摘要 目的:针对传统牙科去冠器拆除牙冠时存在的不足,研制一种发力恒定且发力大小可调的牙科自动去冠器。方法:该去冠器由壳体、冠钩、传导机构、发力机构、击发机构5个部分组成。利用弹簧蓄力实现冠头在瞬间产生爆发力,破坏冠内黏固剂的黏结力,使全冠松动,继而脱落。结果:该去冠器可安全有效地拆除牙冠,并能解放出一只手来进行基牙和黏膜的保护。结论:该自动去冠器结构简单、操作使用方便,是一种可有效拆除固定修复体的器械,值得临床推广。 Objective To develop a dental crown remover with the strength provided constantly and adjusted freely.Methods The remover was composed of a shell, a crown hook, a conduction mechanism, a strength generating mechanism and a percussion mechanism. The spring had the explosive force formed in the crown head to destruct the cohesion of the cement. Results The remover could remove the crown, with one hand freed for the protection of abutment and mucous membrane. Conclusion The remover has simple structure and easy operation, and is worth popularizing clinically.
