Abstract
Ectopic eruption of the first permanent molar is prevalent in children, with a reported prevalence of up to 6%. Treatment options usually range from passive observation to active correction with orthodontic appliances like separators or distalising devices. This study outlines the step-by-step procedure for creating a 'pistol spring' system, which delivers a consistent, sustained force, reducing the need for frequent reactivation. The system is easy to fabricate, well-tolerated and enhances treatment efficiency, improving patient compliance and reducing chair-side time. The 'pistol spring' offers a cost-effective, time-efficient solution for managing ectopic first molars, particularly in paediatric patients with limited appointment availability.
期刊介绍：
The Journal of Orthodontics has an international circulation, publishing papers from throughout the world. The official journal of the British Orthodontic Society, it aims to publish high quality, evidence-based, clinically orientated or clinically relevant original research papers that will underpin evidence based orthodontic care. It particularly welcomes reports on prospective research into different treatment methods and techniques but also systematic reviews, meta-analyses and studies which will stimulate interest in new developments. Regular features include original papers on clinically relevant topics, clinical case reports, reviews of the orthodontic literature, editorials, book reviews, correspondence and other features of interest to the orthodontic community. The Journal is published in full colour throughout.
