Maxillary incisors and specifically their crowns are the most common teeth involved in dental trauma because of their exposed position in the dental arch. Traumatized anterior teeth require quick functional and esthetic repair. In the case of a complex crown fracture, with the necessity of endodontic treatment, fiber-reinforced posts (FRC) were used to create a central support stump to restore the dental morphology.
A 24-year-old male patient came to the dental clinic with dental injury to the maxillary left central incisor with a chisel-type fracture that extended subgingivally with a widely open pulp chamber. The patient reported a sports injury had occurred 1 day before. Provisional reposition of the crown was completed using a composite splint and after that endodontic treatment has been performed. Two days later, a fiber-reinforced composite resin post was placed into the canal and adhesive reattachment of the fragment also completed. The tooth was prepared for a composite resin veneer in the gingival third of the vestibular surface because of a visible fracture line.
The combined use of a fiber-reinforced composite resin post and the original crown fragment is a simple and efficient procedure for the treatment of traumatized anterior teeth that appears to offer pleasing esthetic and functional results that is less invasive than conventional prosthodontic treatment.
上颌切牙,尤其是其牙冠,是牙外伤中最常受累的牙齿,因为它们在牙弓中位置暴露。外伤的前牙需要快速进行功能和美学修复。对于复杂的牙冠折裂且需要进行根管治疗的情况,可使用纤维增强桩(FRC)来创建一个中央支撑桩以恢复牙齿形态。
一名24岁男性患者因上颌左中切牙牙外伤前来牙科诊所,该牙为凿状折裂,折裂延伸至龈下,髓腔广泛开放。患者称1天前发生了运动损伤。使用复合夹板完成了牙冠的临时复位,之后进行了根管治疗。两天后,将纤维增强复合树脂桩放入根管,并完成了碎片的粘结再附着。由于可见折裂线,在前庭面牙龈三分之一处为该牙制备了复合树脂贴面。
纤维增强复合树脂桩与原牙冠碎片联合使用是治疗外伤前牙的一种简单有效的方法,似乎能提供令人满意的美学和功能效果,且比传统修复治疗的侵入性更小。
