To establish a new method of treating severe type of intrusion type of injuries to teeth. The prognosis of these injuries is poor. Poor prognosis is attributed to the development of multiple complications from various components of teeth. We described the various phases to prevent and treat various complications.
Most common sequelae to intrusion injuries are alveolar bone loss, resorption of teeth, and gingival recession. Plasma-rich fibrin (PRF) possesses various biological elements for optimal healing and prevention of the above.
A 9-year-old female patient suffered intrusion injury to 21 with no root fractures. Since intrusion was severe type, surgical repositioning with flexible splinting is done. Complications such as alveolar bone loss and gingival recession have occurred, which were successfully treated with PRF. To prevent development of resorption, calcium hydroxide was used as intracanal medicament and doxycycline was used to prevent surface resorption.
PRF is effective not only in promoting healing, bone deposition but also prevents secondary infection of the wound. Hence, it is simple, easy, and inexpensive biomaterial for treating intrusion injuries of teeth.
Considering the various properties associated with PRF, it could be a key for treating other type traumatic injuries to teeth.

建立一种治疗严重型嵌入性牙损伤的新方法。这类损伤的预后较差,其原因是牙齿各组成部分出现多种并发症。我们描述了预防和治疗各种并发症的不同阶段。
嵌入性损伤最常见的后遗症是牙槽骨吸收、牙齿吸收和牙龈退缩。富血小板纤维蛋白(PRF)具有多种生物成分,有利于实现最佳愈合并预防上述情况。
一名9岁女性患者的21号牙发生嵌入性损伤,无牙根骨折。由于是严重型嵌入,遂进行了手术复位并采用弹性夹板固定。出现了牙槽骨吸收和牙龈退缩等并发症,使用PRF成功治愈。为防止吸收的发生,根管内使用氢氧化钙,并用强力霉素预防表面吸收。
PRF不仅在促进愈合、骨沉积方面有效,还能预防伤口继发感染。因此,它是治疗牙嵌入性损伤的一种简单、易行且廉价的生物材料。
鉴于PRF的多种特性,它可能是治疗其他类型牙外伤的关键。
