Phase 4RecruitingNCT04552080

Medical University of Graz30 enrolled

Overview

The primary aim of the trial is to evaluate the effect of systemic antibiotic administration compared to placebo in patients undergoing oral implant therapy with simultaneous lateral sinus floor elevation and guided bone regeneration (GBR) in regard to patient-centered outcomes. The secondary aims of the trial is 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).
