Pages 431-437, Language: EnglishMarinello / Kruger-Huber / ScharerThe increasing use of oral endoprostheses has offered new alternatives for fixed and removable prosthesis design. However, the use of implants also requires the complex understanding and use of sound prosthodontic principles. The establishment of proper maxillomandibular relationships (vertical dimension, occlusal plane, curve of Spee, tooth arrangement), esthetics, and function are essential precursors to success. Although the usefulness of rehabilitation with overdentures supported by osseointegrated fixtures is sometimes underestimated, overdentures provide an adequate treatment alternative in indicated cases. A case is presented in which previous preprosthetic surgery had failed and subsequently an overdenture supported by osseointegrated fixtures was constructed.
