乳牙固连研究进展

Research advances in tooth ankylosis

乳牙固连是指乳牙牙骨质与周围牙槽骨直接结合的一种少见的临床疾病,多伴有牙齿正常萌出过程中断进而使患牙的平面低于邻牙。目前,其病因尚未完全阐明,诊断标准存在争议,治疗方案选择也多是依据临床医生个人经验。如果乳牙固连不能及时诊断并干预,则会导致邻牙倾斜、对颌牙伸长、继承恒牙阻生以及其他并发症,但目前国内外尚缺乏规范的临床治疗指南。文章针对乳牙固连的病因和治疗方案研究进展进行综述。

Tooth ankylosis is a rare clinical disease,in which cementum and surrounding alveolar bone become fused directly,and most cases had lower occlusal plane than the adjacent teeth.So far,the etiology is still uncertain and the criteria of diagnosis is controversial;besides,treatment plan is formulated by dentists based on their personal experience.If there′s no early diagnosis or intervention,it often leads to tipping of the adjacent tooth,supra-eruption of the antagonists,impaction of the successor premolars and other severe complications.At present,there are no standardized clinical treatment guidelines.The paper summarizes the research progress in the causes and treatments of tooth ankylosis.
