Single visit reconstruction of the fractured crown can be completed with composite resins if there is no bleeding due to the soft tissue injury. Clinical inspection revealed a complex crown fracture of the central incisor as well as a simple horizontal fracture of the lateral incisor crown of the enamel-dentin type. Vertical fracture separated the palatal enamel wall from the rest of the lateral incisor crown. After the completion of the endodontic sanitation, root canals were prepared for prefabricated composite posts and crown reconstructions were performed with the Finger Tip Technique by using composite resin materials. The advantage of this kind of reconstruction is preservation of the hard dental crown tissue removed in case of prosthetic therapy, especially in younger patients. Reconstruction can be finished in one visit, without the need for a dental technician and laboratory.
如果软组织损伤没有出血，复合树脂可用于一次性完成冠折修复。临床检查发现中切牙为复杂冠折，侧切牙冠为简单的牙釉质-牙本质型水平骨折。垂直骨折将侧切牙腭侧牙釉质壁与牙冠其余部分分开。完成牙髓清理后，预备根管以植入预成复合桩，并采用指尖技术使用复合树脂材料进行冠修复。这种修复方法的优点是保留了在进行修复治疗时去除的硬牙冠组织，尤其适用于年轻患者。修复可在一次就诊时完成，无需牙科技师和实验室。
