Molar-incisor hypomineralization (MIH) is a qualitative developmental defect of enamel, which has been a daily concern in clinical practice owing to its difficult treatment.
An 11-year-old girl was admitted to the pediatric dental clinic with a symptom of severe hypersensitivity in the permanent molars owing to MIH. The treatment consisted of a simplified occlusal replica adapted technique with conventional glass ionomer cement in the MIH-affected molars, which involved laboratory and clinical stages. The patient was reexamined every 3 months, and after 18 months there was no additional tooth structure loss, restoration failure, or pain. This technique may be considered a feasible alternative to restore hypomineralized teeth owing to its reduced procedure time and good performance in the follow-up period of 18 months.
The technique successfully restored the function and shape of the affected teeth, decreasing the sensitivity by means of covering the demarcated MIH opacities.
磨牙-切牙牙釉质发育不全（MIH）是一种釉质的发育性质量缺陷，由于其治疗难度较大，在临床实践中一直备受关注。
一名 11 岁女孩因 MIH 导致恒牙重度过敏而到儿科牙科诊所就诊。治疗包括在 MIH 受累磨牙上采用简化的咬合复制适应技术和常规玻璃离子水门汀，该治疗分实验室和临床两个阶段。患者每 3 个月复查一次，18 个月后未见额外牙体结构丧失、修复失败或疼痛。该技术的操作时间较短，在 18 个月的随访期内表现良好，可被视为修复矿化不全牙的一种可行替代方法。
该技术成功恢复了受累牙齿的功能和形态，通过覆盖有界 MIH 不透明区来降低敏感性。
