效果也很满意。
