[Bonding of fragments in coronal fractures]

The coronal fractures of the upper incisors for traumatic injuries represent the 8% of the total dental trauma. The use of new dentinal adhesive have permitted to obtain new interesting development in dental traumatology and dental aesthetic, like the possibility of the utilization of the dental fragment, of the incisor broken for a trauma. The new dentinal adhesive is the Gluma (Bayer). The Author describes the technique, the times, some particulars and step by step all the method to obtain good final results. The Author described complicated and uncomplicated crown fractures, fractures with several fragments and corono-radicular fractures with reattachment of the fragment. The long distances results (3 years) of 48 cases are presented. Finally are presented all the advantages compared to the traditional methods with the composites materials.
