Abstract

Down syndrome patients generally have poor oral hygiene due to lack of awareness and ability to perform oral care, and there is a high risk of tooth loss. Also, they are characterized by small and irregular teeth and oligodontia, which makes it difficult to do prosthetic treatment. This article reports a case of implant hybrid prosthesis treatment of maxillary edentulous area in Down syndrome patient. The external shape of the final prosthesis was determined by using the mandibular artificial teeth to reflect the oligodontia of the mandible and the pontic areas were adjusted to facilitate oral hygiene care. As a result, aesthetically and functionally satisfactory results were obtained.
