Treatment of intruded permanent incisors: a multidisciplinary approach.
The case presented is a report of a healthy 11-year-old boy, who fell down and traumatized his four maxillary incisors. Both central incisors were deeply intruded with concomitant uncomplicated crown fractures, and both lateral incisors suffered concussion. The intruded teeth were repositioned using a removable orthodontic appliance and were endodontically treated 3 weeks after trauma. Tooth 11 became ankylosed 3 months post trauma, and tooth 21 was extruded to its original position after 5 months. Five months post-trauma, teeth 12 and 22 underwent necrosis and were endodontically treated. In addition, tooth 22 presented an external inflammatory root resorption that was arrested by calcium hydroxide paste after 3 months. A crown-lengthening procedure was performed on tooth 11 10 months post-trauma, exposing the clinical crown to a better condition for restoration. All 4 incisors were restored with a composite material, and the incisal edges of the central incisors were shaped at the same level. Two months after the crown lengthening procedure, spontaneous eruption occurred on tooth 11, that had been ankylosed. The restored incisal edge of tooth 11 was reduced to the same level of tooth 21. The patient is under periodical examination till a definitive orthodontic treatment can be performed.
