Ectodermal dysplasias (ED) comprise a group of rare genetic disorders affecting ectodermal- derived tissues, including hair, teeth, nails, and sweat glands. These conditions result in significant functional and aesthetic impairments, greatly impacting patients’ quality of life. Among the rare forms, Papillon-Lefèvre Syndrome (PLS) and the most common form, Christ- Siemens-Touraine Syndrome (CST), present specific clinical challenges such as early tooth loss due to aggressive periodontitis or structural anomalies. This article highlights the multidisciplinary prosthetic management of two clinical cases. The first case involves an adolescent with PLS who underwent complete tooth extractions followed by conventional prosthetic rehabilitation. The second case focuses on a patient with CST, treated with partial removable prostheses tailored to their young age and developmental stage. These interventions aim to restore oral functions, enhance aesthetics, and improve the psychological well-being of the patients. ED presents challenges related to bone and dental anomalies, emphasizing the importance of early and multidisciplinary care. This approach focuses on preventing complications and maintaining an optimal quality of life. For growing patients, transitional prosthetic solutions are preferred, while implant-supported treatments are reserved for individuals who have completed skeletal development. An appropriate dental rehabilitation is critical to mitigating the functional and aesthetic disabilities caused by these conditions. Regular follow-up from the time of diagnosis is essential to ensure optimal treatment outcomes and address the psychosocial needs of the patients.
