The study aimed to document how different implant surfaces affect bone-to-implant apposition in human sinus grafts by comparing conventional implants with custom titanium microimplants.
Nine healthy volunteers underwent sinus augmentation, with experimental implants featuring two surface types: machined and MTX microtextured.
Results showed that the MTX surface achieved significantly higher bone-to-implant apposition (72.31%) compared to the machined surface (38.01%), with no significant influence from healing time or implant location.
