Amelogenesis imperfecta is an inherited disorder involving enamel formation that affects the appearance of the teeth to various degrees. Cosmetic rehabilitation of these patients has been open to a variety of treatment options. Complete-coverage restorations are often recommended. Patients are occasionally averse to this because of the extensive preparation of tooth structure or lack of financial means. In the past, conservative measures were inadequate because the lack of enamel bonding did not allow a durable restoration. Presently, with the use of glass-ionomer cements and dentinal adhesives, dentin-resin bond strengths are approaching those of etched enamel. This article discusses the use of glass-ionomer cement, dentinal priming agents, and etched enamel to create a strong bond between restorative material and tooth structure that provides not only satisfactory esthetics, but also a durable restoration.
牙釉质发育不全是一种涉及牙釉质形成的遗传性疾病,会不同程度地影响牙齿外观。这些患者的美容修复有多种治疗选择。通常推荐全冠修复。患者有时会因牙体组织大量预备或经济条件有限而不愿接受。过去,保守治疗方法并不充分,因为缺乏牙釉质粘结无法实现持久修复。目前,随着玻璃离子粘固剂和牙本质粘结剂的使用,牙本质 - 树脂粘结强度已接近酸蚀牙釉质的粘结强度。本文讨论了使用玻璃离子粘固剂、牙本质底漆和酸蚀牙釉质在修复材料与牙体组织之间建立牢固粘结,这种粘结不仅能提供令人满意的美观效果,还能实现持久修复。
