Guided tissue regeneration (GTR) is a successful treatment procedure of periodontal reconstructive surgery. Adverse effects can be observed after GTR procedure, but external root resorption is rarely reported at clinical studies. Invasive cervical resorption is a clinical term used to describe a relatively uncommon, insidious, and often aggressive form of external root resorption.
The present case demonstrates an invasive cervical resorption that is a potential late complication of GTR in a maxillary canine of a 59-year-old male patient. After the surgical intervention and root canal treatment, the resorption was subsequently sealed with mineral trioxide aggregate.
The 1-year follow-up demonstrates no pathologic changes on clinical and radiographic examination.
This case report presents a treatment strategy that might improve the healing outcomes for patients with invasive cervical resorption.
引导组织再生（GTR）是牙周重建手术的一种成功治疗方法。在 GTR 手术后可能会观察到不良反应，但在临床研究中很少报道外部根吸收。侵袭性颈吸收是一个临床术语，用于描述一种相对罕见、隐匿且通常具有侵袭性的外部根吸收形式。
本病例展示了上颌尖牙 GTR 后可能发生的一种侵袭性颈吸收的潜在迟发性并发症。在手术干预和根管治疗后，用三氧化矿物聚合体（mineral trioxide aggregate，MTA）封闭吸收部位。
1 年随访时临床和影像学检查未见病理性改变。
本病例报告提出了一种治疗策略，可能改善侵袭性颈吸收患者的愈合效果。
