Children and adolescents account for a large portion of dental patients due to trauma. It is known that the trauma of maxillary anterior teeth is most common. In the case of damage to the periodontal ligament, which is a tooth support tissue, in the growing child, osseo?integration occurs between the cementum and alveolar bone, and the damage to the periodontal ligament leads to inflammation, which causes osteoclasts to infiltrate. When the replacement resorption progresses, irregular resorption occurs in which the root margin is replaced by alveolar bone. In the case of growing children, this replacement resorption interferes with the vertical growth of the alveolar bone and causes the inclination and space loss of adjacent teeth as the tooth submerges. In 1984, Malmgren et al. tried to decoronation as an aesthetic alternative to preserving adjacent alveolar bones and preventing infra?occlusion in the tooth that had undergone such replacement. Decoronation can preserve the width and height of alveolar bone, thereby reducing the need for alveolar bone augmentation required for implantation or prosthesis treatment in the future. We report two cases with clinically satisfactory results for decoronation of maxillary central incisor after trauma. During the three?year observation period, the adjacent alveolar bone was maintained in both cases.
