The medical condition that the patients have in this trial is edentulism in a posterior maxillary quadrant of the mouth with a sinus pneumatisation/ decreased crestal bone heigh defect requiring augmentation and rehabilitation with 1-3 implants. We want to investigate the effect of amoxicillin after this procedure in terms of complications and patient-centered outcomes.

To evaluate the effect of systemic antibiotic administration on postsurgical complications, in patients undergoing oral implant therapy with simultaneous lateral approach sinus floor elevation and guided bone regeneration (GBR).
