Monolithic CAD/CAM Complete Overdentures for a Pedodontic Patient with Dentinogenesis Imperfecta and Limited Prosthetic Space: A Clinical Report

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 gingivashade 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.
