Orthodontic extrusion with fixed appliances for treatment of intrusive luxation injuries: A prospective study of 28 permanent maxillary incisors.
Background: Limited evidence exists on the treatment options of tooth repositioning after intrusive luxation.
Aim: The study aimed to investigate the outcomes and complications of orthodontic extrusion in treating intruded maxillary permanent incisors.
Design: A prospective study was conducted involving 28 intruded maxillary permanent incisors treated with orthodontic extrusion, compared with a retrospective control group of 29 teeth that underwent spontaneous re-eruption. The success rate of tooth repositioning, as well as pulp condition, periodontal healing, and root development were assessed and compared.
Results: The success rate of orthodontic extrusion was 96.4%, excluding one tooth that was ankylosed before treatment. There were no significant differences in pulp condition between the orthodontic extrusion and control groups for teeth with immature root development. Teeth with mature root development in the orthodontic group, however, showed a significantly higher rate of pulp necrosis (100%, p < .05). Periodontal healing outcomes were similar across both groups, regardless of the maturity of root development. The root length continued increasing during orthodontic extrusion treatment.
Conclusions: Orthodontic extrusion treatment could effectively reposition moderately to severely intrusive permanent incisors, without increasing the risk of complications compared with spontaneous re-eruption.
期刊介绍：
The International Journal of Paediatric Dentistry was formed in 1991 by the merger of the Journals of the International Association of Paediatric Dentistry and the British Society of Paediatric Dentistry and is published bi-monthly. It has true international scope and aims to promote the highest standard of education, practice and research in paediatric dentistry world-wide.
International Journal of Paediatric Dentistry publishes papers on all aspects of paediatric dentistry including: growth and development, behaviour management, diagnosis, prevention, restorative treatment and issue relating to medically compromised children or those with disabilities. This peer-reviewed journal features scientific articles, reviews, case reports, clinical techniques, short communications and abstracts of current paediatric dental research. Analytical studies with a scientific novelty value are preferred to descriptive studies. Case reports illustrating unusual conditions and clinically relevant observations are acceptable but must be of sufficiently high quality to be considered for publication; particularly the illustrative material must be of the highest quality.
