This case report describes a minimally invasive step-by-step approach to treat a patient with amelogenesis imperfecta. This is a genetic developmental disorder of the dental enamel, which clinically manifests as white and dark discolorations of the teeth. The clinical examination did not reveal the true depth of the staining. Therefore, a step-wise treatment approach was chosen. The first step consisted of a home bleaching procedure, which led to a slight improvement of the esthetic appearance, but the stains were still clearly visible. The next step was the application of a microabrasion technique. This led to further improvement, but not to a satisfactory result for this patient who had high esthetic expectations. Thus, the third step was undertaken: it was planned to restore the maxillary incisors and canines with ceramic veneers. The dental technician prepared a wax-up, which served as a basis for a clinical mock-up. After discussing the mock-up and the treatment plan with the patient, crown lengthening was performed on teeth 11 and 23 to improve the pink esthetics. Subsequently, the teeth were prepared in a minimally invasive way and a final impression was taken. Following try-in, the six veneers were inserted with resin cement.
本病例报告描述了一种治疗牙釉质发育不全患者的微创分步治疗方法。这是一种牙釉质的遗传性发育障碍,临床上表现为牙齿的白色和深色变色。临床检查未揭示染色的真实深度。因此,选择了一种分步治疗方法。第一步包括家庭漂白程序,这使美观外观略有改善,但污渍仍清晰可见。下一步是应用微磨除技术。这进一步改善了情况,但对于这位对美观有很高期望的患者来说,结果并不令人满意。因此,进行了第三步:计划用陶瓷贴面修复上颌切牙和尖牙。牙科技师制作了一个蜡型,作为临床模型的基础。在与患者讨论模型和治疗计划后,对11号和23号牙进行了牙冠延长术以改善牙龈美学。随后,以微创方式对牙齿进行预备并取最终印模。试戴后,用树脂粘结剂插入六颗贴面。
