This article considers a possible solution to prevent or manage spontaneous alveolar bone growth in ankylosed, infraoccluded teeth in adolescents after elective decoronation, allowing replacement resorption to take place, preserving the surrounding alveolar bone and enabling vertical bone development coronal to the decoronated segment.
Intrusions and avulsions constitute 0.5–3% of all traumatic dental injuries.1 Ankylosis often occurs following late replantation or repositioning of avulsed or severely intruded teeth. This can hinder jaw growth and alveolus development resulting in:
One possible solution to prevent or manage these complications is to consider decoronation of the teeth and bury the root. This can allow replacement resorption to take place, preserving the surrounding alveolar bone and enabling vertical bone development coronal to the decoronated segment.3,4
A 17-year-old male suffered avulsion of his UL1 at the age of 13. Following replantation, the tooth was discoloured and infraoccluded with compromised aesthetics (Figure 1a–k).
A 21-year-old male with traumatic luxation to UR1 which maintained a position labial and apical compared to the remaining anterior dentition. UL1 had avulsed and not replanted. Attempts at distraction using orthodontic forces to correct the vertical bone deficiency had failed. The aesthetics were challenging owing to missing centrals and space constraints (Figure 2a–k).
