Pages 745-749, Language: EnglishRaghoebar, Gerry M. / Vissink, ArjanPlacement of endosseous implants in the maxilla has been proven to be a reliable treatment modality.

If there are no signs of maxillary sinusitis, augmentation of the resulting alveolar defect can be performed during the same procedure.
