Purpose: The aim of this histological and histomorphometric study was to compare the early peri‐implant endosseous healing properties of a dual acid‐etched (DAE) surface (Osseotite®, Implant Innovations Inc., Palm Beach Gardens, FL, USA) with a DAE surface modified with nanometer‐sized calcium phosphate (CaP) particles (NanoTite™, Implant Innovations Inc.) in grafted and mature maxillary bone. Materials and Methods: Fifteen patients received two mini‐implants, 1 with DAE surface (control) and 1 with a DAE + CaP surface (test), to fixate an iliac crest bone graft to the maxilla. A part of each mini‐implant was in contact with the grafted bone and a part extended into the native maxillary bone. After a healing period of 3 months, the specimens were harvested and analyzed. Results: Overall, a trend was seen for stronger bone response around the test mini‐implants in the native bone of the maxilla. However, only the old bone particles measured by percentages of bone‐to‐implant contact and bone area were statistically significant ( p = .025 and p = .042, respectively). Conclusions: The NanoTite surface increases the peri‐implant endosseous healing properties in the native bone of the maxilla compared with the Osseotite surface, while this difference was not visible in the bone graft area. This might be a result of the lower remodeling process of the graft.
