Decoronation of an ankylosed tooth: Postoperative restoration by means of an intermediate fixed orthodontic laboratory device.


Rehabilitation of missing decoronated permanent incisors in growing children and adolescents is a major challenge. The psychologic impact of the loss of an incisor is significant due to its immediate influence on facial appearance. Final restoration is planned only after skeletal growth cessation. Consequently, the fabrication and installation of an immediate temporary restoration, which is expected to remain in place for a long period, must meet the patient's esthetic demands and be durable in the oral environment. Several proposed removable and fixed restorations have presented significant shortcomings. The purpose of this report is to suggest a comfortable dental device for restoring the missing permanent tooth with improved esthetic, functional, and psychologic benefits. An alternative fixed orthodontic laboratory fabricated appliance for permanent tooth restoration is described among children with posttraumatic tooth decoronation. Unlike removable restorative appliances, this fixed device is not dependent on the child's compliance. Esthetically, no metal part is exposed in the anterior region and the architecture is more sturdy and stable, with minimum interruption to the alveolar ridge's vertical development.


An alternative fixed orthodontic laboratory appliance is described for intermediate restoration of a missing permanent tooth.


A posttrauma intermediate fixed orthodontic appliance is a beneficial solution from esthetic, psychologic, functional, and economic perspectives for replacing missing anterior maxillary teeth. This device may be worn by patients for a long period until final restoration is indicated.
