Children affected by dentinogenesis imperfecta (DI) require restorative techniques or prosthodontic management to minimize the functional and psychosocial impacts of the condition. In cases of excessive wear of the deciduous dentition and moderate cooperation from the child, removable complete overdenture prostheses are the most suitable treatment option. However, limited restorative space is a technical challenge for the placement of such prostheses. Advances in digital technologies can help assist in the fabrication of monolithic prostheses with reduced thickness. The present clinical report describes the management of a moderately cooperative 7-year-old patient suffering from DI with severe tooth wear, reduced restorative space, and a high smile line. The design and fabrication of complete overdentures were performed using a digital workflow. This innovative monochromatic monolithic approach combined with the use of gingiva-shade composite resin respected the available restorative space while obtaining a natural esthetic appearance. Such a strategy requires regular denture replacement according to the child's growth and loss of deciduous dentition. An additional aim is to obtain the cooperation needed for a future global fixed rehabilitation over time.
受牙本质生成不全(DI)影响的儿童需要进行修复技术或修复治疗管理,以最大程度地减少该疾病对功能和心理社会的影响。在乳牙过度磨损且儿童有一定配合度的情况下,可摘式全口覆盖义齿是最适合的治疗选择。然而,有限的修复空间是放置此类义齿的技术挑战。数字技术的进步可以帮助辅助制造厚度更小的整体式义齿。本临床报告描述了一位 7 岁、合作度尚可的 DI 患者的治疗情况,该患者存在严重的牙齿磨损、修复空间减少和高笑线。全口覆盖义齿的设计和制作采用数字化工作流程。这种创新的单色整体式方法结合使用牙龈色复合树脂,在获得自然美观效果的同时,尊重了可用的修复空间。这种策略需要根据儿童的生长和乳牙脱落情况定期更换义齿。另一个目标是随着时间的推移获得未来全口固定修复所需的合作。
