Five-Year Marginal Bone-Level Changes Around Immediately Loaded or Immediately Restored Implants After Maxillary Sinus Floor Elevation: A Retrospective Cohort Analysis of Three Implant-Site Preparation Techniques
Background/Objectives: Peri-implant marginal bone stability is a relevant indicator of the medium-term outcomes of implants placed simultaneously with maxillary sinus floor elevation. This study aimed to describe peri-implant marginal bone levels after at least 60 months and to assess their association with three impla...
